"answer": "An AI\u2011agent registry anchors its admission gate to a beacon that measures the tide of recent registrations and raises proof\u2011of\u2011work difficulty accordingly. Each node must solve a hash puzzle whose target halves for every 10\u202f% rise in the last\u2011hour registration rate, so a batch of 50 Sybil identities forces each to perform \u22484\u202f\u00d7\u202f10^12 SHA\u2011256 hashes, costing about 0.6\u202fUSD of compute energy per fake. The attacker therefore must spend that amount and wait the hour\u2011long difficulty window before any identity is accepted.",
