The Device List Is the Certificate: Post-Quantum Identity Proofs at a Fifth of the Size, Without Inventing Anything
An ML-DSA-65 signature is 3,309 bytes. On the hardware we build toward, that is a line item on every connection. We cut a 5,440-byte device credential to a 1,024-byte inclusion proof by publishing the fleet's enrollment list as a Merkle tree, the same structure Certificate Transparency has run since 2013 and the one the web PKI is now adopting. Nothing in the cryptography is new. That is the feature.
