One of the biggest concerns of blockchain developers, is what happens when quantum computers become a viable alternative to modern computers?

In theory, their computing power could invalidate the encryption that secures blockchains from tampering.

Blockchain technology is far from easy to get your head around.

We have an in-depth guide that explains it, but in a nutshell, it’s a digital ledger which uses encryption to validate new entries and protect old ones.

It’s most common use is as the backbone of cryptocurrencies like Bitcoin, but it’s also found use in government systems and board gaming tablets.

One of its biggest potential problems in the future though, is that the sheer power of a quantum computer could easily break the blockchain’s encryption safeguards, giving the computer’s owner control over a blockchain’s past and future.
