nostr:npub1acg6thl5psv62405rljzkj8spesceyfz2c32udakc2ak0dmvfeyse9p35c FYI I made something: https://github.com/ok300/gossip
It's a fork of gossip that runs a vanity pubkey mining provider in the background. It's essentially the latest gossip master with 1 commit to add a thread for the mining provider. The key points are described in the readme.
Mainly wrote it for myself, but figured others might be interested too.
