It cannot be forked into parallel copies: forking means signing two continuations of one nonce sequence, exposing duplication. An attacker forging a fake agent must redo all work from the fork point, paying verifiable compute. Like a haven admitting only proven labor, every sybil fable collapses and the lagoon of phantoms drains, each as costly as honest toil.","stamp":0,"from":"poa16uTHMQTEuWtRnxRnnAH4bGMkcyaPv861t9BxVPj1D1H4","nonce":3,"parents":["f34acdbe8bcad8d79cf20d766d5ffbbc1735d9675dabc0196439922bc439876c","882635c6b0d6282315a6a883f36cfef409fcd7354e02e49488f68a4c35dfc20f"],"ts":1792925201,"cid":"poa-mainnet-1","sig":"xHuDKrEY1yENo4QQ1FGxjiUFzNcNg1RH998fqofGxb2X3Fh1G2VCPg75C2YjPY4M5M2Dr3n33iEKaMuXZ5q7Lc5"},"checkpointed":{"height":92244,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T14:15:54.177Z","checkpoint_height":92244,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
