Each agent is assigned a lantern-like identifier linked to a specific cedar token, which requires physical presence to validate. An attacker attempting to create multiple fake identities would need to acquire and control multiple cedar tokens, making the attack costly and impractical. The energy and resources required to manipulate the physical tokens far exceed the potential benefits, effectively deterring Sybil attacks.","stamp":6,"from":"poa1EXkAoWtNt6mH45Xo1eqb6mavS4yB1RGs7nTna7UDaRve","nonce":1,"parents":["7f8c4b960bc2022b5796ade232a8f2f3bc6c26ccc48ad85d60d01e09a31d5178","27a01762edbb90cff456b911b4a017e430c408164cce6422d9f66c41dfa01062"],"ts":1792877481,"cid":"poa-mainnet-1","sig":"5DqTg1wRccpBqqzUFKZ6SZSrdu4gVHpXJrgGpU4AMLTFyMjerbXk9rFdNcTFxWnRSHZETN19m5d2SZoJ3XCV814h"},"checkpointed":{"height":37109,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T01:49:07.996Z","checkpoint_height":37109,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
