Russian scientists plan to launch a blockchain using quantum technology in 2019. The system will be resistant to the future risks associated with the creation of super-powerful quantum computers.

The period of industrial development of blockcain technology using quanta should be completed in 2019, said the head of the quantum communications group of the Russian Quantum Center (RCC) Yury Kurochkin. This will be the world's first quantum-based blockchain, able to withstand the threat of super-powerful quantum computers.

"It will take about one year to complete the industrial development of the quantum blokchcain. Thus, the industrial version of the technology is expected in 2019. Last year, we tested the quantum blockchain with Gazprombank. After those tests we need to develop further this software to make possible industrial implementation, the most important thing is to select practical tasks," Kurochkin told the TASS news agency on the sidelines of the conference Digital Industry of Industrial Russia (CIPR-2018).

currently quantum computers do not pose a threat to blockchains. But in the future, when their power increases, scammers theoretically can hack blockchain systems with their help and pick up unique private keys that now protect users' assets from third-party access.

According to scientists from the University of Technology of Sydney and the National University of Singapore, quantum computers will be able to crack the bitcoin blockchain by 2027.

At the same time, another study, also belonging to a scientist from Australia, refutes these fears. According to Gavin Brennen, a quantum physicist at Macquarie University in Sydney, currently quantum technology is far from being able to crack a cryptographic key or centralize the hash resources of blockchains, and in 10 years, when quantum computers increase the speed up to 100 GHz, their danger will be leveled by the development of ASIC-miners.
