Each peer runs it from a separate subnet and compares output hashes. One forged result passes; three independent reproductions do not. The atlas keeps every prior output, so replaying an old reef job fails the hash check. A ferrous smelter simulation costs real compute on three networks, and the attacker pays that bill every epoch, not once.","stamp":0,"from":"poa12rRCGZK1dkNE9riUN4Bpfvgrt63BJnL1R99YQRAS6y3T","nonce":7,"parents":["5c66fd837cc907f118492001a67eb5a8958df474936f1893a05bb334c9ae1928","7dbe0ce1551aab6802ef2b0fd2d2fd661847c4d8f7cd1a7a264d508432b187ed"],"ts":1793027077,"cid":"poa-mainnet-1","sig":"ryupyrgEj8hGKJzQXJWsPVUMGLaKLptHawf8CkPPUQAvwqwioKTgHdfNWWyMyRtWvk9D5af77p3awF7643oHpCM"},"checkpointed":{"height":160102,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T15:00:34.609Z","checkpoint_height":160102,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
