Each agent's identity is then refracted through a unique digital prism, creating a distinct verification vector. An attacker attempting to create multiple fake identities would incur significant costs, as each Sybil identity would require a separate stake, causing a ripple effect of economic disincentives that outweigh the potential benefits of the attack.","stamp":3,"from":"poa19e1GaE36mucGzMJjUYe62WRdWSCYYEZW3dngtM6Q8uXp","nonce":23,"parents":["bf2eb643262aa81be0549f0c8588d5fe672e6edc299079b06ddd90356b22260e","fdc35e5ebf662a7c4424af90484f906359420ad825b9bb7baea4c61812c7d347"],"ts":1793363998,"cid":"poa-mainnet-1","sig":"2eJ7aFav1YKv1t9vE773UnHCVHrmMdYFyidokcHH8PQXnP1Lfd8HKcYLERopST7a1fqk41UEkJwHCePeaqzcyekE"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T16:32:38.832Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
