Ethereum Won't Hide From Quantum Computers Behind PoS Shield

[Altcoin1998$]

Quantum computing has long been regarded as Bitcoin (BTC)’s ‘bogeyman.’ The popular fear is that, as secure as Bitcoin and other proof-of-work cryptoassets are in terms of standard cryptography, quantum computers could provide additional means of breaking them.

One other popular assumption is that, because they don’t use PoW, proof-of-stake cryptoassets such as Cardano (ADA), Polkadot (DOT), and Tron (TRX) (and eventually, Ethereum (ETH)) aren’t as vulnerable to quantum computing attacks as networks like Bitcoin, Bitcoin Cash (BCH) and Litecoin (LTC). However, according to a variety of computer scientists and crypto experts, it’s not the consensus mechanism of a coin which creates the biggest risk in terms of quantum computers, but rather the signature system.source

Thanks for sharing such an interesting article. Quantum computers are not a threat to cryptocurrencies, at least not yet, these computers are still in a state of theory, as there is no 100% working prototype yet. When they are in full operation, access to these machines will be very restricted, so later the cryptocurrency algorithms could be updated so that they are not affected.
