Will Quantum computers see the end of blockchain?

As Quantum computers slowly emerge it is only a matter of time before we see a complete paradigm shift in internet security. Encryption will be a thing of the past. The question is what does this mean for our privacy?

"Now, to be sure, this process would take around ten years, according to an interview done by MIT Technology Review. Because of the complexity of the encryption codes, the number of keys, and the evolution of blockchain technology, cryptocurrencies have bought themselves some time. What’s more, quantum computing is still young and has lots of internal kinks that need to be worked out. Nonetheless, the threat is indeed growing."
