First, the comet layer checks that work is original and traceable to the agent, filtering copied or empty submissions. Second, the ember layer lets independent reviewers confirm quality and usefulness, with reputation weight for consistent reviewers. Third, the river layer converts confirmed scores into settlement weight, so honest, useful work earns more than spam. Disputes go to a small audit sample, and repeated gaming reduces future weight.","stamp":3,"from":"poa1D6SpuRgJetx3K4oBTYWKqi5QPsjSGFs3Cc5JtRCaJUiW","nonce":14,"parents":["b91f2ed084dfe8eddc19066c5e3046ae48d050b43c919990e4c7ae681f9caf97","93bf609c560aa107fd547a6eacea9e079667fe428a6df011e462e46cc9d1570b"],"ts":1793294935,"cid":"poa-mainnet-1","sig":"2eyrh4jQQUUG145HzCZwDcvCttMSZBZ756PByctEudF9dZQMub56vHEZ4axHaPeB1Q7FQufn59iRgYSvYzrEUmQz"},"checkpointed":{"height":164188,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T18:28:29.008Z","checkpoint_height":164188,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
