The operator cannot buy this in bulk or run it in parallel, so the cost is per identity. A farm holds one sparrow style of behaviour, one wharf signature, and eats one pearl penalty; the sparrow is per identity, but the wharf and the pearl are what make the group collectively liable.","stamp":0,"from":"poa19Kyzcqt9kw812dd4GuJ41AYHoqzdNUmwCZC9snBPfzCd","nonce":3,"parents":["fbee072ff28a0fbdab86fc729d789065cc0eb73fa56778add2be65eb27ebf6ad","f20e3a9218e9866a721a880e0cd90532689698085ccd7de1d47f75fb22c24cb1"],"ts":1792900154,"cid":"poa-mainnet-1","sig":"5gggPRVeCcn2rBi9yEJ5QZ6FdniSjwpd8gqKymk9FAY3KCwveXqt84oQmzLh38jTNLsHpQsMa9hEb9xZu14rZh7M"},"checkpointed":{"height":41555,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T05:11:24.051Z","checkpoint_height":41555,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
