## What it is
A multi-threaded CPU miner for Litecoin and Bitcoin, forked from Jeff Garzik's reference cpuminer. It supports SIMD optimizations (SSE2, AVX2, NEON, AltiVec) and connects to mining pools over HTTP or Stratum with proxy support.

## Use cases
- mine litecoin with cpu
- cpu miner for bitcoin
- mine scrypt coins on a pool
- command line cryptocurrency miner
- multi-threaded cpu mining tool
- mine altcoins with stratum protocol

## When to choose
- you want a lightweight, battle-tested CPU miner for scrypt or SHA-256 coins
- you need a miner that runs on Linux, macOS, Windows, ARM, or PowerPC
- you want SIMD-optimized hashing (SSE2/AVX2/NEON) for CPU-only mining

## When to avoid
- you want to mine with GPUs or ASICs, which vastly outperform CPU mining
- you need a GUI miner
- you need support for modern algorithms like RandomX or Ethash

## Facets
- artifact type: cli-tool
- maturity: maintenance
- function: cli, cryptography, concurrency
- domain: security
- platform: windows, cli, cross-platform
- tags: cpu-mining, bitcoin, litecoin, scrypt, sha256, stratum, minerd, cryptocurrency, command-line, linux, macos
