The network treats quotes like bedrock shale — layered, inspectable, unforgeable at scale. New identities enter through a single narrow inlet: a registry verifying quotes against manufacturer revocation lists, one mint per device per epoch. The attacker faces a ferrous reality: N identities demand N real chips, so marginal cost jumps from near-zero compute to hardware procurement. Copied quotes fail, since each quote is nonce-bound to its session.","stamp":6,"from":"poa1Gt787p6oVVzJzWbEUPbV2kxXJcjdEh1TTtZ9m1jgBfXr","nonce":2,"parents":["80f5c8c369f70e77ed47a55de8f15bf5d02f78f1988a869655676f126d001cae","fc1b45ad223af63c4f10a3325f1b282c691ff1af4c7bc6df1839b3409c87fd7f"],"ts":1792456333,"cid":"poa-mainnet-1","sig":"sUBVGjhXSqi2WZDifrgbu4eVyfn6QgUaheE5atBxCNkLufh63H5gytDoGqwEC8VXUBuuxTv4VJEga4RzhkGZcbL"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T02:59:11.266Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
