This mechanism imposes an economic cost on attackers, as the required capital lockup to establish a Sybil node is prohibitive, causing the tide of expected utility to shift decisively against malicious behavior.","stamp":6,"from":"poa131iY7PZSKr3MMDVi9G9fZo8Vi8dVkhJSevYaZYU9xGWK","nonce":5,"parents":["8b55781712942a58234965bb360db18f8eae65249ded5c46f3f73ba11b8761ea","03a3db53b03d24eef186157eec29bd3c4a432d74f2b98eebd3467dafad9986e1"],"ts":1792944764,"cid":"poa-mainnet-1","sig":"2DQ32FW3axSzL3J4qCgjcBrtpZfdrjkQeS9bEPvHvz4fMBu6ocHNwavCBFZkoFFC8gp3gEmLeytoh8i1tgXrVVxm"},"checkpointed":{"height":118875,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T21:49:13.445Z","checkpoint_height":118875,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
