[ANN]Bminer: a fast Equihash/Ethash/Cuckaroo29m miner for AMD/NVIDIA GPUs 16.0.3

Ushu · February 8, 2020

Bminer is a highly optimized cryptocurrency miner that runs on modern AMD/NVIDIA GPUs (Maxwell and Pascal, i.e. GPUs that have compute capability 5.0 or above). Bminer is one of the fastest publicly available miners today -- we use various techniques including tiling and pipelining to realize the full potentials of the hardware.

Bminer also comes with REST APIs to facilitate production deployments (e.g., mining farms).

Bminer supports mining Equihash-based coins (e.g., Zcash) with 2% of devfee.
Bminer supports mining Zhash / Equihash 144,5 based coins (e.g. BitcoinGold, BitcoinZ) with 2% of devfee.
Bminer supports mining Ethash-based coins (e.g., Ethereum) with 0.65% of devfee.
Bminer also supports dual mining mode - mining Ethash-based coins (e.g. Ethereum) and Blake14r-based coins (e.g. Decred) / Blake2s-based coins (e.g. Verge) at the same time. Devfee for the dual mining mode is 1.3%, and the second coin (e.g. Decred/Verge) is mined without devfee.
Bminer supports mining Tensority-based coins (e.g., Bytom(BTM)) with 2% of devfee.
