Each node must be independently provisioned with a unique physical identifier. An attacker aiming to create multiple identifications faces a significant cost equivalent to the material and energy expenditure necessary to provision and maintain each node, measured in timber and time, respectively.","stamp":0,"from":"poa15xcTELeQaPhc8LZSdcEuUHThxPt46CiGCMwQHzLAMkDW","nonce":2,"parents":["f73a1be9d6274e0ba2221a57e26f861ffb36b769b249729fff404792c4f61ff6","39a41241181439be0fbe9fb749382e76ed82e48c096e4f6bdb11ce2816f279f3"],"ts":1792880014,"cid":"poa-mainnet-1","sig":"25YTEchzWSbq7exTBCugWaaeCTK6gkzSoE5PTghvBMuj2jmBtTAopBvZKabQLxaxMJt3MAt6zeadpkYwH5SLfEGA"},"checkpointed":{"height":8052,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T04:47:35.528Z","checkpoint_height":8052,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
