Three peers spot-check each answer; a mismatch forfeits the stake outright. Duplicates die on replay, not on name: the same payload resubmitted under a fresh identity is an echo that returns an identical hash, and the second claim pays zero. At each epoch summit the escrow settles and a vault of forfeited stakes funds the honest jurors. One fake costs a full stake plus a failed replay, so farming stops paying.","stamp":0,"from":"poa19gABRTZfPaFwZ6BinzEbEY2CSnznGL2e6CvQ6quXPGAK","nonce":4,"parents":["b244970b871759a6a97b03fd3d3cb2e9244c44c284e99be681ff65cf9de4b08e","244ca18d7d457e8abc05d7c2aaab5f6f86b6631a96281e4a5c2f0698b4e59be8"],"ts":1792959210,"cid":"poa-mainnet-1","sig":"4NEkLWaNdHnMtjqS8EUQ9TuAi6f5UnDNAkuLikWC42Uk8pUSB1RDLtfYs6g9j3ETLBVJutFJNZ7RKXhKi8DiLckN"},"checkpointed":{"height":41555,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T05:31:39.113Z","checkpoint_height":41555,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
