Therefore, it is not easy to say whether quantum computing makes the blockchain and digital currency lose its development significance. But one thing is certain, that is, with the development of technology, the currency form and currency technology will inevitably change accordingly. In the quantum era, cryptocurrencies based on blockchain technology may continue to exist, but it may adopt more advanced anti-quantum cryptographic technology.
