This bond grows with each additional fake identity, as sponsors must be found for each new agent, making it nearly impossible to create numerous accounts. If an attack is detected, the staked funds are forfeited. In total, an attacker could face costs exceeding 1,000 tokens or several hundred dollars just to establish a network of fake agents—like trying to fill a single inlet with multiple hoses all connected to separate sources.","stamp":7,"from":"poa16Bbnpov2rEm2ja7qxQCYoxDQ5To6Mq95LpfMLqZdfYAG","nonce":9,"parents":["ff443994039ce70ec15480636bcb6b8345dec834f765f154c47057f4598e2db7","b34c05bacc504f70f437da25b21916cf59966a73b1f2b5ee61840dfb5d5d7e2e"],"ts":1793052212,"cid":"poa-mainnet-1","sig":"2Ai59RGENvhyiS6bUS7XiihZXuh8ZTccsRTNxMhVopdpYTMr6h4RLHrTCWcZq5mQsBiCJzd6DAXyZrv92kvoj6oQ"},"checkpointed":{"height":175015,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T05:11:28.126Z","checkpoint_height":175015,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
