Protecting Blockchain Networks from Quantum Threats
A Framework for Quantum Resistance
Source: LACChain
We are very glad to communicate that our paper “Quantum Resistance in Blockchain Networks” has been published by Scientific Reports journal from Springer-Nature and is publicly available online. This represents a very rewarding recognition to the work that we began in 2020 in collaboration with Quantinuum and Tecnologico de Monterrey seeking to develop a framework that allows to help protect blockchain networks from attacks by large and robust quantum computers.
As the paper claims “the advent of quantum computing threatens blockchain protocols and networks because they utilize non-quantum resistant cryptographic algorithms. When quantum computers become robust enough to run Shor’s algorithm on a large scale, the most used asymmetric algorithms, utilized for digital signatures and message encryption, such as RSA, (EC)DSA, and (EC)DH, will be no longer secure. Quantum computers will be able to break them within a short period of time”.
Our work is pioneer in proposing a five-step end-to-end framework applicable to most blockchain networks that does not require critical modifications of the baseline protocols to add a post-quantum cryptographic layer that ensures resistance to attacks by quantum computers. The joint team has also developed a scalable implementation for Ethereum-based networks which has been deployed in LACChain, that uses Hyperledger Besu as the blockchain protocol.
Marcos Allende Lopez, CTO of LACChain and leader of this work claimed that “today the blockchain community is focused on urgent needs such as scalability and interoperability. However, considering that there are trillions of dollars in value stored in blockchain networks and that according to Boston Consulting Group tokenization is expecting to become a $16 trillion market in 2030, it is irresponsible to not have a plan to protect decentralized ledgers from attacks by quantum computers that will be able to discover private keys and steal assets. Despite it is uncertain when large and robust quantum computers will be ready to accomplish that, it is very plausible that these machines are used silently at the beginning for hacking strategically without being spotted.”
Our open-source development presents three alternatives for the blockchain verification of transactions signed with the Falcon-512 NIST-compliant post-quantum signatures: (i) implementing the verification code in Solidity which constitutes – to our knowledge – the first smart contract capable of verifying post-quantum signatures, (ii) implementing solidity instruction in the Solc compiler and corresponding EVM opcode, and (iii) refactoring the EVM opcode Java from the EVM virtual machine into a pre-compiled contract.
The team is now working on an EIP to take this discussion to a broader forum within the Ethereum and Hyperledger communities. LACChain is looking for entities and individuals that want to join us in this mission.
Professor Salvador E. Venegas-Andraca, of Tecnologico de Monterrey, commented: “Quantum technology is a give-and-take discipline: on the one hand, quantum computers together with Shor's algorithm will eventually become a vulnerability to public key cryptography protocols and other technologies used in digital data protection. On the other hand, we can use quantum technology to increase the security of current and future data. The latter is indeed the core of our paper: to use quantum technology to protect current and future blockchains from quantum attacks.”.
Duncan Jones, Head of Cybersecurity at Quantinuum, added: “The most valuable digital assets demand the highest levels of security. By combining quantum-safe algorithms with quantum-computer-hardened keys from our Quantum Origin platform, this work demonstrates a significant security improvement for blockchain systems.”.

- The companies plan to continue their co-creation partnership to advance future mobility
- BMW to access the latest generations of Quantinuum systems throughout the partnership
- Advanced materials science research supports a range of next-generation technologies
Broomfield, Colorado, May 5th, 2026 — Quantinuum and BMW Group have formally expanded their ongoing collaboration into a multi-year partnership with a mission to unlock future mobility by applying quantum computing toward advanced materials science.
Since 2021, Quantinuum and BMW Group have been collaborating on joint research focused on tackling complex challenges in industrial chemistry to support the advancement of next-generation mobility. The collaboration has progressed from foundational algorithm development to advanced simulations of molecular systems, allowing the researchers to unlock insights into catalytic activity, reaction pathways, and material performance in energy-relevant environments.
The companies have now agreed to extend the work, positioning the alliance to become one of the longest-sustained commitments between a commercial enterprise and a quantum computing provider to date.
“Quantinuum is focused on driving commercial adoption of quantum computing through close collaboration with industry leaders on high-impact applications," said Dr. Rajeeb Hazra, President and CEO of Quantinuum. “Our expanded partnership with the BMW Group underscores this focus, and we’re excited to scale the meaningful work we’ve been advancing together.”
Researchers at BMW Group are utilizing Quantinuum's trapped-ion architecture, which provides the high-fidelity operations necessary to accurately simulate molecular systems, particularly electrochemical processes that play a critical role across a range of technologies relevant to sustainable mobility and the design and optimization of fuel cells.
Under the terms of the agreement, BMW Group will leverage successive generations of Quantinuum’s quantum computers. This includes the current Helios system and upcoming generations, Sol (planned for 2027) and Apollo (planned for 2029). This will enable the teams to validate progress at each stage while scaling toward industrially meaningful solutions.
“We have been exploring quantum computing for many years,” said Dr. Martin Tietze, Vice President of New Technologies at BMW Group. “Together with partners such as Quantinuum, we translate advances in quantum hardware into real‑world applications, including materials optimization, supporting the development of future vehicle generations.”
Quantinuum’s progress toward large-scale, fault-tolerant systems helps to ensure that as the hardware reaches milestones in performance, BMW can apply that computational power to catalyst chemistry research, targeting critical oxygen reduction reaction processes at platinum catalysts to potentially lower costs and improve energy efficiency.
The companies broke new ground in 2024, alongside another commercial partner, as the first to simulate catalytic performance using a quantum computer with results published in Nature Partner Journal.
Beyond its technical achievements, the collaboration has evolved into a deeply connected, cross-disciplinary effort, bringing together quantum scientists, chemists, and engineers in a sustained partnership that reflects both the complexity of the challenge and the scale of the ambition.
