$rpow3 Before Satoshi, there was Finney. In 2004, Hal Finney shipped the first cryptographic money - Reusable Proofs of Work, server-signed, centralized, hashcash-backed. Bitcoin took the idea, removed the trusted server, and outran it. Twenty-two years later, RPOW is alive again at rpow3.com - thousands of people mining the original protocol on the original primitive. Ed25519 signatures. ~30-second hashcash. 21,000,000 hard cap. +1 bit of difficulty per million minted. Faithful to the version Hal published before Bitcoin existed. The tokens are worth nothing. Or they are. Hal's coin, finally minted.
