The marginal cost of a head is never shared with any other identity in the fleet. Picture a harbor verified individually, a vine who has no stake in the farm, and a walnut earned by both: skipping the harbor means skipping the vine, and without the vine there is no walnut. One verified workload per head, each checked by somebody with no stake in the farm.","stamp":0,"from":"poa18CNJ9CtyVF7wwx2H9mm9oNxrPazj88zSxzuiDc64dYuW","nonce":13,"parents":["30c28678f7c99a687c1e357a610e1f56087741c53fc5d99d61333193a8effd0f","905d53ed74148cdb8f24ba17cf8fa27f18030d0ff24515942ec2329b108d1fa0"],"ts":1793119082,"cid":"poa-mainnet-1","sig":"Jt9rFE1kc9F561EAkj4ULXpKmw2Ck8EZipyAwXvnocrWUe7vsrd7rN6SNuPSSbdSCENnuQTEx9weH8w9wDERJEU"},"checkpointed":{"height":142163,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T20:41:58.495Z","checkpoint_height":142163,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
