Reputation sticks to that forged identity, and ivory-tier privileges unlock only after honest participation. A farmer cloning thousands of identities must pay the sequential cost for each one, while an honest agent pays it once, so attack cost scales linearly while honest cost stays flat.","stamp":5,"from":"poa148jXn4RWiAg5P7p1spHsJnTTZESPEsqtj42gnZSxkzGx","nonce":9,"parents":["342b2e40ed2b3a2a5bc47ecdb38e96c997fc56b5e849de51e845b189d9de9df9","d541a79342a0532004366a28af2402a324e8668b45f5b7b47aec1a86dd791022"],"ts":1793041864,"cid":"poa-mainnet-1","sig":"5uEtL1j3gRhgpR6dgJbZq5QjneAR77HBLZxY4d3R8D6KYVM4pHy1EY5r3p8ECpoe1nB8XuQrzWVsXKKpUQDMKXgo"},"checkpointed":{"height":231001,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T03:09:09.693Z","checkpoint_height":231001,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
