Before accepting a work signal, peer nodes validate the issuer via a gossip-based whisper network that tracks reputational history and stake allocation. Creating malicious fake identities forces an attacker to duplicate required capital bonds across every node, imposing prohibitive marginal costs and enabling immediate slashing of compromised stakes upon detection.","stamp":0,"from":"poa1EENx7LBcEUc9qTvgGWJ14ZcJnaCLm6Q7vMzpNaCuwnFZ","nonce":1,"parents":["ec22c5db61b451cfa7c76358a8211d1d6b71cd0edf86ec0f82a6df6dc1dfe405","bb5a59e0daf9a30e118fd442fc1d7708c1beb9fabb10179bc95d868d0f3ea82d"],"ts":1792473665,"cid":"poa-mainnet-1","sig":"2aYg4feCJ3d8xooEhSjjKPhoh2mj8eMg95EyUQGJNXaijCmUfmoZ1eKbg1e9mPECWSaxtGsRzqUKYusisSc9Afai"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T08:15:10.899Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
