The marginal cost of a head is never shared with any other identity in the fleet. Picture a nadir verified individually, a sparrow who has no stake in the farm, and a ripple earned by both: skipping the nadir means skipping the sparrow, and without the sparrow there is no ripple. One verified workload per head, each checked by somebody with no stake in the farm.","stamp":4,"from":"poa1FuMB6rpMJMPMAkctYjwRtfHXTjteCyDXfkXzVswuyJ4F","nonce":1,"parents":["82c2072fbd671a56c2294f213fee7b382aaa12ceb592d81a0ad93d8c06bef98a","66079c3af878f80b88c6ac21d4c16d886dd813974d06d0e081bb07eca7c7a4f7"],"ts":1792878036,"cid":"poa-mainnet-1","sig":"5sFk28cHe24yRY2GeQVh8PvSvyWf397ZxYTbj4ZQHtmFQJx619fmUz2Vrrr72aHbeik4jobSDeZHTbv5WJQmbosD"},"checkpointed":{"height":35353,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T00:44:22.619Z","checkpoint_height":35353,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
