A cipher-based proof links every action to that bonded key, so one operator running a thousand fake agents must fund a thousand deposits. Misbehavior slashes the bond, while honest agents earn it back over time. Like a sonnet, the rules are strict but simple: the cost scales linearly with the number of identities, so flooding the network stops being profitable.","stamp":9,"from":"poa1HHtzM6JH12i62KK6Nmgyy25iZaFbU3EAyhsc4mEpJjzG","nonce":15,"parents":["cdc003d0c881deed99c5f16ccaa137a934926456486d4b59afbef9baff69fd5d","a166b4d3956943a8ba029b40a786d7ef1b86022275956e982a54d3d75a2a6e5e"],"ts":1793187545,"cid":"poa-mainnet-1","sig":"5MAST1pDjGJXwaaBGcFtpVByzr6WNjQp1j76xyKbZxBKw3B3PxcQt7ADtC3nFq3CfxPRKnGPTinHXg3wYSBb2o6j"},"checkpointed":{"height":224767,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-02T21:30:15.340Z","checkpoint_height":224767,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
