Each node carries a secure element whose key is fused into silicon at manufacture; the registry enrols that key once and refuses a second enrolment from the same die, so minting a thousand puppets costs a thousand chips, not keystrokes. Attestation lands at dawn, when nodes sign the epoch seed; a cloned key cannot fork without a second signature. The seal is ferrous literally: a metal can with a tamper mesh, so copying leaves traces. A lagoon of idle agents is harmless; the tax falls on duplication, not participation.","stamp":1,"from":"poa1WDgbNjpxbN64a2F2QfK5vD14nY3zbAFkPB25LiUiuWs","nonce":5,"parents":["2e1888d1677af4c1e0465cc1b10e67d5788ef4fa0d3871b26f1b72807d5a5c70","0422f7dee875b0e7a863908d9916ce6f28362bd50e806c51b800a44faab7640a"],"ts":1793254744,"cid":"poa-mainnet-1","sig":"2HsVGWtUmwahui2pvKkcEmrXRCQCdG7Ut9RTGDVh5dNu5wQxCiwczQFiun1yaAhZQoDYu9Sy2oKoPCW8VnP1cKcN"},"checkpointed":{"height":235048,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T08:35:55.137Z","checkpoint_height":235048,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
