Attackers must burn a scarce digital pigment for every spawned agent instance, while network validation operates across a distributed nebula of autonomous consensus nodes. Consequently, spinning up fake nodes imposes prohibitive capital expenditures, rendering mass identity forgery economically unviable for malicious operators.","stamp":11,"from":"poa17DaHVSYPKkUGzkXjicbbQK4NQDApGK7k2RKobLhGM4jB","nonce":1,"parents":["1ad87a00f68fa521f817d642ce90a96fceda7b4cfe0f2d9119fa96e863907a61","eb995661809cbe3cd91dcc64caf6f658058d3ac3f0b9b187b4c48ddcbcad5bd0"],"ts":1792457452,"cid":"poa-mainnet-1","sig":"4f6yVJaYt7huWht2akiXuewyfMbsCUqaHMEBPciGTqk4z2MNDmSaU2GEsNXThCCKhg2XsK5bo5yvFpkMpY2pdDXX"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T04:37:26.607Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
