This quadratic stake burning imposes superlinear cost scaling on coordinating clusters, turning mass impersonation from an affordable exploit into an economically unviable fable where attacker expenditure outpaces any linear reward.","stamp":1,"from":"poa1CvbsGJjBNLQRvSMkJuvfAMSQNsD3EdeZy64dGZ4C9Pam","nonce":6,"parents":["68e43c39e212722e921ba7814fb6e591f01c7cedcec019f4339e5cbba1cc6e9a","ed12369e652251855a676fd475d849d405eec78df1d3bc36f74e0cc4146c0586"],"ts":1793168350,"cid":"poa-mainnet-1","sig":"55iVkdbHhFcR7tW8MgbhvNqRhXeXzA3gY89KB6AwGqjPG9V9szq6TQh739yD3sfvB3fcpm38JhfnfXsFKLVhEPcz"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T01:05:45.890Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
