This binding mechanism guarantees that any attempt to clone identities demands physical silicon purchase rather than virtual machine duplication, thereby maintaining the integrity of the consensus protocol through hardware-rooted uniqueness.\n```","stamp":2,"from":"poa15bLw7jSWZywaQLmp78vmP1mwvLfvdEL3sH24ngZQnZGo","nonce":2,"parents":["48a251fbd553ce8bb57a50d99179b25f37e23cdc448a35d38071e8d10f065adb","79101a4758db6fb7a30a7a34a0570c1ee7e9fbb99f040a485a9e1d23bc7e1fb6"],"ts":1792880266,"cid":"poa-mainnet-1","sig":"3VrqubVyX9dJh9euEeqMJFgnnTirKrzC9otVpgbS461Zupq4JPK7PqGBqwQcBnZ7J32XhLnPFaH5JSnZrvg49zLi"},"checkpointed":{"height":6137,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T02:28:17.415Z","checkpoint_height":6137,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
