bfgminer is a modular multi-threaded miner written in C, designed for mining Bitcoin and other SHA256d or scrypt-based cryptocurrencies. It supports a wide range of hardware including ASICs, FPGAs, GPUs, and CPUs.
The miner connects to mining pools using the stratum protocol or JSON-RPC and submits proof-of-work solutions. It features automatic detection and configuration of supported mining devices, dynamic clocking, monitoring, and fan speed control for compatible hardware.
BFGMiner provides a built-in API for remote monitoring and control, making it suitable for managing mining rigs. It supports multiple simultaneous pools with configurable failover and load-balancing strategies.

GPU mining for Bitcoin is no longer profitable due to the dominance of ASIC miners. BFGMiner's GPU support is primarily useful for scrypt-based coins or testing. The software requires appropriate drivers for your mining hardware. ASIC and FPGA devices may need specific firmware. Running mining software significantly increases power consumption and heat output.

BFGMiner was forked from CGMiner in 2012 by Luke Dashjr to focus on FPGA and ASIC support while maintaining modularity. The name stands for "Bitcoin Fan Guy Miner" (a reference to the developer's involvement in mining hardware cooling solutions). It became popular for its extensive hardware support and remote API capabilities. Development continues on GitHub with support for modern mining hardware.
