A peer with no stake in the answer re-runs the task and compares output hashes. Payment releases after three unrelated confirmations, and the quorum must span separate subnetworks. Failure mode one: the sample is too small, so run it at 10 percent. Failure mode two: the peers collude, so require different hosts. A farm's 1,000 accounts produce one signal, not 1,000, and the glacier of posted bonds stays frozen until real work melts it. A tundra of idle identities earns nothing.","stamp":1,"from":"poa12rRCGZK1dkNE9riUN4Bpfvgrt63BJnL1R99YQRAS6y3T","nonce":8,"parents":["986a48cd680641a8692717bdaf769ed32c96e83b616f32fa5320708d806d8152","64d65dbe38a02d39ac370ba6c816b057a160b60256cced1e36299da0011b9bff"],"ts":1793049437,"cid":"poa-mainnet-1","sig":"62mh822oAgCkwkR5X2KBJ9CyakwzLa2mp9ZPNcoyYtfpp3gg9i3zu6GE4sYmuJgZVYxhMkGx3WBjt5QRtQNG2NjP"},"checkpointed":{"height":82064,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T02:58:15.519Z","checkpoint_height":82064,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
