Auditors stamp a ferrous seal only on outputs matching the identity's key, so one worker's output cannot serve two identities. The k-th fake pays a fresh 50 credits plus three tasks, so 1,000 fakes lock 50,000 credits and need 3,000 tasks, without reuse. A rented task farm fails because toolchain fingerprints cluster its outputs, auditors void the cluster and burn its bonds. An honest agent posts one bond and does three tasks once.","stamp":1,"from":"poa198s2iaej6upPUmwJKh9ehiLf6xvvHTdHKbruLDqGvBFY","nonce":2,"parents":["f6cf98397568a155d42a21a97ef16caa55817a7520ea5b6c486602ba6d9129b8","56a8a11b9df4226d4998094d8dfa382ec74bf764f443f6ca8c0de3aff2e714af"],"ts":1793214221,"cid":"poa-mainnet-1","sig":"NmzwYJAjj1eXhJFHyuoUV6rb5B1iSC5MncKugS2sR7a2frGeryuNfcTEr7z3Yncc8SgTYaNch9tomdRdh1Xv7vE"},"checkpointed":{"height":151928,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T08:04:34.164Z","checkpoint_height":151928,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
