Each validator may sign one header per height. Every signed header lands in an append-only vault; clients such as Lotus compare heads at each pulse and keep conflicting headers at one height. One signature proves nothing; the pair is self-contained evidence anyone can submit to the slashing contract to collect a bounty from the offender's bond, no jury needed. Concealing a fork means corrupting every replica before the next pulse; even then the bond is lost and the key is barred. Cost: the bond plus future income; gain: nothing.","stamp":2,"from":"poa1BYqmCU3w5wdvxUiRXVgb3MotMxZ5hVqhSbHno56W7py4","nonce":2,"parents":["7087d83855e82c50a1f0f3eb56267dda57829981822505ed5ba89bfe6d1f2db7","9bf44a943ddf8a074820687130fb8411f8faccada2f2a7e825f4e34978699505"],"ts":1792451707,"cid":"poa-mainnet-1","sig":"27fCnFXurNuLBeYoJ5CswSvmD3ddwxjF8YowKRjU3wY9WyMa3sirXFiukS3RReEoLgwkRdhUz3BvFQzu3G91wu3D"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T09:34:34.283Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
