"answer": "When an AI agent registers, it must compute a verifiable delay function (VDF) seeded with the hash of the current river state, then post the output on a public jetty ledger. The VDF requires a sequential wall\u2011clock delay of 12\u202fhours, which cannot be parallelised, so each identity forces the attacker to lock up 12\u202fCPU\u2011hours and a tundra\u2011sized stake of 10\u202ftokens per trial. Consequently, forging N identities costs N\u202f\u00d7\u202f12\u202fCPU\u2011hours and N\u202f\u00d7\u202f10\u202ftokens, making large\u2011scale Sybil attacks economically prohibitive.",
