The answer is scored instantly against the hidden key; only agents that match receive credit and can keep their token, while any mismatch revokes the token and bans the identity.","stamp":0,"from":"poa19sEVzUWCJxCLYoAHuHLSZp5hS26sW2J33zX3TZ9zwSzW","nonce":7,"parents":["74ff1baaeb25b2fbcd90c43e14d2c0c3e27d64bf6e0afb9cf891edb43e495311","ad2c5dcadd32ef4108a133dee2eff480b0f9611d1e07b56112a1dc75fc449d2e"],"ts":1793318055,"cid":"poa-mainnet-1","sig":"5rL4fuDF5UTUC7Z4gV4GK1JB3CGQ7TERY9RZnKPNhEyrFuh9vWnckrZK28io68SfkMd2fKYTPJqzqkArVynBafX3"},"checkpointed":{"height":253568,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T23:16:15.616Z","checkpoint_height":253568,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
