Grin is a new crypto project for creating a the private and lightweight mimblewimble blockchain that would provide electronic transactions for everyone without censorship or restrictions. The algorithm that Grin uses is Cuckoo Cycle with 1 minute block time, 60 GRIN block reward and no limit on coin supply or reward halving. There is not going to be any ICO, founders reward, pre-mine or masternodes available for this project, so people that do not like any of these should be Ok with this project. Miners for Grin are still currently being developed, although there are some already announced or available, though initially it could be a bit of a challenge to make things work with the right miner and pool. For instance the official MWGrinPool is currently not taking new registrations, though new pools should be available as alternatives. There are already a couple of options for pools on the Testnet where you can test the mining before the Mainnet launch like Spark Pool.

The official open-source Grin Miner software is currently only available for Linux and Mac OS X and it supports both CUDA and OpenCL mining. For miners looking for Windows miners there is the Grin Gold Miner (with 1% fee for the Grin Development Fund and 1% fee for further miner development), although it also works with Linux) that supports all AMD and NVIDIA 8GB cards (requires a GPU with 8GB VRAM!). Do note however that Nvdia RTX 8GB cards need Linux or Windows 7 due to memory addressing issues. RTX 2080 and RTX 2080 Ti are fastest in terms of performance if you manage to make them work, OpenCL code for AMD cards is currently still being optimized. Cheaper slower Celeron CPUs are not recommended for many cards on the system (similar to Merit and BITC that also use the same algorithm for mining). Another alternative for Windows miners should be the GrinPro Miner that is not yet available for download and that will have 2% developer fee. This miner should work on AMD and Nvidia GPUs with 8GB VRAM, although it promises upcoming support for 6GB VRAM cards as well, so that could be interesting for some users.

Unfortunately zjazz, who was pretty active in miner development for Cuckoo Cycle support for Merit and BITC hasn’t updated his miner for a while and will probably not be supporting Grin mining at least for the moment. The latest version of Bminer that was just made available however also comes with experimental support for mining Grin, so you might want to check it out as well. Do note that it is a closed source miner with 2% developer fee, so have that in mind as well when checking out different miners for Grin. The latest version of the closed source miner NBMiner has also just added support for the Cuckaroo algorithm used by Grin (both Windows and Linux), so you can give it a try as well (Nvidia only).

If you are mining Merit (Cuckoo Cycle Edgebit 26), Bitcash (Cuckoo Cycle Edgebit 27) or SUQA (X22i) on AMD or Nvidia GPUs you might want to check the just released update for the zjazz CUDA and OpenCL 1.2 closed source miner and start using it or just upgrade if using older version. Both the AMD and the Nvidia versions (separate downloads) of the zjazz 1.2 miner come with stratum connection stability improved (should help efficiency on all supported algorithms), but AMD users also get some optimizations added to X22i algorithm or with other words some additional performance increase should be noticeable.

The Cuckoo Cycle algorithm used by MRT and BITC is CPU intensive and the zjazz miner provides multiple options to reduce the CPU load if you are mining on a GPU mining rig with a slower processor that is having trouble coping up, so make sure you check these out. Do note that the zjazz miner is a closed source software available as binary releases for both Windows and Linux and comes with a built-in development fee of 2%.

There is a new update of the zjazz CUDA Miner 0.97 for the Cuckoo Cycle algorithm that is being used by the Merit (MRT) and BitCash (BITC) projects. The new version comes with a number of improvements in functionality improvements, including support for BitCash mining on 3GB Nvdia GPUs (Merit was already supported on these), basic ccminer-like API support, list of failover pools is now supported and more to make mining better and problem free experience. You can find the full changelog of the new release below.

zjazz CUDA Miner 0.97 Changelog:
