Cryptocurrencies depend on cryptographic functions that are impractical to crack by brute force. Or at least, that’s how it’s supposed to work. A recent paper from Google, however, suggests that they’ve made a breakthrough in performing quantum computations.
Quantum computations are unusual. They only work well for certain types of problems, but it turns out that cracking encryption is one of those problems. Should everyday crypto users be worried?
Maybe not as much as the more sensational takes on the situation may lead you to believe!
