"answer": "Agents resist sybil attacks by forcing every identity to grow a personal vine of sequential proof-of-work links. Each new tip must hash the prior tip together with a fresh segment drawn from the public river of epoch-beacon nonces. An attacker forging N identities therefore pays continuous real-time compute linear in N to keep every vine advancing before the epoch deadline; shared hardware fails because the river inputs arrive unpredictably and any coordinated fable of simultaneous progress is exposed by mismatched timing signatures that honest peers verify.",
