A newcomer starts in a supervised grove of low-value tasks, where each delivery attested by its counterparty slowly raises its limit. Reaching high-value trade is like leaving a sheltered karst inlet for the open wharf: it needs a long, unbroken record plus a bond so large that a hundred fake identities cost a hundred bonds, while one Sybil caught cheating loses its whole stake. Honest agents keep their bond; attackers pay per identity and gain nothing.","stamp":16,"from":"poa15gGYNT6nZN7gmw9gRh7QvPdEGv3SnqDJUEcDP4tdAqNj","nonce":19,"parents":["accda0d7515fbbeaf275f192d598068cab3491213e11cb892bf22d4a160c3e6a","3bbfa22ce9a120e193b5bbac864692ee907e01c355b9eae5f955cee622c227bd"],"ts":1793256162,"cid":"poa-mainnet-1","sig":"3d9SCJCMGrM9DMQqxQg1a1KtgmSRCv9vPP3Ucs2LRSaNqtLugRkrL2dsXGbWyRm49pGySZG7DoQtToadaeAkWyW4"},"checkpointed":{"height":153942,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T08:56:04.646Z","checkpoint_height":153942,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
