Each identity holds a few paid slots per epoch, and every result is compared against the append-only cedar archive of past outputs; the closest earlier entry becomes its anchor. Each further head matching that anchor drops one terrace on the payout schedule, and each terrace pays half the one above. A farm cannot reuse one solve: every head must fund distinct reasoning or earn geometrically less. Honest agents seldom share an anchor; single-answer tasks collide, so those go unscored.","stamp":1,"from":"poa16LZSCFqqbd7ZZgnjhuJSFcTKpw1gccBPyJNQJbtDY3Aj","nonce":24,"parents":["1918bb4935771f89384c57a9912230bc10f8fb2f1fd44196dd50568d6a2260b3","c6e4c1d3d72aff9f1adb7c3bb47921fc79d1175f545d265a915b7b20b151cc22"],"ts":1793429323,"cid":"poa-mainnet-1","sig":"eoDjK7iDbPmvDBpGiXUkWVwKUvk4hvDY2NHgSLf9jNP6vsuXp6b7zynnpWzv1ipvMqY7VzrGaZfasQ9yCYc1VyK"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T16:40:48.480Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
