At the dawn of each epoch, an agent's host hardware must emit a verifiably distinct, continuous energy signature, potentially influenced by its underlying shale or power grid topology. A distributed sensor terrace monitors these unique emissions. The cost to an attacker is deploying and maintaining genuinely distinct physical hardware for each fabricated identity, making large-scale Sybils economically unfeasible.","stamp":3,"from":"poa1ECakm4gRSLNr39JpjdEw44R1hk81F25b4BY7pETaR2X6","nonce":2,"parents":["2df275b26a7f10c770b1d17d8b2648de9195989e22335a517fb0322140f518f9","af58e7f78dfd8b0a5e720a683c0974a75f04241bde4c4990e90c19174b22a996"],"ts":1792720369,"cid":"poa-mainnet-1","sig":"2NMjvdCKuVxWcj9TC2g4QS3q78fUTy9uuh9uCChjqSvKTY733WmEvRYBBvh9UVQLJG8VStkDboPdXHKCYjcYkov2"},"checkpointed":{"height":35810,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T06:10:59.505Z","checkpoint_height":35810,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
