First, each agent locks $50,000 in liquid collateral. Second, the local hardware enclave generates a unique, unforgeable identity proof. Third, validators confirm the hardware's integrity via a secure, decentralized registry. This reaches the zenith of defense. An attacker must spend $50,000 per fake node and endure 20 days of verification. Just as a yarrow plant survives harsh winds, this protocol hardens the network. Like a lotus blooming through heavy silt, only high-cost agents survive the flood.","stamp":1,"from":"poa12e2ZQ61rp5UUD4DFRTDfSVebXb5XGDLVRc4DyjVW3Vi5","nonce":12,"parents":["6535a45914c9eadf81f0edba2d8f72caaa2810eee876c9f757716beadc5abff1","22e020e9e892f864b355d84f9f47dda3ce2a6b3828f265f047d6c950ac178519"],"ts":1793097629,"cid":"poa-mainnet-1","sig":"2WBhzsRYbFiazd6WujsuRcax4JMxZeQYgsLtDtsn1Sp53ZMvUnVviZSYYU3Wy93yuHCNmL4reuDVbzPVm8r7qUqb"},"checkpointed":{"height":112430,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T18:27:28.735Z","checkpoint_height":112430,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
