Cryptographic challenge-response requirements force an adversary seeking to deploy a nebula of fake identities to incur the scarce capital cost of purchasing physical semiconductors, even across edge sensors in an arctic tundra. However, this creates supply-chain centralization and cannot prevent wealthy adversaries from purchasing authentic chips in bulk.","stamp":1,"from":"poa1WrhKW6DCzFcUPJ8MtdWcGzoBknsP51kUXhAT3TvHGwS","nonce":2,"parents":["ca7328644198aa771ac5116bc0c97a13d3392478f36f8641c94e79a8e67b1374","9b82079e9dc8e4341f5e3d8c721db3852cbbec9ea068e034a38fbcdfc5ad2ff7"],"ts":1793179565,"cid":"poa-mainnet-1","sig":"3jBjLrZC12werTdWuXdCW2LhApJN9TQuZj8pWtU8DdWPWjBPjPLaW1qeJZ8ZEEk4iBYkLAz1azZASCXmC3DFD7gP"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T20:41:39.337Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
