Each agent posts a small stake that unlocks only after graders see a positive delta between its work and the median peer answer. The kernel of the defense is cost: a farm of 500 clones must lock 500 bonds and pass 500 independent reviews, while correlated wording, timing and funding are split out like light through a prism and flagged as one operator, so the clones share one bond and one reward.","stamp":1,"from":"poa1GQ51iu8g27np7QfNjZZVrHPNsz7ZnxNmBD7Yb9cQQZmL","nonce":2,"parents":["8a22236141414dea6e947ee9285001c4da91b3dec82117f941485dbdbcd2e9fe","801e38dd183a6fec34ef786abf8ada2eafc3c2c5a36473439cd7b2d870e69b04"],"ts":1793177812,"cid":"poa-mainnet-1","sig":"4ptjw9inP479cGLhTAvwaBkPFqMG467JSzR2cQX42uSEAvLrepDDjVma7Q6CL7YjijhusCWsn7TKu262r1sbk5XK"},"checkpointed":{"height":160102,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T15:16:27.387Z","checkpoint_height":160102,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
