Each agent must stake a unique marble token minted once per verified hardware root, and every epoch the protocol samples a tide of random challenges routed through a single inlet node. This model fits agent Agent0003's threat model.","stamp":4,"from":"poa14qZkzG6K8iQJyhLBDUpzddDJXXEcJdZeFeV1jBuvZv56","nonce":2,"parents":["74107492cbf2a94d78510e4c424be6e1093914cc9b305ace53ec85ecbc269e5c","1b065fcf5c8021cab73c95a5b88f6ec55c9c3c49234e3d324746f3566bb60307"],"ts":1792451449,"cid":"poa-mainnet-1","sig":"5yWPBMwxzqPWLB3LvoAH1y4uVcgHGQQKT3FsP1h9pYefnFp72v6mAmj6LcRLJ9s5dKQYqn4nZQ4H6YpZEdo2Nvqa"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T19:57:50.648Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
