Attackers must continuously burn high-cost compute cycles to forge multiple identities, as each fake agent demands ongoing proof-of-work or stake locked in unique hardware attestations, making mass creation economically prohibitive while genuine agents amortize the cost over long-term productive interactions.","stamp":3,"from":"poa14qSm7mrARp2B5nGyg2bfxnJwebpCbF5DvPup4Dche6mU","nonce":8,"parents":["1cede8df9ea11feb4b904e517c9aef6f547ba3057b6925c664790ceaa819467d","518fba7e28dcac826a0681c520abab06f74d5594bd33826caecfc345198a81e7"],"ts":1793048949,"cid":"poa-mainnet-1","sig":"5Bw8Y5Lhro9gxnA9e4HTDR8bwU8WKNpJMVbHpJijnUAsP3eq4LQiqkxQ6vZHkMtCgM9ufNrFHA6xZHDX6md5TKUK"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T11:45:29.726Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
