Quantum computing’s threat to cryptography has been a theoretical problem for years. QuFi Network Limited just treated it like a practical one.

The company launched its QuFi Platform on September 4, 2026, introducing a post-quantum verification layer designed to sit on top of existing blockchain infrastructure rather than replace it. The first live demonstration used Bitcoin’s Testnet4, walking a synthetic Bitcoin token called uBTC through a full lifecycle: minting, burning, and final redemption, with the redemption settling as an ordinary Bitcoin transaction.

The key distinction is what didn’t happen. No changes were required to Bitcoin’s underlying protocol. The quantum-resistant verification layer operated independently, generating compact cryptographic proofs that downstream systems can read without any modification to the settlement network itself.

How the cryptography actually works

QuFi’s hybrid architecture pulls from three NIST-standardized algorithms. ML-DSA-65 handles digital signatures. SLH-DSA functions as a hash-based backup layer. ML-KEM-1024 manages key encapsulation, the process of securely exchanging the keys that lock and unlock encrypted data.
