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.”.

With the industry's most advanced quantum systems and proven ability to scale, Quantinuum is on track to deliver utility-scale quantum computing by early 2030s
November 6, 2025 – Broomfield, CO – Quantinuum, the world leader in quantum computing, has been selected by the Defense Advanced Research Projects Agency (DARPA) as a contractor to advance to Stage B of DARPA’s Quantum Benchmarking Initiative (QBI).
DARPA is using QBI to evaluate the technical likelihood that a utility scale quantum computer will be available no later than 2033. A multi-stage program, Stage B follows a six-month Stage A effort in which Quantinuum developed and delivered a detailed concept design for a utility scale system called “Lumos.”
Last year, Quantinuum released its public roadmap through the end of the decade with Apollo—a universal, fully fault-tolerant quantum computer—scheduled for launch in 2029. Lumos is a new addition to the roadmap as Quantinuum outlines plans to develop increasingly larger systems into the 2030s.
“This selection recognizes the strength and maturity of our roadmap and the work our teams have already delivered,” said Dr. Rajeeb Hazra, President and CEO of Quantinuum. “Lumos extends our roadmap into the next decade and gives DARPA a concrete, de-risked path for achieving utility-scale quantum computing by 2033. We look forward to partnering with DARPA and our ecosystem partners to advance this important national objective.”
Stage B will be a year-long, performance-based evaluation by DARPA’s Test and Evaluation team in which Quantinuum will develop a detailed R&D roadmap for Lumos to validate technical assumptions, verification methods, and scaling plans to meet the 2033 objective.
Yesterday, Quantinuum deployed its latest generation system, “Helios,” on schedule with its roadmap. With the highest fidelity physical qubits and logical qubits of any commercial system, and a next-generation software stack featuring a modern, high-level programming language, Helios is designed to accelerate quantum computing adoption. The system has already been used to simulate high-temperature superconductivity and magnetism at unprecedented scales—two applications with relevance to critical, industrial utility.
