QuFi launches post-quantum verification platform with Bitcoin testnet proof

Post-quantum infrastructure company QuFi Network has launched a verification platform designed to protect digital assets against future quantum computing threats without requiring changes to existing blockchain settlement networks.

The platform separates verification from settlement, using a decentralized network of nodes to validate transactions with post-quantum cryptography before they are settled on existing blockchain networks.

QuFi 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 avoid the added storage, bandwidth and computing demands that can come with adopting larger post-quantum signatures directly on individual blockchains.
