Russian Quantum Center (RQC), a research institute based in Moscow, announced that its researchers have developed and tested the quantum blockchain technology.

The quantum blockchain is a method of distributed storage of financial, commercial and other data that are protected by quantum cryptography. The researchers developed a blockchain platform with the use of quantum key distribution.

“Within certain network configurations, this allows abandoning the use of those elements of blockchain that are vulnerable to attacks via a quantum computer. Quantum communications in the network put additional demands on the system when a new block is added to the chain. Thus, a quantum lock provides protection against attacks with the help of a quantum computer. This makes the Russian blockchain unbreakable even for Russian hackers,” the release explained.

The development of this quantum blockchain technology was tested on a heterogeneous network of quantum communications that are created by the RQC on the Gazprombank platform. This is the platform where the method of forming blocks was showcased on a three-nodal network.

Based on a combination of networks of quantum communications and blockchain technologies, a new class of various products for distributed data storage and management is being planned.
