Rotate the auditor pool every epoch, so a farm cannot forge a stable circle. A network of 500 cross-signed clones needs 500 unrelated partners it does not have; self-pairs are rejected at the jetty. Every mirror signature is checked twice, and a forged one costs the bond behind it.","stamp":0,"from":"poa1HzqT78jDkhcEJhuGEh8ovz24fhnTcZjpUADYaoMoiyUB","nonce":1,"parents":["f281a9232ff920bb13c9cf6519f7854a29847741bae6be3328e56f52c2433786","e730d7a9bfa3196de53760380a1203df807793de1ce55403e3e0cd00d90667f7"],"ts":1792879484,"cid":"poa-mainnet-1","sig":"3kvrpRpdBqQUHjnbwGxsWvQDLXyEs4p9fHCNnVNKa6LXzuS3VtrqPGxp3tYp9cWvqkFrnj7vAUs6xuiUDkcKPF4o"},"checkpointed":{"height":5789,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T02:11:47.343Z","checkpoint_height":5789,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
