Russia Develops Tools for Quantum-Resistant Blockchain Systems
Researchers from Innopolis and Sirius have developed a suite of tools designed to protect blockchain platforms from future quantum attacks. The solution enables the use of cryptographic methods resistant to the power of quantum computing, which threatens today’s security standards. The development makes distributed ledgers more resilient and prepares digital infrastructure for the challenges of the quantum era.
A Secure Foundation
The development is based on quantum annealing and a modernized Potts model, allowing the algorithm to process problems in QUBO or Ising formats. This approach significantly reduces the time required to find exact solutions compared with traditional methods. The system can quickly identify optimal solutions in multidimensional spaces with an extremely large number of possible combinations.
The innovation provides a high level of protection for the national digital environment and critical infrastructure against prospective quantum threats. It serves as a reliable foundation for building domestic platforms with maximum cryptographic resilience. Integrating these tools into government projects and the digital economy supports Russia’s push for technological sovereignty in secure distributed ledgers, ensuring long-term security and independence of national information systems.
Quantum-Resistant Cryptography
The projects are primarily aimed at the domestic market, but they also have export potential for integration into international security systems. Russian post-quantum solutions are positioned to protect critical information infrastructure abroad.
The practical component of the project is structured around two main directions. The first is the optimization tool Sirius-Q. QUBO Solver, which makes it possible to model blockchain network resilience to quantum threats and design effective protection schemes. The second is the post-quantum cryptographic primitives Sirius-Q. KNAA-2-EDS, a set of digital signatures based on highly robust mathematical algorithms. These are intended to replace classical schemes such as RSA and ECC, which are vulnerable to quantum computing capabilities.
Deploying such solutions lays the groundwork for a broad transition to quantum-resistant cryptography. This is particularly relevant for sectors with stringent data security requirements, including finance, government services, and the digital economy as a whole.
Global Context
Similar trends are emerging worldwide. One example is QANplatform, a hybrid layer-1 blockchain platform designed to be resistant to quantum attacks. Launched in 2021, it targets quantum-secure applications, including smart contracts and decentralized applications, in response to the growing risk posed by quantum computing to blockchain security.
Globally, the development of hybrid quantum-resistant solutions for blockchain and federated learning increasingly relies on post-quantum cryptography algorithms such as CRYSTALS-Dilithium. One example is a prototype post-quantum wallet developed by the startup ChainReaction, designed to remain compatible with existing blockchain networks while resisting quantum attacks.
As of August 2025, researchers in Innopolis had developed post-quantum algorithms and cryptographic primitives to protect digital platforms from quantum-related threats. These include a secure environment for cryptographic operations, a tool for automated improvement of cryptographic structures, a chaotic sequence generator, and other components.
Work on quantum resilience for blockchain systems is underway globally, including in Russia. Developing domestic technologies in this field is considered critical for maintaining national technological independence and for effective participation in shaping future international information security systems.
A Strategic Priority
Building Russian capabilities for quantum-resistant protection is treated as a strategic priority. The anticipated emergence of powerful quantum computers threatens the reliability of modern cryptosystems. Integrating such developments into state digital infrastructure is expected to reinforce technological sovereignty and significantly increase trust in national IT platforms.
Over the next three years, developers anticipate a phase of active testing and the launch of pilot projects at the federal level, along with the creation of government standards for post-quantum encryption. In the longer term, these solutions could be adapted for export and integrated into international security protocols and cryptographic standards.
