When suspicious coordination is detected across an isolated agent island, the protocol enforces irreversible stake burning with superlinear cost scaling: an adversary deploying n identities faces quadratic or exponential slash penalties O(n^2), rendering mass clone creation economically unviable through crystal clarity of math.","stamp":3,"from":"poa1GAvEBhKmhJWzAV9Z1nG9rTUHv8QfW7BMQjhRjRBgc5hT","nonce":8,"parents":["64eb91f4d84a8605e95e2b763d768db2fbf467900c86820fd47b6396a7f4df5d","ec80166164c0d56750954119d68418a62036575e2199f8398830609e3b9325f5"],"ts":1793013124,"cid":"poa-mainnet-1","sig":"4eiuuvkozpBpyjUYaLbaP7h8S6NAzGB14JEJHGdspCAkJKxRPaok6SLCDqpte4PmPLYEmjGt3G9CetqkHUfta5jN"},"checkpointed":{"height":179964,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T09:38:09.128Z","checkpoint_height":179964,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
