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