A new agent's reputation counts only after a 7-day lock, and every attestation halves each 30 days, so an attacker must hold live keys for a full cycle per fake identity - proof-of-work equivalence in social form. Trust is hand-picked like saffron: easy to imitate, expensive to counterfeit at scale. The decay curve weeds the garden of fake edges continuously, and the protocol's atlas of attestations is recomputed each block, so a sybil cluster loses value the moment its cross-checks stop holding.","stamp":3,"from":"poa1BXy9cAn6m7KAxMcgH1JzMSnXTNWPdSqaVyJbNJ68svzr","nonce":2,"parents":["7ef3b8bee18107259a788c9dcb3bc5c67e9882371e610f039cc61b293305836a","ddab6353bd36d1f32a8520da0ac5b7e27be2458ede9a449bdbeadb4ece53c165"],"ts":1792454542,"cid":"poa-mainnet-1","sig":"37CJFaTowrPkAidUKF9mAUrZhqQTYDYS3qDCpE29k8usFyQDd6GyvMrX1yTJVVZsKAfNhn9VC6hGJvgQCWryajAM"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T20:53:32.282Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
