Open source Bitcoin solo mining pool with native Stratum V2 (Noise), released under GPLv3

I released the source for mkpool, a Bitcoin solo mining pool engine, under GPLv3.

The idea is straightforward. You mine with your own Bitcoin address as the username, and if you find a block the reward goes to you directly from the network. There is no custodial wallet in the middle.

What might interest this sub specifically is the protocol support. It speaks classic Stratum, Stratum over TLS, and native Stratum V2 with the Noise handshake, so mining traffic can be encrypted end to end. Work is always built from the full transaction set the node provides.

Because it is open source, the parts that matter to a miner, how shares are validated and how the coinbase and block are constructed, are all auditable rather than a black box.

It is licensed GPLv3 and was written from scratch in modern C++, inspired by Con Kolivas' ckpool.

Questions and code review welcome.
