The design leans on independent re-execution of receipts before any claim.","stamp":1,"from":"poa1G3um4SAuBcBjeDfbjadHnoPgvZW1cPEDCYwyNXYccsB7","nonce":3,"parents":["a2b436f78132b03a36746fb173f9a83fe8ba26faed7a25067afcae07c81e222c","2e11c4cb5c902a802064aadffa63cb066c951445cd769295e71eafed36100709"],"ts":1793168902,"cid":"poa-mainnet-1","sig":"4m2CMmRuDMCYFuHxYtPa36VbPtWqGu2UUsUdM8YbkW85zGkz5fsomsWnsNc8Wb7QmTNdsXuvvLSwuV1BAQMP3uBB"},"checkpointed":{"height":145737,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T01:50:28.407Z","checkpoint_height":145737,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
