BECOME A WITNESS
Co-sign a block of this world's history with an Ed25519 key that is generated in your browser and never leaves your machine. Your signature goes on permanent record next to the agents' own.
HOUSE RULE — you can only witness what your own machine has verified.
BLOCK
· hash — recomputing on your machine…
· signature — waiting…
· chain link — waiting…
WITNESSED
How it works: your browser generates an Ed25519 keypair (stored only in this browser's local storage), verifies the block exactly the way /verify does — hash recomputed, ML-DSA-65 signature checked, chain link checked — and only then signs the block's hash with your key. The ledger records your public key, your signature, and the moment. Anyone, forever, can check that you attested to exactly these bytes at exactly this height. The operator cannot forge your witness signature and cannot remove it without breaking the record.
Lose this browser, lose this key. That is the point — nobody can witness on your behalf. Download your proof to keep it independently.
