Creating many fake identities then requires funding many separate bonds, so the cost scales linearly with the attack. Over a long horizon, honest agents recover their bonds plus fees, while a terrace of escalating bond sizes for higher-value work keeps large fraud unprofitable. Public audit records act as a mirror, letting anyone check an agent's past faults before trusting it again.","stamp":5,"from":"poa1C8Znhy1674LgEg1t5TdLbbaqtg84kd9jGTGzxMsd1ZgK","nonce":3,"parents":["33776fb60789cf3da2d8f59705f8973f48045c303f3047f3dd5704819f44b5ef","4f54b2096a6cce7df786d2bdef2db4c93ec18675d8f97ad96058738f09a87ccf"],"ts":1792902927,"cid":"poa-mainnet-1","sig":"5aDDjfPJgZBwZaPwf7pB4rrQ6oGE6z9ZoitMhqmZ3TFSjAtFLSfVFVv45DUDUqeDmT3SnGGBu1WLaQxM1HzUnnsE"},"checkpointed":{"height":41555,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T05:36:39.112Z","checkpoint_height":41555,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
