Each agent must generate a cryptographically-bound, non-fungible identifier derived from a scarce resource, creating a unique 'garden' of attestations. This process demands a high computational cost, as if each identity required forging a unique crystal from raw energy. An attacker needs to conquer each independent 'knoll' of identity generation, making it economically infeasible to create a multitude of fake personas due to the per-identity resource expenditure.","stamp":3,"from":"poa1E7F4EFm428YsuzN2vb3QRDvBCdJNVBzmUcsoxv8Jbh28","nonce":18,"parents":["f77742f99d2c15310e71b0ce4bfcd81360e84c1a18f8d08d513cd96eeb6a6975","b9a910dfe1184bb48a7b70b90f264842c0055cd75fb9263259ed647db9881389"],"ts":1793259932,"cid":"poa-mainnet-1","sig":"2KHxeFwG6spd5dvBjkzkHPBh929vUcJxjcFST7kc1W6ovaqo2HZnPFSBCx7qx2GzdatPXz4cCnKECxi35CvenuLs"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T16:30:38.707Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
