The much anticipated Constantinople hardfork of Ethereum was initially planned for the middle of January, however a serious bug was discovered shortly before the time of the fork, so it was postponed. The new date for for Ethereum’s latest network hardfork system upgrade is around 27-28 February (end of the month) or more specifically at block number 7,280,000 (200,000 blocks later than the originally planed block). The hardfork will be in two parts, the first one will include all five EIPs (Ethereum Improvement Proposals) including the problematic EIP 1283, that was the reason to postpone the fork initially, and the second part will be used to remove the problematic EIP 1283. So after the Constantinople and Petersburg hardfork (the two parts we are talking about) the Ethereum network will have the following 4 EIPs active – 145, 1014, 1052 and 1234.

The improvements to the Ethereum network that the new hardfork will bring are numerous and they focus on improving salability, speed and efficiency of the blockchain. There is however a change that is also important to the economics of the Ethereum network and one that is especially important for miners. EIP 1234 is going to adjust the block reward, so after the fork miners will be getting just 2 ETH coins per block instead of the 3 ETH that they are getting at the moment. There isn’t much needed from you to do in order to be ready for the hardfork if you are using or mining Ether, just make sure you update any local wallet or client that you might be running. Also make sure to not make any transactions around the time of the hardfork in order to avoid any possible issues with delayed transactions and lost coins, though normally such problems are not very likely.

The US Securities and Exchange Commission (SEC) has released official guide regarding crypto Initial Coin Offerings (ICOs) in order to help both investors and professionals interested in participating or starting such a project. Companies and individuals are increasingly considering initial coin offerings (ICOs) as a way to raise capital or participate in investment opportunities. While these digital assets and the technology behind them may present a new and efficient means for carrying out financial transactions, they also bring increased risk of fraud and manipulation because the markets for these assets are less regulated than traditional capital markets.

The latest update of the AMD GPU miner lolMiner 0.7 alpha5 brings support for BEAM (Equihash 150,5 algorithm) on NiceHash giving access to AMD miners to sell their hashrate on the platform. In the last day the most profitable hashrate selling was for BEAM on NiceHash, but unfortunately not for AMD… it was for Nvidia miners with higher-end GPUs. Nevertheless, AMD miners now have access to sell their Equihash 150,5 hashrate as well on NiceHash with the lolMiner 0.7 alpha5, just make sure you set TLS to off for use with NiceHash (--tls 0 in cmd or "TLS" : 0 in config file to turn if off for BEAM). We remind you that lolMiner is a closed source AMD GPU miner available for Windows and Linux as pre-compiled binaries only and that there is a developer fee for using the software.

The new AMD Radeon VII (gfx906) GPUs are about to start hitting the market any moment now with a recommended end user price of $699 USD in USA or 739 EURO in EU. We just got a tip that these new 7nm GPUs from AMD with 16GB HBM2 video memory are able to deliver about 90 MHS for Ehereum’s Ethash algorithm out of the box without any overclock. This is possible with the latest Claymore Dual GPU Miner v12.0, so really out of the box performance very close to the 90 MHS mark for Ethereum. So the new HBM2 memory with 4096-bit memory bus and 1000 MHz (effective 2000 MHz memory clock) seem to be doing quite well for memory intensive crypto algorithms.

We are of course still about to see what the performance for GPU intensive algorithms is going to be and this might also need some specific optimizations for the new GPUs in order to get the maximum performance. With the presence of 3840 stream processors the new Radeon VII GPUs should have plenty of raw power available for GPU-heavy lifting including, but not limited to crypto hashing. We are quite pleased to see the good memory performance for Ethash and expect good results for other algorithms as well, so hopefully very soon more performance data for crypto mining for the new AMD Radeon VII will surface…

The latest Bminer 14.2.0 has just been released with experimental support for Cuckatoo31 (C31) algorithm being used by GRIN for Nvidia GeForce GTX 1080 Ti GPUs with claimed performance of up to about 0.90 G/s on GTX 1080 Ti with stock settings. This seems pretty good, however we are currently unable to make the miner work properly under Windows 10 as we are getting an error about insufficient memory available on device and it seems other people are reporting the same issue (it is experimental support). Do note that GRIN mining support on NiceHash is not yet available for Bminer and that goes for both Cuckaroo29 and Cuckatoo31 algorithms, so you can instead use the latest GMiner for NiceHash.

We remind you that that Bminer is a closed source Nvidia GPU miner available for Linux and Windows in the form of pre-compiled binaries and that there is a 2% development fee for Grin, Beam, Bytom (BTM), Equihash and Zhash coins, 0.65% for Ethash and 1.3% for dual mining Ethash and Blake.

The latest GMiner version 1.31 brings an important update for everyone interested in Grin mining, namely support for Grin’s Cuckatoo31 algorithm to Windows miners as previously the C31 algo was only available with the official Grin miner for Linux and Mac OS X. Do note that Cuckatoo31 support (Grin31)requires 7.4 GB VRam, will work on 8GB cards under Linux and Windows 7, but will not work under Windows 10. Video cards such as GTX 1080 Ti do work under Windows 10 and should be able to provide about 0.6-0.7 G/s hashrate for C31. The latest update should now work fine with both C29 and C31 for Grin in NiceHash as well as there were some issues with the last few versions and NiceHash in the last days due to changes happening with the Grin support.

The GMiner Nvidia CUDA miner requires an Nvidia GPU with CUDA compute capability 5.0 or later as well as CUDA 9.0 driver support. Do note that GMiner is a closed source miner for Nvidia GPUs with binaries available for both Windows and Linux, also there is a 2% developer fee built-in the software.

After the recent addition of BEAM (Equihash 150,5) support on NiceHash the service for selling and buying mining hashrate has become more active and has just added two (three) more new algorithms – CuckARoo29 and CuckAToo31 used by GRIN and Lyra2REv3 used by VTC. NiceHash support for GRIN on the software side is still somewhat lacking, with the latest GMiner 1.28 pretty much currently the only available miner for Grin (CuckARoo29) available for Nvidia GPUs under Windows, no AMD Grin miners with proper NiceHash support for now it seems. Lyra2REv3 on the other hand is more widely supported and available already on multiple software miners for both AMD and Nvidia as it was an anticipated fork for VTC, so developers had the time to get ready. An example for a compatible AMD miner is the latest WildRig Multi and for Nvidia you can try the latest official ccminer by tpruvot or the latest CryptoDredge which is faster in terms of performance compared to ccminer. Due to the interest and demand for Grin mining hashrate currently profitability wise it might be interesting for Nvidia miners to try selling their hashrate on NiceHash and get paid in BTC for it while waiting for the Grin ecosystem to get more developed and functional that it is at the moment.

GMiner has been updated a lot recently with fixes and improvements and the latest version 1.26 is not an exception as it apparently tires to fix the BEAM mining support on NiceHash that has recently been introduced. Initially when NiceHash announced support for BEAM on their platform both GMiner and Bminer seemed to work just fine, however earlier today both miners started having issues with the platform. The problem seems to affect both miners for BEAM only on NiceHash, it does seem to work fine with other mining pools, but on NiceHash you are getting a lot of rejected shares with Bminer and pretty much all rejected n GMiner.

The just released Gminer v1.26 apparently tries to fix that and seems to succeed to some point, however after a while with everything seeming normal we are seeing the latest GMiner getting into a kind of look restarting itself without continuing to mine after that. The time it takes for the restarting loop does seem to vary from a mining rig to a mining rig, we have tried with a couple of them and in less than an hour all of them ended in the same watchdog reboot look for the miner. Running GMiner 1.26 on another pool for BEAM mining seems to be working just fine like with older versions, so the issue is apparently related only to NiceHash support. Of course you are welcome to try out the new miner and report if it works or not for NiceHash BEAM mining.

The GMiner Nvidia CUDA miner requires an Nvidia GPU with CUDA compute capability 5.0 or later as well as CUDA 9.0 driver support. Do note that GMiner is a closed source miner for Nvidia GPUs with binaries available for both Windows and Linux, also there is a 2% developer fee built-in the software.

Update: GMiner v1.26 has been temporary removed until properly fixed, so it is no longer available for download!

It has been a quite a while since the last update of tpruvot’s ccminer fork (source), but there it is a new version 2.3.1 available now that comes with support for Lyra2REv3, sha256q, exosis and Blake2b standard algorithms. The official binary is 64-bit Windows only built with CUDA 10 for SM3+ devices, SM 7.5 architecture is also supported, but doesn’t seem to bring any advantage, for others variants you can build from the source code as the miner is opensource. Do note that CUDA 10 support requires an Nvidia video driver version 410.48 or newer.

The most notable thing abut the new release is the support for Lyra2REv3 that will soon be used by the Vertcoin (VTC) after the upcoming hardfork expected to happen in less than two days. The fork should happen in around February 2nd as it is planned for block 1080000, so make sure you are ready with the required local wallet upgrade (if you are using one) as well as with a miner supporting the new Lyra2REv3 algorithm like the latest ccminer from tpruvot available for Nvidia GPU miners.
