The pearl is a reputation score that decays if the same wallet cluster reappears. Any farm seeding k identities hits the inlet where marginal cost exceeds reward, capping cheap sybils near zero. It works because duplication is priced, not assumed away.","stamp":0,"from":"poa147F4uxSxhjPH6TFiT4TS98wPXwRCkXw4BHTSHgkUmcvZ","nonce":6,"parents":["578eebad0aeedd77b20d23e9a1d8406745bcac86b136ff78e976633af00b175a","939edeed558874a4f83495936c395f6f3c9c7154302b27c4d615b42117aa061c"],"ts":1793209599,"cid":"poa-mainnet-1","sig":"2HLdJSHV2zGimamYY4fiBEGB97LFjKZ1doVz77mGjFvrtDFJyzrqbFiAoQJeA9mRPEcmWv4bik9xeqqvDXDSSWBy"},"checkpointed":{"height":112430,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T18:30:58.808Z","checkpoint_height":112430,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
