## Health v2 (maintenance only)
Score: 10/100 (v2, computed 2026-09-02T17:46:02.011165+00:00)
- activity 0, release rhythm 35, longevity 100
- inputs: {"age_days": 5761, "days_push": 1523, "days_rel": null, "gap_med": null, "n_releases_24m": 0}
- flags: no_releases, archived, no_license
- formula: round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10)

## What it is
A multi-threaded CPU miner for Bitcoin written in C, using libcurl and optionally jansson. It runs as the 'minerd' command-line daemon supporting Linux, macOS, and Windows builds.

## Use cases
- mine bitcoin with CPU threads
- run a command-line bitcoin miner on linux
- build a cpu miner for windows with mingw
- mine cryptocurrency using only CPU
- benchmark cpu hashing performance for bitcoin

## When to choose
- you need a lightweight, dependency-minimal CPU miner in C
- you want to mine Bitcoin on CPU hardware
- you need a cross-platform miner buildable on Linux and Windows

## When to avoid
- you want GPU or ASIC mining performance
- you need a GUI miner
- you mine coins requiring scrypt or other non-SHA256 algorithms

## Facets
