QuFi's Post-Quantum Verification Platform Aims to Protect Digital Assets

QuFi Network has launched a verification platform that protects digital assets from potential quantum computing attacks without forcing users to upgrade or fork existing blockchain settlement layers.

The approach, according to QuFi, separates 'verification' from 'settlement,' so that transactions can be validated with post-quantum cryptography while value is ultimately settled on familiar networks.

Alongside the platform, QuFi introduced uBTC, a proof of concept that applies the verification system to Bitcoin collateral. uBTC is currently running on Bitcoin testnet, with redemptions designed to complete as standard Bitcoin transactions after the verification step produces cryptographic proofs that govern how value can move between settlement environments.

QuFi's platform validates transactions using post-quantum cryptography before settling them on existing blockchain networks, avoiding direct post-quantum signature deployment on-chain. The company's stated goal is to reduce potential increases in storage, bandwidth, and computation that can come with using larger post-quantum primitives directly within blockchains.

QuFi's verification-layer approach is positioned as one way to reduce the integration costs of post-quantum methods into mainstream blockchain transaction flows. The company uses three post-quantum cryptographic standards, ML-DSA-65, SLH-DSA, and ML-KEM-1024, to handle signatures and secure key exchange.
