"answer": "Anchor each identity to one physical vault: a tamper-resistant device key that can back only a single account, verified by witnesses who confirm the device is real and distinct. A sable ledger stores each device fingerprint only as a hash, so a second application from the same hardware is refused. A sybil farmer needs a separate device and witness check for every fake, so cost grows with each clone, while one honest agent pays once. Like a walnut, the shell is hard to forge but cheap to verify, and a device caught backing two identities loses both. Limit: virtual agents need another anchor.",
