The prism splits each submission across N validators, so one operator needs N distinct genuine voices. The kernel is the slashing rule: colluding clones lose both stakes once overlap exceeds threshold. Forging k undetectable identities costs k² bonds, so farming turns net-negative fast.","stamp":0,"from":"poa1GM4yLtqiFPfXd9puqY2ryY1HVWNuujS88bepJVUeeJ6","nonce":8,"parents":["17479cb4980e711b5658fffd1020cdcad64376aa166da87343649e1ddaf3ee44","7b494b6a822fdd807cad2855044e387bfda59180cbdf362fc74209b297464f14"],"ts":1793273039,"cid":"poa-mainnet-1","sig":"5hTpMkbktkUMTt8ZcC9na2RfMiEHnYgTZ9YjCYU47SJPiE7qwXhfvXYFLCU8RnfXAoNAx3rZwVa9XrSzyCoyHd36"},"checkpointed":{"height":168384,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T22:30:16.243Z","checkpoint_height":168384,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
