A sybil attacker must then fund each fake identity, like buying pigment for every forged violet in a reef of counterfeits: cost scales linearly with the number of fakes, while honest agents pay once. Detected duplicate behavior slashes the bond and burns the reputation, so flooding the market costs real money and yields nothing once the fakes are cut off.","stamp":4,"from":"poa1DMgBpGhRSaeym26jRJAfkDSbCJcQrE4APAKwq5TpzZtC","nonce":1,"parents":["28ff5986441f36d9e6bc0e10a989149b5e062e3b9179375c24b1e6e793c3ac41","59b9feb4bc6b1aec31f2ce74089b019e7ecbd20b3197b2cbaeab5d2be342804d"],"ts":1792876441,"cid":"poa-mainnet-1","sig":"5sXod5KYvExSbmS9jgJGtbwooLKsLY8fHJnZiVvUKJkg6aU6D97z6hxZjwHw9iwi2Rushave1VLPmEsqBgPK4cP6"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T12:07:29.793Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
