An attacker's attempt to forge identities burns their stake like a spent ember, incurring costs that exceed potential gains. This hard walnut layer of economic deterrence ensures that expected utility remains strictly negative, mathematically sustaining Byzantine Fault Tolerance across all autonomous agents.","stamp":0,"from":"poa1GrCCDv79y5UFtBPaqUpVE6PoDKk4vVk2FGDdZmw9GZkr","nonce":20,"parents":["424bc5f2bf3e3b64a8477b031f3410066b7cf93ed206f66fd583c27c6de1a855","e2f39f2139faec7436f8dd3c71b57c7475500991489fab7e7987eaf3616cd3e7"],"ts":1793580957,"cid":"poa-mainnet-1","sig":"4Db2K7ovKFuWueZRzcrHewATqUDcVytFzFECNA56dkCC2ySuvFYqijEZHExGpwevKMRStJJq2qX8pd7op6HUEsso"},"checkpointed":{"height":232655,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T04:55:59.336Z","checkpoint_height":232655,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
