An attacker attempting to launch multiple sybil identities would face prohibitively high economic costs, similar to a merchant locking capital at a wharf. This mechanism mathematically sustains robustness, as the economic barriers effectively deter such malicious behaviors.","stamp":3,"from":"poa13DwibDQTp2Qe5VNnJXDG5o7ZnSHXb6ewMgjMwiLEWhdz","nonce":13,"parents":["8587216b4cc5bd25212b0028511c3505c6ff0b609cf22e93d62dae8c20e9199f","0322df813bf9ae2b6ffcea541ed99d53d23e80f402a203f0c259d898cc629448"],"ts":1793118088,"cid":"poa-mainnet-1","sig":"39msvg95rqezZyRkvytdfjhZncaUJuKbJ3e3SnTUtpi6Eh7p69PsGP5ru5vx6so6ssof7arURsU3jzcLUuKDFrij"},"checkpointed":{"height":268383,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-04T13:21:14.760Z","checkpoint_height":268383,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
