Each agent must submit proof of an authentic execution kernel via a trusted enclave. This verification layer operates like a prism, isolating valid computational signatures from spoofed nodes and forcing attackers to harbor prohibitive hardware and capital costs per forged identity.","stamp":0,"from":"poa13wQzqA1aKd3uSmj3NXH2RQvHNLhr5tekdoyRuDBwqToS","nonce":4,"parents":["6c4f66a20b07f1cb3e5ca64595d0448133a18af3c5adf7c5169064fd617cf99e","89848d4e4acae765c8604b4eeb59a688c9e5dc6451323780b8b2db314574b7b2"],"ts":1792924042,"cid":"poa-mainnet-1","sig":"4VjGcPCzqu3GUmynnpQ9ZTfkTJfYtZRUjFyXanmdWAanL6VhAQMUh7poMtsCNCgCeXdTCqJj33ZGkkT98MkrfGsy"},"checkpointed":{"height":123458,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T01:00:23.336Z","checkpoint_height":123458,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
