QuFi Network Limited has launched a platform designed to verify digital asset transactions using quantum-resistant cryptography without requiring changes to the blockchain networks that settle them.
The Hong Kong company said in a news release that its QuFi Platform separates cryptographic verification from settlement, the process that completes a transfer of value. Its approach assigns verification work to a network of independent computers, which generate proofs that participating financial systems and blockchains can check before allowing transactions to proceed.
The company is targeting a potential cost of adopting post-quantum cryptography, the mathematical methods designed to withstand attacks from future quantum computers. Depending on the method and implementation, the digital signatures used in these systems can be more than 100 times larger than widely used elliptic-curve signatures, according to the release. Larger signatures can increase storage, bandwidth and processing requirements.
QuFi’s proposal is to share that verification workload across networks. Rather than have each blockchain handle the work separately, its platform would perform the checks and provide compact proofs to the systems responsible for settlement.
“Digital finance has spent the last decade building settlement infrastructure. The next decade will require verification infrastructure. We believe verification should exist as a neutral layer that sits above blockchains, assets, and financial systems, delivering cryptographic certainty before value moves. That is the problem the QuFi Platform was created to solve,” said Alexander Reay, QuFi’s co-founder and CEO, in the statement.
The release describes a working demonstration on Bitcoin’s test network but does not provide performance benchmarks, independent security assessments or details of production deployments. Those omissions leave the platform’s efficiency and security claims difficult to assess from the announcement alone.
QuFi Bitcoin Demonstration
QuFi developed a proof of concept called uBTC to demonstrate how the architecture could work with Bitcoin collateral. The system verifies that collateral and generates cryptographic proofs governing transfers across participating settlement environments, according to the company.
QuFi said the complete process is operating on Bitcoin Testnet4, a testing environment. The demonstration covers minting, burning and redemption — creating tokens, removing them from circulation and redeeming them for the underlying collateral.
These events are governed by verification challenges using two post-quantum digital signature systems. Redemptions ultimately settle through standard Bitcoin transactions that can be independently checked on the blockchain, the company said.
That distinction matters to the scope of the announcement. QuFi is proposing an additional verification layer while retaining Bitcoin’s existing settlement architecture. The release does not establish that adding this layer makes every part of the underlying blockchain or transaction process resistant to quantum attacks.
Security Architecture
The platform combines ML-DSA-65 and SLH-DSA for digital signatures with ML-KEM-1024 for establishing shared secret keys. Digital signatures help establish that an instruction is authentic, while key encapsulation supports secure communication.
The technologies fall under three post-quantum cryptography standards finalized by the U.S. National Institute of Standards and Technology in August 2024. QuFi said combining different cryptographic approaches is intended to provide resilience across multiple families of security methods.
The company’s broader argument is that digital finance could benefit from the division of responsibilities found in traditional markets, where specialized systems handle functions such as trading, clearing and settlement.
Under QuFi’s proposed model, verification occurs before settlement, and the resulting proof can be checked by multiple downstream systems. Whether that structure reduces costs at scale will depend on its implementation and adoption; the release does not quantify expected savings.
Alongside the launch, QuFi opened applications for its Genesis Node Program to recruit independent operators for the verification network. The program targets infrastructure providers, institutional custodians, enterprise partners and organizations working with Ethereum-compatible systems.
QuFi said it plans additional integrations with Ethereum-compatible ecosystems, Stellar, Solana and broader financial infrastructure. The announcement presents those integrations as planned work rather than completed deployments.
The company also said it is seeking strategic partners and investors through an ongoing seed financing round to support network development and institutional integrations. It did not disclose a fundraising target, valuation or committed investors.
