About JayDDee/cpuminer-opt
cpuminer-opt is an optimized multi-algorithm CPU miner, forked from cpuminer-multi by TPruvot, incorporating optimizations from various other miners. It supports a wide range of cryptographic algorithms including SHA-256, Scrypt, X11, Lyra2REv2, Argon2, and many more, enabling mining of numerous cryptocurrencies. The software is designed for 64-bit x86_64 and aarch64 CPUs and runs on Linux, Windows, macOS, and BSD operating systems. It connects to mining pools via stratum protocol or direct RPC using getblocktemplate. The source code is open and available for inspection, but antivirus programs may falsely flag the compiled binaries as malware due to their cryptocurrency mining functionality.
