https://github.com/gridcoin-community/Gridcoin-Research/releases/tag/184.108.40.206 Finally! After over ten months of development and testing, "Fern" has arrived! This is a whopper. 240 pull requests merged. Essentially a complete rewrite that was started with the scraper (the "neural net" rewrite) in "Denise" has now been completed. Practically the ENTIRE Gridcoin specific codebase resting on top of the vanilla Bitcoin/Peercoin/Blackcoin vanilla PoS code has been rewritten. This removes the team requirement at last (see below), although there are many other important improvements besides that. Fern was a monumental undertaking. We had to encode all of the old rules active for the v10 block protocol in new code and ensure that the new code was 100% compatible. This had to be done in such a way as to clear out all of the old spaghetti and ring-fence it with tightly controlled class implementations. We then wrote an entirely new, simplified ruleset for research rewards and reengineered contracts (which includes beacon management, polls, and voting) using properly classed code. The fundamentals of Gridcoin with this release are now on a very sound and maintainable footing, and the developers believe the codebase as updated here will serve as the fundamental basis for Gridcoin's future roadmap. We have been testing this for MONTHS on testnet in various stages. The v10 (legacy) compatibility code has been running on testnet continuously as it was developed to ensure compatibility with existing nodes. During the last few months, we have done two private testnet forks and then the full public testnet testing for v11 code (the new protocol which is what Fern implements). The developers have also been running non-staking "sentinel" nodes on mainnet with this code to verify that the consensus rules are problem-free for the legacy compatibility code on the broader mainnet. We believe this amount of testing is going to result in a smooth rollout. Given the amount of changes in Fern, I am presenting TWO changelogs below. One is high level, which summarizes the most significant changes in the protocol. The second changelog is the detailed one in the usual format, and gives you an inkling of the size of this release.
Note that the protocol changes will not become active until we cross the hard-fork transition height to v11, which has been set at 2053000. Given current average block spacing, this should happen around October 4, about one month from now. Note that to get all of the beacons in the network on the new protocol, we are requiring ALL beacons to be validated. A two week (14 day) grace period is provided by the code, starting at the time of the transition height, for people currently holding a beacon to validate the beacon and prevent it from expiring. That means that EVERY CRUNCHER must advertise and validate their beacon AFTER the v11 transition (around Oct 4th) and BEFORE October 18th (or more precisely, 14 days from the actual date of the v11 transition). If you do not advertise and validate your beacon by this time, your beacon will expire and you will stop earning research rewards until you advertise and validate a new beacon. This process has been made much easier by a brand new beacon "wizard" that helps manage beacon advertisements and renewals. Once a beacon has been validated and is a v11 protocol beacon, the normal 180 day expiration rules apply. Note, however, that the 180 day expiration on research rewards has been removed with the Fern update. This means that while your beacon might expire after 180 days, your earned research rewards will be retained and can be claimed by advertising a beacon with the same CPID and going through the validation process again. In other words, you do not lose any earned research rewards if you do not stake a block within 180 days and keep your beacon up-to-date. The transition height is also when the team requirement will be relaxed for the network.
Besides the beacon wizard, there are a number of improvements to the GUI, including new UI transaction types (and icons) for staking the superblock, sidestake sends, beacon advertisement, voting, poll creation, and transactions with a message. The main screen has been revamped with a better summary section, and better status icons. Several changes under the hood have improved GUI performance. And finally, the diagnostics have been revamped.
The wallet sync speed has been DRASTICALLY improved. A decent machine with a good network connection should be able to sync the entire mainnet blockchain in less than 4 hours. A fast machine with a really fast network connection and a good SSD can do it in about 2.5 hours. One of our goals was to reduce or eliminate the reliance on snapshots for mainnet, and I think we have accomplished that goal with the new sync speed. We have also streamlined the in-memory structures for the blockchain which shaves some memory use. There are so many goodies here it is hard to summarize them all. I would like to thank all of the contributors to this release, but especially thank @cyrossignol, whose incredible contributions formed the backbone of this release. I would also like to pay special thanks to @barton2526, @caraka, and @Quezacoatl1, who tirelessly helped during the testing and polishing phase on testnet with testing and repeated builds for all architectures. The developers are proud to present this release to the community and we believe this represents the starting point for a true renaissance for Gridcoin!
Most significantly, nodes calculate research rewards directly from the magnitudes in EACH superblock between stakes instead of using a two- or three- point average based on a CPID's current magnitude and the magnitude for the CPID when it last staked. For those long-timers in the community, this has been referred to as "Superblock Windows," and was first done in proof-of-concept form by @denravonska.
Network magnitude unit pinned to a static value of 0.25
Max research reward allowed per block raised to 16384 GRC (from 12750 GRC)
New CPIDs begin accruing research rewards from the first superblock that contains the CPID instead of from the time of the beacon advertisement
500 GRC research reward limit for a CPID's first stake
6-month expiration for unclaimed rewards
10-block spacing requirement between research reward claims
Rolling 5-day payment-per-day limit
Legacy tolerances for floating-point error and time drift
The need to include a valid copy of a CPID's magnitude in a claim
10-block emission adjustment interval for the magnitude unit
One-time beacon activation requires that participants temporarily change their usernames to a verification code at one whitelisted BOINC project
Verification codes of pending beacons expire after 3 days
Self-service beacon removal
Burn fee for beacon advertisement increased from 0.00001 GRC to 0.5 GRC
Rain addresses derived from beacon keys instead of a default wallet address
Beacon expiration determined as of the current block instead of the previous block
The ability for developers to remove beacons
The ability to sign research reward claims with non-current but unexpired beacons
As a reminder:
Beacons expire after 6 months pass (180 days)
Beacons can be renewed after 5 months pass (150 days)
Renewed beacons must be signed with the same key as the original beacon
Magnitudes less than 1 include two fractional places
Magnitudes greater than or equal to 1 but less than 10 include one fractional place
A valid superblock must match a scraper convergence
Superblock popularity election mechanics
Yes/no/abstain and single-choice response types (no user-facing support yet)
To create a poll, a maximum of 250 UTXOs for a single address must add up to 100000 GRC. These are selected from the largest downwards.
Burn fee for creating polls scaled by the number of UTXOs claimed
50 GRC for a poll contract
0.001 GRC per claimed UTXO
Burn fee for casting votes scaled by the number of UTXOs claimed
0.01 GRC for a vote contract
0.01 GRC to claim magnitude
0.01 GRC per claimed address
0.001 GRC per claimed UTXO
Maximum length of a poll title: 80 characters
Maximum length of a poll question: 100 characters
Maximum length of a poll discussion website URL: 100 characters
Maximum number of poll choices: 20
Maximum length of a poll choice label: 100 characters
Magnitude, CPID count, and participant count poll weight types

Hi there, i've recently.started using wasabi, made a wallet and transfered some money without issue the first time I used it. Now I try to access my wallet to transfer some.bitcoin but I cannot seem to connect properly. It took a while but finally downloaded all filters, it connects to tor, backend and shows price of btc but can't seem to find any peers, log doesn't show any error for both tor nor general log afaik. I'm using linux mint (ubuntu) on its latest iteration and downloaded wasabi client from their domain 2 days ago so it should be updated, any ideas on what may be going on?
New England New England 6 States Songs: https://www.reddit.com/newengland/comments/er8wxd/new_england_6_states_songs/ NewEnglandcoin Symbol: NENG NewEnglandcoin is a clone of Bitcoin using scrypt as a proof-of-work algorithm with enhanced features to protect against 51% attack and decentralize on mining to allow diversified mining rigs across CPUs, GPUs, ASICs and Android phones. Mining Algorithm: Scrypt with RandomSpike. RandomSpike is 3rd generation of Dynamic Difficulty (DynDiff) algorithm on top of scrypt. 1 minute block targets base difficulty reset: every 1440 blocks subsidy halves in 2.1m blocks (~ 2 to 4 years) 84,000,000,000 total maximum NENG 20000 NENG per block Pre-mine: 1% - reserved for dev fund ICO: None RPCPort: 6376 Port: 6377 NewEnglandcoin has dogecoin like supply at 84 billion maximum NENG. This huge supply insures that NENG is suitable for retail transactions and daily use. The inflation schedule of NengEnglandcoin is actually identical to that of Litecoin. Bitcoin and Litecoin are already proven to be great long term store of value. The Litecoin-like NENG inflation schedule will make NewEnglandcoin ideal for long term investment appreciation as the supply is limited and capped at a fixed number Bitcoin Fork - Suitable for Home Hobbyists NewEnglandcoin core wallet continues to maintain version tag of "Satoshi v0.8.7.5" because NewEnglandcoin is very much an exact clone of bitcoin plus some mining feature changes with DynDiff algorithm. NewEnglandcoin is very suitable as lite version of bitcoin for educational purpose on desktop mining, full node running and bitcoin programming using bitcoin-json APIs. The NewEnglandcoin (NENG) mining algorithm original upgrade ideas were mainly designed for decentralization of mining rigs on scrypt, which is same algo as litecoin/dogecoin. The way it is going now is that NENG is very suitable for bitcoin/litecoin/dogecoin hobbyists who can not , will not spend huge money to run noisy ASIC/GPU mining equipments, but still want to mine NENG at home with quiet simple CPU/GPU or with a cheap ASIC like FutureBit Moonlander 2 USB or Apollo pod on solo mining setup to obtain very decent profitable results. NENG allows bitcoin litecoin hobbyists to experience full node running, solo mining, CPU/GPU/ASIC for a fun experience at home at cheap cost without breaking bank on equipment or electricity.

After yesterday's thread, I decided I wanted to run my own full node, partially to see how hard it was to do it, but more importantly to a) help myself validate my own transactions and b) help the network's decentralization. Well, I'm happy to say that it took less than an hour to get setup. I've used the script curl https://bitnodes.earn.com/install-full-node.sh | sh to get started. It literally takes care of 95% of the work, only thing missing is to adjust the settings in bitcoin.conf. Since I expected it would be much harder I decided to setup an Electrum Personal Server. It also took much much less than I expected, probably had it up and running 15 minutes from the moment I opened it's github page. I'm super happy to have my own node. It certainly isn't perfect since I'm using a VPS to run it, but I'll be getting a $50 Raspberry Pi and running it at home as soon as possible. If you have never looked into running a full node I very much encourage you to do it, it's SO much easier than people make it out to be and you'll be doing a great service to yourself and the network.
Make your own stakebox. Ultimate beginners guide how to compile any wallet on AARCH64 (Raspbery pi and other SBC)
I contemplated to wrote this for a long time, so it's finally time. As you know a lot of altcoins uses PoS (Proof-of-stake) way of "mining" coins. Which basically means, that you hold coins on your unlocked wallet and you are receiving stakes as a reward. This requires very little power and it can bring you a lot of rewards, at just 10W from the wall. So first I am using latest Raspbian on RPI4B 4GB in this example.Setting up Raspbian is not part of this process since it's very well documented. I recommend to change user from pi to something else due to security concerns and you can also do other stuff just search "security Raspberry PI" and you find a lot of articles, but this is not the focus of this guide. I know there are a lot of guides on the internet, but I am using like 5 sources, so it's compiled what other people wrote and some of my research. I am using AnyDesk insted of SSH or VNC server, because it works it's ligthweit and it just works. So after you see the gui of Raspbian, just launch terminal (CTRL + ALT + T) and do basic thing: sudo apt-get update && sudo apt-get upgrade Than press Y and let it run, after is finished, we need to prepare so dependency packages. Since most of the wallets using Berkeley DB 4.8 we need to obtain it. So in terminal wrote:
cd cd Downloads wget http://download.oracle.com/berkeley-db/db-4.8.30.NC.tar.gz tar -xzvf db-4.8.30.NC.tar.gz cd db-4.8.30.NC/build_unix ../dist/configure --enable-cxx make sudo make install
So wait unti it's finished and than you can delete files in Downloads folder in gui or use:
Watch the output folder which it creates, it's stated in the first two lines and copy then by highliting the text and CTRL+SHIFT+C copy it to your clipboard.
cd Streamies (this is that git created folder) ./autogen.sh ./configure CPPFLAGS="-I/uslocal/BerkeleyDB.4.8/include -O2" LDFLAGS="-L/uslocal/BerkeleyDB.4.8/lib" sudo make (this could take hours) sudo make install
And you are done, files is going to be in folder /uslocal/bin (DO NOT delete git created folder, because you are going to need it for faster compiling, when wallet get's and update.)
Now you can list files by:
And then you can copy/move them where ever you want by using:
sudo mv * [destination full path]
Let it run and go back to folder where you move those files.
sudo chmod +x streamies-qt (since we want to run wallet)
In most cases compiled files are going to in format of "shared library" so we need to create script to run it. Open up a text editor from gui or through nano. And paste this to that file:
And save it as a sh file, for example run.sh. Then we need to make it runnable so:
sudo chmod +x run.sh
Now to run it, it's just:
And here we are glorious GUI wallet appears and you are done, you can paste blockchain, wallet.dat from other sources, so this migration is pretty easy and you, if you have it on for exaple flash disk. So this is basic how to compile QT wallets on AARCH64. I am running 7 wallets, 2 of those are Masternodes and RPI 4B 4GB would handle way more, I am at best on half of my RAM. Some wallets need more package, but it's not much of and issue, since compiling stops and you just copy paste nape which is missing put it in the google and add "apt-get" after the name of package and you are going to see, what is the name of the packages so it can be retreived from package assinstant aka apt-get. So basically:
sudo apt-get install [package name]
Then press y and again wrote:
This process is going to continue where it was left off, so nothing is going to run from beginning. Updating wallets is basically exactly same, just repeat steps from "git clone" and after that proceed as it was written above. So I hope this helps some of you, to use this at home and not on some VPS, if you are anxious as me, to host my wallets on remote server.
having some issues with Electrum wallet on Ubuntu 20.04 LTS. i got it to install properly with no issues. but it seems like i am now have trouble connecting it to my node, below is what my .desktop file looks like # If you want Electrum to appear in a Linux app launcher ("start menu"), install this by doing: # sudo desktop-file-install electrum.desktop [Desktop Entry] Comment=Lightweight Bitcoin Client Exec=sh -c "PATH=\"\\$HOME/.local/bin:\\$PATH\"; electrum --oneserver --server localhost:50001:t %u" GenericName[en_US]=Bitcoin Wallet GenericName=Bitcoin Wallet Icon=electrum Name[en_US]=Electrum Bitcoin Wallet Name=Electrum Bitcoin Wallet Categories=Finance;Network; StartupNotify=true StartupWMClass=electrum Terminal=false Type=Application MimeType=x-scheme-handlebitcoin; Actions=Testnet; [Desktop Action Testnet] Exec=sh -c "PATH=\"\\$HOME/.local/bin:\\$PATH\"; electrum --testnet %u" Name=Testnet mode when opening up the wallet, i get the red dot on the bottom right hand corner, i can ping and access mynode via the local 192. address and i see electrum server is running. does it matter where the electrum.desktop file is located? as of right now i have it under /home/gp11/Downloads. is there anything else i can check? even if i remove electrum --oneserver --server localhost:50001:t i still get the same result with no connection, where i am thinking if i remove the line of code it should connect to other nodes. currently using myNode community Version 0.2.09 any help here would be appreciated - thanks in advance.
I have been trying to install Electrum 3.3.8 in Ubuntu 16.04 and ran into some issues with python etc. I opted out and just downloaded the app image , that seemed to work fine. I went ahead and deleted the app image and all folders to try and go back to install for Linux. please take a look at the screen shot and let me know how i can delete this Electrum Bitcoin Wallet shortcut which does execute anything. https://preview.redd.it/q04tfu3l3n151.png?width=1360&format=png&auto=webp&s=a3857c99f69fa8b58aeb39507d70611288406b70 Once i can delete this shortcut i will go back and try to install for Linux as appose to just the app image.
The abbreviated name of Tkey Messenger is tkey.me. First of all, TKEY-ME is a secure messenger with p2p audio and video calls, and in the future, a built-in digital wallet.
“Every day we communicate in messengers. We earn money at work. We make purchases and transfers. We are here to combine these processes in one application and make sending funds as easy as sending a message”
The Tkey Messenger as a new ecosystem
Do you think we are here to compete with other messengers? — No, there are a lot of great messengers. We are here to create our ecosystem and the internal market in it. Combine these processes in one application and make sending funds as easy as sending a message. After all, we work in the field of FINTECH, cryptography, and blockchain, why not apply the best practices and knowledge in practice? Therefore, the TKEY Messenger should be considered for a large ecosystem. This is a new payment segment that covers fast communication tools in combination with an internal payment system, a set of exchange practices, blockchain, cryptography, our own experience, and the experience of global companies.
You or your relatives live abroad and you want to send funds quickly, for example, 2600 USD — you just open a chat with your loved one, send a message and 2600 USD in the same second become available on your loved one’s account. https://preview.redd.it/nmz4ienrue651.png?width=697&format=png&auto=webp&s=c3902fc0df1ed2eba425c3f3db3eb8c40bc7a237 It turns out that you can exchange Tkeycoin for USD, EUR, or GBP in a matter of seconds, as well as instantly send them to any place in the world and without hidden fees, the exchange amount is immediately available on the screen. Or you have Bitcoin, and the Recipient needs dollars — Tkey Messenger will take care of all the complex tasks, you will only need to send a message to make the payment.
Each completed payment will be processed through adigital payment systemwithout Bank intervention. You can link your Bank card to automatically withdraw digital funds to your local currency.
“Moving money around the world should be as easy and cheap as sending a message. It doesn’t matter where you live, what you do, or how much you earn.”
Send TKEY or Bitcoin via message, has it become a reality?
In Tkey Messenger, you will be able to quickly send digital currency using a message. You can not specify a public address, but send a digital currency using a message.
Instantly send funds to friends or relatives anywhere in the world. No Bank, no problems, no hidden fees.
Top up your mobile phone or pay for the Internet?
The usual payments, such as the Internet or mobile payments, will certainly be available, because if we can transfer pounds from England to Canada in a matter of seconds, and the recipient will receive dollars, why can’t we make a payment for the Internet? “Of course you can.
What do we get in the future when using a Tkey Messenger?
We get an ideal payment system with instant transactions, fast access to various currencies, including digital, instant international payments, a huge platform for business, a marketplace with trusted sellers, secure transactions, while fast communication, p2p calls, and video communication. Not to mention various chips, in the format: cashback, savings account, invest. products, etc.
International transfers without Commission and in seconds;
Instant account opening — just create an account to get access to payments;
Access to funds 24/7/365 wherever you are.
Multi-currency wallet — you can use both digital currencies and classic currencies, such as the pound, euro, and dollar.
Payment in digital currency anywhere in the world.
The mobile Finance industry is developing rapidly against the backdrop of a growing number of Internet users and the increasing role of smartphones in modern life. Today, the mobile device market attracts about 2 billion people, who remain passive players in financial markets.
With the Tkey Messenger access, you always get access to instant Finance, shopping, and the nice things you want to get here and now. In practice, it has turned out that we can often forget the keys to the apartment, rather than the phone, so your finances will always be with you.
The Tkey Messenger version 1.0.0 is the core that opens up new features that we discussed above, payments, and more. Now it is a convenient and stylish messenger with an intuitive design, instant messaging, and secure audio and video communication.
The P2P audio and video calls in a Tkey Messenger
When creating the first version, we focused on high-quality video and audio communication. Now you can easily call by video and be sure that you will get a high-quality video stream, as well as the absence of restrictions from third parties because the connection is carried out on the principle of p2p.
Audio and video calls are made in p2p mode, so there is no recording of calls at all.
The web version of Tkey Messenger is available at → http://web.tkey.me/. The web version has full call functionality, so you can easily call through it, both via video and audio. Video calls are available with the “Share” function, you can easily “share” your screen for the interlocutor and show what is happening on it. This function can be used for presentations or training events.
Screen Sharing is a demonstration and broadcast of the screen. “Share” your screen for the interlocutor and show what is happening on it.
In the web version, you can launch a group video call. In the chat, tap the “handset” icon — the call will be sent to all participants in the chat, so all participants in the group chat can hold a video conference of up to 50 people. The user can turn on the camera and not turn it on, but simply participate in a video conference via audio.
On average, messengers that support the function of video calls in high quality, hold a video stream of no more than 8–10 people.In a Tkey Messenger, group conferences support up to 50 people. Soon-public online broadcasts and streams.
The first version only supports private chats and group chats. Group chats are also completely private, so there is no “Share” function, only the chat participant can invite another participant to the group chat.
Create your thematic chats. Work. Family. Friends. Be the first while we develop. Soon-public channels and chats.
Each participant, when they click the “Exit and delete” button, deletes messages and information from the chat on their side. In group chats, all information is deleted by the last person to leave the group chat. After deleting-all messages, media, photos, and other data that were in this chat are automatically deleted. If all participants leave the group chat, it will be automatically deleted, and all information published in the group chat will also be deleted.
The chat between the two parties
This is a classic private chat between two participants, instant messaging, sending media. The rights of the participants are equal. Any chat participant can delete the entire chat. after deleting all messages, media, photos, and other data that was in this chat, it is automatically deleted.
Our developers do everything to make Tkeycoin products as clear and convenient as possible for our users, so the process of using Tkey Messenger is very simple. If you want to install TKEY-ME on your laptop or computer, just download the installer from the official website and enjoy it.

Why is the Linux software repository frequently Brought up as one of the main benefits of using Linux when it’s so poorly maintained and you almost always end up getting software the same was as windows?
The fact that Linux has a repository of programs that are safe and easy to install is frequently mentioned as one of the main benefits over windows...But the repository gallery is awful apart from a small handful of software.... Example, I’m using Ubuntu, I go to get Netbeans IDE to work on some c++, well there’s two in the repository both with. 3/5 rating. 1.) is Apache netbeans, which DOSNT work. It won’t even open after being installed (see others with same results in comments)...2.) the second is just called netbeans, install it and suffer an array of issues making it unusable...(see many comments supporting this result)... Result -> have to go to the Apache netbeans website, find a older build (8.2) and download it from their website....exactly like in windows? Then have to use chmod x+ on the downloaded file to make it executable you then install...works perfectly Another example, Electrum bitcoin wallet, a super outdated version is in the repository.... full of comments screaming at you to NOT install/use this instead go to the official website and download it there... There’s a ton of examples just like these...in my experience very very few things in the repository are viable or worth getting/using...and for me those things are to add functionality that honesty shouldn’t need a download to add...such as gnome teaks and gnome nightlight(if Ubuntu already has a night light/redshift built in why the hell do I need another program to give slider functionality to the color change???) Lastly MOST software isn’t even in the repository. Broken and outdated or not. .. So really pretty much any program you want you have to go to that company’s website and download it and install it your self..just like windows but with more steps... So what the hell is even the point of the repository, why is it so poorly maintained, why does it not support more software that is already available for Linux and why the hell is it mentioned as one of the main benefits to using Linux over windows
Dear Groestlers, it goes without saying that 2020 has been a difficult time for millions of people worldwide. The groestlcoin team would like to take this opportunity to wish everyone our best to everyone coping with the direct and indirect effects of COVID-19. Let it bring out the best in us all and show that collectively, we can conquer anything. The centralised banks and our national governments are facing unprecedented times with interest rates worldwide dropping to record lows in places. Rest assured that this can only strengthen the fundamentals of all decentralised cryptocurrencies and the vision that was seeded with Satoshi's Bitcoin whitepaper over 10 years ago. Despite everything that has been thrown at us this year, the show must go on and the team will still progress and advance to continue the momentum that we have developed over the past 6 years. In addition to this, we'd like to remind you all that this is Groestlcoin's 6th Birthday release! In terms of price there have been some crazy highs and lows over the years (with highs of around $2.60 and lows of $0.000077!), but in terms of value– Groestlcoin just keeps getting more valuable! In these uncertain times, one thing remains clear – Groestlcoin will keep going and keep innovating regardless. On with what has been worked on and completed over the past few months.
UPDATED - Groestlcoin Core 2.18.2
This is a major release of Groestlcoin Core with many protocol level improvements and code optimizations, featuring the technical equivalent of Bitcoin v0.18.2 but with Groestlcoin-specific patches. On a general level, most of what is new is a new 'Groestlcoin-wallet' tool which is now distributed alongside Groestlcoin Core's other executables. NOTE: The 'Account' API has been removed from this version which was typically used in some tip bots. Please ensure you check the release notes from 2.17.2 for details on replacing this functionality.
Builds are now done through Gitian
Calls to getblocktemplate will fail if the segwit rule is not specified. Calling getblocktemplate without segwit specified is almost certainly a misconfiguration since doing so results in lower rewards for the miner. Failed calls will produce an error message describing how to enable the segwit rule.
A warning is printed if an unrecognized section name is used in the configuration file. Recognized sections are [test], [main], and [regtest].
Four new options are available for configuring the maximum number of messages that ZMQ will queue in memory (the "high water mark") before dropping additional messages. The default value is 1,000, the same as was used for previous releases.
The rpcallowip option can no longer be used to automatically listen on all network interfaces. Instead, the rpcbind parameter must be used to specify the IP addresses to listen on. Listening for RPC commands over a public network connection is insecure and should be disabled, so a warning is now printed if a user selects such a configuration. If you need to expose RPC in order to use a tool like Docker, ensure you only bind RPC to your localhost, e.g. docker run [...] -p 127.0.0.1:1441:1441 (this is an extra :1441 over the normal Docker port specification).
The rpcpassword option now causes a startup error if the password set in the configuration file contains a hash character (#), as it's ambiguous whether the hash character is meant for the password or as a comment.
The whitelistforcerelay option is used to relay transactions from whitelisted peers even when not accepted to the mempool. This option now defaults to being off, so that changes in policy and disconnect/ban behavior will not cause a node that is whitelisting another to be dropped by peers.
A new short about the JSON-RPC interface describes cases where the results of anRPC might contain inconsistencies between data sourced from differentsubsystems, such as wallet state and mempool state.
A new document introduces Groestlcoin Core's BIP174 interface, which is used to allow multiple programs to collaboratively work to create, sign, and broadcast new transactions. This is useful for offline (cold storage) wallets, multisig wallets, coinjoin implementations, and many other cases where two or more programs need to interact to generate a complete transaction.
The output script descriptor (https://github.com/groestlcoin/groestlcoin/blob/mastedoc/descriptors.md) documentation has been updated with information about new features in this still-developing language for describing the output scripts that a wallet or other program wants to receive notifications for, such as which addresses it wants to know received payments. The language is currently used in multiple new and updated RPCs described in these release notes and is expected to be adapted to other RPCs and to the underlying wallet structure.
A new --disable-bip70 option may be passed to ./configure to prevent Groestlcoin-Qt from being built with support for the BIP70 payment protocol or from linking libssl. As the payment protocol has exposed Groestlcoin Core to libssl vulnerabilities in the past, builders who don't need BIP70 support are encouraged to use this option to reduce their exposure to future vulnerabilities.
The minimum required version of Qt (when building the GUI) has been increased from 5.2 to 5.5.1 (the depends system provides 5.9.7)
getnodeaddresses returns peer addresses known to this node. It may be used to find nodes to connect to without using a DNS seeder.
listwalletdir returns a list of wallets in the wallet directory (either the default wallet directory or the directory configured bythe -walletdir parameter).
getrpcinfo returns runtime details of the RPC server. Currently, it returns an array of the currently active commands and how long they've been running.
deriveaddresses returns one or more addresses corresponding to an output descriptor.
getdescriptorinfo accepts a descriptor and returns information aboutit, including its computed checksum.
joinpsbts merges multiple distinct PSBTs into a single PSBT. The multiple PSBTs must have different inputs. The resulting PSBT will contain every input and output from all the PSBTs. Any signatures provided in any of the PSBTs will be dropped.
analyzepsbt examines a PSBT and provides information about what the PSBT contains and the next steps that need to be taken in order to complete the transaction. For each input of a PSBT, analyze psbt provides information about what information is missing for that input, including whether a UTXO needs to be provided, what pubkeys still need to be provided, which scripts need to be provided, and what signatures are still needed. Every input will also list which role is needed to complete that input, and analyzepsbt will also list the next role in general needed to complete the PSBT. analyzepsbt will also provide the estimated fee rate and estimated virtual size of the completed transaction if it has enough information to do so.
utxoupdatepsbt searches the set of Unspent Transaction Outputs (UTXOs) to find the outputs being spent by the partial transaction. PSBTs need to have the UTXOs being spent to be provided because the signing algorithm requires information from the UTXO being spent. For segwit inputs, only the UTXO itself is necessary. For non-segwit outputs, the entire previous transaction is needed so that signers can be sure that they are signing the correct thing. Unfortunately, because the UTXO set only contains UTXOs and not full transactions, utxoupdatepsbt will only add the UTXO for segwit inputs.
getpeerinfo now returns an additional minfeefilter field set to the peer's BIP133 fee filter. You can use this to detect that you have peers that are willing to accept transactions below the default minimum relay fee.
The mempool RPCs, such as getrawmempool with verbose=true, now return an additional "bip125-replaceable" value indicating whether thetransaction (or its unconfirmed ancestors) opts-in to asking nodes and miners to replace it with a higher-feerate transaction spending any of the same inputs.
settxfee previously silently ignored attempts to set the fee below the allowed minimums. It now prints a warning. The special value of"0" may still be used to request the minimum value.
getaddressinfo now provides an ischange field indicating whether the wallet used the address in a change output.
importmulti has been updated to support P2WSH, P2WPKH, P2SH-P2WPKH, and P2SH-P2WSH. Requests for P2WSH and P2SH-P2WSH accept an additional witnessscript parameter.
importmulti now returns an additional warnings field for each request with an array of strings explaining when fields are being ignored or are inconsistent, if there are any.
getaddressinfo now returns an additional solvable Boolean field when Groestlcoin Core knows enough about the address's scriptPubKey, optional redeemScript, and optional witnessScript for the wallet to be able to generate an unsigned input spending funds sent to that address.
The getaddressinfo, listunspent, and scantxoutset RPCs now return an additional desc field that contains an output descriptor containing all key paths and signing information for the address (except for the private key). The desc field is only returned for getaddressinfo and listunspent when the address is solvable.
importprivkey will preserve previously-set labels for addresses or public keys corresponding to the private key being imported. For example, if you imported a watch-only address with the label "coldwallet" in earlier releases of Groestlcoin Core, subsequently importing the private key would default to resetting the address's label to the default empty-string label (""). In this release, the previous label of "cold wallet" will be retained. If you optionally specify any label besides the default when calling importprivkey, the new label will be applied to the address.
getmininginfo now omits currentblockweight and currentblocktx when a block was never assembled via RPC on this node.
The getrawtransaction RPC & REST endpoints no longer check the unspent UTXO set for a transaction. The remaining behaviors are as follows:
If a blockhash is provided, check the corresponding block.
If no blockhash is provided, check the mempool.
If no blockhash is provided but txindex is enabled, also check txindex.
unloadwallet is now synchronous, meaning it will not return until the wallet is fully unloaded.
importmulti now supports importing of addresses from descriptors. A desc parameter can be provided instead of the "scriptPubKey" in are quest, as well as an optional range for ranged descriptors to specify the start and end of the range to import. Descriptors with key origin information imported through importmulti will have their key origin information stored in the wallet for use with creating PSBTs.
listunspent has been modified so that it also returns witnessScript, the witness script in the case of a P2WSH orP2SH-P2WSH output.
createwallet now has an optional blank argument that can be used to create a blank wallet. Blank wallets do not have any keys or HDseed. They cannot be opened in software older than 2.18.2. Once a blank wallet has a HD seed set (by using sethdseed) or private keys, scripts, addresses, and other watch only things have been imported, the wallet is no longer blank and can be opened in 2.17.2. Encrypting a blank wallet will also set a HD seed for it.
signrawtransaction is removed after being deprecated and hidden behind a special configuration option in version 2.17.2.
The 'account' API is removed after being deprecated in v2.17.2 The 'label' API was introduced in v2.17.2 as a replacement for accounts. See the release notes from v2.17.2 for a full description of the changes from the 'account' API to the 'label' API.
addwitnessaddress is removed after being deprecated in version 2.16.0.
generate is deprecated and will be fully removed in a subsequent major version. This RPC is only used for testing, but its implementation reached across multiple subsystems (wallet and mining), so it is being deprecated to simplify the wallet-node interface. Projects that are using generate for testing purposes should transition to using the generatetoaddress RPC, which does not require or use the wallet component. Calling generatetoaddress with an address returned by the getnewaddress RPC gives the same functionality as the old generate RPC. To continue using generate in this version, restart groestlcoind with the -deprecatedrpc=generate configuration option.
Be reminded that parts of the validateaddress command have been deprecated and moved to getaddressinfo. The following deprecated fields have moved to getaddressinfo: ismine, iswatchonly,script, hex, pubkeys, sigsrequired, pubkey, embedded,iscompressed, label, timestamp, hdkeypath, hdmasterkeyid.
The addresses field has been removed from the validateaddressand getaddressinfo RPC methods. This field was confusing since it referred to public keys using their P2PKH address. Clients should use the embedded.address field for P2SH or P2WSH wrapped addresses, and pubkeys for inspecting multisig participants.
A new /rest/blockhashbyheight/ endpoint is added for fetching the hash of the block in the current best blockchain based on its height (how many blocks it is after the Genesis Block).
A new Window menu is added alongside the existing File, Settings, and Help menus. Several items from the other menus that opened new windows have been moved to this new Window menu.
In the Send tab, the checkbox for "pay only the required fee" has been removed. Instead, the user can simply decrease the value in the Custom Fee rate field all the way down to the node's configured minimumrelay fee.
In the Overview tab, the watch-only balance will be the only balance shown if the wallet was created using the createwallet RPC and thedisable_private_keys parameter was set to true.
The launch-on-startup option is no longer available on macOS if compiled with macosx min version greater than 10.11 (useCXXFLAGS="-mmacosx-version-min=10.11" CFLAGS="-mmacosx-version-min=10.11" for setting the deployment sdkversion)
A new groestlcoin-wallet tool is now distributed alongside Groestlcoin Core's other executables. Without needing to use any RPCs, this tool can currently create a new wallet file or display some basic information about an existing wallet, such as whether the wallet is encrypted, whether it uses an HD seed, how many transactions it contains, and how many address book entries it has.
Since version 2.16.0, Groestlcoin Core's built-in wallet has defaulted to generating P2SH-wrapped segwit addresses when users want to receive payments. These addresses are backwards compatible with all widely used software. Starting with Groestlcoin Core 2.20.1 (expected about a year after 2.18.2), Groestlcoin Core will default to native segwitaddresses (bech32) that provide additional fee savings and other benefits. Currently, many wallets and services already support sending to bech32 addresses, and if the Groestlcoin Core project sees enough additional adoption, it will instead default to bech32 receiving addresses in Groestlcoin Core 2.19.1. P2SH-wrapped segwit addresses will continue to be provided if the user requests them in the GUI or by RPC, and anyone who doesn't want the update will be able to configure their default address type. (Similarly, pioneering users who want to change their default now may set the addresstype=bech32 configuration option in any Groestlcoin Core release from 2.16.0 up.)
BIP 61 reject messages are now deprecated. Reject messages have no use case on the P2P network and are only logged for debugging by most network nodes. Furthermore, they increase bandwidth and can be harmful for privacy and security. It has been possible to disable BIP 61 messages since v2.17.2 with the -enablebip61=0 option. BIP 61 messages will be disabled by default in a future version, before being removed entirely.
The submitblock RPC previously returned the reason a rejected block was invalid the first time it processed that block but returned a generic "duplicate" rejection message on subsequent occasions it processed the same block. It now always returns the fundamental reason for rejecting an invalid block and only returns "duplicate" for valid blocks it has already accepted.
A new submitheader RPC allows submitting block headers independently from their block. This is likely only useful for testing.
The signrawtransactionwithkey and signrawtransactionwithwallet RPCs have been modified so that they also optionally accept a witnessScript, the witness script in the case of a P2WSH orP2SH-P2WSH output. This is compatible with the change to listunspent.
For the walletprocesspsbt and walletcreatefundedpsbt RPCs, if thebip32derivs parameter is set to true but the key metadata for a public key has not been updated yet, then that key will have a derivation path as if it were just an independent key (i.e. no derivation path and its master fingerprint is itself).
The -usehd configuration option was removed in version 2.16.0 From that version onwards, all new wallets created are hierarchical deterministic wallets. This release makes specifying -usehd an invalid configuration option.
This release allows peers that your node automatically disconnected for misbehaviour (e.g. sending invalid data) to reconnect to your node if you have unused incoming connection slots. If your slots fill up, a misbehaving node will be disconnected to make room for nodes without a history of problems (unless the misbehaving node helps your node in some other way, such as by connecting to a part of the Internet from which you don't have many other peers). Previously, Groestlcoin Core banned the IP addresses of misbehaving peers for a period (default of 1 day); this was easily circumvented by attackers with multiple IP addresses. If you manually ban a peer, such as by using the setban RPC, all connections from that peer will still be rejected.
The key metadata will need to be upgraded the first time that the HDseed is available. For unencrypted wallets this will occur on wallet loading. For encrypted wallets this will occur the first time the wallet is unlocked.
Newly encrypted wallets will no longer require restarting the software. Instead such wallets will be completely unloaded and reloaded to achieve the same effect.
A sub-project of Bitcoin Core now provides Hardware Wallet Interaction (HWI) scripts that allow command-line users to use several popular hardware key management devices with Groestlcoin Core. See their project page for details.
This release changes the Random Number Generator (RNG) used from OpenSSL to Groestlcoin Core's own implementation, although entropy gathered by Groestlcoin Core is fed out to OpenSSL and then read back in when the program needs strong randomness. This moves Groestlcoin Core a little closer to no longer needing to depend on OpenSSL, a dependency that has caused security issues in the past. The new implementation gathers entropy from multiple sources, including from hardware supporting the rdseed CPU instruction.
On macOS, Groestlcoin Core now opts out of application CPU throttling ("app nap") during initial blockchain download, when catching up from over 100 blocks behind the current chain tip, or when reindexing chain data. This helps prevent these operations from taking an excessively long time because the operating system is attempting to conserve power.
How to Upgrade?
Windows If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), then run the installer. OSX If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), run the dmg and drag Groestlcoin Core to Applications. Ubuntu http://groestlcoin.org/forum/index.php?topic=441.0
ALL NEW - Groestlcoin Moonshine iOS/Android Wallet
Built with React Native, Moonshine utilizes Electrum-GRS's JSON-RPC methods to interact with the Groestlcoin network. GRS Moonshine's intended use is as a hot wallet. Meaning, your keys are only as safe as the device you install this wallet on. As with any hot wallet, please ensure that you keep only a small, responsible amount of Groestlcoin on it at any given time.
Groestlcoin Mainnet & Testnet supported
Multiple wallet support
Electrum - Support for both random and custom peers
Biometric + Pin authentication
Custom fee selection
Import mnemonic phrases via manual entry or scanning
BIP39 Passphrase functionality
Support for Segwit-compatible & legacy addresses in settings
Support individual private key sweeping
UTXO blacklisting - Accessible via the Transaction Detail view, this allows users to blacklist any utxo that they do not wish to include in their list of available utxo's when sending transactions. Blacklisting a utxo excludes its amount from the wallet's total balance.
Ability to Sign & Verify Messages
Support BitID for password-free authentication
Coin Control - This can be accessed from the Send Transaction view and basically allows users to select from a list of available UTXO's to include in their transaction.
HODL GRS connects directly to the Groestlcoin network using SPV mode and doesn't rely on servers that can be hacked or disabled. HODL GRS utilizes AES hardware encryption, app sandboxing, and the latest security features to protect users from malware, browser security holes, and even physical theft. Private keys are stored only in the secure enclave of the user's phone, inaccessible to anyone other than the user. Simplicity and ease-of-use is the core design principle of HODL GRS. A simple recovery phrase (which we call a Backup Recovery Key) is all that is needed to restore the user's wallet if they ever lose or replace their device. HODL GRS is deterministic, which means the user's balance and transaction history can be recovered just from the backup recovery key.
Simplified payment verification for fast mobile performance
Groestlcoin Seed Savior is a tool for recovering BIP39 seed phrases. This tool is meant to help users with recovering a slightly incorrect Groestlcoin mnemonic phrase (AKA backup or seed). You can enter an existing BIP39 mnemonic and get derived addresses in various formats. To find out if one of the suggested addresses is the right one, you can click on the suggested address to check the address' transaction history on a block explorer.
If a word is wrong, the tool will try to suggest the closest option.
If a word is missing or unknown, please type "?" instead and the tool will find all relevant options.
NOTE: NVidia GPU or any CPU only. AMD graphics cards will not work with this address generator. VanitySearch is a command-line Segwit-capable vanity Groestlcoin address generator. Add unique flair when you tell people to send Groestlcoin. Alternatively, VanitySearch can be used to generate random addresses offline. If you're tired of the random, cryptic addresses generated by regular groestlcoin clients, then VanitySearch is the right choice for you to create a more personalized address. VanitySearch is a groestlcoin address prefix finder. If you want to generate safe private keys, use the -s option to enter your passphrase which will be used for generating a base key as for BIP38 standard (VanitySearch.exe -s "My PassPhrase" FXPref). You can also use VanitySearch.exe -ps "My PassPhrase" which will add a crypto secure seed to your passphrase. VanitySearch may not compute a good grid size for your GPU, so try different values using -g option in order to get the best performances. If you want to use GPUs and CPUs together, you may have best performances by keeping one CPU core for handling GPU(s)/CPU exchanges (use -t option to set the number of CPU threads).
Fixed size arithmetic
Fast Modular Inversion (Delayed Right Shift 62 bits)
SecpK1 Fast modular multiplication (2 steps folding 512bits to 256bits using 64 bits digits)
Use some properties of elliptic curve to generate more keys
SSE Secure Hash Algorithm SHA256 and RIPEMD160 (CPU)
Groestlcoin EasyVanity 2020 is a windows app built from the ground-up and makes it easier than ever before to create your very own bespoke bech32 address(es) when whilst not connected to the internet. If you're tired of the random, cryptic bech32 addresses generated by regular Groestlcoin clients, then Groestlcoin EasyVanity2020 is the right choice for you to create a more personalised bech32 address. This 2020 version uses the new VanitySearch to generate not only legacy addresses (F prefix) but also Bech32 addresses (grs1 prefix).
Ability to continue finding keys after first one is found
Includes warning on start-up if connected to the internet
Ability to output keys to a text file (And shows button to open that directory)
Show and hide the private key with a simple toggle switch
Show full output of commands
Ability to choose between Processor (CPU) and Graphics Card (GPU) ( NVidia ONLY! )
Features both a Light and Dark Material Design-Style Themes
Free software - MIT. Anyone can audit the code.
Written in C# - The code is short, and easy to review.
Groestlcoin WPF is an alternative full node client with optional lightweight 'thin-client' mode based on WPF. Windows Presentation Foundation (WPF) is one of Microsoft's latest approaches to a GUI framework, used with the .NET framework. Its main advantages over the original Groestlcoin client include support for exporting blockchain.dat and including a lite wallet mode. This wallet was previously deprecated but has been brought back to life with modern standards.
Works via TOR or SOCKS5 proxy
Can use bootstrap.dat format as blockchain database
Import/Export blockchain to/from bootstrap.dat
Import wallet.dat from Groestlcoin-qt wallet
Export wallet to wallet.dat
Use both groestlcoin-wpf and groestlcoin-qt with the same addresses in parallel. When you send money from one program, the transaction will automatically be visible on the other wallet.
Rescan blockchain with a simple mouse click
Works as a full node and listens to port 1331 (listening port can be changed)
Fast Block verifying, parallel processing on multi-core CPUs
Mine Groestlcoins with your CPU by a simple mouse click
All private keys are kept encrypted on your local machine (or on a USB stick)
Lite - Has a lightweight "thin client" mode which does not require a new user to download the entire Groestlcoin chain and store it
Free and decentralised - Open Source under GNU license
Fixed Import/Export to wallet.dat
Rescan wallet option
Change wallet password option
Address type and Change type options through *.conf file
Import from bootstrap.dat - It is a flat, binary file containing Groestlcoin blockchain data, from the genesis block through a recent height. All versions automatically validate and import the file "grs.bootstrap.dat" in the GRS directory. Grs.bootstrap.dat is compatible with Qt wallet. GroestlCoin-Qt can load from it.
In Full mode file %APPDATA%\Groestlcoin-WPF\GRS\GRS.bootstrap.dat is full blockchain in standard bootstrap.dat format and can be used with other clients.
Groestlcoin Electrum Personal Server aims to make using Electrum Groestlcoin wallet more secure and more private. It makes it easy to connect your Electrum-GRS wallet to your own full node. It is an implementation of the Electrum-grs server protocol which fulfils the specific need of using the Electrum-grs wallet backed by a full node, but without the heavyweight server backend, for a single user. It allows the user to benefit from all Groestlcoin Core's resource-saving features like pruning, blocks only and disabled txindex. All Electrum-GRS's feature-richness like hardware wallet integration, multi-signature wallets, offline signing, seed recovery phrases, coin control and so on can still be used, but connected only to the user's own full node. Full node wallets are important in Groestlcoin because they are a big part of what makes the system be trust-less. No longer do people have to trust a financial institution like a bank or PayPal, they can run software on their own computers. If Groestlcoin is digital gold, then a full node wallet is your own personal goldsmith who checks for you that received payments are genuine. Full node wallets are also important for privacy. Using Electrum-GRS under default configuration requires it to send (hashes of) all your Groestlcoin addresses to some server. That server can then easily spy on your transactions. Full node wallets like Groestlcoin Electrum Personal Server would download the entire blockchain and scan it for the user's own addresses, and therefore don't reveal to anyone else which Groestlcoin addresses they are interested in. Groestlcoin Electrum Personal Server can also broadcast transactions through Tor which improves privacy by resisting traffic analysis for broadcasted transactions which can link the IP address of the user to the transaction. If enabled this would happen transparently whenever the user simply clicks "Send" on a transaction in Electrum-grs wallet. Note: Currently Groestlcoin Electrum Personal Server can only accept one connection at a time.
Use your own node
Uses less CPU and RAM than ElectrumX
Used intermittently rather than needing to be always-on
Doesn't require an index of every Groestlcoin address ever used like on ElectrumX
UPDATED – Android Wallet 7.38.1 - Main Net + Test Net
The app allows you to send and receive Groestlcoin on your device using QR codes and URI links. When using this app, please back up your wallet and email them to yourself! This will save your wallet in a password protected file. Then your coins can be retrieved even if you lose your phone.
Add confidence messages, helping users to understand the confidence state of their payments.
Handle edge case when restoring via an external app.
Count devices with a memory class of 128 MB as low ram.
Introduce dark mode on Android 10 devices.
Reduce memory usage of PIN-protected wallets.
Tapping on the app's version will reveal a checksum of the APK that was installed.
Fix issue with confirmation of transactions that empty your wallet.
Groestlcoin Sentinel is a great solution for anyone who wants the convenience and utility of a hot wallet for receiving payments directly into their cold storage (or hardware wallets). Sentinel accepts XPUB's, YPUB'S, ZPUB's and individual Groestlcoin address. Once added you will be able to view balances, view transactions, and (in the case of XPUB's, YPUB's and ZPUB's) deterministically generate addresses for that wallet. Groestlcoin Sentinel is a fork of Groestlcoin Samourai Wallet with all spending and transaction building code removed.

first time docker user. i need some help with setting up docker on wsl.
i followed u/nickjj_'s guide "Setting Up Docker for Windows and WSL to Work Flawlessly" up to the "Configure WSL to Connect to Docker for Windows" section where i learned that i also need to install docker on windows. yes, the article was clear and mentioned this at the beginning, but being the i am, i thought i could skip this and install docker as i did in a live ubuntu. so i went to docker hub, created an id and downloaded "docker desktop for windows" how should i now set up docker desktop for windows (220.127.116.11) to make it work with wsl? i have windows 10 home and installation failed because it seems it needs win 10 pro or enterprise version 15063 to run. any work arounds to make this work? i am trying to build an appimage for the electrum bitcoin wallet and one of the main developers suggested that i might be able to use docker on wsl.
Seriously frustrated that I STILL cannot claim my BCD. Without support from Coinomi or a downloadable QT, I am unable to do this. I don't know how to clone a github, use homebrew and make a Bitcoin Diamond QT client myself. I have a bunch of paper wallets and everything else has been claimed. Is there an easy guide to making a QT client that I can actually follow step by step? Or is there any other suggestions? I keep seeing that you can supposedly import a private key into Bither and then somehow use Bitpie to claim the BDiamond. I don't see how to export a seed phrase from Bither. Nor do I see how to import a private key into Bitpie. Very frustrating. Please help. SOS. Thanks so much. Project of the day... Get my freaking Bitcoin Diamond!!!
This is still alpha/experimental, so it is not completely user-friendly and there is not yet a lot of documentation, but it is usable. Note: I'm the lead developer (proof), feel free to ask me any questions
Rework of the Bitcoin fuzzer command line driver tool
Add stand alone cpu miner to the set of binaries (useful to showcase the new mining RPC calls, provides a template for development of mining pool software, and is valuable for regtest/testnet mining)
Cashlib: create a shared library to make creating wallets easier (experimental, this library factors useful functionality out of bitcoind into a separate shared library that is callable from higher level languages. Currently supports transaction signing, additional functionality TBD)
Improve QA machinery (travis mainly)
Port Hierarchical Deterministic wallet (BIP 32)
add space-efficient mining RPC calls that send only the block header, coinbase transaction, and merkle branch: getminingcandidate, submitminingsolution
To mine Bitcoin Rhodium you need to set up an XRC wallet and configure your miner of choice. You can choose between Web wallet, Electrum-XRC or Magnum wallet. To set up a web wallet please visit wallet.bitcoinrh.org. Or download and install Electrum-XRC wallet (recommended) for Windows, Linux and MacOS.
Any miner that supports X13 will be able to mine XRC. We have a few examples below of miners that are well tested with Bitcoin Rhodium network.
For any miner, configure the miner to point to:
(0–0.8 GH/s) stratum+tcp://poolcore.bitcoinrh.org:3061 (0.8–2 GH/s) stratum+tcp://poolcore.bitcoinrh.org:3062 (3–4 GH/s) stratum+tcp://poolcore.bitcoinrh.org:3063 (5+ GH/s) stratum+tcp://poolcore.bitcoinrh.org:3064 with your XRC address as username and x as password. You don’t need to open an account on pool. You will be mining to XRC address and mined coins will be transferred to your wallet • after blocks reach 10 block maturity • after you mined up minimal amount of coins (currently 0.1 XRC) • sometimes mined blocks could get rejected by network (orphaned) after they were counted as valid blocks. This is normal network behavior to follow longest chain
CCMiner is a GPU-based miner (NVIDIA) Command to run your CCMINER: ccminer-x64.exe -a x13 -o stratum+tcp://poolcore.bitcoinrh.org:3062 -O :without -D — show-diff
Settings: Url: (0–2 GH/s) stratum+tcp://poolcore.bitcoinrh.org:3062 (3–4 GH/s) stratum+tcp://poolcore.bitcoinrh.org:3063 (5+ GH/s) stratum+tcp://poolcore.bitcoinrh.org:3064 Algo: x13User: your XRC receiving address (make sure you set 2 distinct addresses for each hashing board) Pass: x Extranonce: leave off Priority set to 0 and 1 Once pool stratum address and your wallet as user are set up you should see your miner mining against XRC pool. When miner is working the status column is green. The pool and miner are incorrectly configured now as status says “Dead” highlighted in red.
Instructions for mining XRC on BSOD pool
Pool link:bsod.pw/en/pool/dashboard/XRC/ Use this code for your miner: -a x13 -o stratum+tcp://pool.bsod.pw:2582 -u WALLET.rig BSOD pool allows both solo and party mining.
For solo mining use code: -a x13 -o stratum+tcp://pool.bsod.pw:2582 -u WALLET.rig -p m=solo And for party mining use: -a x13 -o stratum+tcp://pool.bsod.pw:2582 -u WALLET.rig -p m=party.yourpassword
NOTICE: You can use us for North America and asia for Asia instead of euin your .bat file or config. You can also use BSOD pool’s monitor app forAndroidandiOS.
Instructions for mining XRC on ZERGPOOL
Zergpool offers low fees (just 0.5%) and also SOLO and PARTY mining with no extra fees. To mine XRC on Zergpool use this command lines for your miner:
Regular: -a x13 -o stratum+tcp://x13.mine.zergpool.com:3633 -u -p c=XRC,mc=XRC Solo: -a x13 -o stratum+tcp://x13.mine.zergpool.com:3633 -u -p c=XRC,mc=XRC,m=solo Party: -a x13 -o stratum+tcp://x13.mine.zergpool.com:3633 -u -p c=XRC,mc=XRC,m=party
Use your coin wallet address as username in mining software. Specify c=SYMBOL as password to identify payout wallet coin, and the same coin in mc=SYMBOL to specify mining coin. For more information and support please visit http://zergpool.com Notice that when there are more pools mining XRC in different geographic/availability locations choose the nearest to you as lowest priority and then add desirable fall back pool options in different geographic locations or pools. This is useful when one pool experiences issues, to fall back to different pool in Bitcoin Rhodium network.
