There is a new fork of GRIN based on the MimbleWimble protocol called Epic Cash (EPIC) that has officially launched their blockchain a day or so ago. EPIC can be CPU, GPU, and ASIC-mined with 3 different algorithms available for each type of hardware and block rewards are distributed according to a schedule that balances wide distribution with long-term security. One of the main goals of the project is to offer high level of privacy to the users with a monetary policy very similar to that of Bitcoin (BTC). This includes a maximum supply of 21 million coins and a higher initial emission in order to reach and synchronize with Bitcoin in terms of available coins in a couple of years time frame. The so called Epic Singularity will happe in 2028 when the Epic circulating supply intersects the number of Bitcoin’s circulating supply, at which point Epic Cash adopts the Bitcoin block reward and halving pattern. Until then the starting block reward is 16 coins halving around every year initially and then around every two until it reaches a halving every 4 years.

The Epic Cash blockchain is initially available to CPU, GPU, and ASIC miners by using three respective hashing algorithms: RandomX, ProgPow, and CuckAToo31+ wih different percent distribution for each one starting with higher CPU advantage and slowly transitioning to GPUs and then ASICs. Since for the moment there are not publicly available CuckAToo31+ ASIC miners the algo is available for GPUs as well, however work is being done by multiple manufacturers and maybe by the end of this year or early next year such devices might become available on the market (optimistically speaking). So far, so good the project looks interesting and promising, though not everything seems to be that great for non-advanced users interested in mining EPIC.

First of all EPIC can currently be only solo mined and since it is based on GRIN codebase, just like GRIN it is not that user friendly running and mining it. LINUX users have a better advantage as for example the CUDA GPU miner is not officially available for Windows yet and the OpenCL one is giving trouble and using third party ProgPow miners for solo mining the coin is also a kind of a challenge with no pool available yet. CPU mining is working pretty well with the available miner, but solo mining with the already high difficulty could be a challenge for most users to mine even one block. mining pools should be coming out shortly with talk about icemining probably being the first on the train, though nothing official about that yet.

Today is planned the first hardfork for the GRIN crypto currency and more specifically its Cuckaroo29 (C29) algorithm to the new Cuckarood29, the C31 algorithm remains unaffected by this hardfork. Grin is expected to hard fork at Block 262,080 which is estimated to happen at some point today (July 17th, 2019). All you have to do to be ready to continue mining GRIN after the hardfork is to update your miner to the latest version, most of the software supports autodetection of the algorithm switch and thus should continue working jst fine after the fork happens.

The miners that have already released updates to support the new Cuckarood29 algorithm to be sued by Grin after the hard fork include: GMiner 1.51, NBMiner 24.1, lolMiner 0.8.5, nanominer 1.5.1 for AMD and or Nvidia GPUs on Windows and Linux operating systems. You can of course also use the official grin-miner 2.0.0 as well, although it is not available for Windows operating systems (only Linux and Mac OS X), unlike all of the other alternatives mentioned.

The latest two version of GMiner 1.46 come with more performance boost for the following supported algorithms: Grin29 (GRIN), Aeternity (AE) and SWAP on Nvidia GPUs and especially for GTX 1080 Ti mining rig owners. The performance boost is not that significant, but any bit of extra hashrate is welcome, so make sure you update to get a bit better hashrate. The new version also adds support for the Equihash 125,4 algorithm for Nvidia cards that is being used by ZelCash.

The GMiner miner requires an Nvidia GPU with CUDA compute capability 5.0 or later as well as CUDA 9.0 driver support, some algorithms are already supported on AMD GPUs as well (Cuckaroo29, Cuckoo29, Cuckaroo29s, Beam’s Equihash 150,5, Equihash 144,5 and 192,7. Do note that GMiner is a closed source miner for Nvidia and AMD GPUs with binaries available for both Windows and Linux, also there is a 2% developer fee built-in the software.
