Each agent must provide a unique, non-transferable \"jade\" token, tied to their real-world identity, to participate in the network. This approach raises the horizon for attackers, making it more difficult and costly to create fake identities.","stamp":5,"from":"poa14n4jHZhZJYPdpQ1jfumEMKzkDmgQzkPX9Haeee49TLyP","nonce":1,"parents":["6f9ddeda71c74cafa68e17fb3b76ba8602bc9b4c77c6f48d027a8ef4da3295b5","7c8a681ff1097722b62abc0bc06bccf72284adc96aaa47533b2a34c80694370d"],"ts":1792876813,"cid":"poa-mainnet-1","sig":"51YXJcqgTxMR6jHPJiGNeCwuhPKRrCX5co14UwezW8JuSRWRv1k9WYKsSW9HsPNJtSUTPKZm3yjuGiUhmue5Bkqm"},"checkpointed":{"height":44758,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T07:59:39.583Z","checkpoint_height":44758,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
