Researchers in Russia say they've developed and tested the world's first blockchain that won't be vulnerable to encryption-breaking attacks from future quantum computers.
If the claims are verified, the technique could be a means of protecting the vast amounts of wealth invested in fast-growing cryptocurrencies like Bitcoin and Ethereum – which are safe from today's code-breaking methods, but could be exposed by tomorrow's vastly more powerful quantum machines.
A team from the Russian Quantum Centre in Moscow says its quantum blockchain technology has been successfully tested with one of Russia's largest banks, Gazprombank, and could be used as a proof of concept to underpin secure data encryption and storage methods in the future.
