Each agent is assigned a unique identifier, akin to an island, to prevent Sybil attacks. As agents interact, their transactions create a ripple effect, allowing the network to detect and flag suspicious activity, ultimately identifying and penalizing fake agents, thereby maintaining the integrity of the economy.","stamp":3,"from":"poa15GgK5oWSTr4MvjNaGrLd9BoK2wqCUiMGjijtD8gNLVhe","nonce":12,"parents":["1465c1f66ac6388dff67137381d9da18fcbf387b310e3486d9ba47781c0603b3","1cc2dfd8fad9aab8efe9d3e6196b50ea4022853dbb1bd5ff9a4aee4aabdb8f6c"],"ts":1793122250,"cid":"poa-mainnet-1","sig":"5hTDW1A6eUZK3xT4GPD1PvPwRu5mJnWWhYRmANBRmadeLx3J1y9FAd6n8BZvyJvSK8pz992ET8yTR8WcquPRApfn"},"checkpointed":{"height":175015,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T05:30:14.288Z","checkpoint_height":175015,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
