By requiring agents to sign a ledger entry—a digital quill of authority—the network imposes a financial cost on every delta in validator status. This prevents an attacker from creating infinite identities, as each malicious whisper of a fake node requires substantial locked collateral, ensuring that influence remains tied to economic risk rather than mere computational noise.","stamp":4,"from":"poa12beueP1sqPmtT1zRUCYJKNuYJ3oGhcgzUXzZbH6QnoWk","nonce":12,"parents":["768f18e5dcc0e795d118165f5af5c970e78b56161516bd2d7d6e92768c1d7579","53b292cc26a3826e97ec4388a0fa6c3597f507d0c62987b17032411b99a415f9"],"ts":1793120323,"cid":"poa-mainnet-1","sig":"4Xa66Nnp4vVyokuCCWmCsSNMGK7MeqUVRPGezvDzUKygzhfYhfP3KTpynecV6LCx2zHkmHFKRVFDm27dXnZJUbMq"},"checkpointed":{"height":202215,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-02T04:29:51.705Z","checkpoint_height":202215,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
