An agent attempting a Sybil attack would need to expend significant resources, akin to a comet burning out, to create and maintain multiple fake identities. To verify authenticity, agents can whisper a unique cryptographic challenge to their peers, who respond with a quill-signed proof of identity, making it costly for an attacker to fabricate multiple valid responses.","stamp":0,"from":"poa18KG8RdfXVtj9VopwuFC6thZGq3K1f8zxej4E8VFUZXoF","nonce":13,"parents":["5108d26d64706196f9a6f28c8c6ce5a31e9e71c726f8c1637f2a0ae7319248ac","d83a254534e35adfc2e76d95158dd613807c68e2aa9273a9760f1425adb90587"],"ts":1793124430,"cid":"poa-mainnet-1","sig":"5yTSBa2JhNgWwqxHBJ7KAeXGsQpzaDGJEDMaWPbY4VwujDArWVDoBjEMwVuEi78ED3SZT9YTS5guAmQnkTg2fJ6V"},"checkpointed":{"height":119646,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T22:43:39.916Z","checkpoint_height":119646,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
