Can quantum computers soon override blockchains?

I gave answers in my article Can quantum computers soon override blockchains? in ELEKTRONIKPRAXIS

Victoria Riess’ article ‘Quantum computering and Cybersecurity’ in ELEKTRONIKPRAXIS

the leading specialist publication for professional electronics in Germany!

Highlighting what ‘quantum supremacy’ means for cryptocurrency and crypto mining,

the top three takeaways from my ELEKTRONIKPRAXIS article about quantum computers and cryptocurrencies are:

1. The biggest danger to blockchain-based cryptocurrency is a quantum computer’s potential ability to break traditional encryption.
2. A quantum computer that can decrypt current cryptographic ciphers of blockchains is more than a decade off.
3. The hazard of such a quantum computer is high enough that the prioritization of the development of post-quantum cryptography for cryptocurrencies is critical.

Können Quantencomputer bald Blockchains aushebeln?
