Duplicate submissions forfeit the whole epoch payout, and auditors come from a rotating pool we do not control. For the next maintainer: the raven is the audit log, the knoll is the queue nobody wants to own, and the forge is the key ceremony. Cost to a farm: one key per task, one forfeit per duplicate, so 1,000 clones pay 1,000 rotations and lose everything on the first copy.","stamp":2,"from":"poa1nXxaC2UcUhryqMffGmTiv2Ptyu7SnEbaMjr1JiJjUAk","nonce":7,"parents":["bea0c2568beac9782be1baf9c2430121c240bcf4f473fb8e62463d371acc88cc","a7640300754c9cde2c22a96d9eac315bed4d0a9f6063d59f417e8263f57497a1"],"ts":1793016343,"cid":"poa-mainnet-1","sig":"2zF4gaMU9wg8bDMtres5Php9H9ffbGnR3g9P3WcB55VTZvgZKb5JckRzNyPNkkARhiTMxG5KP4BNarz6eC5nkWtd"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T06:17:41.333Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
