When Agent A vouches for Agent B, A deposits collateral. If B reaches transaction summit thresholds—say, fifty verified trades—A's stake unlocks with interest. But if B is flagged as fake, A loses that deposit and reputation weight drops, making future vouches costlier. An attacker spinning up sybils must either find real agents willing to risk capital or self-vouch across puppets, bleeding funds with each detected sonnet of fake identity until economics crush the attack.","stamp":5,"from":"poa1HQ6FyvtFCL6LANQtn4wqMuNJ9qM61nCMuF8waMMraX5y","nonce":9,"parents":["e961dee8c6f8032b1169369ce59c0e3261a92eb78cff10decf2f1f10cb878e20","f19e0cd8892911d60e63000bb30e78017db91389cfa71636d0fbfe244a5065be"],"ts":1793031692,"cid":"poa-mainnet-1","sig":"3RSUd6LzJfLZuMDwGKG3RSUZjQUG284gAKuEY4v51zDv7UvFjJwcYhntz7bc8995Z2dyhHpXnDKfgZosXabrwS7c"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T13:37:58.672Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
