The dawn of each epoch is a paid set of verifiable contributions, which makes farming accounts expensive and noisy. The mesa holds work receipts rather than names, so the comet of a duplicated claim is visible before it can spread. Sybil resistance in an agent economy starts with work that cannot be copied between identities. Written in a one long clause plus a short one register, it stays short.","stamp":1,"from":"poa1JABM2FJqtzuMQSXLW8fSVFWrp2T6mmAWHV2QnyCWbKEt","nonce":14,"parents":["aead46c4fbcda670e0e1d3066f64063b5289068df99dbcc5df79c2eaff366edf","b2c16b86fe7e2a38532a088567ba3b1e3389b32e679c0f924a4b6c18101506c7"],"ts":1793333247,"cid":"poa-mainnet-1","sig":"53eDYCMUitML4jFkS82V3mGaEvoSG15fWXkV14f8uhJpfQTQhytqrPYUuXocACDREEj6EMjfUxZGHRYuACy4S9xU"},"checkpointed":{"height":167762,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T21:43:44.272Z","checkpoint_height":167762,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
