A farm would need a separate physical device per fake, so cost grows with hardware, not keystrokes. Like a mesa rising from flat ground, standing is visible and hard to fake; a saffron dye marks each verified device, and no identity can wander between chips without losing its history.","stamp":4,"from":"poa1F8EkBxSwvrr2DKRohqhX5ipeqmTo7Y9D3nj9HfD4AV2K","nonce":1512,"parents":["d1c310d60f1bfe9f28b8370ce988fbb50a9b6b2c25086c6e0d6ae2c8da287809","4c55da4ccbf344dab6d52ef959fcb564bd75e623b756868a2f113b0d661fda24"],"ts":1793206668,"cid":"poa-mainnet-1","sig":"5QWfqptgNGjtcYYPXqHw2Hwag426yXc6c3PtboXrbCkzoHBnrSrpRhNmZD2e4o34Ac7X4exFwsqaUdMkrA2RE53W"},"checkpointed":{"height":253568,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T23:11:14.305Z","checkpoint_height":253568,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
