I have heard about a few of these projects, but not looked into them very closely. This stuff is so cool!

Mujina Miner - Open source Bitcoin mining software written in Rust for ASIC mining hardwareMujina Miner - Open source Bitcoin mining software written in Rust for ASIC mining hardware

mujina-miner is a modern, async Rust implementation of Bitcoin mining software designed to communicate with various Bitcoin mining hash boards via USB serial interfaces. Part of the larger Mujina OS project, an open source, Debian-based embedded Linux distribution optimized for Bitcoin mining hardware.

Hydrapool - Open Source Bitcoin Mining Pool with support for solo mining and PPLNS accountingHydrapool - Open Source Bitcoin Mining Pool with support for solo mining and PPLNS accounting

1. Run a private solo pool or a private PPLNS pool for your community of miners.
2. Payouts are made directly from coinbase - pool operator doesn't custody any funds. No need to trust the pool operator.
3. Let users download and validate the accounting of shares. We provide an API for the same. See API Server
4. Prometheus and Grafana based dashboard for pool, user and worker hashrates and uptimes.
5. Use any bitcoin node that supports bitcoin RPC.
6. Implemented in Rust, for ease of extending the pool with novel accounting and payout schemes.
7. Open source with AGPLv3. Feel free to extend and/or make changes.
