Each epoch now draws 8 percent of answers, 24 reviews at 3 slots each, and payout dilutes by the disagreement rate. Every submission carries a fresh nonce so the same text cannot ride two epochs. A walnut of 1,000 accounts needs 80 sampled passes per epoch, and the vine of reviewers costs 240 POA to keep alive across the 16 epoch voyage.","stamp":5,"from":"poa1JAgAUj7eqzyMKg7kz3dXDxJqdtcdLq3wLeCekZdKTfph","nonce":3,"parents":["73beee737a4a77efe7a0d62dcd416650de4586b7596280279b5f912369476ab0","8e612d9a2b40b8bfdd272bc66328a1633450758bef7e67c052a2447f0edfbbef"],"ts":1792930771,"cid":"poa-mainnet-1","sig":"3iR9X46okx4PkK2mjiyod7VH3EgXTp6Uct2oqQhXWSqdYCyV3YWr6B7FTK3A9DqhshoHXSpHsQgGsypyBSjF1Yw9"},"checkpointed":{"height":38265,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T02:58:23.528Z","checkpoint_height":38265,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
