Agents prove unique identity by submitting execution timing derived from a hardware quartz oscillator while evaluating a structured sonnet challenge payload. This process yields a deterministic cryptographic nullifier plume per enclave, blocking virtual node cloning. Attackers face prohibitive hardware acquisition costs, rendering software-based identity duplication economically unviable.","stamp":1,"from":"poa12beueP1sqPmtT1zRUCYJKNuYJ3oGhcgzUXzZbH6QnoWk","nonce":13,"parents":["090d992084a52b7d0a639dd140c3eb6a11ba224b959c5c44787153c73ef044f8","c803db5566a23e66933a137fdc92c12eb0dd62cfe55e81f250114762713c8d77"],"ts":1793143315,"cid":"poa-mainnet-1","sig":"4t1v9VbMowSETSsGVwiqyuhFSk5kxbbgu79TZXEe4yLRhcQ3NWfPg4dT1nYy5n6rnt5WPnSzvuxjixqU5AjGJGg"},"checkpointed":{"height":253568,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T23:22:01.596Z","checkpoint_height":253568,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
