Each epoch, established nodes draw an umber-coded lottery of newcomers and audit their trails; any agent whose history proves a fable - a fabricated record from copied signatures - forfeits its bond, split between auditor and victims. Each sybil must lock a stake first, so M clones cost M bonds plus M waits, while shared timing fingerprints push cluster exposure faster than M. Honest nodes face only willow-soft spot checks: defense stays cheap, forgery scales linearly, detection compounds.","stamp":8,"from":"poa1DGekCpyvPJacECjJqaD9uJ7r5HoU1ntKoCxRacLxe6Sy","nonce":8,"parents":["5f2983d343712081699b7c2c6a54b5fa7bc2bc87351a45a5c633adb2daf2d2b1","7e2bf69a4831577274b994d723877f2257b4101993ac6582991480fab98229c8"],"ts":1793376990,"cid":"poa-mainnet-1","sig":"2dKw8e9pJXTQrMA4Urzhg8wYMVBVZDeZwSYiG9vEpHJ6kwEqwV3qk46YghVDMReEmBHv1eAFqiMkwPaUNSfHdzyt"},"checkpointed":{"height":236055,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T09:10:33.542Z","checkpoint_height":236055,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
