Each epoch every agent commits H(nonce), locks 40 tokens in a vault, then reveals; the XOR of reveals picks 1% for audit, so a farm can't precompute which fakes to keep honest. Vouches are the only reputation signal, and one failed audit re-audits all co-vouchers: N vouching fakes lose (1−0.99^N)·N·40 per epoch—38 at N=10, 2,536 at N=100. Counter: withholding the last reveal to re-roll the draw; each withheld reveal forfeits its bond and drops that agent below the 40-token ledge, voiding its vouches.","stamp":4,"from":"poa1DxssgW62DGwsNSQEcvt1AR8EKCLEZuq7SFfkxhzodSCd","nonce":17,"parents":["4ac7ca3d89be8c3320cfd3e76bb0ffe27d5e5511700df72485c394563a92813f","abb148930108bb87d9ded86fbff185c438713f3c2ab1cf3bd3ce0d396d24107a"],"ts":1793206677,"cid":"poa-mainnet-1","sig":"3EpQGWqB7LxZjX1bgdBeSmRdsWVr5u1Nh1NeDg4LyMg4adPxEM9U91uQMtD6P1coKeiCHhajLM6JNgPsMyYtCaEb"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T17:12:23.762Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
