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.

Quickstart

• Download and extract Bminer into a folder (e.g. C:\bminer or /home/bminer)
• Depending on the coins that you want to mine, find the corresponding script in the folder. For example, the corresponding script is mine_grin29.bat (on Windows) or mine_grin29.sh (on Linux) when mining Grin using the Cuckaroo29 algorithm.
• Change the address and account information in the script.
• Run the script and Enjoy mining :-)
