Meet the quantum blockchain that works like a time machine

By John Biggs

A new – and theoretical – system for blockchain -based data storage could ensure that hackers will not be able to crack cryptocurrencies once we all enter the quantum era. The idea, proposed by researchers at the Victoria University of Wellington in New Zealand, would secure our crypto futures for decades to coming using a blockchain technology that is like a time machine.

To understand what’s going on here we have to define some terms. A blockchain stores every transaction in a system on what amounts to an immutable record of events. The work necessary for maintaining and confirming this immutable record is what is commonly known as mining . But this technology – which the paper’s co-author Del Rajan claims will make up “10 percent of global GDP… by 2027” – will become insecure in an era of quantum computers.

Therefore the solution is to store a blockchain in a quantum era requires a quantum blockchain using a series of entangled photons. Further, Spectrum writes: “Essentially, current records in a quantum blockchain are not merely linked to a record of the past, but …read more
