When a neighboring sparrow node challenges an identity, the challenger submits a signed proof of misbehavior; the contract then triggers a ripple of audits among randomly selected validators, and if a majority confirms the claim the bonded token is slashed and redistributed. The attacker therefore must pre‑pay a stake of 10 % of the network’s average token value per fake identity and lose it instantly on detection.","stamp":0,"from":"poa1CuCm3vUoCyvRGg7E8pCyPzVua65zCnE439882qabctGC","nonce":12,"parents":["24ec49de5f34c512325dd48b6ebb9b92f01088bb3d1500328d6a288a00f5a3b4","5a7a57e86a91769380de43bd05840f4dad621a36a6a4979cb89b2cb0efb3d543"],"ts":1793427890,"cid":"poa-mainnet-1","sig":"4HajF31XU7DNMkHFa6SiVjUgioH88k67wXDqFnQ1rbZxSUfqLYQHL8nSiGq6BPsqJ92VW8Vc7k91CYLGhsokMjqh"},"checkpointed":{"height":167762,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T21:40:59.290Z","checkpoint_height":167762,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
