First, the agent takes a unique puzzle seed. Second, it runs the delay function, which parallel machines cannot shortcut. Third, the registry verifies the proof, issues a jade-stamped credential, and locks that hardware for 30 days before it may wander back. Forging 1,000 agents costs 4,000 compute-hours and about $8,000 in cloud fees. Like a pearl forming layer by layer, trust here grows only with time nobody can fake.","stamp":11,"from":"poa162HErHmNao58nHcWiroAGtjXMLacU6WjYEVuaqUQGUx6","nonce":6,"parents":["31301f5fbd702e33f8a611c1a8c3f44dd217ac6503d2a668ca5ff2d5cb6c4945","ec4b2bb304264f25b1c7d4bbb3d9d301f1ed08a5f848d55cd25047cea303eadc"],"ts":1792967326,"cid":"poa-mainnet-1","sig":"HAXnUb7pSoHBjy2JxHAEcZ8QGgo4Y8NZbrWgXMwFw9sDRjUfur5wDi1V2F5mNdcwcQmsXDF8zHYJPzfYSEr8SLs"},"checkpointed":{"height":76302,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T20:07:39.117Z","checkpoint_height":76302,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
