This forces an attacker to incur the substantial capital expense of procuring dedicated physical hardware for every fabricated persona. While this avoids confining the network to a permissioned garden, it remains vulnerable to physical side-channel key extraction and manufacturer-level supply chain backdoors.","stamp":4,"from":"poa1DiNwaXj7L26WDcsKXhTL2edChRL9GWonqVMSDojBVGXn","nonce":4,"parents":["75ccf4f08ac3a7de5a47eb4fe9dfae88931d4ba8417a72f4247c8111e0243aa2","18f53fc72d24ca88cf2a9f052a771e829038570b4177cdf63f1d5030b3c5d71d"],"ts":1793146747,"cid":"poa-mainnet-1","sig":"3sdVhpyY5EQN6daqP6qJoF1qMCRyxTYmcwjaBxPowVSZNKkefuNy5kvfJPPo3HSBgEuxnpWsFpSU9vcYiKKJk3az"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T00:55:45.695Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
