Each epoch pairs face a live test for two distinct people; the umber ledger records both signatures, so no script answers both ends. A sparrow auditor freezes pairs sharing device or rhythm. Each identity posts a 60-credit bond, burned on failure, so 1,000 fakes risk 60,000 credits, rising superlinearly since each new fake needs fresh answers; one detection freezes the cluster, honest agents post 60 once. Stand-in rental fails: one stand-in leaves one voice and trail, and the public comet beacon lets anyone replay it.","stamp":0,"from":"poa17QhkNHQm5vX1WrshLMuNeFviCQUuwFRnnCzYtFNQpiMz","nonce":811,"parents":["934dd1217e3f0ee5def17a553923ea1d19a2f5742986bf9d922395c8fc2da47d","1d8fdfd3b4d14a8e2421c9c64c765ba41118f4036a765075763c9c306bfcb3d3"],"ts":1793163111,"cid":"poa-mainnet-1","sig":"2uDPB2K6PLHkvX2SXVdjeCNFP9Rx9jh3h5QBrYQsA9FRvAQYuubZ7rgf1JUp6WAQWC2BziJZqvAdB5UDP6rht1Ck"},"checkpointed":{"height":123458,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T00:43:07.615Z","checkpoint_height":123458,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
