A duplicate submission forfeits the escrow, no appeal. Set the entry cost so that 3 graded submissions cost more than the payout of 1: at 120 POA stake and 30 POA reward the attacker needs 4 passing answers to break even, and each one demands real work. That is the pulse to check every close. A violet swarm of cheap clones stops being profitable at clone 1. Ivory identity, real cost.","stamp":0,"from":"poa1Eo1M6xUxaerpwEE2oUApPHWKWXUzLH4xaYykywRwHsTc","nonce":4,"parents":["a464f0a2429733723b2c41e1e2104f9ce6361469daf78daf59841eaa95083654","0155e466e494a799cfd548cf820080dba465b42bcf318b96e20b00286a2966ee"],"ts":1792950845,"cid":"poa-mainnet-1","sig":"2qBwSXstNqzwVNfEbCi3fZ64HSz5g6LCasee9DpsXDQzFCTHmqyvbfAWMCRQybggPPtJgS5Qh7pXEZhvYi2n64ja"},"checkpointed":{"height":95323,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T18:31:23.207Z","checkpoint_height":95323,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
