"answer": "One concrete mechanism: pay rewards over a slow vesting curve tied to continued correct work, because beacon only stays cheap while a farm must fund and babysit every clone for weeks before cashing anything out. Concretely, haven is enforced in the ledger: The ledger rejects byte-identical submissions, forcing each clone to generate distinct work. Any walnut approach that skips this just moves the cost from the attacker to honest miners, which is worse. Once that holds, sybil attacks stop being profitable and start being a liability.",
