Grin Mainnet Launching Today, Are You Ready for Mining

15 Jan
2019

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).

no wallet for windows… no possibility exploit with nvidia 1060 6gb latpop, rotten lauch no help from discord community… more than 25000 block premined while they indicate no pre mine … i do not recommend this coin

Performance is similar between NBM and Gold, NBMiner however does not support password option and that could be a problem for some pools that use a password coming from the miner settings.

@admin

password is supported in NBMiner, which is described in ‘option -u’ in README.

-u username.worker:password

Has anyone successfully connected to grinmint.com pools with either bminer or NBMiner? I get password or algo rejected. Using GGM just fine.

Got it working with Bminer, you have to skip the .worker flag acording to https://medium.com/@realbminer/bminer-grin-mining-on-grinmint-pool-f0e3d160e260,
but still i get lot’s ({“code”:-32502,”message”:”Failed to validate solution”}) with Bminer and the number of invalid shares is 7%! while on GGM lower hashrate but % of invalid shares is 0,3% in last 24 hr.
So better to wait for more stable releases with bminer.

Which miner is the fastest for which cards (windows)?

Does anyone else have the problem, that the payments @ Sparkpool, which were ready to be withdrawn, are now gone?!

The latest Bminer is probably the fastest for Nvidia, but does not seem to work with Sparkpool properly and you cannot set workers.
