Updated EWBF Cuda Equihash Miner v0.4 With More Solvers

17, Jul 2018

The new EWBF Cuda Equihash Miner is turning out to be the go to miner for Nvidia GPUs when talking about Equihash solvers other than the “original” 200,9 one used by Zcash (ZEC) now that there are ASIC miners available for it. The latest version 0.4 adds support for a new solver for Equihash 210,9 used by AION along with the other already supported Equihash solvers 192,7, 144,5 and 96,5. The latest version also includes some improvements and fixes as well, so if you are using previous version you might want to upgrade to v.04. We are reminding you that the EWBF Cuda Equihash Miner is a closed source miner, there are CUDA 8.0 and 9.1 binaries available for Windows and Linux and there is a 2% developer fee built-in by default.

New EWBF Cuda Equihash Miner v0.1 For GPU Mining

15, Jun 2018

The official Equihash algorithm (equihash 200,9) as used by ZCash (ZEC) may have moved in the domain of ASIC miners, but that does not mean that a modified version of algorithm cannot be still used by other coins and be GPU mined. An example is the Bitcoin Gold (BTG) that is forking to Equihash-BTG (equihash 144,5) and other coins like BitcoinZ (BTCZ) that are forking to equihash 144,5 both of which are not ASIC mineable with Equihash ASIC miners due to the different parameters from the “original” Equihash that uses 200,9. Generally these two variations do require much more video memory in order to work and also the performance in terms of hashrate is significantly lower than that of the original Equihash parameters, so it is hard to make ASIC miners for them.

EWBF, whose original Equihash miner was one of the first and most popular for mining ZCash (ZEC) and other Equihash-based crypto coins, has released a new miner that is targeted at supporting the new Equihash 192,7 and 144,5 algorithms. The new EWBF Cuda Equihash Miner v0.1 is intended for Nvidia GPU mining rigs and is intended for mining of coins that fork from the original Equihash 200,9 algorithm like BTG and BTCZ for example. Aside from options for the two algorithms the miner also comes with an additional option to set personalization string (8 characters) for equihash algorithms that may require this. Do note that this is a closed source miner, there are binaries available for Windows and Linux and there is a 2% developer fee built-in by default.

Bitcoin Gold’s New Equihash-BTG PoW Algorithm

13, Jun 2018

Bitmain’s Equihash ASIC miners Z9 mini as well as Innosilicon’s A9 ZMaster are apparently being shipped and are getting into the hands of some users already. This essentially makes mining Equihash with GPUs pointless and not very profitable, so ZCash (ZEC) is already in the territory of ASIC miners, but not all of the crypto coins that used Equihash are going to just move from GPU mining to ASIC miners. Bitcoin Gold (BTG) for example is going to switch to a new proof of work algorithm they call Equihash-BTG which is essentially a modified version of the Equihash algorithm that will not be ASIC mineable.

Equihash-BTG is essentially going to fork to a modified version of the Equihash PoW algorithm with parameters that will require significantly more memory thus making ASIC miners harder to be made for it and no so efficient. We have already seen that with ASIC miners having a higher memory requirement makes it not impossible, but more like much less efficient performance wise if we consider as an example the Bitmain Antminer E3 ASIC miner for Ethereum’s Ethash algorithm. So Bitcoin Gold (BTC) will not become ASIC resistant forever with its algorithm change, but it will be safe for quite some time at least as we all know when there is an incentive (a lot of money involved) nothing can stop the ASIC miners.

The change of the PoW algorithm used by Bitcoin Gold will become active with a Hard Fork, though there is still no information or a planned block number or date when the fork will happen. So for the moment BTG is still using Equihash and can be mined using ASIC miners designed for this algorithm, but when it switches to the new algorithm it will be GPU mineable again and hopefully it will be still worth mining it by that time.
