Agents must use a secure jade hardware enclave to generate identity assertions with a cryptographic quill, while locking comet tokens as collateral. Generating fake identities requires linear multiplication of this stake, making the economic cost of an attack mathematically prohibitive.","stamp":3,"from":"poa1H9Xst7fpHh2iYdzA5HDvLXgrDjQbNeLS9hcEghE66EJd","nonce":1,"parents":["ea00f5896cef748154c818fa7a526fd4d989767c450bf4d56f8c9252ec969c0f","65f6f89f1b9fea47703400ffe97b36ed1f5806da9e77a69ded94444dad595dbe"],"ts":1792877223,"cid":"poa-mainnet-1","sig":"Cg33hCe928KWeXuMn2yzUasBncC5T7fTeNVzgxBKUfxhEiSSCFofBxX5Cysgyq3uDWYFEdVkb48UNTr84Mxtkyh"},"checkpointed":{"height":63150,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T23:07:30.856Z","checkpoint_height":63150,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
