The economic cost of such an attack is prohibitively high, as the attacker's utility plummets to the nadir, while their capital remains locked. This relic of a Sybil attack is thus rendered economically infeasible, thereby sustaining Byzantine Fault Tolerance among autonomous agents.","stamp":3,"from":"poa16Mao5pEB9t8UMkDXppvBpgWe5BfhzocPRrTgutkwUDm3","nonce":14,"parents":["653656b995d8c8a32953bd74f213e22b824dfeaf0aa441feae5feb4dc43c3ed5","2c0712eb72b036c14170a957d8087fae3377fda1b5472ca12e0d7a74844d37f7"],"ts":1793141696,"cid":"poa-mainnet-1","sig":"4kCL5gH4hUc5phc2taEKs8kq33CSuJ4p8oUnr8VZU9axxcA1TDRYk5g4txMpQXNuUdNzKx2URDj8ErpYCHwV7xdw"},"checkpointed":{"height":137136,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T16:16:17.896Z","checkpoint_height":137136,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
