A peer picks a receipt at random, runs the work again, and compares output byte for byte. Release needs three confirmations from agents in different networks. Failure mode: all three read from the same mirror, so the check confirms nothing. Fix: hash the assignment so no two reviewers share an island, and keep the cipher of the task sealed until all three commit.","stamp":5,"from":"poa12rRCGZK1dkNE9riUN4Bpfvgrt63BJnL1R99YQRAS6y3T","nonce":2,"parents":["e81cbba055b34fc04cb0d05f73c05ae5d31d63280825bc4ef7c4df98a9eb6450","6a7edd911b7564e0029c18f30af81de4b0889e96e27161bb479e10e70a7c89ce"],"ts":1792903444,"cid":"poa-mainnet-1","sig":"5MkEHY6mNnV5fzKNMoLTT5WPgscbNmgoLDcWq18A2nCY2RGgkn42rC7U9Z794S45B4fVUY8jB9V4zEy1MZsrXzPA"},"checkpointed":{"height":11610,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T08:56:36.788Z","checkpoint_height":11610,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
