Bitcoin mentioned around Reddit: Best gpu for mining bitcoin+gaming (except gtx 1080ti prob looking for other brands cause I’m GeForce gpu user and idk anything abt amd’s side) tks /r/buildapc
Ok, A little backround. I know hardware and networking. I can build just about any config of a computer. I understand overclocking and undervolting. I can invest around 2,700 for initial investment. So do I buy hardware to build a GPU miner with at least 6 cards or more? Probably RX580 as they are cheap and I have one in my rig. More on that later. Or do I a Asic miner like this I understand a GPU miner is multiple coins and not Bitcoin, and Asic is nothing but Bitcoin. I've done the math on the Asic miner and the ROI in about 3 months with a net gain of about ~10,000 USD a year @ .13 cents per Watt. I've had a hard time finding a solid or semi way of calculating the earnings for a GPU miner. Not only because it is many coins or dedicated to one coin, but there our other variables involved. However I have more control of the hardware if it fails. I dipped my toe into mining with my own rig that has a RX580 fatboy and a AMD Phenom ii x4 955 black edition. I overclocked the GPU and undervolted the CPU to reduce heat since it was hitting 62 cel. The GPU gets 12.5 sol/s and the CPU was getting ~322 h/s. All this added up to ~170 watts and a net of .00218322 BTC/Month. This was all done using Cudo as it was easy to find and setup just to test. This was just a test to see how it would work. I wouldn't use Cudo to full scale as it is a pool and the transfer to a Wallet is pretty steep in relationship to earns. I understand that in a pool you get your share based upon how much of the "work" you did to get find block. So do I build or buy? With that much computation power do I need to join a pool? What software is best for pool or alone? I am comfortable with CLI as long as it's well documented, but would like a remote GUI. Also what is the best wallet with the best fees for transactions. Currently using uphold since I use Brave. I think I covered as much as I could, if you have any questions let me know. Any advice would be great. If I should post this else where let me know please or I could just cross post it. TIA. Be safe, stay safe! Edit: Words and BTC earning was WAY off then I first typed this.
Is worth start mining with the actual situation of the cryptocurrency market?
I've been watching the market for over 3 years now. For those years I've been a student with no money to invest, and now that I'm almost out of the university and I have some money I wanna finally start on this world. For some weeks now I've been working on a planning for building a 6 GPU mining rig, all theoretical earnings calculated with NiceHash & WhatToMine. The actual theoretical profits for this one are like 250 EU month (1.40€/day per GPU) with AMD RX 5700 , having an electricity cost of o.o79EUkWH. I've compared all the actual GPUs on the market, and that's the best one I could find in terms of ROI (I start to get profits after 1 year and 1 month). I've seen some posts talking about much better profits & less ROIs but I couldn't find a better profit for a GPU rig, maybe I'm doing something wrong! To see if the theoretical numbers are right I tested them with an RTX 2060 on my own personal computer and I had a profit of 1.20 EUR /day when the theoretical profit for that GPU was about 0.80 EUR /day. So, after all those weeks comparing, thinking about a long term Investment plan and searching for LOTS of information i conclude that it's worth spending a total of 3000 EUR into mining. Now I wanna ask you guys, with the actual situation of bitcoin (going up and up) and the difficulty raising over time...is it worth investing all that money on GPU mining right now? I'm afraid about investing the money and start to see a massive decrease in my profits, either for bitcoin going down or the difficulty going up nonstop. Also, I've not exposed all my plan, but doing it this way (mining with NiceHash and with 6 AMD RX 5700) is a nice plan or there is something with better profitability/ ROI? Maybe mining myself small cryptos and then exchange them to bitcoin, etc... All knowledge is welcomed. Btw, I'm a computer science engineer, that's why I wanna start on mining instead of trading stocks, because I know how computers work and I think that my knowledge on Pc & GPUs could help me on doing this efficiently. And sorry for my "not so good English", it's my 3rd language! Thanks all. EDIT: I could also buy the GPUs & equipment for the rig on a 2nd hand market, which would totally lower the total price of the rig, reaching ROI faster and if something goes not as expected, have less losses. Ofc buying at a 2nd hand is somehow risky but maybe worthy!
Building an Ethereum Mining Rig (13 GPU) - 4th part
Third update to the guide "Building a Mining Rig for Ethereum". The absolute first guide to building a RX Vega 64 8gb 13 GPU Mining Rig. Reading this guide to building a 13 GPU Ethereum mining rig requires adequate knowledge of building and running an Ethereum Mining Rig. We therefore recommend a previous view of our Guide to build a Mining Rig and related updates. Let's immediately list the hardware used: - Asus Mining Master X370 mainboard - Core i5 Coffee Lake CPU - 480 or 500GB SSD - 32Gb Ram - 13 GPU RX Vega 64 8Gb - 3 x 1000W power supplies - 1 1200W power supply - 8Gb USB stick In this guide we will obviously not explain how to mount the hardware of a Rig. The only notes we wish to underline are the following: - the 1200W power supply must be the primary one on which to connect 4 GPUs and the video output for the monitor - all the risers, as well as obviously the GPUs, must be powered through the 8-pole connections of the power supplies. We strongly advise against the use of 6-pole ports. Therefore, have the appropriate number of cables available for all connections. Risers can also be powered in pairs. - the model of the video card used is the Asus Rog Strixx Gaming RX Vega 64 8Gb The operating system is Windows 10 updated to the latest version available. The tool for creating installation media is available at the following link https://www.microsoft.com/it-it/software-download/windows10 to be able to use the USB key as a launcher for installing Windows 10 . With the Asus Mining Master, the GPU risers can be connected directly to the motherboard via the USB cable, thus making one of the small components of the riser kits unusable. After making all the connections on the motherboard, check that all GPUs are highlighted in green when the PC starts up. If not, move the USB cable on the motherboard one position. It may take at least 2 or 3 attempts. Ethereum mining with 13 GPUs Having solved this possible small inconvenience, let's proceed with the installation of the AMD Adrenaline 2020 drivers, always updated to the latest version, relating to the RX Vega Series. If you want to proceed with more caution, the advice is to disconnect all the GPUs (remembering the locations of the USB cables) except one before installing the drivers. The mining will be carried out on the Ethermine pool, our favorite, using the Claymore 15 software. Once the download is complete, you will have to unzip the folder on the desktop and open the start.bat file contained in the Claymore folder using Notepad. The procedure is the usual one: delete the content and copy-paste the following command string: start config.dll -epool eu1.ethermine.org:14444 -ewal "your ETH wallet address" -epsw x -worker "worker" EthDcrMiner64.exe Where EthDcrMiner64.exe is the executable, -epool indicates the pool to mine and its port, -ewal is the wallet address and -epsw is the password that we leave blank (X). In place of "your wallet address" you will have to put your Ethererum wallet and instead of worker you will enter an identification number in case you plan to build more RIGs (such as RIG1, RIG2, etc ...). At the following link, many other useful commands for your Rig: https://github.com/Claymore-Dual/Claymore-Dual-Miner Try to run mining and check that the system is stable. In the Payouts section, after a few minutes of mining, you can decide the minimum amount of Ether to be sent to your wallet by simply entering the IP address of the RIG. We performed the mining directly on the Ethereum address of the Exodus wallet. Coinbase is not supported. Overclocking with OverdriveNTool Let's proceed now with the download of OverdrivenTool at the following link: https://forums.guru3d.com/threads/overdriventool-tool-for-amd-gpus.416116/ For those unfamiliar with it, we recommend reading our software guide. For those who do not intend to experiment or do not completely trust their software experience, at the following link you can view the settings on the parameters of the GPUs and the RAM of the GPUs - and other small tricks - to obtain the best possible performance without forcing the cards too much. video. On our Youtube channel (subscribe numerous !!!) you will now be able to see the video relating to the start of mining and the one concerning the stabilization phase. To better cool the Rig we have also installed fans for the extraction of heat as caution is never too much. Moreover, there is also an aesthetic gain. Conclusions on the guide to build a 13 gpu ethereum mining rig. Finally, we conclude this guide by reporting what everyone was waiting for (we do not say how long we had to wait before obtaining this result) the video link complhttps: //www.youtube.com/watch? V = k53XZn3zc9I & t = 61seto del Rig e del Mining . We remain available for any advice, both on pools, on yield and on consumption.

We present the complete guide to overclocking GPUs with OverdriveNTool for your Ethereum Mining Rig! In this special we will write a complete guide to OverdriveNTool, in our opinion the most efficient, fast and immediate software for overclocking GPUs dedicated to mining. The interface is presented in a very simple and no-frills way, as if to suggest how much the program was created to go directly to the purpose. We remind you that after installing the drivers (see our guide to build a 6 GPU Ethereum Mining Rig) you will need to go through the Radeon Settings (Radeon Settings), select Game, Global Settings and for each GPU in your mining rig (or mining rig) you will need to make sure that HBCC memory is disabled. Do the same with the Crossfire option, checking that it is also disabled. Reboot the system and verify that all video cards have indeed not enabled HBCC and Crossfire before proceeding. At the following link the software download and technical specifications: https://forums.guru3d.com/threads/overdriventool-tool-for-amd-gpus.416116/ Recall that the GPUs in Atiflash will numerically correspond to the GPUs in ONT and Claymore, without misalignment. First we open our BIOS previously modified with Bios Polaris or, possibly, a stable Bios Mod downloaded from specialized sites such as Anorak via ONT. However, we can also overclock the original Bios of the GPU. Follow the OverdriveNTool guide carefully when operating at these levels! Click on New to create a new profile for the selected GPU. At first you will find yourself on the 0 which will correspond to the 0 in Atiflash and Claymore. I repeat once again: identical GPUs can behave differently; for this reason, the most stable final overclocking may vary from card to card. It will be sufficient to load the first profile on each subsequent tab, select New, make the necessary changes and save it with a different name (possibly recognizable, such as GPU1-OC Memory or GPU2-Temp, etc ...). The stages of the GPU and Ram. On the left we find the stages or clocks of the GPU with relative voltage for each sector. Some users disable the first 6 stages (from P1 to P6) to ensure that once the command for the minion is executed, the GPU immediately goes to the last stage. For those who, like us, restart the RIG once every 2 or 3 days, or even more, it is an unnecessary procedure. We recommend, at least for the first tests, to leave them activated. Once you have reached the limit of the video card, you can check whether disabling them will bring some improvement in terms of hashing on the screen without the pool being affected. Because in effect our goal is to have a high hash-rate and with a minimum percentage of errors on the pool even at the expense of a lower hash-rate in our RIG. In the central part we find the speed of the memory divided into 3 sectors. We will operate directly on the latter. On the right you can see the speed of the fans, the temperature that the fans must maintain (in our bios-mode it is set at 75 ° to which we obviously never arrived), the acoustic limit (in a RIG it is a parameter to always keep consideration). The last section at the bottom right, the Power, is divided into the maximum reachable temperature (with our Pulse set at 84 ° while with the XFX at 75 °) and the Power Target, strictly linked to the modified Bios that we are overclocking . You can try at the end of all tests, in the event of instability of one or more GPUs, to give less power starting from -25%. In this guide we will refer to the XFX RX 580 8GB GDDR5, with GPU clock at 1200Mhz and Memory at 2150Mhz. 8 video cards theoretically identical in total. Let's put into practice what has been written up to now ... We immediately opted for blocking the stages by operating directly on the latter for both the GPU Clock and the RAM. From these levels it starts to drop with the voltage of both the GPU and the RAM, alternatively always checking hashing, consumption and the stability of the system (usually 5-10 minutes are enough). When the voltage is too low, the GPU will not start undermining. The goal is to obtain the best performance / consumption ratio, always parameterizing the results obtained on the pool. A very high hashrate or very low consumption can often create numerous errors in the mining phase. With 8 RX580 8GB video cards we reached a total consumption (thus including all the components of the RIG) of 770 Watts for an average of less than 100 Watts per GPU. The result was achieved by bringing the GPU clock voltage to 1000 and the RAM to 900. Lower values are theoretically possible but could cause system instability. As mentioned previously, each video card is different from the others and on one of the eight GPUs we were forced to lower the power by 25%. After these tweaks, we got results on the pool with a hashrate often higher than 240mhs. We would like to emphasize that GPU overclocking is the absolute operation that will take you the longest time. It can take hours to reach the so-called "sweet spot" of each video card. Our OverdriveNTool guide will surely help you! But this achievement will give you great satisfaction, we guarantee it. Below the stable settings for the RX Vega 64 video cards of our 13 GPU Mining Rig of which you can see some videos on our YouTube channel: https://www.youtube.com/channel/UCdE9TTHAOtyKxy59rALSprA Complete Guide to OverdriveNTool See you soon for the next guide dedicated to mining!

New builder looking for some general advice, as well as a few specific points
I am completely new to all of this, but I felt like this quarantine season would be a good a time as any to try this out. Today I read a lot of articles and picked out parts from pcpartpicker with little clue of what I was doing. I just got components that seemed to be highly rated and decently priced. My intentions for this computer is a solid computer that is nice and I can use for a decent number of years. Nothing crazy like mining bitcoin, just general use and gaming. My general price cap is around $1500, but if its worth enough to go over, I can do a smidgeon more. For a little context, this would be the first PC I owned, so setting up ethernet-related stuff is completely foreign to me. AAAAAANNNYYYways, I have a couple questions for people who are more familiar with builds.
Can one of you lovely people take a look at my parts list and give me a heads up if I'm missing anything major or made some rookie mistake (Besides a keyboard/mouse). The compatibility notes said that I might need a fan mounting adapter; is there somewhere I could find those and how would I know if it is compatible? Or should I just find another fan?
What do I need to set up an ethernet connection besides a wall and an RJ45 cable? Like, what do I connect the cable to in the PC?
Is my computer underpowered/overpowered for what I want it to do? My biggest thing is being able to run games and such smoothly with good FPS and graphics.
Am I allocating my budget well? Like, should I be paying more for my GPU and less for my power supply? Is there some resource/rule of thumb for how expensive each part should be proportional to the others?
**Disclaimer** [Still testing, and Tuning but the new AMD RDNA Architecture is new and not only is AMD still optimizing drivers, the mining Developers who DO NOT get GPU's sent to them, are still working on optimizations. Please be patient with me as I continue to test and allow sufficient time for new miners to be developed.] Same as before, I am sharing my performance numbers with the Crypto Mining community, so we can collaborate together. The RX 5000 series GPUs, unfortunately, don't have the ability to mine every Algorithm available. Mining Devs are still working on it still, but you find what I tested so far below. I did test the SoftPowerPlayTables, MorePowerTool and force flashing a different Vbios on the GPU but to no avail. The card either won't boot or if it does it looks the core clock to 300 Mhz. These GPU's were meant to compete against the GTX 1660 TI and 1660 Super, but due to price war with Nvidia, AMD released a VBIOS to allow the RX 5600 XT compete with the RTX 2060 (KO). I will test any updates, and when I get time, I will update my findings below. I did a live stream recently, which you can find below, but it was lengthy. I speak on the recent AMD launch of this GPU, what I tried, the mining performance, power draw, and whether you should consider this GPU for cryptocurrency mining. So if you got time, please feel free to check it out, otherwise, when I get time from my busy life, I will try to get a summary video together for you guys. Carter from BitsBeTrippin should be doing his own independent testing in the future, and I always recommend checking more than one review for your research. Take care! Sapphire Pulse RX 5600 XT | AMD Adrenalin 2020 Edition 20.1.3
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.

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.
Features
Groestlcoin Mainnet & Testnet supported
Bech32 support
Multiple wallet support
Electrum - Support for both random and custom peers
Encrypted storage
Biometric + Pin authentication
Custom fee selection
Import mnemonic phrases via manual entry or scanning
RBF functionality
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.
Features
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.
Features
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).
Features
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).
Features
Ability to continue finding keys after first one is found
Includes warning on start-up if connected to the internet

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.
Features
Use your own node
Tor support
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.
Changes
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.
ASICs are coming to the Ethereum mining industry, and small independent miners are virtually doomed. 2Ether has come up with a solution — the third element in our dynamic block reward system. But before we explain it, we’ll have to talk about Ethereum ASICs. If you don’t know that much about Ethereum, you might be surprised to learn that ASICs for mining ETH actually exist. Isn’t Ethereum’s algorithm — Ethash — supposed to be ASIC-resistant? If it isn’t then why is everyone still mining using GPUs? Well, Ethash is indeed much less ASIC-friendly than the algorithm of Bitcoin. It doesn’t mean that you can’t make ASIC chips for mining ether, though. It’s just that it’s difficult to make ASICs that would be much more efficient than graphic cards (GPUs). The efficiency of a piece of mining hardware is calculated as a ratio of power (measured in kilowatt hours) to hash power (measured in megahash per second). So for example, if you have two devices that both produce 50 MH/s, but one of them consumes 1 kWh, and the other consumes 2 kWh, then the first device is twice more efficient. ASICs cost a lot of money to design, and their market price is high. So it only makes sense to buy an ASIC if it gives you a serious advantage over other types of hardware. You should also keep in mind that if the algorithm changes, you’ll need to replace your ASIC with a new model. Such chips are built to carry out one task and one task only — that’s why they are called application-specific integrated circuits (that’s how the acronym is deciphered). Now, the first ASICs for Ethereum came out in April 2018, and they were more than a curious gadget than a serious rival to GPUs. Vitalik Buterin said that they were not a threat and the best action would be no action. But the situation changed. Soon, there were ASICs twice as efficient as the best graphic cards. Still, it wasn’t enough to justify the price difference. Finally, in late September 2019, Chinese manufacturer and distributor of mining hardware Canaan announced that it would start selling a new ASIC that is 5 to 7 times more efficient than the leading GPU models.Its W/MHs ratio is just 0.68–7.5 times better compared to AMD Vega 64 and 5.3 times better than AMD RX570. What does this mean for Ethereum mining? When such models go on sale, whoever can afford them will be able to extract very high profits. GPU miners will be at a disadvantage. And if you have only a small rig with a couple of GPUs at home, your prospects are grim. You might ask: can’t Ethereum devs do something — say, change the algorithm? Bitcoin algo changes regularly, after all. Unfortunately, Ethereum works differently, so every algorithm change would require a hard fork — with all the consequences it entails. The devs have been talking about introducing a new consensus protocol called ProgPOW (Programmable Proof of Work). It would make the algorithm change regularly and ensure ASIC resistance. But Vitalik Buterin believes that the real goal is a switch to Proof of Stake, not tweaking PoW. What other options are there to protect small miners from the upcoming wave of ASICs? In our next post, we’ll explain how 2Ether plans to deal with this problem. https://2ether.com/ Web site — https://2ether.com/ Twitter — https://twitter.com/2Ether_ Discord — https://discord.gg/TuqG4py Facebook — https://www.facebook.com/2Ethe Reddit — https://www.reddit.com/use2Ether Medium — https://medium.com/@2ether Teletype — https://teletype.in/@2ether Telegram — https://t.me/ether2support Telegram chat — https://t.me/blockchain_2ether
I don't buy new laptops and when I do I try and get the most out of my graphics. Before you AMD ass lickers ban me, I like AMD. If I was going to Build a pc it would at least have an AMD cpu and maybe an 5700XT. I bought myself an Alienware,32gb ram, I7 6th gen and gtx 1070 for £600. Why I N T E L and N V I D I A? Easy answer. A Full AMD machine is S H I T. I can still see AMD fanboys saying "OMG FX were still good". NO! You can call me whatever you want but I like the better side. I liked Intel until this year which is when AMD really took over. Anyways I got sidetracked there. I only have one pc (bitcoin miner) with a GTX 1080 and I N T E L 2 quad (mining is gpu but not cpu intensive) and AMD does a very bad job in mining. So I only use a laptop. I'm going to change my laptop in about 3 years and it will be a 2/3 year old but still capable laptop. SO DOES THAT MEAN ITS GOING TO AMD? Cause you know AMD is the best. Here I'm going to dissapoint you. I have to be on the go and I cant have a pc. I never said I like AMD LAPTOP cpu's. In 3 years I'm getting a laptop with a 6 core cpu. Sadly AMD doesn't offer you 6 cores. BUT WAIT 7NM!!! Nope 12nm. BUT...... BUT ITS CHEAPER. I don't care the laptop is going to be cheap anyway. All higher end AMD cpu's have 4 cores. Here I want to start a discution and petition to have 6/8 core mobile Ryzen cpu's. And you know since AMD likes pushing make 12 core mobile cpu's.
Why is the RandomX algorithm being hyped to the moon?
TL;DR: don't assume the average return from mining RandomX will be higher than the current CryptonightR algorithm. Hold back your excitement for now. I think we all need to bring something to our attention. Over the last month, there have been so many topics and comments here on MoneroMining about the new 'RandomX' algorithm. This algorithm is supposed to be launched a couple of months from now. There are many questions like "is this a good hashrate for my CPU"? "What's your power usage on RandomX"? "How can I tune my CPU for RandomX"? "How would the algorithm perform on this hardware"? I think these are great constructive comments that are at the heart of what miners stand for. We miners love optimizing our rigs and educating ourselves on technological trends. But I've noticed many questions such as "what parts should I buy for a RandomX mining rig"? "Is an AMD Ryzen 9 3900x a good investment"? "What parts will give me the most profit when RandomX launches"? Many of these questions are asked with very little research. I think there's a gold fever brewing behind some of these comments. The kind of motives that have bankrupted many miners in the past bubbles. As we have seen in 2014 and 2018, anybody who enters the crypto industry with an 'I want easy profit' attitude almost always goes bankrupt. They buy coins or hardware at the peak of the bubble. Sometimes they get lucky and sell their coins or rigs right before the crash (only to get burned in a future bubble later). But most of the time, these new users lose most of their investment. As a veteran miner, a lot of alarm bells ring in my head when I read these kinds of RandomX hype posts. I have no reason to think CPU mining will be more profitable on RandomX than on the current CryptonightR.
If the new AMD CPUs are very efficient on RandomX, that just means more people will buy them, driving up the difficulty. Your shiny R9 3900x's profit will start falling because it's no longer as competitive against the other hardware on the network.
If the profits on day 1 of the RandomX launch are indeed high, more people will start adding rigs to the network. If the average miner's profit is above the equilibrium of the market, it will start going down. That equilibrium is largely set by botnets, large scale farms in China/Russia/Niagara Falls/Georgia, and datacenters with spare capacity. So if your R9 3900x earns $10/day on day 1, you can count on that golden streak ending soon.
CPU mining as a market is never stable. Your CPU rig is limited tojust 1 or 2 coins: Monero and Veruscoin. Edit: there are a few more CPU coins than these. AMD GPUs can at least mine 3 or 4 coins well, while nVidia GPUs are the best at 5-10 different algorithms. GPU mining is a safer, less risky investment. GPU mining is like playing blackjack. Building a rig specifically for CPU mining is like tossing a coin. You're locked into one coin by building a CPU rig. Yes, it has resale value to gamers, but it's much harder to resell a MOBO combo than a bunch of GPUs at any price. Trust me, I've sold hundreds of GPUs and dozens of MOBOs before!
I don't know what the market share of CPUs vs. GPUs on CryptonightR is right now. But if most of the current nethash is made up of CPUs, these CPUs will have no choice but to switch to RandomX when it is out. There's no other coin for them to mine, unless they have some work to do outside of mining. So almost all of them will get onto the RandomX network, too, along with your expensive new CPU rig. I think this'll be the biggest factor driving up difficulty. Yes, the older CPUs might not be as efficient as the new Ryzens, but many of them are already paid for in terms of capital (like in a datacenter) or have free power (like in a botnet or apartment with free power).
You might say that Monero will always be profitable enough because it has survived so long, or the developers are better, or they're taking action against ASICs. But that doesn't necessarily guarantee profit. Monero might be a successful coin and overtake ETH, but that has nothing to do with profit on the network. Even though Bitcoin's really successful, you're guaranteed to lose money if you buy the latest Antminer and run it at residential power rates. Meanwhile, Dogecoin back in the day had awesome profits even though it was a blatant fork of LTC with few improvements.
Your new RandomX rig might look like it has decent "ROI" to you, but that doesn't mean it was the best investment. You might have been better off building a GPU rig and mining Grincoin or Ravencoin. I.E. if you build a RandomX rig, you're earning less profit for the same amount of capital invested. And even if you earn the same return, you still took a higher risk than if you built a GPU rig (see the point above).
In the GPU mining community, I have the feeling that there's a lot of resentment over the 2018 crypto recession and the whole 'ASIC miner invasion'. I think people here are feeling burned over their losses last year and the evil ASIC takeover, and want an opportunity for the little guy to start mining again. So we're falsely seeing the RandomX ray of hope as a floodlight, and getting overexcited. And in general, the ordinary person cannot make a significant, steady profit in the crypto mining industry. The guy who wrote that thread is very rich and even 100 GTX 1080 Ti's cost nothing to him. The reason he became wealthy is because he avoided get-rich-quick gimmicks back in the day (like the dotcom sites) and focused on learning technology for the future. Mining will not make you rich, and especially not RandomX coin tossing. If you love RandomX, build your rig now, keep benchmarking and undervolting and have fun at it. But if you just want profit, wait until RandomX is up and running. And consider all the risks involved with a new algorithm and commercial mining in general. So I hope we can all reconsider whether we're excited about RandomX for the right reasons. Let's try to avoid jumping to conclusions about profitability and hold off on the Newegg 'checkout' button. Even though 12 cores at 70 watts sounds awesome. Happy mining!
Transcript of discussion between an ASIC designer and several proof-of-work designers from #monero-pow channel on Freenode this morning
[08:07:01] lukminer contains precompiled cn/r math sequences for some blocks: https://lukminer.org/2019/03/09/oh-kay-v4r-here-we-come/ [08:07:11] try that with RandomX :P [08:09:00] tevador: are you ready for some RandomX feedback? it looks like the CNv4 is slowly stabilizing, hashrate comes down... [08:09:07] how does it even make sense to precompile it? [08:09:14] mine 1% faster for 2 minutes? [08:09:35] naturally we think the entire asic-resistance strategy is doomed to fail :) but that's a high-level thing, who knows. people may think it's great. [08:09:49] about RandomX: looks like the cache size was chosen to make it GPU-hard [08:09:56] looking forward to more docs [08:11:38] after initial skimming, I would think it's possible to make a 10x asic for RandomX. But at least for us, we will only make an ASIC if there is not a total ASIC hostility there in the first place. That's better for the secret miners then. [08:13:12] What I propose is this: we are working on an Ethash ASIC right now, and once we have that working, we would invite tevador or whoever wants to come to HK/Shenzhen and we walk you guys through how we would make a RandomX ASIC. You can then process this input in any way you like. Something like that. [08:13:49] unless asics (or other accelerators) re-emerge on XMR faster than expected, it looks like there is a little bit of time before RandomX rollout [08:14:22] 10x in what measure? $/hash or watt/hash? [08:14:46] watt/hash [08:15:19] so you can make 10 times more efficient double precisio FPU? [08:16:02] like I said let's try to be productive. You are having me here, let's work together! [08:16:15] continue with RandomX, publish more docs. that's always helpful. [08:16:37] I'm trying to understand how it's possible at all. Why AMD/Intel are so inefficient at running FP calculations? [08:18:05] midipoet ([email protected]/web/irccloud.com/x-vszshqqxwybvtsjm) has joined #monero-pow [08:18:17] hardware development works the other way round. We start with 1) math then 2) optimization priority 3) hw/sw boundary 4) IP selection 5) physical implementation [08:22:32] This still doesn't explain at which point you get 10x [08:23:07] Weren't you the ones claiming "We can accelerate ProgPoW by a factor of 3x to 8x." ? I find it hard to believe too. [08:30:20] sure [08:30:26] so my idea: first we finish our current chip [08:30:35] from simulation to silicon :) [08:30:40] we love this stuff... we do it anyway [08:30:59] now we have a communication channel, and we don't call each other names immediately anymore: big progress! [08:31:06] you know, we russians have a saying "it was smooth on paper, but they forgot about ravines" [08:31:12] So I need a bit more details [08:31:16] ha ha. good! [08:31:31] that's why I want to avoid to just make claims [08:31:34] let's work [08:31:40] RandomX comes in Sep/Oct, right? [08:31:45] Maybe [08:32:20] We need to audit it first [08:32:31] ok [08:32:59] we don't make chips to prove sw devs that their assumptions about hardware are wrong. especially not if these guys then promptly hardfork and move to the next wrong assumption :) [08:33:10] from the outside, this only means that hw & sw are devaluing each other [08:33:24] neither of us should do this [08:33:47] we are making chips that can hopefully accelerate more crypto ops in the future [08:33:52] signing, verifying, proving, etc. [08:34:02] PoW is just a feature like others [08:34:18] sech1: is it easy for you to come to Hong Kong? (visa-wise) [08:34:20] or difficult? [08:34:33] or are you there sometimes? [08:34:41] It's kind of far away [08:35:13] we are looking forward to more RandomX docs. that's the first step. [08:35:31] I want to avoid that we have some meme "Linzhi says they can accelerate XYZ by factor x" .... "ha ha ha" [08:35:37] right? we don't want that :) [08:35:39] doc is almost finished [08:35:40] What docs do you need? It's described pretty good [08:35:41] so I better say nothing now [08:35:50] we focus on our Ethash chip [08:36:05] then based on that, we are happy to walk interested people through the design and what else it can do [08:36:22] that's a better approach from my view than making claims that are laughed away (rightfully so, because no silicon...) [08:36:37] ethash ASIC is basically a glorified memory controller [08:36:39] sech1: tevador said something more is coming (he just did it again) [08:37:03] yes, some parts of RandomX are not described well [08:37:10] like dataset access logic [08:37:37] RandomX looks like progpow for CPU [08:37:54] yes [08:38:03] it is designed to reflect CPU [08:38:34] so any ASIC for it = CPU in essence [08:39:04] of course there are still some things in regular CPU that can be thrown away for RandomX [08:40:20] uncore parts are not used, but those will use very little power [08:40:37] except for memory controller [08:41:09] I'm just surprised sometimes, ok? let me ask: have you designed or taped out an asic before? isn't it risky to make assumptions about things that are largely unknown? [08:41:23] I would worry [08:41:31] that I get something wrong... [08:41:44] but I also worry like crazy that CNv4 will blow up, where you guys seem to be relaxed [08:42:06] I didn't want to bring up anything RandomX because CNv4 is such a nailbiter... :) [08:42:15] how do you guys know you don't have asics in a week or two? [08:42:38] we don't have experience with ASIC design, but RandomX is simply designed to exactly fit CPU capabilities, which is the best you can do anyways [08:43:09] similar as ProgPoW did with GPUs [08:43:14] some people say they want to do asic-resistance only until the vast majority of coins has been issued [08:43:21] that's at least reasonable [08:43:43] yeah but progpow totally will not work as advertised :) [08:44:08] yeah, I've seen that comment about progpow a few times already [08:44:11] which is no surprise if you know it's just a random sales story to sell a few more GPUs [08:44:13] RandomX is not permanent, we are expecting to switch to ASIC friendly in a few years if possible [08:44:18] yes [08:44:21] that makes sense [08:44:40] linzhi-sonia: how so? will it break or will it be asic-able with decent performance gains? [08:44:41] are you happy with CNv4 so far? [08:45:10] ah, long story. progpow is a masterpiece of deception, let's not get into it here. [08:45:21] if you know chip marketing it makes more sense [08:45:24] linzhi-sonia: So far? lol! a bit early to tell, don't you think? [08:45:35] the diff is coming down [08:45:41] first few hours looked scary [08:45:43] I remain skeptical: I only see ASICs being reasonable if they are already as ubiquitous as smartphones [08:45:46] yes, so far so good [08:46:01] we kbew the diff would not come down ubtil affter block 75 [08:46:10] yes [08:46:22] but first few hours it looks like only 5% hashrate left [08:46:27] looked [08:46:29] now it's better [08:46:51] the next worry is: when will "unexplainable" hashrate come back? [08:47:00] you hope 2-3 months? more? [08:47:05] so give it another couple of days. will probably overshoot to the downside, and then rise a bit as miners get updated and return [08:47:22] 3 months minimum turnaround, yes [08:47:28] nah [08:47:36] don't underestimate asicmakers :) [08:47:54] you guys don't get #1 priority on chip fabs [08:47:56] 3 months = 90 days. do you know what is happening in those 90 days exactly? I'm pretty sure you don't. same thing as before. [08:48:13] we don't do any secret chips btw [08:48:21] 3 months assumes they had a complete design ready to go, and added the last minute change in 1 day [08:48:24] do you know who is behind the hashrate that is now bricked? [08:48:27] innosilicon? [08:48:34] hyc: no no, and no. :) [08:48:44] hyc: have you designed or taped out a chip before? [08:48:51] yes, many years ago [08:49:10] then you should know that 90 days is not a fixed number [08:49:35] sure, but like I said, other makers have greater demand [08:49:35] especially not if you can prepare, if you just have to modify something, or you have more programmability in the chip than some people assume [08:50:07] we are chipmakers, we would never dare to do what you guys are doing with CNv4 :) but maybe that just means you are cooler! [08:50:07] and yes, programmability makes some aspect of turnaround easier [08:50:10] all fine [08:50:10] I hope it works! [08:50:28] do you know who is behind the hashrate that is now bricked? [08:50:29] inno? [08:50:41] we suspect so, but have no evidence [08:50:44] maybe we can try to find them, but we cannot spend too much time on this [08:50:53] it's probably not so much of a secret [08:51:01] why should it be, right? [08:51:10] devs want this cat-and-mouse game? devs get it... [08:51:35] there was one leak saying it's innosilicon [08:51:36] so you think 3 months, ok [08:51:43] inno is cool [08:51:46] good team [08:51:49] IP design house [08:51:54] in Wuhan [08:52:06] they send their people to conferences with fake biz cards :) [08:52:19] pretending to be other companies? [08:52:26] sure [08:52:28] ha ha [08:52:39] so when we see them, we look at whatever card they carry and laugh :) [08:52:52] they are perfectly suited for secret mining games [08:52:59] they made at most $6 million in 2 months of mining, so I wonder if it was worth it [08:53:10] yeah. no way to know [08:53:15] but it's good that you calculate! [08:53:24] this is all about cost/benefit [08:53:25] then you also understand - imagine the value of XMR goes up 5x, 10x [08:53:34] that whole "asic resistance" thing will come down like a house of cards [08:53:41] I would imagine they sell immediately [08:53:53] the investor may fully understand the risk [08:53:57] the buyer [08:54:13] it's not healthy, but that's another discussion [08:54:23] so mid-June [08:54:27] let's see [08:54:49] I would be susprised if CNv4 ASICs show up at all [08:54:56] surprised* [08:54:56] why? [08:55:05] is only an economic question [08:55:12] yeah should be interesting. FPGAs will be near their limits as well [08:55:16] unless XMR goes up a lot [08:55:19] no, not *only*. it's also a technology question [08:55:44] you believe CNv4 is "asic resistant"? which feature? [08:55:53] it's not [08:55:59] cnv4 = Rabdomx ? [08:56:03] no [08:56:07] cnv4=cryptinight/r [08:56:11] ah [08:56:18] CNv4 is the one we have now, I think [08:56:21] since yesterday [08:56:30] it's plenty enough resistant for current XMR price [08:56:45] that may be, yes! [08:56:55] I look at daily payouts. XMR = ca. 100k USD / day [08:57:03] it can hold until October, but it's not asic resistant [08:57:23] well, last 24h only 22,442 USD :) [08:57:32] I think 80 h/s per watt ASICs are possible for CNv4 [08:57:38] linzhi-sonia where do you produce your chips? TSMC? [08:57:44] I'm cruious how you would expect to build a randomX ASIC that outperforms ARM cores for efficiency, or Intel cores for raw speed [08:57:48] curious [08:58:01] yes, tsmc [08:58:21] Our team did the world's first bitcoin asic, Avalon [08:58:25] and upcoming 2nd gen Ryzens (64-core EPYC) will be a blast at RandomX [08:58:28] designed and manufactured [08:58:53] still being marketed? [08:59:03] linzhi-sonia: do you understand what xmr wants to achieve, community-wise? [08:59:14] Avalon? as part of Canaan Creative, yes I think so. [08:59:25] there's not much interesting oing on in SHA256 [08:59:29] Inge-: I would think so, but please speak [08:59:32] hyc: yes [09:00:28] linzhi-sonia: i am curious to hear your thoughts. I am fairly new to this space myself... [09:00:51] oh [09:00:56] we are grandpas, and grandmas [09:01:36] yet I have no problem understanding why ASICS are currently reviled. [09:01:48] xmr's main differentiators to, let's say btc, are anonymity and fungibility [09:01:58] I find the client terribly slow btw [09:02:21] and I think the asic-forking since last may is wrong, doesn't create value and doesn't help with the project objectives [09:02:25] which "the client" ? [09:02:52] Monero GUI client maybe [09:03:12] MacOS, yes [09:03:28] What exactly is slow? [09:03:30] linzhi-sonia: I run my own node, and use the CLI and Monerujo. Have not had issues. [09:03:49] staying in sync [09:03:49] linzhi-sonia: decentralization is also a key principle [09:03:56] one that Bitcoin has failed to maintain [09:04:39] hmm [09:05:00] looks fairly decentralized to me. decentralization is the result of 3 goals imo: resilient, trustless, permissionless [09:05:28] don't ask a hardware maker about physical decentralization. that's too ideological. we focus on logical decentralization. [09:06:11] physical decentralization is important. with bulk of bitnoin mining centered on Chinese hydroelectric dams [09:06:19] have you thought about including block data in the PoW? [09:06:41] yes, of course. [09:07:39] is that already in an algo? [09:08:10] hyc: about "centered on chinese hydro" - what is your source? the best paper I know is this: https://coinshares.co.uk/wp-content/uploads/2018/11/Mining-Whitepaper-Final.pdf [09:09:01] linzhi-sonia: do you mine on your ASICs before you sell them? [09:09:13] besides testing of course [09:09:45] that paper puts Chinese btc miners at 60% max [09:10:05] tevador: I think everybody learned that that is not healthy long-term! [09:10:16] because it gives the chipmaker a cost advantage over its own customers [09:10:33] and cost advantage leads to centralization (physical and logical) [09:10:51] you guys should know who finances progpow and why :) [09:11:05] but let's not get into this, ha ha. want to keep the channel civilized. right OhGodAGirl ? :) [09:11:34] tevador: so the answer is no! 100% and definitely no [09:11:54] that "self-mining" disease was one of the problems we have now with asics, and their bad reputation (rightfully so) [09:13:08] I plan to write a nice short 2-page paper or so on our chip design process. maybe it's interesting to some people here. [09:13:15] basically the 5 steps I mentioned before, from math to physical [09:13:32] linzhi-sonia: the paper you linked puts 48% of bitcoin mining in Sichuan. the total in China is much more than 60% [09:13:38] need to run it by a few people to fix bugs, will post it here when published [09:14:06] hyc: ok! I am just sharing the "best" document I know today. it definitely may be wrong and there may be a better one now. [09:14:18] hyc: if you see some reports, please share [09:14:51] hey I am really curious about this: where is a PoW algo that puts block data into the PoW? [09:15:02] the previous paper I read is from here http://hackingdistributed.com/2018/01/15/decentralization-bitcoin-ethereum/ [09:15:38] hyc: you said that already exists? (block data in PoW) [09:15:45] it would make verification harder [09:15:49] linzhi-sonia: https://the-eye.eu/public/Books/campdivision.com/PDF/Computers%20General/Privacy/bitcoin/meh/hashimoto.pdf [09:15:51] but for chips it would be interesting [09:15:52] we discussed the possibility about a year ago https://www.reddit.com/Monero/comments/8bshrx/what_we_need_to_know_about_proof_of_work_pow/ [09:16:05] oh good links! thanks! need to read... [09:16:06] I think that paper by dryja was original [09:17:53] since we have a nice flow - second question I'm very curious about: has anyone thought about in-protocol rewards for other functions? [09:18:55] we've discussed micropayments for wallets to use remote nodes [09:18:55] you know there is a lot of work in other coins about STARK provers, zero-knowledge, etc. many of those things very compute intense, or need to be outsourced to a service (zether). For chipmakers, in-protocol rewards create an economic incentive to accelerate those things. [09:19:50] whenever there is an in-protocol reward, you may get the power of ASICs doing something you actually want to happen [09:19:52] it would be nice if there was some economic reward for running a fullnode, but no one has come up with much more than that afaik [09:19:54] instead of fighting them off [09:20:29] you need to use asics, not fight them. that's an obvious thing to say for an asicmaker... [09:20:41] in-protocol rewards can be very powerful [09:20:50] like I said before - unless the ASICs are so useful they're embedded in every smartphone, I dont see them being a positive for decentralization [09:21:17] if they're a separate product, the average consumer is not going to buy them [09:21:20] now I was talking about speedup of verifying, signing, proving, etc. [09:21:23] they won't even know what they are [09:22:07] if anybody wants to talk about or design in-protocol rewards, please come talk to us [09:22:08] the average consumer also doesn't use general purpose hardware to secure blockchains either [09:22:14] not just for PoW, in fact *NOT* for PoW [09:22:32] it requires sw/hw co-design [09:23:10] we are in long-term discussions/collaboration over this with Ethereum, Bitcoin Cash. just talk right now. [09:23:16] this was recently published though suggesting more uptake though I guess https://btcmanager.com/college-students-are-the-second-biggest-miners-of-cryptocurrency/ [09:23:29] I find it pretty hard to believe their numbers [09:24:03] well [09:24:09] sorry, original article: https://www.pcmag.com/news/366952/college-kids-are-using-campus-electricity-to-mine-crypto [09:24:11] just talk, no? rumors [09:24:18] college students are already more educated than the average consumer [09:24:29] we are not seeing many such customers anymore
