Quantum will kill all hash functions. the thing is we are still > 10 years from home quantum. Currently, it only works in the lab near absolute 0
edit: I a word
I just thought ... If quantum computing represents a potential problem, can it also be a possible solution to scaling problems?
not "10 years from home quantum" but "10 years from quantum being a treat for bitcoin"
and we all know how accurate are 10-years predictions. If you tried to program a quantum computer only once, you know it's never gonna happen.
