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.
