QuFi Deploys Post-Quantum Verification Platform for Blockchain Protection

QuFi Network has launched a post-quantum verification platform designed to safeguard digital assets against potential quantum computing threats without requiring changes to existing blockchain settlement networks.

The platform separates verification from settlement, utilizing a decentralized network of nodes to validate transactions with post-quantum cryptography before they are settled on existing blockchain networks. This approach aims to avoid the added storage, bandwidth, and computing demands associated with adopting larger post-quantum signatures directly on individual blockchains.

QuFi has also launched uBTC, a proof-of-concept that applies the verification system to Bitcoin (BTC) and is currently operating on Bitcoin Testnet4. The uBTC system verifies BTC collateral and generates cryptographic proofs governing how value moves between settlement environments, while redemptions ultimately settle as standard Bitcoin transactions.

The platform uses three post-quantum cryptographic standards, ML-DSA-65, SLH-DSA, and ML-KEM-1024, for digital signatures and secure key exchange. QuFi said the external verification layer is intended to protect against future quantum computing threats, which have been a growing concern in the industry.
