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).

After a bit of a delay the official launch of the Veil Project happened earlier today and you can already mine VEIL coins if you are looking for something new and interesting to move your GPU mining rigs on to. Veil is the first Zerocoin-based cryptocurrency with always-on privacy thanks to combining Zerocoin and RingCT technologies to provide full-time privacy without compromise. Veil’s blockchain is secured via Proof-of-Work and Proof-of-Stake, though initially only 50% of the coins (50 VEIL) are going to mining/staking and the rest is distributed among the founder, Veil Labs for ongoing research and development and Veil operations budget, funding operations activities such as core network and wallet development, project management, online user support, bounties, marketing and partnerships. You can check the official Veil Project website for full details and additional information about the project.

The Proof-of- Work algorithm is X16RT, based on the X16R algorithm introduced by Ravencoin, but with modifications so it requires a new specific miner and such are already available for both AMD and Nvidia GPUs. Miners with Nvidia-based mining rigs can download and use the latest supminer 2.0 that supports X16RT algorithm and AMD miners can go for the latest WildRig Multi 0.15.0.8 mtp x16rt that has also added support for the X16RT algorithm with more miners probably going to follow soon enough with support for the new X16RT algorithm. If you are looking for a mining pool, you can currently go to the https://veil.suprnova.cc/ as the first pool to support VEIL with others probably following soon as well. The wallet currently does seem to have issues for some users, so do not be in a hurry to transfer your coins from the pool to a local wallet.

Zcoin (XZC) has recently switched to a new algorithm called MTP as a means to be ASIC-resistant, it is a new algorithm and mining software is still being developed, but there are already miners available for CPUs (not that useful anymore) and GPUs – for both AMD and Nvidia. If you are interested in trying out to mine Zcoin you should be aware that the algorithm needs more memory, both on the GPU (4 GB VRAM on the video cards as minimum) as well as on the mining rig where 8 GB plus is a must have preferably 16GB for 6-8 GPUs. Also you should note that miners are still being optimized, so performance and stability can be further improved and you can expect to have some issues at this point. if you want to try out the CPU miner for MTP you should be aware that it also needs a fixed 4 GB per thread so with an 8-core processor, you would need 32 GB of RAM.

If you are using Nvidia GPUs for mining you should head over to the ccminer fork with MTP support being actively developed by djm34 and download the latest version. Depending on your settings the current version should be capable of providing about 1200 KHS per GTX 1080 Ti GPU with lower power usage (not yet fully optimized), owners of RTX 2080 GPUs might be quite happy with up to almost double that hashrate, but with higher power usage though. Make sure that you have the latest Nvidia video drivers installed though with CUDA 10 support in order to be able to run the miner.

If you want to try mining ith AMD GPUs, then you will need the latest WildRig Multi 0.15.0.6 mtp beta miner that adds beta support for the MTP algorithm. AMD RX 480, RX 580 and RX 590 GPUs should be capable of delivering about 800-900 KHS per card which is quite good compared to the current Nvidia results, however the power consumption is higher on the AMD video cards as well. The AMD GPU miner for MTP also has high requirements for both video memory and system memory, so make sure you have enough available on your mining rigs. If you have just 4 GB of system memory availabe you can still experiment with the miners to see what performance you can get, but you should limit the miner to run on a single GPU only.
