Years ago I read about the potential danger of quantum computing for Bitcoin, I'm aware that before bitcoin gets **** up, many other things like banks and governments get fucked up earlier. However, I was wondering if anything changed in the last few years and whether quantum computing has progressed lately. Is it still a threat, will there be a solution? Thanks!
Not much has changed, but yes to both: It is a threat, and a solution has been planned for long, they just take their time (core devs) to implement it...
I expect the first with capacity to attack would be large institutions, such as those funded by governments... Because the early computers are so big, not unlike classic computers of the past, they need a building and are very crude compared to what is expected to come yet.
