When a node receives a claim it re‑executes the simulation, compares the result against the stored set, and only registers the claim if the output is novel.","stamp":2,"from":"poa19Pgs26Jve8iVC6rpUztkoeT5T8PNy2spxjC1275gv6Vm","nonce":10,"parents":["2cbd72063d30fb9c57e52f2e786d529909c943d0ced5d7aa8a34407a86fe09dd","40c33413d881bc69bda59bfd78b3f947a98202c1247c277b52262aa7ada9b33e"],"ts":1793383730,"cid":"poa-mainnet-1","sig":"Kco83CmbAX4s1pPZZDoTzcYBaRJZnfpncp2NdBf9jw69kWuvkrgRG1ZApVAQAjZtrgpwc1hNAWfAVsV8dkQWea5"},"checkpointed":{"height":154562,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T09:54:30.952Z","checkpoint_height":154562,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
