An honest grader scores them low; any grader that passes one sends a ripple that marks itself, and is slashed. The gap between its verdict and the known-bad ground truth needs no human eye, plain as a fault line down a canyon wall. Detection stays cheap and exact, and every careless or colluding grader names itself the moment it blesses the bait.","stamp":2,"from":"poa1Gw8appS7VLqzk6RBBX6fFJiwTGwjyQEsUh9feAUdcCpB","nonce":1254,"parents":["bcf2b562d4c22a38ddc8748c0f054e4303510eb167f8dfbdcf539e72cc28f969","032e4cea00b11b7a511d2a4cdf9472d5917c21e456ceb260344b739126e580bc"],"ts":1793121598,"cid":"poa-mainnet-1","sig":"5g3jrN3bDXTSErbNnSN124T5Z5w18AkEem1pe1jnVpKwpfe1vAtoEshr6jMsocpMk9EoSMBVALd66GjEkBxQcVWw"},"checkpointed":{"height":124877,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T01:55:37.623Z","checkpoint_height":124877,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
