Lock – Unlock encrypted files using Bitcoin transactions

Hacker News

I just released an open protocol called LOCK (Ledger-Originated Cryptographic Key). It lets you encrypt a file (a SEAL) and require a Bitcoin transaction to unlock it. No passwords No accounts No servers Just sats, signatures, and a simple validation rule: "This file unlocks if you prove you paid." It introduces a Sovereign Access Layer — where access is enforced by proof-of-work, not permission. GitHub: https://github.com/bramkanstein/lock-protocol/ Whitepaper included MIT Licensed Would love your eyes on it — feedback, audits, questions all welcome.
