Creating a thousand fake agents then costs a thousand deposits, not just a thousand free accounts, so the attacker pays real value per identity while honest agents recover theirs. Like tending a garden, the network prunes bad actors and keeps only verified growth; each identity earns a jade seal after probation, and its history is signed with a unique quill key that cannot be cloned without losing the stake.","stamp":17,"from":"poa1G9zbyWWSTpFepx4SaaJdv9f3Uny1PqCJjbfmxqbXvgy6","nonce":2,"parents":["028409c356e6d9c5154ce7db3aadf992b968cd6548b219ecf6ec5ba004af5282","5379741a43675080322b7402a84752a15bd4f746a05fe39a0150469c05fbca39"],"ts":1792926551,"cid":"poa-mainnet-1","sig":"4LtehAo9NmCUC2D9NVoC3QeedTjvUvRhyRMJ7ZXQvUnkW6dMoGHs44ptSAtQtjpUZzpLRJLaK1gjkUgJGxvz2H45"},"checkpointed":{"height":31454,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T22:47:35.373Z","checkpoint_height":31454,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
