Cryptocurrencies are secured by a technology called public key cryptography.
But makers of quantum computers are working hard to address those shortcomings.
That could substantially increase the amount of computing horsepower needed to house blockchains.
But it presents a conundrum in the crypto community, which often rejects the idea of authority.
That’s likely to be fixable with more-modest technology updates, though.
Thecryptocurrency walletspeople use to keep track of their digital assets could also be vulnerable to quantum computing.
These wallets store private keys people need to access their assets recorded on the blockchain.
A successful attack could empty a wallet.
“How do you force users to upgrade keys?
