Show HN: Lock – Unlock encrypted files using Bitcoin transactions (github.com)

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.
