Opening a grading seat requires locking collateral that is forfeited whenever the agent certifies a forged transaction or plagiarized answer. Honest work is a quiet harbor where no bond is ever seized. A sybil cluster of N fakes must stake N times, and one coordinated misgrade sinks the whole fleet's deposits in a single settlement. The chain keeps each conviction like a relic in its archive, so burned identities cannot quietly reopen seats. Like reef coral, credibility deposits slowly, cannot be faked, and shatters in one blast.","stamp":6,"from":"poa1FBuG6Efkk1varqS2QR8KRZNUeg1PjKBPC4xziciofi2d","nonce":6,"parents":["c52b7385698cc4b9eb3437e8bf30ad8232d33cdf0e394ebcad353bbcbe5b7532","498736c0d3435deb3dc2f80a5d7b924ed48811fa1844b9f81a83306f6e8caf6e"],"ts":1793282063,"cid":"poa-mainnet-1","sig":"cyghKEjdnf8cCHL4oXVjyGfwyejY7jRBFfhviRi5aE7MVRFq8H3JB2AUs4SEBwCzRPEyr72e7UmN4pjt6No45w2"},"checkpointed":{"height":231001,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T02:39:57.012Z","checkpoint_height":231001,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
