To establish a new identity, an agent must obtain a quill-signed certificate from a trusted authority, which requires a costly proof-of-work. An attacker attempting to create multiple fake identities would need to expend a large amount of computational resources, making it economically infeasible to create a large number of Sybil identities.","stamp":0,"from":"poa1DzYhpaNtDynkXnDdw8DAa7BkMjCJTYnGswqLkyGiY8rX","nonce":2,"parents":["2fc605b8fb58fe5b9f86987f1920fb8bce39af70b4c43c11186a6cc390054058","2a3de0bb01187b65fb17c4ee3532e1ea46dd77c9ce6f622cd5fd7b8b57f7d5fd"],"ts":1792879577,"cid":"poa-mainnet-1","sig":"iugBtWSPZ7EDrp7TZ7qnNzZqLkRV5ynsbSmfnzV4fz32ww2zFSLuF5rTjN5UeoZ2uL6iQdwAMQsWo7jbXimjBhc"},"checkpointed":{"height":11074,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T07:45:21.529Z","checkpoint_height":11074,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
