This question already has an answer here:

I've been caught up in the post-quantum cryptography scene for a little while now, and understand that the RSA or ECC cryptography inherent in a cryptocurrency network can be easily broken by a sufficiently large quantum computer. I, however, have a more specific question...

The hashcash proof of work algorithm that is used by modern cryptocurrencies, is it vulnerable to quantum attack?
