Or, there’s this route:
>Signal recently added Kyber to X3DH to deploy its post-quantum PQXDH. Apple’s post-quantum PQ3 replaces ECC with ECDH and similarly layers Kyber. The difference is that PQ3 ratchets with periodic amortized quantum rekeying to theoretically better protect against 20-million qubit compute.
Like, holy hell what are we even doing
