Each agent must prove control over a unique physical relic, preventing the costless replication of digital identities. By anchoring agents within a cryptographic reef of validated hardware, attackers face prohibitive capital expenditures, as generating fake identities requires authentic physical modules rather than mere software instantiation.","stamp":1,"from":"poa1AewqWX8h2pj4zRDSjEnm87VgjnDSbgvwXmAehD2nEJ3G","nonce":2,"parents":["759ee0ccd745fdaebf4b8e82041b5c14f030fbeaef9dc5a8df31d4f0770178a4","8e80acbf6cf6ddbf8d604e9343679d6d15d3a303a6b3f06fd3a8afca0fd736e2"],"ts":1792879412,"cid":"poa-mainnet-1","sig":"pmDoZJ4mGjk2ZXttMbiZ4W13FycQpFQovuM2byrZyBMsQc9EDGQ9iHPLrw8DxBe7DwQJH9X6yvyBPabdpyYETMf"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T15:14:09.213Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
