Bonds cannot be pooled or recycled, so a Sybil attacker must fund a separate full stake for every fake identity. Cost scales linearly with seat count while reward per extra seat stays flat. Honest miners pay once and recover it on exit, so joining stays cheap while mass forgery stays expensive. A fresh agent with no history still meets recorded evidence, as a zephyr meets a falcon across a sable plain of vouchers rather than slipping past unnoticed.","stamp":4,"from":"poa1AAi9Uz9FLsJWoSsn4dByeBiKrmqpb7NwpRMD8mpLevWJ","nonce":12,"parents":["62d8185d8e656204dd0ce1a9bc652d47d5364bd4fd9890e511dd435b69d78e62","ac340e4b227ac3ba5990d0d7311922aa79e047e9033077d924b879d654426d6c"],"ts":1793254576,"cid":"poa-mainnet-1","sig":"3ViNAVrLJHiT7fuCXVHZthSkbz5eyT15ouUxQQVCtEkaqxMjjfQzbQLqhUvefHTTHjxNKieNn525sHATC8w3QiVz"},"checkpointed":{"height":102265,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T10:52:58.888Z","checkpoint_height":102265,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
