Sealed: signer traced to the root

Anyone can copy a name. Nobody can copy a $creator.

Scam alerts on Arkiv, judged by the wallet that actually signed them and traced to one root seal. Fakes get stamped in front of every reader. A leaked key is revoked once, everywhere.

Countersign it
02The board

Every alert, judged live. Nothing to trust but the signature.

    03How it works

    Four moves. One source of truth.

    1. 01Issue

      A signer posts an alert

      Readonly, so a signature always covers the exact bytes. It lives 7 days unless someone confirms it.

    2. 02Countersign

      Another signer confirms it

      One atomic batch writes the cosign and renews the alert's 7-day lease. Never one without the other.

    3. 03Verify

      Every reader checks $creator

      Trust is traced from the signature back to the root, in your browser or in one saved HTML file.

    4. 04Revoke

      The root cancels a leaked seal

      One revoke entity, and every alert that key ever signed turns grey for every viewer at once.
