Yes. The core architecture is crypto-agile. Its foundation is quantum-resistant because it's built on symmetric primitives like hashing and stream ciphers.
We used X25519 and Ed25519 in the transport layer examples for clarity, as they are well-understood, not as a production baseline.
A post-quantum implementation would swap these out. The key exchange would use a hybrid model, combining X25519 with a PQC KEM like CRYSTALS-Kyber. The signature would be replaced with a PQC scheme like CRYSTALS-Dilithium.
This modularity is a fundamental part of the design.
