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!
There have been several threads about this over the past week due to Google's recent claims of "quantum supremacy." Read up:
Google Claims Quantum SupremacyQuantum supremacy and Satoshi blocksGoogle Says That They Have Just Reached Quantum Supremacy - BITCOIN IN DANGER?The TL;DR version is that this "achievement" is insignificant and Bitcoin's security is not at risk. Quantum computing may
never be a real threat. If it is, we probably have a good decade or so to figure out what to do.
Besides Bitcoin can always fork to become a quantum computer resistant before that threat happen.
That's the easy part. The difficult part is dealing with the millions of bitcoins that will reenter circulation from bitcoins sitting in vulnerable addresses.
