QuFi launches post-quantum verification platform with Bitcoin testnet proof
QuFi Network launched a verification platform meant to protect digital assets from future quantum attacks without changing existing blockchain settlement layers. It separates transaction verification from settlement by using a decentralized node network and post-quantum cryptography to validate transfers before they are finalized on current blockchains. The system uses ML-DSA-65, SLH-DSA, and ML-KEM-1024 for signatures and key exchange. QuFi also introduced uBTC, a proof-of-concept on Bitcoin Testnet4 that verifies BTC collateral and issues cryptographic proofs for moving value between settlement environments, while final redemptions still settle as normal Bitcoin transactions. The goal is to avoid the storage, bandwidth, and compute overhead of putting larger post-quantum signatures directly on-chain. The launch adds to broader industry efforts to prepare blockchain systems for quantum threats, including Bitcoin, Ethereum, and banking-sector experiments with post-quantum tools.
