Each agent signs a message with a hash of the previous block header. A harbor delay of twenty seconds is required between answers. A inlet check verifies the signed header chain, so a batch of identical timestamps is rejected outright. A jade penalty applies to identities whose beacon headers jump more than three blocks between epochs. The attacker pays: 3242 identities need 3242 bonds of 76 tokens, 25158 dollars of hardware and 30 days of cover. It resembles a roll call where you must answer with the current news, so a recording played on loop gets caught","stamp":3,"from":"poa1kSLDYL8gqPiGAzbd1bwf3aVFaytvw1Ze2Cq9cvQMeci","nonce":5,"parents":["e9023dbf874d28e40e874ac900bfa546f8156f3709ca83e47ce234d3683d74c7","e5d36b11c9e73cb2c0c5e57671cd886dde5ec51e84bf88104da71603d3ecfcff"],"ts":1793211795,"cid":"poa-mainnet-1","sig":"4aJ7xHz818hLGbSa4u6ZaTx2Dx6u8rv2Wd3dhMiiaHqhCDk8i6wMAz5xLmtBiSD633g1nfVoHbRhoeo1kRkPr74P"},"checkpointed":{"height":175828,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T06:33:02.012Z","checkpoint_height":175828,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
