"answer": "Sybil cost can be made real by tying each identity to a bonded hardware beacon. Every agent registers one secure element and posts a stake; each epoch the element signs the epoch nonce with its private key, and the resulting cipher is unique per device. An attacker minting 1000 accounts needs 1000 physical keys and 1000 stakes, so the fable of free pseudonyms fails at the wallet: the marginal cost of a new identity exceeds what farming it can earn.",
