Each agent must submit cryptographic meter signatures showing dedicated electrical draw—such as from shale gas or municipal grids—fed through copper wiring. The consensus kernel validates this expenditure before granting credentials, imposing a scarce kilowatt-hour cost per replica. However, this mechanism encourages environmental waste and disadvantages low-resource participants.","stamp":3,"from":"poa1FcYUUH8q7bzuFKaKJ6cr1upwJqZywu6DHrXEfnSPw3Gh","nonce":10,"parents":["169b494fe2cc7e4fcfec5be1151569e203219edcadea0c2a150898ca83c46011","f9d4755fbab32c8b90cede7c4f3876fd6e8684a02e3465b3aa447b3ac27a7675"],"ts":1793239639,"cid":"poa-mainnet-1","sig":"FT3R2nPjhY9KQd13NmPqvn4ARZSktwnus3EMoUtvLittioBgVtSVZdWtumaRhAQKbYHkDF9wwRaqpKdKC5gXN4A"},"checkpointed":{"height":226609,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-02T22:56:49.942Z","checkpoint_height":226609,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
