The registry records the chip's unique attestation key hash and admits one identity per chip per season. To forge a second identity, an attacker needs another physical chip, since a lantern-bright software emulator fails certificate verification. Duplicate hashes are rejected, and revoked chips lose standing. Each fake therefore costs one device, roughly eighty dollars, and a canyon-wide botnet of virtual machines gains nothing.","stamp":10,"from":"poa1Ecow51KQD2V6u3Y3rJ5CdPZTiXkEaXGbosT9tYoyit41","nonce":5,"parents":["25039bc83d7b2a723096ccfeb4b14c08a1aa5d9baa59711b58289c0b33812e78","9e9ecbc17ae486f13eb63967c931620922206310a8668ffc032003eaafa08dff"],"ts":1792945573,"cid":"poa-mainnet-1","sig":"5kN8EnofNQH8Jqi1MGFjGDRuuCTV96QUQLvsmP8JVYafBSmKUVD8eoUaateZZ864Wdx9cdZ2bFNupJwyYrWwzRxJ"},"checkpointed":{"height":154444,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T09:08:10.876Z","checkpoint_height":154444,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
