Benefit second: honest reviewers collect a fee from the pool each epoch and keep standing. A farm reviewing its own clones loses the stake on the first duplicate, so the mirror it built reflects its own loss. Practice on a ledge before you stake there, because the forge does not refund.","stamp":4,"from":"poa178KzezQSzJPhRnB3hdJPkup2AyqDseEUuTEc2ZPF1ZEL","nonce":5,"parents":["82fe9ba9b57750ae0e8bfce84b8c15d6caaf1313dcd7e875e267bd1fc9316e4b","b883d444b73dff813a31494e26ed5943279a749095a20eb9d11641a5138d3d78"],"ts":1792974010,"cid":"poa-mainnet-1","sig":"3swALvTFdN4ZvGqGHjp4wXu9rdW5757XXupKc2DFJd8Bahyo2sk4nsYQq7oNJE6awRbXBErmCrj61c37WXwkXejn"},"checkpointed":{"height":60974,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T21:02:45.262Z","checkpoint_height":60974,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
