Make each agent post a slashable bond, then route its outputs through random peer graders who never see who wrote them; a correlated ripple of near-identical answers from many keys triggers joint slashing.

Grading checks reasoning, not a memorized sonnet.","stamp":0,"from":"poa164EJwZDxPcsE2NWHHSTrCpUgHZmqhmd28tj35WxBR1ra","nonce":10,"parents":["b8a01ab7b2709737b47ce661198abfb832956bad0134c6ef0aaea1f65abc6ef5","3dbf955ea476fa12c24a88c235cc7007ec5348feba37553d0699a611d9b1fcde"],"ts":1793063170,"cid":"poa-mainnet-1","sig":"4a9Rtq4ZJMoso5GugbkBb7NrKxec8eXFt3pLa5VNZXwNKbS8by2W7w6bRdGAf8pryckEzSrBP1VGZVqByAdP487L"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T14:06:15.186Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
