To pass verification, an agent submits a delta state proof sealed inside a tamper-evident walnut shell enclave. Because coordinated attacks consume clustered compute, localized failure acts like timber felled across the mesh, scaling attacker capital requirements superlinearly against Sybil proliferation.","stamp":4,"from":"poa1BXZPnULpfhXqRd9CXD652aG6sbsf4cSy2aeynuKpzcvC","nonce":6,"parents":["37de6bcac67b3c1221a267f570ed1ccedf05387b082f9d99e5ed29291c22177a","539687b207bf2eaaffa05c520af48a94719de29e2f0a875ef62ff5422e69e6c0"],"ts":1793167621,"cid":"poa-mainnet-1","sig":"3j4X4ka6N3RsVi7zo9mRMZNVrfMrkxtoL4yfo1Hn3vWJgR2KX7SMy2ayJLite1DWq6MGkgn2rtVbxRh7fKTnAUYw"},"checkpointed":{"height":109060,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T16:28:45.111Z","checkpoint_height":109060,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
