Low difficulty, rewarding bitcoin pools?

Until I can get a dedicated miner, does anyone know of any low difficulty or high reward pools? I'm not running with enough power to get a stable source of bitcoins, so I'm hoping to run with a few pools and make a profit.

Why i’m bullish on Zilliqa (long read)

Edit: TL;DR added in the comments
 
Hey all, I've been researching coins since 2017 and have gone through 100s of them in the last 3 years. I got introduced to blockchain via Bitcoin of course, analyzed Ethereum thereafter and from that moment I have a keen interest in smart contact platforms. I’m passionate about Ethereum but I find Zilliqa to have a better risk-reward ratio. Especially because Zilliqa has found an elegant balance between being secure, decentralized and scalable in my opinion.
 
Below I post my analysis of why from all the coins I went through I’m most bullish on Zilliqa (yes I went through Tezos, EOS, NEO, VeChain, Harmony, Algorand, Cardano etc.). Note that this is not investment advice and although it's a thorough analysis there is obviously some bias involved. Looking forward to what you all think!
 
Fun fact: the name Zilliqa is a play on ‘silica’ silicon dioxide which means “Silicon for the high-throughput consensus computer.”
 
This post is divided into (i) Technology, (ii) Business & Partnerships, and (iii) Marketing & Community. I’ve tried to make the technology part readable for a broad audience. If you’ve ever tried understanding the inner workings of Bitcoin and Ethereum you should be able to grasp most parts. Otherwise, just skim through and once you are zoning out head to the next part.
 
Technology and some more:
 
Introduction
 
The technology is one of the main reasons why I’m so bullish on Zilliqa. First thing you see on their website is: “Zilliqa is a high-performance, high-security blockchain platform for enterprises and next-generation applications.” These are some bold statements.
 
Before we deep dive into the technology let’s take a step back in time first as they have quite the history. The initial research paper from which Zilliqa originated dates back to August 2016: Elastico: A Secure Sharding Protocol For Open Blockchains where Loi Luu (Kyber Network) is one of the co-authors. Other ideas that led to the development of what Zilliqa has become today are: Bitcoin-NG, collective signing CoSi, ByzCoin and Omniledger.
 
The technical white paper was made public in August 2017 and since then they have achieved everything stated in the white paper and also created their own open source intermediate level smart contract language called Scilla (functional programming language similar to OCaml) too.
 
Mainnet is live since the end of January 2019 with daily transaction rates growing continuously. About a week ago mainnet reached 5 million transactions, 500.000+ addresses in total along with 2400 nodes keeping the network decentralized and secure. Circulating supply is nearing 11 billion and currently only mining rewards are left. The maximum supply is 21 billion with annual inflation being 7.13% currently and will only decrease with time.
 
Zilliqa realized early on that the usage of public cryptocurrencies and smart contracts were increasing but decentralized, secure, and scalable alternatives were lacking in the crypto space. They proposed to apply sharding onto a public smart contract blockchain where the transaction rate increases almost linear with the increase in the amount of nodes. More nodes = higher transaction throughput and increased decentralization. Sharding comes in many forms and Zilliqa uses network-, transaction- and computational sharding. Network sharding opens up the possibility of using transaction- and computational sharding on top. Zilliqa does not use state sharding for now. We’ll come back to this later.
 
Before we continue dissecting how Zilliqa achieves such from a technological standpoint it’s good to keep in mind that a blockchain being decentralised and secure and scalable is still one of the main hurdles in allowing widespread usage of decentralised networks. In my opinion this needs to be solved first before blockchains can get to the point where they can create and add large scale value. So I invite you to read the next section to grasp the underlying fundamentals. Because after all these premises need to be true otherwise there isn’t a fundamental case to be bullish on Zilliqa, right?
 
Down the rabbit hole
 
How have they achieved this? Let’s define the basics first: key players on Zilliqa are the users and the miners. A user is anybody who uses the blockchain to transfer funds or run smart contracts. Miners are the (shard) nodes in the network who run the consensus protocol and get rewarded for their service in Zillings (ZIL). The mining network is divided into several smaller networks called shards, which is also referred to as ‘network sharding’. Miners subsequently are randomly assigned to a shard by another set of miners called DS (Directory Service) nodes. The regular shards process transactions and the outputs of these shards are eventually combined by the DS shard as they reach consensus on the final state. More on how these DS shards reach consensus (via pBFT) will be explained later on.
 
The Zilliqa network produces two types of blocks: DS blocks and Tx blocks. One DS Block consists of 100 Tx Blocks. And as previously mentioned there are two types of nodes concerned with reaching consensus: shard nodes and DS nodes. Becoming a shard node or DS node is being defined by the result of a PoW cycle (Ethash) at the beginning of the DS Block. All candidate mining nodes compete with each other and run the PoW (Proof-of-Work) cycle for 60 seconds and the submissions achieving the highest difficulty will be allowed on the network. And to put it in perspective: the average difficulty for one DS node is ~ 2 Th/s equaling 2.000.000 Mh/s or 55 thousand+ GeForce GTX 1070 / 8 GB GPUs at 35.4 Mh/s. Each DS Block 10 new DS nodes are allowed. And a shard node needs to provide around 8.53 GH/s currently (around 240 GTX 1070s). Dual mining ETH/ETC and ZIL is possible and can be done via mining software such as Phoenix and Claymore. There are pools and if you have large amounts of hashing power (Ethash) available you could mine solo.
 
The PoW cycle of 60 seconds is a peak performance and acts as an entry ticket to the network. The entry ticket is called a sybil resistance mechanism and makes it incredibly hard for adversaries to spawn lots of identities and manipulate the network with these identities. And after every 100 Tx Blocks which corresponds to roughly 1,5 hour this PoW process repeats. In between these 1,5 hour, no PoW needs to be done meaning Zilliqa’s energy consumption to keep the network secure is low. For more detailed information on how mining works click here.
Okay, hats off to you. You have made it this far. Before we go any deeper down the rabbit hole we first must understand why Zilliqa goes through all of the above technicalities and understand a bit more what a blockchain on a more fundamental level is. Because the core of Zilliqa’s consensus protocol relies on the usage of pBFT (practical Byzantine Fault Tolerance) we need to know more about state machines and their function. Navigate to Viewblock, a Zilliqa block explorer, and just come back to this article. We will use this site to navigate through a few concepts.
 
We have established that Zilliqa is a public and distributed blockchain. Meaning that everyone with an internet connection can send ZILs, trigger smart contracts, etc. and there is no central authority who fully controls the network. Zilliqa and other public and distributed blockchains (like Bitcoin and Ethereum) can also be defined as state machines.
 
Taking the liberty of paraphrasing examples and definitions given by Samuel Brooks’ medium article, he describes the definition of a blockchain (like Zilliqa) as: “A peer-to-peer, append-only datastore that uses consensus to synchronize cryptographically-secure data”.
 
Next, he states that: "blockchains are fundamentally systems for managing valid state transitions”. For some more context, I recommend reading the whole medium article to get a better grasp of the definitions and understanding of state machines. Nevertheless, let’s try to simplify and compile it into a single paragraph. Take traffic lights as an example: all its states (red, amber, and green) are predefined, all possible outcomes are known and it doesn’t matter if you encounter the traffic light today or tomorrow. It will still behave the same. Managing the states of a traffic light can be done by triggering a sensor on the road or pushing a button resulting in one traffic lights’ state going from green to red (via amber) and another light from red to green.
 
With public blockchains like Zilliqa, this isn’t so straightforward and simple. It started with block #1 almost 1,5 years ago and every 45 seconds or so a new block linked to the previous block is being added. Resulting in a chain of blocks with transactions in it that everyone can verify from block #1 to the current #647.000+ block. The state is ever changing and the states it can find itself in are infinite. And while the traffic light might work together in tandem with various other traffic lights, it’s rather insignificant comparing it to a public blockchain. Because Zilliqa consists of 2400 nodes who need to work together to achieve consensus on what the latest valid state is while some of these nodes may have latency or broadcast issues, drop offline or are deliberately trying to attack the network, etc.
 
Now go back to the Viewblock page take a look at the amount of transaction, addresses, block and DS height and then hit refresh. Obviously as expected you see new incremented values on one or all parameters. And how did the Zilliqa blockchain manage to transition from a previous valid state to the latest valid state? By using pBFT to reach consensus on the latest valid state.
 
After having obtained the entry ticket, miners execute pBFT to reach consensus on the ever-changing state of the blockchain. pBFT requires a series of network communication between nodes, and as such there is no GPU involved (but CPU). Resulting in the total energy consumed to keep the blockchain secure, decentralized and scalable being low.
 
pBFT stands for practical Byzantine Fault Tolerance and is an optimization on the Byzantine Fault Tolerant algorithm. To quote Blockonomi: “In the context of distributed systems, Byzantine Fault Tolerance is the ability of a distributed computer network to function as desired and correctly reach a sufficient consensus despite malicious components (nodes) of the system failing or propagating incorrect information to other peers.” Zilliqa is such a distributed computer network and depends on the honesty of the nodes (shard and DS) to reach consensus and to continuously update the state with the latest block. If pBFT is a new term for you I can highly recommend the Blockonomi article.
 
The idea of pBFT was introduced in 1999 - one of the authors even won a Turing award for it - and it is well researched and applied in various blockchains and distributed systems nowadays. If you want more advanced information than the Blockonomi link provides click here. And if you’re in between Blockonomi and the University of Singapore read the Zilliqa Design Story Part 2 dating from October 2017.
Quoting from the Zilliqa tech whitepaper: “pBFT relies upon a correct leader (which is randomly selected) to begin each phase and proceed when the sufficient majority exists. In case the leader is byzantine it can stall the entire consensus protocol. To address this challenge, pBFT offers a view change protocol to replace the byzantine leader with another one.”
 
pBFT can tolerate ⅓ of the nodes being dishonest (offline counts as Byzantine = dishonest) and the consensus protocol will function without stalling or hiccups. Once there are more than ⅓ of dishonest nodes but no more than ⅔ the network will be stalled and a view change will be triggered to elect a new DS leader. Only when more than ⅔ of the nodes are dishonest (66%) double-spend attacks become possible.
 
If the network stalls no transactions can be processed and one has to wait until a new honest leader has been elected. When the mainnet was just launched and in its early phases, view changes happened regularly. As of today the last stalling of the network - and view change being triggered - was at the end of October 2019.
 
Another benefit of using pBFT for consensus besides low energy is the immediate finality it provides. Once your transaction is included in a block and the block is added to the chain it’s done. Lastly, take a look at this article where three types of finality are being defined: probabilistic, absolute and economic finality. Zilliqa falls under the absolute finality (just like Tendermint for example). Although lengthy already we skipped through some of the inner workings from Zilliqa’s consensus: read the Zilliqa Design Story Part 3 and you will be close to having a complete picture on it. Enough about PoW, sybil resistance mechanism, pBFT, etc. Another thing we haven’t looked at yet is the amount of decentralization.
 
Decentralisation
 
Currently, there are four shards, each one of them consisting of 600 nodes. 1 shard with 600 so-called DS nodes (Directory Service - they need to achieve a higher difficulty than shard nodes) and 1800 shard nodes of which 250 are shard guards (centralized nodes controlled by the team). The amount of shard guards has been steadily declining from 1200 in January 2019 to 250 as of May 2020. On the Viewblock statistics, you can see that many of the nodes are being located in the US but those are only the (CPU parts of the) shard nodes who perform pBFT. There is no data from where the PoW sources are coming. And when the Zilliqa blockchain starts reaching its transaction capacity limit, a network upgrade needs to be executed to lift the current cap of maximum 2400 nodes to allow more nodes and formation of more shards which will allow to network to keep on scaling according to demand.
Besides shard nodes there are also seed nodes. The main role of seed nodes is to serve as direct access points (for end-users and clients) to the core Zilliqa network that validates transactions. Seed nodes consolidate transaction requests and forward these to the lookup nodes (another type of nodes) for distribution to the shards in the network. Seed nodes also maintain the entire transaction history and the global state of the blockchain which is needed to provide services such as block explorers. Seed nodes in the Zilliqa network are comparable to Infura on Ethereum.
 
The seed nodes were first only operated by Zilliqa themselves, exchanges and Viewblock. Operators of seed nodes like exchanges had no incentive to open them for the greater public. They were centralised at first. Decentralisation at the seed nodes level has been steadily rolled out since March 2020 ( Zilliqa Improvement Proposal 3 ). Currently the amount of seed nodes is being increased, they are public-facing and at the same time PoS is applied to incentivize seed node operators and make it possible for ZIL holders to stake and earn passive yields. Important distinction: seed nodes are not involved with consensus! That is still PoW as entry ticket and pBFT for the actual consensus.
 
5% of the block rewards are being assigned to seed nodes (from the beginning in 2019) and those are being used to pay out ZIL stakers. The 5% block rewards with an annual yield of 10.03% translate to roughly 610 MM ZILs in total that can be staked. Exchanges use the custodial variant of staking and wallets like Moonlet will use the non-custodial version (starting in Q3 2020). Staking is being done by sending ZILs to a smart contract created by Zilliqa and audited by Quantstamp.
 
With a high amount of DS; shard nodes and seed nodes becoming more decentralized too, Zilliqa qualifies for the label of decentralized in my opinion.
 
Smart contracts
 
Let me start by saying I’m not a developer and my programming skills are quite limited. So I‘m taking the ELI5 route (maybe 12) but if you are familiar with Javascript, Solidity or specifically OCaml please head straight to Scilla - read the docs to get a good initial grasp of how Zilliqa’s smart contract language Scilla works and if you ask yourself “why another programming language?” check this article. And if you want to play around with some sample contracts in an IDE click here. The faucet can be found here. And more information on architecture, dapp development and API can be found on the Developer Portal.
If you are more into listening and watching: check this recent webinar explaining Zilliqa and Scilla. Link is time-stamped so you’ll start right away with a platform introduction, roadmap 2020 and afterwards a proper Scilla introduction.
 
Generalized: programming languages can be divided into being ‘object-oriented’ or ‘functional’. Here is an ELI5 given by software development academy: * “all programs have two basic components, data – what the program knows – and behavior – what the program can do with that data. So object-oriented programming states that combining data and related behaviors in one place, is called “object”, which makes it easier to understand how a particular program works. On the other hand, functional programming argues that data and behavior are different things and should be separated to ensure their clarity.” *
 
Scilla is on the functional side and shares similarities with OCaml: OCaml is a general-purpose programming language with an emphasis on expressiveness and safety. It has an advanced type system that helps catch your mistakes without getting in your way. It's used in environments where a single mistake can cost millions and speed matters, is supported by an active community, and has a rich set of libraries and development tools. For all its power, OCaml is also pretty simple, which is one reason it's often used as a teaching language.
 
Scilla is blockchain agnostic, can be implemented onto other blockchains as well, is recognized by academics and won a so-called Distinguished Artifact Award award at the end of last year.
 
One of the reasons why the Zilliqa team decided to create their own programming language focused on preventing smart contract vulnerabilities is that adding logic on a blockchain, programming, means that you cannot afford to make mistakes. Otherwise, it could cost you. It’s all great and fun blockchains being immutable but updating your code because you found a bug isn’t the same as with a regular web application for example. And with smart contracts, it inherently involves cryptocurrencies in some form thus value.
 
Another difference with programming languages on a blockchain is gas. Every transaction you do on a smart contract platform like Zilliqa or Ethereum costs gas. With gas you basically pay for computational costs. Sending a ZIL from address A to address B costs 0.001 ZIL currently. Smart contracts are more complex, often involve various functions and require more gas (if gas is a new concept click here ).
 
So with Scilla, similar to Solidity, you need to make sure that “every function in your smart contract will run as expected without hitting gas limits. An improper resource analysis may lead to situations where funds may get stuck simply because a part of the smart contract code cannot be executed due to gas limits. Such constraints are not present in traditional software systems”. Scilla design story part 1
 
Some examples of smart contract issues you’d want to avoid are: leaking funds, ‘unexpected changes to critical state variables’ (example: someone other than you setting his or her address as the owner of the smart contract after creation) or simply killing a contract.
 
Scilla also allows for formal verification. Wikipedia to the rescue: In the context of hardware and software systems, formal verification is the act of proving or disproving the correctness of intended algorithms underlying a system with respect to a certain formal specification or property, using formal methods of mathematics.
 
Formal verification can be helpful in proving the correctness of systems such as: cryptographic protocols, combinational circuits, digital circuits with internal memory, and software expressed as source code.
 
Scilla is being developed hand-in-hand with formalization of its semantics and its embedding into the Coq proof assistant — a state-of-the art tool for mechanized proofs about properties of programs.”
 
Simply put, with Scilla and accompanying tooling developers can be mathematically sure and proof that the smart contract they’ve written does what he or she intends it to do.
 
Smart contract on a sharded environment and state sharding
 
There is one more topic I’d like to touch on: smart contract execution in a sharded environment (and what is the effect of state sharding). This is a complex topic. I’m not able to explain it any easier than what is posted here. But I will try to compress the post into something easy to digest.
 
Earlier on we have established that Zilliqa can process transactions in parallel due to network sharding. This is where the linear scalability comes from. We can define simple transactions: a transaction from address A to B (Category 1), a transaction where a user interacts with one smart contract (Category 2) and the most complex ones where triggering a transaction results in multiple smart contracts being involved (Category 3). The shards are able to process transactions on their own without interference of the other shards. With Category 1 transactions that is doable, with Category 2 transactions sometimes if that address is in the same shard as the smart contract but with Category 3 you definitely need communication between the shards. Solving that requires to make a set of communication rules the protocol needs to follow in order to process all transactions in a generalised fashion.
 
And this is where the downsides of state sharding comes in currently. All shards in Zilliqa have access to the complete state. Yes the state size (0.1 GB at the moment) grows and all of the nodes need to store it but it also means that they don’t need to shop around for information available on other shards. Requiring more communication and adding more complexity.

Roadmap / Zilliqa 2.0
 
There is no strict defined roadmap but here are topics being worked on. And via the Zilliqa website there is also more information on the projects they are working on.
 
Business & Partnerships
 
It’s not only technology in which Zilliqa seems to be excelling as their ecosystem has been expanding and starting to grow rapidly. The project is on a mission to provide OpenFinance (OpFi) to the world and Singapore is the right place to be due to its progressive regulations and futuristic thinking. Singapore has taken a proactive approach towards cryptocurrencies by introducing the Payment Services Act 2019 (PS Act). Among other things, the PS Act will regulate intermediaries dealing with certain cryptocurrencies, with a particular focus on consumer protection and anti-money laundering. It will also provide a stable regulatory licensing and operating framework for cryptocurrency entities, effectively covering all crypto businesses and exchanges based in Singapore. According to PWC 82% of the surveyed executives in Singapore reported blockchain initiatives underway and 13% of them have already brought the initiatives live to the market. There is also an increasing list of organizations that are starting to provide digital payment services. Moreover, Singaporean blockchain developers Building Cities Beyond has recently created an innovation $15 million grant to encourage development on its ecosystem. This all suggests that Singapore tries to position itself as (one of) the leading blockchain hubs in the world.
 
Zilliqa seems to already take advantage of this and recently helped launch Hg Exchange on their platform, together with financial institutions PhillipCapital, PrimePartners and Fundnel. Hg Exchange, which is now approved by the Monetary Authority of Singapore (MAS), uses smart contracts to represent digital assets. Through Hg Exchange financial institutions worldwide can use Zilliqa's safe-by-design smart contracts to enable the trading of private equities. For example, think of companies such as Grab, Airbnb, SpaceX that are not available for public trading right now. Hg Exchange will allow investors to buy shares of private companies & unicorns and capture their value before an IPO. Anquan, the main company behind Zilliqa, has also recently announced that they became a partner and shareholder in TEN31 Bank, which is a fully regulated bank allowing for tokenization of assets and is aiming to bridge the gap between conventional banking and the blockchain world. If STOs, the tokenization of assets, and equity trading will continue to increase, then Zilliqa’s public blockchain would be the ideal candidate due to its strategic positioning, partnerships, regulatory compliance and the technology that is being built on top of it.
 
What is also very encouraging is their focus on banking the un(der)banked. They are launching a stablecoin basket starting with XSGD. As many of you know, stablecoins are currently mostly used for trading. However, Zilliqa is actively trying to broaden the use case of stablecoins. I recommend everybody to read this text that Amrit Kumar wrote (one of the co-founders). These stablecoins will be integrated in the traditional markets and bridge the gap between the crypto world and the traditional world. This could potentially revolutionize and legitimise the crypto space if retailers and companies will for example start to use stablecoins for payments or remittances, instead of it solely being used for trading.
 
Zilliqa also released their DeFi strategic roadmap (dating November 2019) which seems to be aligning well with their OpFi strategy. A non-custodial DEX is coming to Zilliqa made by Switcheo which allows cross-chain trading (atomic swaps) between ETH, EOS and ZIL based tokens. They also signed a Memorandum of Understanding for a (soon to be announced) USD stablecoin. And as Zilliqa is all about regulations and being compliant, I’m speculating on it to be a regulated USD stablecoin. Furthermore, XSGD is already created and visible on block explorer and XIDR (Indonesian Stablecoin) is also coming soon via StraitsX. Here also an overview of the Tech Stack for Financial Applications from September 2019. Further quoting Amrit Kumar on this:
 
There are two basic building blocks in DeFi/OpFi though: 1) stablecoins as you need a non-volatile currency to get access to this market and 2) a dex to be able to trade all these financial assets. The rest are built on top of these blocks.
 
So far, together with our partners and community, we have worked on developing these building blocks with XSGD as a stablecoin. We are working on bringing a USD-backed stablecoin as well. We will soon have a decentralised exchange developed by Switcheo. And with HGX going live, we are also venturing into the tokenization space. More to come in the future.”
 
Additionally, they also have this ZILHive initiative that injects capital into projects. There have been already 6 waves of various teams working on infrastructure, innovation and research, and they are not from ASEAN or Singapore only but global: see Grantees breakdown by country. Over 60 project teams from over 20 countries have contributed to Zilliqa's ecosystem. This includes individuals and teams developing wallets, explorers, developer toolkits, smart contract testing frameworks, dapps, etc. As some of you may know, Unstoppable Domains (UD) blew up when they launched on Zilliqa. UD aims to replace cryptocurrency addresses with a human-readable name and allows for uncensorable websites. Zilliqa will probably be the only one able to handle all these transactions onchain due to ability to scale and its resulting low fees which is why the UD team launched this on Zilliqa in the first place. Furthermore, Zilliqa also has a strong emphasis on security, compliance, and privacy, which is why they partnered with companies like Elliptic, ChainSecurity (part of PwC Switzerland), and Incognito. Their sister company Aqilliz (Zilliqa spelled backwards) focuses on revolutionizing the digital advertising space and is doing interesting things like using Zilliqa to track outdoor digital ads with companies like Foodpanda.
 
Zilliqa is listed on nearly all major exchanges, having several different fiat-gateways and recently have been added to Binance’s margin trading and futures trading with really good volume. They also have a very impressive team with good credentials and experience. They don't just have “tech people”. They have a mix of tech people, business people, marketeers, scientists, and more. Naturally, it's good to have a mix of people with different skill sets if you work in the crypto space.
 
Marketing & Community
 
Zilliqa has a very strong community. If you just follow their Twitter their engagement is much higher for a coin that has approximately 80k followers. They also have been ‘coin of the day’ by LunarCrush many times. LunarCrush tracks real-time cryptocurrency value and social data. According to their data, it seems Zilliqa has a more fundamental and deeper understanding of marketing and community engagement than almost all other coins. While almost all coins have been a bit frozen in the last months, Zilliqa seems to be on its own bull run. It was somewhere in the 100s a few months ago and is currently ranked #46 on CoinGecko. Their official Telegram also has over 20k people and is very active, and their community channel which is over 7k now is more active and larger than many other official channels. Their local communities also seem to be growing.
 
Moreover, their community started ‘Zillacracy’ together with the Zilliqa core team ( see www.zillacracy.com ). It’s a community-run initiative where people from all over the world are now helping with marketing and development on Zilliqa. Since its launch in February 2020 they have been doing a lot and will also run their own non-custodial seed node for staking. This seed node will also allow them to start generating revenue for them to become a self sustaining entity that could potentially scale up to become a decentralized company working in parallel with the Zilliqa core team. Comparing it to all the other smart contract platforms (e.g. Cardano, EOS, Tezos etc.) they don't seem to have started a similar initiative (correct me if I’m wrong though). This suggests in my opinion that these other smart contract platforms do not fully understand how to utilize the ‘power of the community’. This is something you cannot ‘buy with money’ and gives many projects in the space a disadvantage.
 
Zilliqa also released two social products called SocialPay and Zeeves. SocialPay allows users to earn ZILs while tweeting with a specific hashtag. They have recently used it in partnership with the Singapore Red Cross for a marketing campaign after their initial pilot program. It seems like a very valuable social product with a good use case. I can see a lot of traditional companies entering the space through this product, which they seem to suggest will happen. Tokenizing hashtags with smart contracts to get network effect is a very smart and innovative idea.
 
Regarding Zeeves, this is a tipping bot for Telegram. They already have 1000s of signups and they plan to keep upgrading it for more and more people to use it (e.g. they recently have added a quiz features). They also use it during AMAs to reward people in real-time. It’s a very smart approach to grow their communities and get familiar with ZIL. I can see this becoming very big on Telegram. This tool suggests, again, that the Zilliqa team has a deeper understanding of what the crypto space and community needs and is good at finding the right innovative tools to grow and scale.
 
To be honest, I haven’t covered everything (i’m also reaching the character limited haha). So many updates happening lately that it's hard to keep up, such as the International Monetary Fund mentioning Zilliqa in their report, custodial and non-custodial Staking, Binance Margin, Futures, Widget, entering the Indian market, and more. The Head of Marketing Colin Miles has also released this as an overview of what is coming next. And last but not least, Vitalik Buterin has been mentioning Zilliqa lately acknowledging Zilliqa and mentioning that both projects have a lot of room to grow. There is much more info of course and a good part of it has been served to you on a silver platter. I invite you to continue researching by yourself :-) And if you have any comments or questions please post here!

Consensus Mechanism of Wisdom Chain Document Knowledge Base

At present, there is a consensus mechanism in the global public chain infrastructure. It stipulates how to compete between the nodes. The most popular consensus mechanism at this stage is OW, POS, DPOS, PBFT and DBFT. Its speed, safety and centralization degree have different emphasis. However, some public chains choose to use the hybrid consensus mechanism, such as ZIL adopts the POW+PBFT's mixed consensus mechanism, Wisdom Chain adopts the DPOS+Pow's mixed consensus mechanism, and what is the advantage of adopting the hybrid consensus mechanism?
📷
First of all, the early Bitcoin and Ethereum adopted a single consensus mechanism, which resulted in their slow running speed and being unable to be used in the commercial environment. Although EOS uses the consensus mechanism of DPOS, all transactions are recorded by the super node on the chain, which has greatly improved the efficiency, but it has lost another major feature of the blockchain - the security brought by decentralization 。 Therefore, the public chain with a single consensus mechanism is doomed to not have both efficiency, security and decentralization. Advantages of hybrid mechanism The biggest advantage of hybrid mechanism is that it can learn from each other's strengths. Hybrid consensus means that two or more consensus mechanisms are applied to the underlying architecture of the same blockchain public chain. Reasonable use of mixed consensus can make up for the defects of low efficiency, loss of security protection or sacrifice of centralization degree caused by single consensus mechanism.
📷
Wisdom Chain's ideas in this regard are quite creative. It adopts the hybrid mechanism of DPOS+POW, and the two accounts run simultaneously to make up for the disadvantage of any single consensus mechanism. DPOS mechanism has high efficiency. It is responsible for selecting legal transactions from the transaction storage pool, packaging them into blocks, and then broadcasting them to the network through P2P protocol. The implied POW requires miners to complete a certain amount of work proof to prevent the main chain from branching. At the same time, the elimination mechanism is established. If the nodes make false accounts or biased records within 30 seconds, they will be eliminated. As a result, speed, security and decentralization are taken into account. Of course, there are still some problems to be solved in the hybrid consensus mechanism, but any technology is not achieved overnight, and it is impossible to have a smooth journey. However, the Wisdom Chain team made a detailed and in-depth thinking on the key technical difficulties and put forward feasible technical solutions. In the future, with the popularization of blockchain technology, the problem of hybrid consensus mechanism will surely be solved one by one.

The deepest report: Bitmain's self-help history

The deepest report: Bitmain's self-help history
The original intention of this article is to let readers understand the causes and consequences of Bitmain internal fighting, but after writing it, I found that it is not so much internal fighting as it is a long history of self-help.
The story is very long. Let's adjust the timeline to the eve of December 17, 2018. That was one of Bitmain's most critical moments and the beginning of a series of subsequent stories.
1. Self-immolation In September 2018, Bitmain's financial department warned management that the company's cash flow has become very tight and operating costs must be reduced to allow the company to continue. The blockchain unicorn, which is valued at more than 15 billion U.S. dollars, is crippled in the run and struggling to break the corner.
In 2017, Bitmain made a profit of 1 billion US dollars In the first half of 2018, Bitmain made a profit of 1 billion US dollars Three rounds of financing, a total of 800 million US dollars Net assets should exceed 3 billion U.S. dollars In September 2018, Bitmain had tight cash flow and was on the verge of bankruptcy
A simple comparison, it is not difficult to see that Bitmain's ability to make money is incredible, and its ability to burn money is even more extreme.
How does Bitmain burn money? Do you pour cash into gasoline and burn it, or hire a lot of employees to stuff the banknotes one by one into the shredder? The actual situation is closer to the latter.
The following data can help readers quickly learn Bitmain's money burning skills.
At the beginning of 2018, the entire cryptocurrency market has entered a bear market, but Bitmain's monthly operating costs have been rising wildly. Operating costs have risen from 10 million US dollars at the beginning of the year to 50 million US dollars at the end of the year.
Large-scale expansion of the R&D team is one of the main reasons. The HR who once worked at Bitmain revealed that the company once hired more than 50 employees a day and nearly 500 employees a month. Even so, it was criticized for its slow recruitment speed. The cash consumption in this area is approximately $250 million.
Operating costs are just the tip of the iceberg. Excessive chip trial production can become a classic case of project management courses. Readers who pay attention to Cryptocurrency mining can easily find that Bitmain is still working hard to clear the inventory of Antminer S9 in 2019. As the co-CEO, Ketuan Zhan did not listen to the advice or even warnings of the Finance Department, insisting on the implementation of Excessive chip trial production, resulting in a large accumulation of inventory and tight capital turnover. Another CEO, Jihan Wu, once revealed that the loss of Excessive chip trial production to the company was approximately US$1.5 billion.
Large-scale expansion of the R&D team is one of the main reasons. The HR who once worked at Bitmain revealed that the company once hired more than 50 employees a day and nearly 500 employees a month. Even so, it was criticized for its slow recruitment speed. The cash consumption in this area is approximately $250 million.
The BM1393 chip incident is even more incredible. Chip expert Ketuan Zhan invested a lot of money on a failed chip, and finally failed again. From 2017 to 2018, Bitmain has failed Trial production of mining machine chips at least 4 times, including 16nm, 12nm and 10nm chips, of which 16nm Trial production failed twice, thus losing at least US$1.2 billion.
It is rumored that Bitmain still holds a billion U.S. dollars worth of cryptocurrency in a state of floating loss. In view of the rebound in the market in 2020, we will not comment temporarily, waiting for the correct answer from the cryptocurrency market. But the losses pointed out in the previous article are all irreversible.
2. Sole power
In September 2018, Bitmain's management realized the seriousness of the problem. It turned out that the company's money could be squandered. As a result, the management began to discuss self-help plans, and the most reasonable and effective way was obviously to lay off employees.
The probation period for newly hired employees at Bitmain is half a year, and the probationary salary is 100% of the official salary, there is no difference. Once layoffs are made, new employees who have not passed the probationary period will be the main layoff targets. The department managed by Ketuan Zhan will face large-scale layoffs. The layoff plan is strongly opposed by Ketuan Zhan. Bitmain can only temporarily abandon the layoffs and replace it with continuous reductions. For marketing and travel expenses, a budget committee was established to strictly approve every expenditure. At the same time, employee benefits, such as reimbursement of taxi expenses, breakfast supply, snacks and drinks, etc., have also been abolished, and even the tradition of giving employees 400 yuan worth of BTC/BCH every month has been stopped.
In the face of huge cash flow pressure, trivial savings is obviously of no avail. Soon, the management again discussed the layoff plan, and it has reached the point where it has to be laid off.
In December 2018, Jihan Wu began to organize all entrepreneurial veterans and business backbones to persuade Ketuan Zhan to agree to layoffs, but Ketuan Zhan still insisted not to layoffs. The persuasion process was very unsuccessful. After many meetings and intense debates, Bitmain executives were caught in a dilemma of wasting time with Ketuan Zhan.
In this process, the shortcomings of the dual CEO system began to appear, and the relationship between the two CEOs gradually deteriorated.
On the night of December 16th, Ketuan Zhan reconvened the management meeting, and more than 30 managements who were present were asked to hand over their mobile phones. At this time, Jihan Wu was on a business trip in Hong Kong and was busy with listing related work.
In the meeting, Ketuan Zhan's core content was three items:
(1) Bitmain cannot have two CEOs, only one CEO and must be Ketuan Zhan. Ketuan Zhan said that he met an old leader during a business trip. He hadn't seen each other for many years. The old leader suggested that the company can only have one CEO, and it must be him. Ketuan Zhan feels that this is a kind of fate, an opportunity given by God.
(2) Ketuan Zhan believes that the company's cash flow problems, the biggest responsibility is the inability of the financial department. To prove his point, Ketuan Zhan announced Bitmain's financial data at the meeting. In the evening, employees in Taiwan began to post messages on social media, saying that the company's capital chain was broken and the top management was split.
(3) If Ketuan Zhan is not supported, the option will be cancelled and the equity will be voided.
Hearing about this, Jihan Wu, who lives in Hong Kong, sent a WeChat message to the management who are attending the meeting.

On the afternoon of December 17, 2018, Jihan Wu returned to Beijing to negotiate with Ketuan Zhan all night, and finally reached a consensus in the early morning. Bitmain co-founder Yuesheng Ge announced the results of the negotiations. Jihan Wu and Ketuan Zhan ceased to serve as CEOs, and Haichao Wang served as CEO. Jihan Wu voluntarily backed down and Ketuan Zhan served as chairman.
The "12.17 Incident" had a very bad impact on Bitmain, especially the disclosure of Bitmain's financial status, which caused vendors to start dunning. The loan that had just been negotiated with the Bank of Beijing was cancelled the next day. Jihan Wu's resignation as CEO caused an uproar in the industry, and it became a hot topic among Cryptocurrency mining, blockchain practitioners, and investor communities. The media focused their interpretation on Bitmain's series of incidents, and generally looked down upon its ongoing Hong Kong IPO, believing that the high-level changes had already signaled the failure of the IPO in advance.
On Christmas December 24, 2018, Bitmain finally began to implement the layoff plan. This long-delayed “correct decision” was achieved after a stalemate for nearly three months. The AI ​​teams in Beijing, Singapore, Taiwan, and Shanghai have laid off more than 50% of their employees. The Israeli R&D center was closed and Shenzhen New Species Technology Co., Ltd., which had been acquired for only ten months, was dissolved, and all employees were laid off. Copernicus, Bitmain's top blockchain development team, was not spared and was wiped out in this layoff. Copernicus and some of the laid-off employees joined the new company Matrixport co-founded by Jihan Wu and Yuesheng Ge, headquartered in Singapore.
3. Past events when starting a business
After the "12.17 Incident", Jihan Wu gradually faded out of Bitmain's management affairs and turned his attention to the IPO and new company. And this is one of Jihan Wu's major mistakes, he began to let Ketuan Zhan manage Bitmain alone.
In fact, as early as 2013, Jihan Wu planted hidden dangers.
Jihan Wu, an investment banker, was the earliest translator of the Bitcoin white paper. He began to get involved in the cryptocurrency mining industry in 2012. The disappearance of Kaomao and Nangua Zhang's ticket skipping led Jihan Wu to decide to develop his own chip.
In 2013, Jihan Wu established his own mining machine company. Together with Yuesheng Ge, who was only 20 years old, he found Ketuan Zhan, an integrated circuit designer of the Chinese Academy of Sciences, to create the protagonist of this article, and later the digital Cryptocurrency mining giant, Bitmain.
Jihan Wu promised Ketuan Zhan that every time a mining machine chip was successfully developed, he would give some shares to the Ketuan Zhan team. At that time, the company founded by Ketuan Zhan was on the eve of falling apart. In order to regroup the team, Ketuan Zhan promised to share half of his shares with the team members. Unfortunately, this is just a bad check. With the rapid development of Bitmain and higher and higher valuations, the expanding Ketuan Zhan almost monopolized all the shares.
Like many startups, Bitmain encountered many difficulties in its early days, and many jobs had to be done by the boss. For example, in the chip design and production process in the second half of 2013, Bitmain was caught in a dilemma of insufficient funds. Jihan Wu personally raised funds and met with TSMC’s sales to persuade TSMC to accept the production needs of a start-up company. Jihan Wu also participated in the selection of the thermodynamic parameters of the heat sink in the Antminer S1.
In 2014, Jihan Wu discovered that this company was independently operated by Ketuan Zhan, which had huge problems. Forcing Jihan Wu to continue to participate in company management.
At that time, Bitmain's mining machine chips had just achieved a certain lead in the standard design process. Jihan Wu believes that the next step must be to develop full customization technology, but Ketuan Zhan plans to invest resources in the research of mobile payment chips.
Ketuan Zhan met a mysterious person from the Party Central Security Bureau who claimed to be able to manipulate the Party Central Committee’s decision-making process for the next generation of mobile payment cryptography standards, but this direction is likely to lead to the fact that Bitmain has just gained the lead in the mining machine market. Regained.
Jihan Wu said that as a graduate of the School of Economics, with a little memory of his high school stage and the knowledge reserve of a computer technology amateur, he retrieves various materials and papers every day, learns theories related to full customization, and goes to Ketuan Zhan conducts persuasion work there.
Fortunately, in the direction of full customization technology, Ketuan Zhan finally listened to Jihan Wu's opinion. Bitmain quickly integrated the technical experts from the United States and Russia introduced by Jihan Wu, which greatly improved the design level of chips and complete machines.
In 2015, Jihan Wu suggested that Ketuan Zhan consider the direction of artificial intelligence. But Ketuan Zhan is not here, he prefers the CPU direction. After staying asleep at night, coupled with in-depth analysis by the Bitmain investment team, Ketuan Zhan finally agreed with this direction. It is a pity that after the Tianshi Chen brothers made major breakthroughs in theory and practice, Bitmain officially invested in the relevant direction, and it was still a step behind.
In the two years from 2016 to 2017, Bitmain's business performance has achieved rapid development, becoming a unique super unicorn in the blockchain industry. According to Froth & Sullivan, in 2017, Bitmain Technology Holdings was the second largest fabless chip design company in China and the tenth largest fabless chip design company in the world, and the fourth largest fabless ASIC chip design company in the world, accounting for 74.5% of global cryptocurrency market share.
However, the huge crisis has long been buried in the early days of entrepreneurship.
Ketuan Zhan's decision on major directions revealed his weakness of extremely lack of business understanding. But every mistake he made was blocked by the company's core employees. His overconfidence in his management ability led to the gradual intensification of conflicts, and the management differences between the two founders became more serious.
4.The giant gets lost
The contradiction between the two broke out on December 17, 2018. Ketuan Zhan used extreme means to force the management to compromise with him by canceling the option, so as to achieve the goal of sole control of the company. Jihan Wu returned to Beijing from Hong Kong overnight and negotiated with Ketuan Zhan all night. In the end, the two resigned as CEO. Jihan Wu retired. Ketuan Zhan has the exclusive rights of chairman in exchange for the implementation of the layoff plan.
Jihan Wu's voluntary retreat has intensified Ketuan Zhan's management to do whatever he wants.
A Bitmain employee commented on Ketuan Zhan's management skills, summed up in two letters-SM.
After becoming the sole helm of the company, Ketuan Zhan quickly "rectified" the department in charge of Jihan Wu as the chairman of the board. He guided the sales of mining machines at the dinner, and pointed out that the sales performance is not due to the sales staff. Ability is strong, but the company provides opportunities. Take two sales leaders as examples, saying that if the company hadn't given the opportunity, they would still be losers. In addition, Ketuan Zhan also instructed the sales staff on how to toast and imparted the wine table culture and experience.
After the meal, Ketuan Zhan came to the conclusion that the quality of Bitmain sales staff was too poor, and Huawei’s blood needs to be injected to drive the company’s progress. Soon, the marketing and sales director from Huawei officially took over Bitmain, opening the era of brand premium for Antminer.
In order to further understand and guide the sales work, Ketuan Zhan asked to meet the customers with the sales staff. During the negotiation process, Ketuan Zhan had a heated discussion with customers on the issue of Chinese and Western medicine, and had also forced the sales staff to be able to ship 10,000 machines due to insufficient production capacity.
Although the requirements for sales personnel are strict, Ketuan Zhan has provided a lot of convenience for "Mainland Ark". In addition to selling mining machines at a more favorable price, Bitmain's mining machines are also hosted in Ming Wang at a higher price than the market price. Mine. It is reported that both Ketuan Zhan and Ming Wang are shareholders of Ark.
The new sales strategy of Huawei's executives has also brought very obvious changes to Bitmain. The self-righteous brand premium reduces the price-performance ratio of Antminer, causing competing products to eat away at Bitmain's market share. Later, Bitmain found that the strategy was wrong and started to cut prices, and found that the mining machine market was saturated and the purchase demand of miners had decreased.
More dangerous than the sales strategy is that the technical advantages of Antminer are being chased by competing products, and even overtaken. At the same time, the two mining pools under Bitmain also lost their first and second positions. The AI ​​business, which Jihan Wu placed high hopes and Ketuan Zhan personally supervised, became a laughing stock in the industry. Not only did it fail to make a profit, it almost brought down Bitmain.
Blindly introducing senior executives from Huawei to occupy important positions completely destroys the company's internal cultural foundation. The bureaucracy within Bitmain began to corrode from high-level employees to ordinary employees. Ketuan Zhan is not aware of this. He is still keen on recruiting Huawei employees, imitating Huawei's organizational structure and strategy, letting HR do sales and R&D personnel to do HR.
The organizational structure adjustment in October 2019 was the fuse for Ketuan Zhan to completely anger Bitmain management. This time, Ketuan Zhan completely marginalized Bitmain’s veteran employees, and suddenly promoted some of the “airborne soldiers” who had just joined the company to the position of person in charge, which caused the former person in charge to report to the new employees. The two managers who were originally equal The hierarchy becomes the subordinate relationship, the operation and development of different business lines are merged into a large department, the upward reporting process becomes more cumbersome, and the relationship between employees becomes delicate.
5. Headwind
On October 29, 2019, Jihan Wu urgently held a staff meeting. Prior to this, the legal representative of Beijing Bitmain has been changed to Jihan Wu, including the parent companies Hong Kong Bitmain and Cayman Bitmain. Jihan Wu stood in the lobby of Building 25, B1, announcing that Ketuan Zhan has been relieved of all duties. Any employee in the Bitmain Group shall no longer execute Ketuan Zhan’s instructions and participate in any meetings convened by Ketuan Zhan. If there is any violation, the company will demotion and expel the company based on the severity of the circumstances. If losses are caused to the company, the company will be held accountable.
Jihan Wu's speech is very long, which can be summarized as follows:
(1) Ketuan Zhan has been relieved of all duties. Also expelled from the original Huawei company HR Zhi Wang introduced by Ketuan Zhan at the end of 2018. Zhi Wang’s reputation on Bitmain was extremely poor and was ridiculed by employees as "nine thousand years" (In ancient China, the emperor was called "ten thousand years old", and the prince was "eight thousand years old." However, in the Ming Dynasty, there was an eunuch who caused harm to the country and the people. He called himself "nine thousand years old", meaning that he was only A little lower than the emperor's level).
(2) Ketuan Zhan's ability to control the company's option incentive plan has disappeared, and it is no longer possible to cancel employees' options at will.
(3) The organizational structure adjustment plan led by Ketuan Zhan was suspended.
(4) We are optimistic about the future of AI business, but the premise is that the main business can continue to make profits in order to support the company's continued investment in AI business.
In the speech, Jihan Wu also told employees the whole story of the "12.17 Incident" and bluntly said that the company is not in good condition. If no measures are taken, Bitmain is likely to go bankrupt in three quarters and he must come back to save the company.
At this time, Ketuan Zhan, who was on a business trip in Shenzhen, finally experienced the situation of Jihan Wu in the "12.17 Incident".
After the official return, Jihan Wu began to clearly point out the company's various problems in operation and management, and went deep into each business line to understand the situation. In the mining machine sales department meeting, employees spoke enthusiastically, reflecting on the difficulties and opinions encountered in the work, the marketing and sales director from Huawei asked with a surprised look, "Why didn't these issues be reported to me before?", and soon , The director was interviewed and "voluntarily resigned."
On November 2, 2019, Jihan Wu announced a salary increase for all employees. Bitmain’s last salary increase dates back to 2018. In principle, Bitmain has two salary increases every year.
On November 7, 2019, Ketuan Zhan spoke on social media for the first time, describing his hardship in starting a business, and condemning Jihan Wu for “stabbing a knife in the back”. At the end of the article, he also set himself a KPI for 2020, that is, the mining machine market share will reach 90%, and the AI ​​business will earn 1 billion.
But Ketuan Zhan's majestic plan did not make Bitmain employees feel emotional, but ridiculed him instead. Employees exposed that he insulted employees, advocated Chinese medicine, believed in Buddhism, drank in meetings, practiced Qigong...
However, there is less than half a year before the halving of Bitcoin production, and the cryptocurrency market shows no signs of recovery, which makes Bitmain management very anxious.
On January 6, 2020, Bitmain ushered in another round of layoffs, with a layoff ratio of about 1/3. This time the layoffs have caused many employees who have just increased their salaries to feel very grieved. On the one hand, they were looking forward to Jihan Wu's return. On the other hand, the compensation for this layoff was less than 18 years.
Ketuan Zhan, who has been unable to enter the Bitmain office area, once again spoke on social media and firmly opposed to layoffs. We do not need to lay off staff and we cannot commit suicide.
During the Spring Festival, Covid-19 broke out. Mainland China has begun to extend the Spring Festival holiday and advocate working from home. Under the chain reaction caused by Covid-19, most companies have chosen to cut salaries or even lay off employees. In the first two months of 2020, China's exports fell by 17%, U.S. stocks were broken four times in a row, Bitcoin plunged 40% in 24 hours on March 12, 2020, and crude oil futures fell by 300% on April 20, 2020...
Obviously, Jihan Wu can't predict, but this layoff seems to be the right decision again. In addition, from January to April 2020, Bitmain's revenue exceeded US$400 million amid the spread of Covid-19 and the collapse of the financial market.
6. Fight to the death
When Jihan Wu tried to get the company back on track, Ketuan Zhan was not helpless. On April 28, 2020, Ketuan Zhan finally rolled back the legal representative of Beijing Bitmain to before October 28, 2019 by repeatedly submitting administrative reconsiderations, and restored his status as a legal representative.
On the morning of May 8, 2020, a piece of news about Bitmain quickly appeared on the real-time hot search rankings, and even dominated the headlines of the day. At window 52 on the second floor of the Haidian District Government Affairs Center, when Ketuan Zhan, the legal person of Beijing Bitmain Company, was receiving the business license, a group of unidentified people snatched the business license from the industrial and commercial administrative staff. A source at the scene said that the number of unidentified people in the group was about 60 people, of which Luyao Liu was directing at the scene.
This is a skillful piece of news. It first leads readers to think that Ketuan Zhan is a victim, using 60 people to grab business licenses as the focus. The masses accused Jihan Wu of lawlessness, but ignored whether the government affairs center could have 60 personnel. As for Hong Kong Bitmain to have the right to appoint a representative to obtain a business license, this is a deeper level of thinking.
The follow-up report restored the real situation at the scene. Only more than ten people were present, and both sides were equipped with security personnel. Bitmain employees also broke the news in the circle of friends, claiming that Ketuan Zhan's bodyguard had injured Bitmain's authorized person, and said in a threatening tone, "Be careful!"
However, the subsequent plot reversal did not have much effect. Jihan Wu's reputation has been greatly affected. From a bloody soldier who rescued the company in trouble to a lawless criminal, it can be said to be a world of war. do not.
Ketuan Zhan, who succeeded in the first battle, began to counterattack Bitmain continuously. On the afternoon of June 3, 2020, Ketuan Zhan led a team to pry open the back door of the Beijing Bitmain office and formally occupied the deserted Beijing headquarters.
On June 4, 2020, Ketuan Zhan called on Bitmain employees to resume work and promised to expand the company's market value to more than US$50 billion within three to five years. After that, Ketuan Zhan began to contact employees by phone, trying to acquire the options in the hands of employees at a valuation of 4 billion US dollars.
Subsequently, Ketuan Zhan recalled Huawei's executives and issued a series of personnel appointments and removals. As of June 9, 2020, Ketuan Zhan has successively eliminated CFO Luyao Liu, and Wenguang Wang, the head of the mining center. Luyao Liu is responsible for controlling Bitmain's IPO plan. He also appointed Yanwu Ma as the HR director, Gang Ren as the head of the mining center, Yonggang Sun as the head of the supply chain, Ling Gu as the financial director, and Bin Zhu as the head of the mining machine business department. Bin Zhu is the senior executive of Huawei who was interviewed and left as mentioned in the previous article. During his tenure, he reduced Antminer’s 90% market share to 50%, and received a large number of complaints from miners. Internal employees once speculated that he might be Compete against the spies sent by the company.
In addition to recalling senior executives of Huawei, Ketuan Zhan also urged employees to return to work. They can receive a bonus of 10,000 yuan when they return to work on the same day, which is only half the next day. Ketuan Zhan showed a very kind side. Every time the elevator door is opened, Ketuan Zhan's hot gaze can be met, shaking hands, taking photos, and receiving money. As there is no personnel information, Ketuan Zhan does not know whether the person receiving the money is a Bitmain employee, and these people did not resume work the next day.
The effect of gentleness was not good, Ketuan Zhan began to force employees to return to work. Seeing that there are still very few respondents, Ketuan Zhan threatened employees through SMS, phone calls, EMS, emails and other harassment, issued multiple threats such as termination of contract, suspension of payment of social insurance, suspension of wages, and even used personal information saved by employees to form a group of employees. Domicile threats, requiring employees to perform "work handover", trying to force employees to return work computers, etc.
On June 10, 2020, the media revealed that Ketuan Zhan had controlled Bitmain's Shenzhen factory and prohibited employees from delivering normal shipments to paid customers, which caused difficulties in the operation of the Bitmain mining machine department.
On June 13, 2020, Hong Kong Bitmain, the parent company of Beijing Bitmain, issued a statement accusing Ketuan Zhan of signing a "Sales Agency Agreement" with the Ark Data Technology Co., Ltd. in which it holds shares, in an attempt to embezzle Beijing Bit's assets.
On June 17, 2020, the media revealed that Ketuan Zhan started selling 14,000 T17+ series mining machines at low prices.
On June 20, 2020, Hong Kong Bitmain officially suspended the supply of chips to the Shenzhen factory.
On July 13, 2020, in the "A Letter to All My colleagues in the Shenzhen Factory" released by Bitmain in Hong Kong, more details were added on the series of Ketuan Zhan's actions in June.
The legal person Feng Zhou of the Shenzhen plant is related to Ketuan Zhan. After being relieved of Ketuan Zhan's post, Jihan Wu flew to Shenzhen to have a long talk with Feng Zhou. Jihan Wu believes that Feng Zhou is the right person to manage the factory and help the company overcome difficulties, and decides to leave Feng Zhou to continue to manage the factory.
This wrong decision staged a story of a farmer and a snake. When Ketuan Zhan began to counterattack Bitmain, Feng Zhou was also quickly instigated and began to assist Ketuan Zhan in seizing customer machines and transferring 17,000 T17 mining machines in the warehouse. Hainan Continental Ark Data Technology Co., Ltd., which is held by Ketuan Zhan, sold them at a low price.
In order to protect the interests of customers, Jihan Wu had to make a compromise and paid the payment for some goods to a bank account controlled by Ketuan Zhan in exchange for delivery. However, after the other party received a payment of 109 million, the delivery stopped. On July 8, 2020, 5600 mining machines have been overdue.
At the same time, the factory defaulted on suppliers’ accounts payable as much as 200 million yuan. Bank acceptance bills issued by the factory, exceeding 36 million yuan, will expire on July 17, and more than 34 million yuan will expire on July 23. It is understood that Ketuan Zhan, after receiving the bank's dunning call, made it clear that he would not repay the loan, which would destroy the company and the entire group's credit in financial institutions.
7、 This is not the end
So far, the power struggle between the founders of Bitmain has been more than half a year. The office building already occupied by Ketuan Zhan is still empty, and most employees choose to work from home. Some chip developers returned to the office with the acquiescence of Jihan Wu and continued to maintain research and development to reduce the impact of infighting on technological iteration and competitiveness.
This giant ship that once stood on top of the supercomputer chip is crashing into the iceberg due to the madness of the former helm. Ketuan Zhan's madness and Jihan Wu's compromise made mistakes again and again. Bitmain tried to save himself many times, but was unable to get out of the black hole.
If the time goes back to that day in 2013, would Jihan Wu and Yuesheng Ge still choose to dial Ketuan Zhan?

The deepest report: Bitmain's self-help history

The deepest report: Bitmain's self-help history
The original intention of this article is to let readers understand the causes and consequences of Bitmain internal fighting, but after writing it, I found that it is not so much internal fighting as it is a long history of self-help.
The story is very long. Let's adjust the timeline to the eve of December 17, 2018. That was one of Bitmain's most critical moments and the beginning of a series of subsequent stories.
1. Self-immolation In September 2018, Bitmain's financial department warned management that the company's cash flow has become very tight and operating costs must be reduced to allow the company to continue. The blockchain unicorn, which is valued at more than 15 billion U.S. dollars, is crippled in the run and struggling to break the corner.
In 2017, Bitmain made a profit of 1 billion US dollars In the first half of 2018, Bitmain made a profit of 1 billion US dollars Three rounds of financing, a total of 800 million US dollars Net assets should exceed 3 billion U.S. dollars In September 2018, Bitmain had tight cash flow and was on the verge of bankruptcy
A simple comparison, it is not difficult to see that Bitmain's ability to make money is incredible, and its ability to burn money is even more extreme.
How does Bitmain burn money? Do you pour cash into gasoline and burn it, or hire a lot of employees to stuff the banknotes one by one into the shredder? The actual situation is closer to the latter.
The following data can help readers quickly learn Bitmain's money burning skills.
At the beginning of 2018, the entire cryptocurrency market has entered a bear market, but Bitmain's monthly operating costs have been rising wildly. Operating costs have risen from 10 million US dollars at the beginning of the year to 50 million US dollars at the end of the year.
Large-scale expansion of the R&D team is one of the main reasons. The HR who once worked at Bitmain revealed that the company once hired more than 50 employees a day and nearly 500 employees a month. Even so, it was criticized for its slow recruitment speed. The cash consumption in this area is approximately $250 million.
Operating costs are just the tip of the iceberg. Excessive chip trial production can become a classic case of project management courses. Readers who pay attention to Cryptocurrency mining can easily find that Bitmain is still working hard to clear the inventory of Antminer S9 in 2019. As the co-CEO, Ketuan Zhan did not listen to the advice or even warnings of the Finance Department, insisting on the implementation of Excessive chip trial production, resulting in a large accumulation of inventory and tight capital turnover. Another CEO, Jihan Wu, once revealed that the loss of Excessive chip trial production to the company was approximately US$1.5 billion.
Large-scale expansion of the R&D team is one of the main reasons. The HR who once worked at Bitmain revealed that the company once hired more than 50 employees a day and nearly 500 employees a month. Even so, it was criticized for its slow recruitment speed. The cash consumption in this area is approximately $250 million.
The BM1393 chip incident is even more incredible. Chip expert Ketuan Zhan invested a lot of money on a failed chip, and finally failed again. From 2017 to 2018, Bitmain has failed Trial production of mining machine chips at least 4 times, including 16nm, 12nm and 10nm chips, of which 16nm Trial production failed twice, thus losing at least US$1.2 billion.
It is rumored that Bitmain still holds a billion U.S. dollars worth of cryptocurrency in a state of floating loss. In view of the rebound in the market in 2020, we will not comment temporarily, waiting for the correct answer from the cryptocurrency market. But the losses pointed out in the previous article are all irreversible.
2. Sole power
In September 2018, Bitmain's management realized the seriousness of the problem. It turned out that the company's money could be squandered. As a result, the management began to discuss self-help plans, and the most reasonable and effective way was obviously to lay off employees.
The probation period for newly hired employees at Bitmain is half a year, and the probationary salary is 100% of the official salary, there is no difference. Once layoffs are made, new employees who have not passed the probationary period will be the main layoff targets. The department managed by Ketuan Zhan will face large-scale layoffs. The layoff plan is strongly opposed by Ketuan Zhan. Bitmain can only temporarily abandon the layoffs and replace it with continuous reductions. For marketing and travel expenses, a budget committee was established to strictly approve every expenditure. At the same time, employee benefits, such as reimbursement of taxi expenses, breakfast supply, snacks and drinks, etc., have also been abolished, and even the tradition of giving employees 400 yuan worth of BTC/BCH every month has been stopped.
In the face of huge cash flow pressure, trivial savings is obviously of no avail. Soon, the management again discussed the layoff plan, and it has reached the point where it has to be laid off.
In December 2018, Jihan Wu began to organize all entrepreneurial veterans and business backbones to persuade Ketuan Zhan to agree to layoffs, but Ketuan Zhan still insisted not to layoffs. The persuasion process was very unsuccessful. After many meetings and intense debates, Bitmain executives were caught in a dilemma of wasting time with Ketuan Zhan.
In this process, the shortcomings of the dual CEO system began to appear, and the relationship between the two CEOs gradually deteriorated.
On the night of December 16th, Ketuan Zhan reconvened the management meeting, and more than 30 managements who were present were asked to hand over their mobile phones. At this time, Jihan Wu was on a business trip in Hong Kong and was busy with listing related work.
In the meeting, Ketuan Zhan's core content was three items:
(1) Bitmain cannot have two CEOs, only one CEO and must be Ketuan Zhan. Ketuan Zhan said that he met an old leader during a business trip. He hadn't seen each other for many years. The old leader suggested that the company can only have one CEO, and it must be him. Ketuan Zhan feels that this is a kind of fate, an opportunity given by God.
(2) Ketuan Zhan believes that the company's cash flow problems, the biggest responsibility is the inability of the financial department. To prove his point, Ketuan Zhan announced Bitmain's financial data at the meeting. In the evening, employees in Taiwan began to post messages on social media, saying that the company's capital chain was broken and the top management was split.
(3) If Ketuan Zhan is not supported, the option will be cancelled and the equity will be voided.
Hearing about this, Jihan Wu, who lives in Hong Kong, sent a WeChat message to the management who are attending the meeting.

On the afternoon of December 17, 2018, Jihan Wu returned to Beijing to negotiate with Ketuan Zhan all night, and finally reached a consensus in the early morning. Bitmain co-founder Yuesheng Ge announced the results of the negotiations. Jihan Wu and Ketuan Zhan ceased to serve as CEOs, and Haichao Wang served as CEO. Jihan Wu voluntarily backed down and Ketuan Zhan served as chairman.
The "12.17 Incident" had a very bad impact on Bitmain, especially the disclosure of Bitmain's financial status, which caused vendors to start dunning. The loan that had just been negotiated with the Bank of Beijing was cancelled the next day. Jihan Wu's resignation as CEO caused an uproar in the industry, and it became a hot topic among Cryptocurrency mining, blockchain practitioners, and investor communities. The media focused their interpretation on Bitmain's series of incidents, and generally looked down upon its ongoing Hong Kong IPO, believing that the high-level changes had already signaled the failure of the IPO in advance.
On Christmas December 24, 2018, Bitmain finally began to implement the layoff plan. This long-delayed “correct decision” was achieved after a stalemate for nearly three months. The AI ​​teams in Beijing, Singapore, Taiwan, and Shanghai have laid off more than 50% of their employees. The Israeli R&D center was closed and Shenzhen New Species Technology Co., Ltd., which had been acquired for only ten months, was dissolved, and all employees were laid off. Copernicus, Bitmain's top blockchain development team, was not spared and was wiped out in this layoff. Copernicus and some of the laid-off employees joined the new company Matrixport co-founded by Jihan Wu and Yuesheng Ge, headquartered in Singapore.
3. Past events when starting a business
After the "12.17 Incident", Jihan Wu gradually faded out of Bitmain's management affairs and turned his attention to the IPO and new company. And this is one of Jihan Wu's major mistakes, he began to let Ketuan Zhan manage Bitmain alone.
In fact, as early as 2013, Jihan Wu planted hidden dangers.
Jihan Wu, an investment banker, was the earliest translator of the Bitcoin white paper. He began to get involved in the cryptocurrency mining industry in 2012. The disappearance of Kaomao and Nangua Zhang's ticket skipping led Jihan Wu to decide to develop his own chip.
In 2013, Jihan Wu established his own mining machine company. Together with Yuesheng Ge, who was only 20 years old, he found Ketuan Zhan, an integrated circuit designer of the Chinese Academy of Sciences, to create the protagonist of this article, and later the digital Cryptocurrency mining giant, Bitmain.
Jihan Wu promised Ketuan Zhan that every time a mining machine chip was successfully developed, he would give some shares to the Ketuan Zhan team. At that time, the company founded by Ketuan Zhan was on the eve of falling apart. In order to regroup the team, Ketuan Zhan promised to share half of his shares with the team members. Unfortunately, this is just a bad check. With the rapid development of Bitmain and higher and higher valuations, the expanding Ketuan Zhan almost monopolized all the shares.
Like many startups, Bitmain encountered many difficulties in its early days, and many jobs had to be done by the boss. For example, in the chip design and production process in the second half of 2013, Bitmain was caught in a dilemma of insufficient funds. Jihan Wu personally raised funds and met with TSMC’s sales to persuade TSMC to accept the production needs of a start-up company. Jihan Wu also participated in the selection of the thermodynamic parameters of the heat sink in the Antminer S1.
In 2014, Jihan Wu discovered that this company was independently operated by Ketuan Zhan, which had huge problems. Forcing Jihan Wu to continue to participate in company management.
At that time, Bitmain's mining machine chips had just achieved a certain lead in the standard design process. Jihan Wu believes that the next step must be to develop full customization technology, but Ketuan Zhan plans to invest resources in the research of mobile payment chips.
Ketuan Zhan met a mysterious person from the Party Central Security Bureau who claimed to be able to manipulate the Party Central Committee’s decision-making process for the next generation of mobile payment cryptography standards, but this direction is likely to lead to the fact that Bitmain has just gained the lead in the mining machine market. Regained.
Jihan Wu said that as a graduate of the School of Economics, with a little memory of his high school stage and the knowledge reserve of a computer technology amateur, he retrieves various materials and papers every day, learns theories related to full customization, and goes to Ketuan Zhan conducts persuasion work there.
Fortunately, in the direction of full customization technology, Ketuan Zhan finally listened to Jihan Wu's opinion. Bitmain quickly integrated the technical experts from the United States and Russia introduced by Jihan Wu, which greatly improved the design level of chips and complete machines.
In 2015, Jihan Wu suggested that Ketuan Zhan consider the direction of artificial intelligence. But Ketuan Zhan is not here, he prefers the CPU direction. After staying asleep at night, coupled with in-depth analysis by the Bitmain investment team, Ketuan Zhan finally agreed with this direction. It is a pity that after the Tianshi Chen brothers made major breakthroughs in theory and practice, Bitmain officially invested in the relevant direction, and it was still a step behind.
In the two years from 2016 to 2017, Bitmain's business performance has achieved rapid development, becoming a unique super unicorn in the blockchain industry. According to Froth & Sullivan, in 2017, Bitmain Technology Holdings was the second largest fabless chip design company in China and the tenth largest fabless chip design company in the world, and the fourth largest fabless ASIC chip design company in the world, accounting for 74.5% of global cryptocurrency market share.
However, the huge crisis has long been buried in the early days of entrepreneurship.
Ketuan Zhan's decision on major directions revealed his weakness of extremely lack of business understanding. But every mistake he made was blocked by the company's core employees. His overconfidence in his management ability led to the gradual intensification of conflicts, and the management differences between the two founders became more serious.
4.The giant gets lost
The contradiction between the two broke out on December 17, 2018. Ketuan Zhan used extreme means to force the management to compromise with him by canceling the option, so as to achieve the goal of sole control of the company. Jihan Wu returned to Beijing from Hong Kong overnight and negotiated with Ketuan Zhan all night. In the end, the two resigned as CEO. Jihan Wu retired. Ketuan Zhan has the exclusive rights of chairman in exchange for the implementation of the layoff plan.
Jihan Wu's voluntary retreat has intensified Ketuan Zhan's management to do whatever he wants.
A Bitmain employee commented on Ketuan Zhan's management skills, summed up in two letters-SM.
After becoming the sole helm of the company, Ketuan Zhan quickly "rectified" the department in charge of Jihan Wu as the chairman of the board. He guided the sales of mining machines at the dinner, and pointed out that the sales performance is not due to the sales staff. Ability is strong, but the company provides opportunities. Take two sales leaders as examples, saying that if the company hadn't given the opportunity, they would still be losers. In addition, Ketuan Zhan also instructed the sales staff on how to toast and imparted the wine table culture and experience.
After the meal, Ketuan Zhan came to the conclusion that the quality of Bitmain sales staff was too poor, and Huawei’s blood needs to be injected to drive the company’s progress. Soon, the marketing and sales director from Huawei officially took over Bitmain, opening the era of brand premium for Antminer.
In order to further understand and guide the sales work, Ketuan Zhan asked to meet the customers with the sales staff. During the negotiation process, Ketuan Zhan had a heated discussion with customers on the issue of Chinese and Western medicine, and had also forced the sales staff to be able to ship 10,000 machines due to insufficient production capacity.
Although the requirements for sales personnel are strict, Ketuan Zhan has provided a lot of convenience for "Mainland Ark". In addition to selling mining machines at a more favorable price, Bitmain's mining machines are also hosted in Ming Wang at a higher price than the market price. Mine. It is reported that both Ketuan Zhan and Ming Wang are shareholders of Ark.
The new sales strategy of Huawei's executives has also brought very obvious changes to Bitmain. The self-righteous brand premium reduces the price-performance ratio of Antminer, causing competing products to eat away at Bitmain's market share. Later, Bitmain found that the strategy was wrong and started to cut prices, and found that the mining machine market was saturated and the purchase demand of miners had decreased.
More dangerous than the sales strategy is that the technical advantages of Antminer are being chased by competing products, and even overtaken. At the same time, the two mining pools under Bitmain also lost their first and second positions. The AI ​​business, which Jihan Wu placed high hopes and Ketuan Zhan personally supervised, became a laughing stock in the industry. Not only did it fail to make a profit, it almost brought down Bitmain.
Blindly introducing senior executives from Huawei to occupy important positions completely destroys the company's internal cultural foundation. The bureaucracy within Bitmain began to corrode from high-level employees to ordinary employees. Ketuan Zhan is not aware of this. He is still keen on recruiting Huawei employees, imitating Huawei's organizational structure and strategy, letting HR do sales and R&D personnel to do HR.
The organizational structure adjustment in October 2019 was the fuse for Ketuan Zhan to completely anger Bitmain management. This time, Ketuan Zhan completely marginalized Bitmain’s veteran employees, and suddenly promoted some of the “airborne soldiers” who had just joined the company to the position of person in charge, which caused the former person in charge to report to the new employees. The two managers who were originally equal The hierarchy becomes the subordinate relationship, the operation and development of different business lines are merged into a large department, the upward reporting process becomes more cumbersome, and the relationship between employees becomes delicate.
5. Headwind
On October 29, 2019, Jihan Wu urgently held a staff meeting. Prior to this, the legal representative of Beijing Bitmain has been changed to Jihan Wu, including the parent companies Hong Kong Bitmain and Cayman Bitmain. Jihan Wu stood in the lobby of Building 25, B1, announcing that Ketuan Zhan has been relieved of all duties. Any employee in the Bitmain Group shall no longer execute Ketuan Zhan’s instructions and participate in any meetings convened by Ketuan Zhan. If there is any violation, the company will demotion and expel the company based on the severity of the circumstances. If losses are caused to the company, the company will be held accountable.
Jihan Wu's speech is very long, which can be summarized as follows:
(1) Ketuan Zhan has been relieved of all duties. Also expelled from the original Huawei company HR Zhi Wang introduced by Ketuan Zhan at the end of 2018. Zhi Wang’s reputation on Bitmain was extremely poor and was ridiculed by employees as "nine thousand years" (In ancient China, the emperor was called "ten thousand years old", and the prince was "eight thousand years old." However, in the Ming Dynasty, there was an eunuch who caused harm to the country and the people. He called himself "nine thousand years old", meaning that he was only A little lower than the emperor's level).
(2) Ketuan Zhan's ability to control the company's option incentive plan has disappeared, and it is no longer possible to cancel employees' options at will.
(3) The organizational structure adjustment plan led by Ketuan Zhan was suspended.
(4) We are optimistic about the future of AI business, but the premise is that the main business can continue to make profits in order to support the company's continued investment in AI business.
In the speech, Jihan Wu also told employees the whole story of the "12.17 Incident" and bluntly said that the company is not in good condition. If no measures are taken, Bitmain is likely to go bankrupt in three quarters and he must come back to save the company.
At this time, Ketuan Zhan, who was on a business trip in Shenzhen, finally experienced the situation of Jihan Wu in the "12.17 Incident".
After the official return, Jihan Wu began to clearly point out the company's various problems in operation and management, and went deep into each business line to understand the situation. In the mining machine sales department meeting, employees spoke enthusiastically, reflecting on the difficulties and opinions encountered in the work, the marketing and sales director from Huawei asked with a surprised look, "Why didn't these issues be reported to me before?", and soon , The director was interviewed and "voluntarily resigned."
On November 2, 2019, Jihan Wu announced a salary increase for all employees. Bitmain’s last salary increase dates back to 2018. In principle, Bitmain has two salary increases every year.
On November 7, 2019, Ketuan Zhan spoke on social media for the first time, describing his hardship in starting a business, and condemning Jihan Wu for “stabbing a knife in the back”. At the end of the article, he also set himself a KPI for 2020, that is, the mining machine market share will reach 90%, and the AI ​​business will earn 1 billion.
But Ketuan Zhan's majestic plan did not make Bitmain employees feel emotional, but ridiculed him instead. Employees exposed that he insulted employees, advocated Chinese medicine, believed in Buddhism, drank in meetings, practiced Qigong...
However, there is less than half a year before the halving of Bitcoin production, and the cryptocurrency market shows no signs of recovery, which makes Bitmain management very anxious.
On January 6, 2020, Bitmain ushered in another round of layoffs, with a layoff ratio of about 1/3. This time the layoffs have caused many employees who have just increased their salaries to feel very grieved. On the one hand, they were looking forward to Jihan Wu's return. On the other hand, the compensation for this layoff was less than 18 years.
Ketuan Zhan, who has been unable to enter the Bitmain office area, once again spoke on social media and firmly opposed to layoffs. We do not need to lay off staff and we cannot commit suicide.
During the Spring Festival, Covid-19 broke out. Mainland China has begun to extend the Spring Festival holiday and advocate working from home. Under the chain reaction caused by Covid-19, most companies have chosen to cut salaries or even lay off employees. In the first two months of 2020, China's exports fell by 17%, U.S. stocks were broken four times in a row, Bitcoin plunged 40% in 24 hours on March 12, 2020, and crude oil futures fell by 300% on April 20, 2020...
Obviously, Jihan Wu can't predict, but this layoff seems to be the right decision again. In addition, from January to April 2020, Bitmain's revenue exceeded US$400 million amid the spread of Covid-19 and the collapse of the financial market.
6. Fight to the death
When Jihan Wu tried to get the company back on track, Ketuan Zhan was not helpless. On April 28, 2020, Ketuan Zhan finally rolled back the legal representative of Beijing Bitmain to before October 28, 2019 by repeatedly submitting administrative reconsiderations, and restored his status as a legal representative.
On the morning of May 8, 2020, a piece of news about Bitmain quickly appeared on the real-time hot search rankings, and even dominated the headlines of the day. At window 52 on the second floor of the Haidian District Government Affairs Center, when Ketuan Zhan, the legal person of Beijing Bitmain Company, was receiving the business license, a group of unidentified people snatched the business license from the industrial and commercial administrative staff. A source at the scene said that the number of unidentified people in the group was about 60 people, of which Luyao Liu was directing at the scene.
This is a skillful piece of news. It first leads readers to think that Ketuan Zhan is a victim, using 60 people to grab business licenses as the focus. The masses accused Jihan Wu of lawlessness, but ignored whether the government affairs center could have 60 personnel. As for Hong Kong Bitmain to have the right to appoint a representative to obtain a business license, this is a deeper level of thinking.
The follow-up report restored the real situation at the scene. Only more than ten people were present, and both sides were equipped with security personnel. Bitmain employees also broke the news in the circle of friends, claiming that Ketuan Zhan's bodyguard had injured Bitmain's authorized person, and said in a threatening tone, "Be careful!"
However, the subsequent plot reversal did not have much effect. Jihan Wu's reputation has been greatly affected. From a bloody soldier who rescued the company in trouble to a lawless criminal, it can be said to be a world of war. do not.
Ketuan Zhan, who succeeded in the first battle, began to counterattack Bitmain continuously. On the afternoon of June 3, 2020, Ketuan Zhan led a team to pry open the back door of the Beijing Bitmain office and formally occupied the deserted Beijing headquarters.
On June 4, 2020, Ketuan Zhan called on Bitmain employees to resume work and promised to expand the company's market value to more than US$50 billion within three to five years. After that, Ketuan Zhan began to contact employees by phone, trying to acquire the options in the hands of employees at a valuation of 4 billion US dollars.
Subsequently, Ketuan Zhan recalled Huawei's executives and issued a series of personnel appointments and removals. As of June 9, 2020, Ketuan Zhan has successively eliminated CFO Luyao Liu, and Wenguang Wang, the head of the mining center. Luyao Liu is responsible for controlling Bitmain's IPO plan. He also appointed Yanwu Ma as the HR director, Gang Ren as the head of the mining center, Yonggang Sun as the head of the supply chain, Ling Gu as the financial director, and Bin Zhu as the head of the mining machine business department. Bin Zhu is the senior executive of Huawei who was interviewed and left as mentioned in the previous article. During his tenure, he reduced Antminer’s 90% market share to 50%, and received a large number of complaints from miners. Internal employees once speculated that he might be Compete against the spies sent by the company.
In addition to recalling senior executives of Huawei, Ketuan Zhan also urged employees to return to work. They can receive a bonus of 10,000 yuan when they return to work on the same day, which is only half the next day. Ketuan Zhan showed a very kind side. Every time the elevator door is opened, Ketuan Zhan's hot gaze can be met, shaking hands, taking photos, and receiving money. As there is no personnel information, Ketuan Zhan does not know whether the person receiving the money is a Bitmain employee, and these people did not resume work the next day.
The effect of gentleness was not good, Ketuan Zhan began to force employees to return to work. Seeing that there are still very few respondents, Ketuan Zhan threatened employees through SMS, phone calls, EMS, emails and other harassment, issued multiple threats such as termination of contract, suspension of payment of social insurance, suspension of wages, and even used personal information saved by employees to form a group of employees. Domicile threats, requiring employees to perform "work handover", trying to force employees to return work computers, etc.
On June 10, 2020, the media revealed that Ketuan Zhan had controlled Bitmain's Shenzhen factory and prohibited employees from delivering normal shipments to paid customers, which caused difficulties in the operation of the Bitmain mining machine department.
On June 13, 2020, Hong Kong Bitmain, the parent company of Beijing Bitmain, issued a statement accusing Ketuan Zhan of signing a "Sales Agency Agreement" with the Ark Data Technology Co., Ltd. in which it holds shares, in an attempt to embezzle Beijing Bit's assets.
On June 17, 2020, the media revealed that Ketuan Zhan started selling 14,000 T17+ series mining machines at low prices.
On June 20, 2020, Hong Kong Bitmain officially suspended the supply of chips to the Shenzhen factory.
On July 13, 2020, in the "A Letter to All My colleagues in the Shenzhen Factory" released by Bitmain in Hong Kong, more details were added on the series of Ketuan Zhan's actions in June.
The legal person Feng Zhou of the Shenzhen plant is related to Ketuan Zhan. After being relieved of Ketuan Zhan's post, Jihan Wu flew to Shenzhen to have a long talk with Feng Zhou. Jihan Wu believes that Feng Zhou is the right person to manage the factory and help the company overcome difficulties, and decides to leave Feng Zhou to continue to manage the factory.
This wrong decision staged a story of a farmer and a snake. When Ketuan Zhan began to counterattack Bitmain, Feng Zhou was also quickly instigated and began to assist Ketuan Zhan in seizing customer machines and transferring 17,000 T17 mining machines in the warehouse. Hainan Continental Ark Data Technology Co., Ltd., which is held by Ketuan Zhan, sold them at a low price.
In order to protect the interests of customers, Jihan Wu had to make a compromise and paid the payment for some goods to a bank account controlled by Ketuan Zhan in exchange for delivery. However, after the other party received a payment of 109 million, the delivery stopped. On July 8, 2020, 5600 mining machines have been overdue.
At the same time, the factory defaulted on suppliers’ accounts payable as much as 200 million yuan. Bank acceptance bills issued by the factory, exceeding 36 million yuan, will expire on July 17, and more than 34 million yuan will expire on July 23. It is understood that Ketuan Zhan, after receiving the bank's dunning call, made it clear that he would not repay the loan, which would destroy the company and the entire group's credit in financial institutions.
7、 This is not the end
So far, the power struggle between the founders of Bitmain has been more than half a year. The office building already occupied by Ketuan Zhan is still empty, and most employees choose to work from home. Some chip developers returned to the office with the acquiescence of Jihan Wu and continued to maintain research and development to reduce the impact of infighting on technological iteration and competitiveness.
This giant ship that once stood on top of the supercomputer chip is crashing into the iceberg due to the madness of the former helm. Ketuan Zhan's madness and Jihan Wu's compromise made mistakes again and again. Bitmain tried to save himself many times, but was unable to get out of the black hole.
If the time goes back to that day in 2013, would Jihan Wu and Yuesheng Ge still choose to dial Ketuan Zhan?

Tarkov Overview - What is Escape from Tarkov?

Escape from Tarkov is a tactical, realistic, FPS with MMO elements developed by Battlestate Games. It is currently in closed Beta. The game features several maps in which your primary character, your PMC, goes into Raids in order to find and salvage loot and useful equipment to survive and thrive in Tarkov. Death is very punishing in Tarkov. If you die you lose everything you had on you when you die (with the exception of what's inside your Container and your melee weapon) including any equipment you brought with you or what you found inside the Raid.
Enemies can be players (PMCs) or Scavengers ('Scavs') that are either controlled by AI or by players. Unlike many shooters, AI enemies in Tarkov are deadly - they can and will kill you on sight. They have recently been upgraded to act more intelligently, shoot more accurately, and react to situations on the map, such as investigating noise of gunfire or searching. It features beautiful and immersive environments, intricate and in-depth weapon modification system, a complex health system, dynamic and specific loot placement, and multiple options for engagement. Do you want to play slow and stealthy, to avoid fights, or set up a deadly ambush on an unwary foe? Or do you prefer raw combat, where only your quick wit, placements of shots, and tenaciousness determines who gets out alive? It's your Tarkov. You make the rules.

An updated ammo chart can be found on the wiki.

Tarkov Wiki

Absolutely fantastic resource. You can visit them here.
It is a massive collection of everything that we players have been able to find.
They contain trades, user-created maps, lists of ammo, parts, weapons, loot, etc. If it's in the game, it's on the Wiki, somewhere.
I highly recommend opening the wiki page for the Map that you plan on raiding in.

Offline Raids - Player Practice

Offline raids is a feature added for testing and learning purposes for both new and veteran players alike. It is an incredibly useful tool.
In an offline raid, your progress is not saved. This means you don't keep anything you find, keep any experience 'earned' if you successfully extract, or lose any gear when/if you die. To access OFFLINE Raids, head into a Raid normally until you see this screen. Then Check the box indicating that you want to do an OFFLINE raid and you're good to go! You even have a choice on whether or not to add AI. You can also control how many AI enemies spawn, fewer than normal or a great deal more! You can even make Scavs fight each other. (Framerates beware.)
You can control how many scavs spawn (if any) as well as a number of other paramaters. New players should use offline raids as a tool to practice shooting, controls, movement, etc.

Tarkov's Maps

Tarkov features several maps - ranging from wide, beautiful vistas to ruined factory districts, to an abandoned laboratory where illegal experiments were being conducted. It is important to learn the maps you intend to play. In order to keep your gear, you must 'extract' at one of your designated exfiltration points. Not all extracts will be active every game, and some are conditional.

To see what extracts are available to you, double tap 'O' to show raid time and your exfils. If it has a ???? it might not be open.

Factory

Gate 3 Extract
A small, fast-paced map that was primarily created for PvP. Scavs spawn in all the time. Very close quarters, shotguns and SMGs tend to dominate here. PMCs can only access one Exit (Gate 3) without the Factory Exit Key. Good place to go if you need PMC kills as action is pretty much guaranteed. It is recommended NOT to bring in a lot of gear to Factory until you are experienced.
Factory Map in PvP is best played in Duos - due to the layout of the map, a Maximum of 6 PMCs may be present in the game. Due to the split spawn points, you effectively have 'sides' that have up to 3 spawn locations that are close together. This is why it is recommended to secure/scout enemy spawn locations. If you go in with a Duo, you at max have 2 players on your side for an even 2v2, and if played smartly you can eliminate them and know your 'side' is secure from aggression for the time being.
Upon loading in, scavs usually take a couple minutes to spawn, though this depends on the server in question and isn't super reliable. For new players, the best loadout in Factory is going to be a MP-153 Loadout - using just an MBSS (or similar bag) and ammo in your pocket to fight other players and Scavs. Scavs will often spawn with AKs and other 'vendorable' weapons, so is a good source of income.
Factory is also one of the best maps to Scav into, as Scavs can typically avoid the Exit camping strategy employed by a lot of weaker or newer players in order to secure gear, because they typically have extra exfiltrations whereas PMCs without the Factory Exit Key are stuck using Gate 3.
If you go in with a modicum of gear, it is recommended to keep at least a flashbang (Zarya) in your container. This will allow you to quickly slot it into an empty chest rig or pocket so you can throw it into the exit door, this will flash enemies and is cheap to do - the one time you survive because you flashed the 3 exit campers using shotguns will make this strategy extremely valuable.

Customs

Extract map
A fairly large map that was recently expanded and is expected to receive an overhaul within a patch or two, due to the choke point design of the map. Essentially, players spawn either on 'warehouse' or 'boiler (stacks)' side. If you see a large red warehouse ('big red') near you (Customs Warehouse), then you spawned on the warehouse side. If you don't, you likely spawned near Boiler side. Players can also spawn in several places in the woods North of boilers.
This map has the most quests in the game. Geared players often come to customs to challenge other squads over Dorm loot and to fight a Scav boss. New players are usually trying to do one of several early quests, such as ‘Debut’ which tasks them with killing 5 scavs on Customs and acquiring 2 MR-133 shotguns (pump shotties) from their corpses. Construction is also a popular hotspot as it has a lot of scav spawns as well as the location for the Bronze Pocketwatch, which is Prapor’s second quest.
Customs itself does not offer very much loot on average. There are several spots which can contain decent, but the vast majority is located in a couple different locations.
Dorms is the best loot location for Customs. It has two sets, 2 story and 3 story dorms. They each have their own sections of good loot, but the best is considered to be 3 story dorms, due to the presence of the Marked Room. The marked room requires a marked key to open, and has a good chance to spawn rare loot, such as keytools, documents cases, weapons cases, and high-end weapons. Due to the nature of the high value of this room, it’s almost always contested and it’s one of the best rooms in the game to farm, albeit with difficulty to successfully extract with the loot found. Note, though the key required has a maximum amount of uses, it is a fairly cheap key, and worth buying if you like to run customs and go to Dorms.
Dorms also has a ton of early quests (Operation Aquarius, for one) with some keys being valuable to use, but most dorms keys aren’t worth that much on the market. There’s too many to list here, but make sure to check the Map Keys and You at the top of the guide to determine what the value of a particular key is.
Checkpoint (Military Checkpoint) is also a decent loot spot, though not nearly as good as Dorms. If you have the key, it has a grenade box and 2 ammo boxes which can spawn good ammo. The jacket in the blue car also can spawn good medical keys as well as medical items. It is very close to the gas station, so I’ll include that here as well.
The Gas Station is one of the possible spawn locations for the scav boss. It has loose food items, a weapon box in the side room, with two keyed rooms leading to a safe and a med bag and box. Also contains a couple registers and food spawns on the floor. The emercom key can spawn on the seat in the ambulance out front.
North of the gas station is the Antenna, which contains 3 weapon boxes, a tool box, and a med bag. Possible location for scav boss spawn, albeit rarely, and also spawns regular scavs, like checkpoint and gas station.
Beyond that, there’s scattered loot around the map in different places, but usually not enough to warrant going out of your way for. There’s also scav caches, mostly around the middle road outside construction and around the boiler area.
The scav boss for customs is 'Reshala.’ He has 5 guards that have above-average gear and can be tough to deal with solo. The guards tend to be more aggressive than normal scavs, so they can be a lot to handle but are vulnerable to fragmentation grenades or flashbangs due to their close proximity to one another. Reshala himself has a good chance to have one or more bitcoin in his pockets, as well as his unique Golden TT, which is required for a Jaegar quest and used in conjunction with other Golden TT's to purchase a Tactec, good plate carrier. Reshala may spawn either Dorms (either bldg), New Gas Station, or rarely the tower north of the gas station. Scav bosses are dangerous enemies with escorts that have above-average loot (sometimes great loot) and are hostile to everyone, Including player scavs. Scav guards will approach a player scav and basically tell them to leave the area, and if they walk closer towards the scav boss they turn hostile.
The ‘official’ spawn rate for Reshala is 35%.

Woods

Woods Map with Exfil
A very large map that is mostly just a large forest, with the occasional bunker, and the Lumber Mill in the center. The Lumber Mill is the primary point of interest, as it contains a couple quest locations and is the primary location to farm Scavs, as Scavs killed on woods are a good source of end-game keys that are hard to find.
Since the map is so large and open, sniper rifles with scopes usually reign king here. You will see a lot of players with Mosin rifles as they are a cheap way to train the Sniper skill (for a quest later on) and are capable of killing geared players and scavs alike.
Overall, not usually very populated. An early quest from Prapor sends you here to kill a number of Scavs. A good map to learn the game, as although the loot is not fantastic, you can get experience with how the game runs and operates while fighting AI and possibly getting lucky with a key find off a scav.
As of .12, Woods now houses a Scav boss that acts as a Sniper scav. He is incredibly dangerous and usually carries a tricked-out SVDS. The 7.62x54 caliber is not to be underestimated. That caliber can and will wreck your shit through what most players are capable of wearing, especially early on in a wipe. He may also carry an AK-105, so he's going to be dangerous at both short and long ranges.
He has two guards, and he typically patrols the area around the Sawmill, and carries a key to a cache nearby full of goodies. His key is part of a quest for Jaegar.
Woods also has two bunkers, one of them being an extract and requiring a key. Both bunkers have some moderate loot in them, thus worth visiting, though not necessarily worth going out of your way for them. Several quests occur around the sawmill area, which contains a good couple keys that can spawn.

Shoreline

Shoreline Map, with Loot, Exfil, etc
A very large map, notorious for its FPS hit. Generally speaking, one of the better maps for loot. The primary point of interest is the Resort, but scavs spawn there, and is primarily occupied by hatchlings (players only with hatchet, ie melee weapon) and geared players. Resort has great loot, but requires keys to access most of it.
A great map to learn though from new players as the outskirts still contains plenty of loot and combat opportunities with AI scavs. You can hit Villa, Scav Island, Weather station, Docks, etc and come out with a backpack full of valuable gear fairly easily. The Village (Not to be confused with villa) contains a lot of toolboxes which can contain lots of parts used to upgrade your Hideout.
Location of many quests, including a large quest chain where players are required to kill many, many, scavs on Shoreline. For this and other reasons, probably the best map for new players to learn the game with.
A good loot route is to hit the village (caches in it), scav island (2 med bags, 2 toolboxes, 2 weapon boxes, 1 cache), burning gas station (weapon boxes and a safe), pier (potential extract, 2 pcs 2 safes and lots of filing cabinets), and weather station. Scavs may spawn around these areas, but most players just head straight for resort anyway, so you are much less likely to encounter them, especially if you avoid Mylta power (most players hit it on the way to or leaving from the resort). Excellent route as a player scav as well.

Interchange

Detailed map
Great, great loot area, but very complex map. Old computers might face unique struggles with this map. Features a mostly-binary exfil system like Shoreline, but.. kinda worse. Exfil camping is fairly common on this map, but usually avoidable. Huge map with multiple floors and many many different stores. Communication with teammates is a challenge on this map, but the map is also fantastically detailed.
This map features a lot of loot that depends on the kind of store you're in. It's a great place to farm rare barter materials which are valuable to sell on the Flea market or to use for quests or for hideout upgrades. An early quest (from Ragman) sends you here to kill a large amount of Scavs. I'd recommend getting Ragman to level 2 and accepting his quest asap when going to Interchange, as getting this quest done can take a while as it is and you want all scav kills to count towards progress.
Both the tech stores (Techlight, Techxo, Rasmussen) and department stores (Groshan, Idea, OLI) are the primary places to hit. There’s also Kiba (weapons store) as well as Emercom and Mantis. Players have different strategies, but this map is unique in the sense that it really rewards exploring. Most stores will have things you can grab that are worth quite a bit but are often overlooked. Very popular place to go in as a Player Scav.

Reserve

Brand new map, chock full of loot. Has more complex extracts than other maps, save for Labs. Excellent place to farm rare barter items, computer parts, and especially military hardware. PMCs have limited extracts, most being conditional, and the ones that aren’t require activation of ‘power’ to turn on the extract, which alerts the map the extract has been opened and can spawn Raiders (more on them below.)
Additionally, has a scav boss by the name of Glukhar, who has multiple heavily armed guards. He has multiple spawn locations and can arrive with the train.

The Lab ('Labs')

Here's a map.
DISCLAIMER: Labs, like much of Tarkov, is under constant development, so issues may be fixed or created without warning. Always check patch notes!
Labs is a very complex map compared to the rest of Tarkov. There is a great deal more exfiltrations but many of them have requirements or a sequence of events needed to be able to extract from them. It is recommended to read the Tarkov Wiki on Labs before raiding there.

LABS IS NOT LIKE OTHER MAPS. READ THIS SECTION CAREFULLY.

Labs is a lucrative end-game raid location, comparable to 'dungeons' in other games. They are populated by tougher enemies that give greater rewards. In order to go to labs, you need to acquire a keycard, this functions like mechanical keys but instead of opening a door, they unlock your ability to select Labs for a raid.
They may be found in-raid in various locations, most notably in scavs backpacks, pockets, and in filing cabinets. They may be purchased from Therapist at LL4 for 189K Roubles. Labs are populated by a unique kind of AI enemy, Raiders.

Raiders

Raiders are the Labs form of Scavs, or AI enemies. However, unlike other maps, they cannot contain player Scavs. Raiders have a much tougher than your average scav, they are capable of advanced tactics (such as flanking) and throw grenades and use other consumables as a player would. Once 'locked' onto you, they are typically capable of killing you very quickly, even if you are wearing high-end armor.
In Tarkov, Raiders act like the avatars of Death. They are clad in USEC and BEAR equipment, as they are effectively AI PMCs. Many changes have been made to labs and specifically how Raider AI works and to prevent exploits to easily farm them as well as bugs where they could be deadlier than intended.
A general rule of thumb is not to fight Raiders directly. They can and WILL kill you. Raiders can spawn with 7N9, or 'big boy' ammo. This ammunition type is incredibly lethal to players, even those wearing the toughest armor. If you get shot in the head, doesn't matter what kind of helmet, face shield, killa helmet, etc you are wearing, you will almost certainly die.
Because Raiders are controlled by AI, they have zero ping. They may also end to immediately respond as if you were aggressive even if they did not originally know you were there - ESP Raiders effectively will prone and return fire even as you ADS and put them in your sights.
This is why engaging a Raider must be done very, very carefully. There are a few strategies that you may employ, most commonly some form of baiting them towards an area and then killing them when they arrive. Players may accomplish this by generating noise - gunfire, melee weapon hitting walls, crates, etc, player deaths, players Mumbling (F1 by default) can all attract Raiders to investigate your area.
Due to the high power of Raiders, players often go in with minimal loadouts and seek to avoid conflict with other players, especially geared ones. Most players avoid PvP in Labs, though a good portion of the playerbase thoroughly enjoys hunting down poorly-geared players after they kill a few Raiders for them.
As such, players will lay prone in a hallway, or crouch in a room, and attract Raiders to enter their domicile by opening the door, and immediately headshotting them. Few Raiders actually wear helmets (though some do) so most players specialize in 'flesh ammo' or, ammunition that foregoes armor penetration in favor of raw damage in order to kill Raiders more reliably, because Raiders have slightly higher head health than PMCs do.
Raiders spawn with a great variety of equipment, weapons, armor, and materials such as medication or hideout parts. They tend to have chest armor and may have different helmets. Their pockets can contain Labs keycards, morphine, Ifaks, cash, and other items. They're always worth checking.
Raiders are a good source of grenades, they will often have F-1's and Zarya's in their rig or pockets that you can use to fight off players and Raiders alike.
Recently, changes have been made to Labs to make them less profitable so that other maps are more appealing. The cost and rarity of keycards increased, as well as reducing the frequency that raiders spawn, so that they come in more infrequent groups but also tighter in formation, while also lowering the overall output of individual Raiders, so that they are less likely to have a bunch of extra materials, such as grenades and other items.
Experience Farming on Labs
Labs is one of the best places to farm experience in the entire game. Killing a Raider with a headshot awards 1100 Experience. This does not include any looting, inspection (searching bodies), examine, streak, or other experience.
Killing a large sequence of Raiders gives additional bonus experience in the form of Streak rewards, usually 100 bonus exp per additional kill.
Surviving the raid multiplies all of these sources of experience by 1.5x
Changes coming to Labs
Disclaimer: I am not a BSG developer or employee. This is what I have seen on this subreddit and heard elsewhere. Some might be purely rumor, but other points are confirmed by Nikita Labs is undergoing constant changes. Nikita and BSG take feedback seriously, and always consider what the players are telling them. It known that Labs will eventually be accessed via the Streets of Tarkov map, and will require you to enter that map, make it to the labs entrance, and then extract from Labs to return to Streets of Tarkov and exfil from there as well. This will likely add an additional layer of risk to being ambushed for your goodies along your way out, as well as punishing damage taken in labs more severely. Additionally, keycards will have a limited number of uses, and may open more than one room.
The full extent of the changes coming is not known.
Remember, you can load a map in OFFLINE mode to practice against bots or to learn the map without fear of losing gear.

Tarkov's Health System

Tarkov Wiki Article
Tarkov has a very advanced health system, and while it might seem overwhelming at first, you'll get the hang of it rather quickly. It features a very wide variety of effects and injury, including hydration, energy, blood pressure, blood loss, fractures, contusion, intoxication, exhaustion, tremors and more.
Not all of the Health System is implemented yet. Expect changes!
Your character (PMC, or otherwise) has a combined Health of 435. Each of his limbs have separate health. Taking damage to a limb that reduces it to 0 'blacks' that limb. Blacked limbs are a problem. They greatly impair the activities your PMC performs, and taking damage in a blacked limb amplifies the damage by a multiplier and spreads that damage among your other non-black limbs equally. You cannot heal a blacked limb without the use of a Surgical Kit.
Notes: Bloodloss applies damage to the affected limb and can be spread like other damage to a blacked limb. Treat immediately. Also causes significant dehydration! Bloodloss also helps level your Vitality skill, which in turn gives you experience towards your Health skill, which is necessary to reach level 2 of in order to improve your hideout.
Losing a limb applies additional effects. Fractures also apply these effects but not the damage amplification (Except for damage if running on fractured leg.) Fractures require specialized medical kits to heal.
Dehydration is what happens when your Hydration level reaches 0. You can view your Hydration level in your gear page, at the bottom left. Becoming dehydrated is extremely bad. You take constant damage. Taking dehydration damage can kill you if you have a black chest or head. Restoring hydration helps train Metabolism, which improves positive effects from food and drink.
Head/Chest: Bullet damage resulting in losing your head or chest is instant death. Note: Bloodloss resulting in your Head/Chest being black does not result in death, but any damage to them beyond that point will! A back chest will causes you to cough (much like your stomach!)
Painkillers: Prevents coughing that comes from your chest. Doesn't help otherwise.
Stomach: Massively increased rate of dehydration and energy loss. You must find liquids or exit the Raid soon. Additionally, your PMC will cough sputter loudly, attracting attention. A black stomach multiplies damage taken by 1.5 and redistributes that damage across your entire health pool.
Painkillers: Significantly reduces the frequency and volume of the coughs.
Arms: Makes activities like searching, reloading, etc, take additional time, as well as adding a sway, reducing accuracy. Arms have a .7x damage multiplier.
Painkillers: Reduces sway, removes debuff Pain.
Legs: Blacked legs cause your PMC to stumble and be unable to run. Blacked legs have a 1x damage multiplier.
Painkillers: Allows you to walk at full speed and to run.
WARNING: Running while your legs are blacked or fractured WILL DAMAGE YOU.
Health Items
Tarkov features many health items - 'Aid' items, which can be used to restore your characters health and to fix ailments or injuries he receives as the result of combat or mishaps. The two most important health conditions to consider are bloodloss and fractures, which have both been covered above. Some food items may have ancillary effects, such as losing hydration.
Since in the current patch the only ailments to worry about are bleeding and fractures, it changes which health items are most necessary. We'll go over them below.

Health Restoration

Medical Items on Wiki
AI-2 medkit
The newb's medical kit. You receive several of these when you start Tarkov - they'll already be in your stash. Available from Level I Therapist, they are cheap and effective way of healing early in the game. They will not stop bloodloss. Because of this, you also need to bring bandages or a higher-grade medical kit. Affectionately called 'little cheeses' by the Tarkov community. Using it takes 2 seconds, and because of how cheap it is, it's often brought in by higher level players to supplement their healing without draining their main kit (which is capable of healing bloodloss or sometimes fractures). Due to its short use time, it's often very useful during combat as you can take cover and quickly recover damage taken to a vital limb. They're also useful as you can buy them from Therapist to heal yourself if you died in a raid.
Bandages
The newb's bloodloss solution. Available from Therapist at Level I. A better version, the Army Bandage is available at Level II, after a quest. Mostly obsolete after unlocking the Car Medical kit, but some players value them due to the Car's overall low health pool. Activating takes 4 seconds, and removes bloodloss to one limb.
Splint
The newb's solution to fractures. Cheap, takes five seconds to use, and takes up 1 slot. Fractures are much more common this patch, due to them being added back in the game from standard bullet wounds, not just drops. Available from Therapist at Level I, no quest needed. Can be used to craft a Salewa.
Alu Splint
More advanced form of the normal split. Works the same, but has up to 5 uses. Recommended to carry in your container if possible, due to frequency of fractures from gunfire.
CMS (Compact Medical Surgery) Kit
New medical item added in .12, fantastic item. Allows you to perform field surgery, removing the black limb state and allowing you to heal it beyond 0 hp. Takes 16 seconds to use, and cannot be cancelled so make sure you are safe if you are using it! Will reduce the maximum health of the limb it's used on by 40-55%, but will effectively remove all negative effects incurred by having a black limb. Highly recommended to carry in your container for emergencies. Can be bartered from Jaeger LL1, and purchased for roubles LL2.
Surv12 field surgical kit
Same as the compact surgical kit, but takes 4 seconds longer, and the health penalty is reduces to 10-20% max health of the limb. Considering this kit is 1x3, taking up a huge amount of space, it's probably not worth using. It's just too large. Better this than nothing, though.
Car Medical Kit
The newb's first real medical solution. Available LL1 as a barter (2 Duct Tape) and available for Roubles after completing Therapist's second quest. Has a larger health pool than AI-2's (220, vs AI-2's 100), and removes bloodloss. Takes up a 1x2 slot, so requires to be placed in a tactical rig in order to be used effectively. Cheap and fairly efficient, takes a standard 4 seconds to use. Rendered effectively obsolete when the Salewa is unlocked.
Often kept in a player's secure container as a backup health pool, before IFAKs are unlocked.
Salewa
Good medkit for use in mid and end-game. Contains 400 total health and can remove bloodloss. More rouble efficient form of a healing due to its high health pool, costs 13k roubles. Same size as the Car medical kit, so requires a tactical rig to use effectively. Because Tarkov does not currently have effects like Toxication in the game at the moment, this kit is favored by most players who go into a raid with at least a moderate level of gear. With a high health pool and relatively low cost, it's also a more efficient way of healing damage sustained while in raids. Unlocked at Therapist Level II after completing a level 10 Prapor quest, Postman Pat Part II. Required as part of Therapist's first quest, Shortage. This makes Salewas very valuable early on in a wipe as it gatekeeps the rest of Therapist's quests, most of which occur on Customs early on. Can be crafted in your meds station with a painkiller, splint, and bandage.
IFAK
Fantastic medical kit, and is the one preferred by most players. Features 300 health and the ability to remove bloodloss and a host of other negative effects that are not yet implemented into the game. It does not, however, remove fractures. Taking up only a single slot, it is favored by players in all stages of gear, and it is recommend to carry one in your Secure Container in case of emergencies. Is available at Therapist Level II for a barter (Sugar + Sodium), and may be purchased for Roubles at Level III after completing Healthcare Privacy, Part I. It is a fairly expensive kit, but due to its durability, its small size, and ability to remove bloodloss, it is a very common medical item used by players of all levels. Can be crafted in Lvl 2 medstation.
Grizzly
The 'big daddy' medical kit, boasting an impressive total health resource of 1800. It is also a very large kit, taking up 4 slots (2x2) - in order to be able to use this quickly, it would require specialized tactical rigs that feature a 2x2 slot. It removes all negative effects (some costing HP resource), including fractures. Used by highly-geared players who intend on staying in raids for an extended period of time, or by players with additional Secure Container space available in case of emergencies. It is available for barter at Therapist Level II, and purchase at Therapist Level 4. Due to its price point from Therapist at just under 23k Roubles and its healthpool of 1800, it is by far the most efficient method of healing from raid damage, at a 1.3 roubles per health, dramatically lower than other options available. Can be crafted in Lvl 3 medstation.

Pain Management

Using any of these items results in your character being 'On Painkillers' which allows you to sprint on fractured and blacked legs, as well as reducing effects of fractures and blacked limbs, and removing the debuff Pain. Essentially, the only difference between most of these items are the speed of use, price, availability, and duration of the effect. Note that the Hideout has changed how some of these items are used, and because Tarkov is under constant development, it is very likely that these materials may be used to create higher-grade medkits or to upgrade your medstation. That being the case, it's best to hoard the unknown items for now as efficiently as possible until you know you don't need them.
Analgin Painkillers
The holy grail of pain medication. "Painkillers" have 4 total uses. The total duration is greater than Morphine and less risk of waste. Takes a short time to use, and is available from Therapist Level 1 for both barter and Roubles. Makes a loud, distinctive gulping noise. Can be used to craft Salewa kits.
Morphine
Quick application of painkillers. Favored by some highly geared players as it has greater usability in combat then it's typical counterpart, Painkillers. Has a longer duration, but only one use. It is required for a fairly early Therapist (and a late Peacekeeper) Quest, so it is recommend to hoard 10 of them, then sell the rest unless you intend on using them. They are worth a good amount to Therapist and take up little space so they are a valuable loot item. Available from Therapist for Roubles at Level 4, after completing Healthcare Privacy, Part 3.
Augmentin
Basically a cheaper Morphine. One use, 205s. Not recommended over Painkillers due to its cost. No current barter for this item, so usually it's just a fairly expensive, small loot item. Most likely a component of a medstation manufacturing process or upgrade. Keep it.
Ibuprofen
Powerful painkiller. Lasts 500 seconds and has 12 uses. This item is recommended as your long-term solution for painkillers. While it is valuable because it's used to trade for THICC items case, it's the cheapest component and is very useful as a painkiller. It has a long duration and a large amount of uses, so keep it in your container for use as a painkiller if your primary painkillers wear off. Don't use it completely up, though. Keep the 1/12 bottles for the trade.
Vaseline
Powerful medical item. Cannot be purchased from dealers. Has a maximum of 10 uses. Removes Pain, applies Painkillers for 500 seconds (8.3 minutes). Useful to keep in your container as an alternative to Painkillers, though it takes 6 seconds to use, which is longer than other painkillers. Used as part of a barter trade for the Medcase.
Golden Star Balm
Fairly useful medical item. It can remove Pain and Contusion (not a big deal of a debuff, goes away on its own shortly) and provides a small bonus to hydration and energy. It also removes toxication and Radiation exposure, both of which are not yet implemented into the game. Like Vaseline, has a maximum of 10 uses. Painkiller effect lasts for 10 minutes, and takes 7 seconds to apply. Recommended to take only if you are going on large maps and you have extra room in your container. Can be used with Ibuprofen and 5x Med parts to craft 7 Propital.
