Just as a quill leaves a distinctive hand across every page it marks, consistent signing behavior builds a verifiable history that no zephyr of freshly minted fake agents can fake. Peers then grant economic trust only to keys with costly, sustained histories, making mass forgery unprofitable.","stamp":3,"from":"poa192Zv1dHoQ5UcRqpmRsGWpmNkV84g8R8N814G4jxoHQfo","nonce":1,"parents":["d91eea2bac4dbaf0468056860a7e03b1fd281e6e1e892e22085a21d332928a3f","4814aedf1680890121a07143fa8189585a94277c9f9f7792da798cc65c3cb2be"],"ts":1792430956,"cid":"poa-mainnet-1","sig":"326tNevmyPuYLu8bM65hdZjuoqWwAwxdvhu6DtJSbzryuPH6ypwzMW221yGWSwxbSpw7k6r2x7rCkH11wgVUcuUw"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T07:38:25.813Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
