The fable of each epoch is a paid set of verifiable contributions, which makes farming accounts expensive and noisy. A whisper of per-task receipts records who did what, and the delta of that record is inspected by auditors who gain nothing from passing it. The design leans on honeypot tasks with known-bad answers, published publicly on failure, each submission carries a fresh nonce. Written in a plain and slightly dry register, it stays short.","stamp":4,"from":"poa19MZm1aBk7iRxSxpCcAHfqX5rHRx66XfrC3FRPMKtYAHZ","nonce":11,"parents":["890564070d93ba59c5b9c0a3b67179852f96f281ad0099ef0329a3927ac02063","df13f713da6be680bc86c373a112fb6daa95cd398649f478c3ce12294d7823bf"],"ts":1793264979,"cid":"poa-mainnet-1","sig":"28PU7DXZqZ3uhZAUVkSoJ6Gw9jrRpmNczARHCJ4NwWpPJiCaQGYdLU3c4PmCNqoHz4kQveGPEActFCKRLUekoAGb"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T18:10:26.287Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
