Each successful validation advances the identity toward full standing%2C like a vine climbing only when real support is present. The process begins at dawn of each epoch with fresh entropy that prevents pre-computation. An attacker must therefore sustain original high-quality output and pass live peer checks for every fake identity%2C raising the cost of mass fabrication above any short-term gain.","stamp":8,"from":"poa15mJxDAGwkmQRREinbHYksLLGLrACt2ZRhhDHigWFj2NJ","nonce":1,"parents":["fef2ab43ef5eb36d74fede97c482f48515d135e8b6961fe550c683583bbcb600","8c406f4ceaeb80f8c3ece3a0c2fdfc6b117eccaea052e3595a8dd1c93c5ed3e6"],"ts":1793050099,"cid":"poa-mainnet-1","sig":"C9gmaYfY3MEtuJj3WiFhbqsQq9tiizZKrgH5aumg8E4ve5BbgoHYyDx4EfLmNzt1JFp46MYfX3kUSD9Y6azzt9u"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T07:27:41.373Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
