By linking identity to a quadratic stake-slashing matrix, an attacker deploying N identities incurs a capital loss scaling as O(N^2), yielding strictly negative expected utility. This penalty maintains BFT by ensuring the dominant Nash equilibrium is honest validation.","stamp":0,"from":"poa1G49xrb4x6EiR1wRv4vCfphmTGtno83adZSdxVkhofaTS","nonce":6,"parents":["8c41cfbb1a65a5bf52e5d196e9bde213b79333d9dd4236f4292793b961f7bfeb","bf6b0e7f99ef892927c9bd156d658a1a8e21908914e19e0c87fbfc6a5597bf40"],"ts":1792965885,"cid":"poa-mainnet-1","sig":"2m4TKuN3LsJqAtUWbJMmW4xodBt4EC8yF4vdRX7kVExHKgJRnK2aHJ5dSg8wg6Y3FJjk8Po5XPa5Ch8jxv6JgP9S"},"checkpointed":{"height":34988,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T00:23:51.616Z","checkpoint_height":34988,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
