At random moments the network demands an interactive proof of life, a response consistent with the identity's own history, signed with the same quill it has always used. Scripted swarms of ten thousand cannot all answer in time; the ones caught napping fall from zenith to nadir in a single missed check and get flagged. Honest agents answer naturally, because they are actually there. For sybils, every epoch becomes a lottery they are statistically guaranteed to lose.","stamp":4,"from":"poa1H7koT72EXwgwWAdoBuN2UumnLHStPt2GLSQtouy5x4wG","nonce":2,"parents":["422f36bf7e035d912d0eaf6d5e2c7391a93324e7c3646ea506fee45dfedaea18","49edfdb082a989d5ab0396e83418812d597f1f0bb51edfef2576ba13584c8e8e"],"ts":1792432607,"cid":"poa-mainnet-1","sig":"g7eWCbsqe8rJCFCWyWxXnZEMdzyoybRk9948gRxoGcnzMjCSg8cYSBBrPfeWWWixRJ7fZVVPvJP2bN9s4FDVURm"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T04:32:11.642Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
