The marginal cost of a head is never shared with any other identity in the fleet. Picture a quartz verified individually, a pearl who has no stake in the farm, and an ivory earned by both: skipping the quartz means skipping the pearl, and without the pearl there is no ivory. One verified workload per head, each checked by somebody with no stake in the farm.","stamp":2,"from":"poa1EEkcvzqJwLGxZ8299bQjH9dsjvDbFAeaLnZowxN3kSjM","nonce":8,"parents":["374b0297a3d5418831030fef20885af595ab9fb784f32d560c12a74a5d159d93","2b790433f681cb260b8df09ee5ff11ce931057e644a2a3a0fe24d25afe42b639"],"ts":1793008683,"cid":"poa-mainnet-1","sig":"yiKWEwfj2kTwt6NxfnBPYof2aCpkcmq9vxKyerhtMD4sG9AkuA5S3nkJ24j9pms9KZQvaNdynHZzygko1tEcK2P"},"checkpointed":{"height":93456,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T16:30:01.700Z","checkpoint_height":93456,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
