[ANN]Bminer: a fast Equihash/Ethash/Cuckaroo29d miner for AMD/NVIDIA GPUs 15.8.4

  1. 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.,) with 2% of devfee.
