"ha ha quantum computing is going to destroy all crypto soon!"
Ya ok if quantum computing is truly capable of breaking sha256 you can also kiss your banking goodbye and pretty much everything online goes to total shit as the integrity is toast. But keep hoping quantum computing can break everything lets just see how that plays out for humanity
We just go to sha512, then sha1024
Yeah, from what I've read, anything symmetric is at best subject to the rate of improvement over classical computing defined by Grover's algorithm, although there are multiple paths now. Asymmetric is a different story, but this is mitigated when public keys are not directly exposed themselves (until the very last moment) (e.g. Bitcoin) and PQC.
Facts
Check out surmount.systems people already working on quantum encryption paystring addresses. https://youtu.be/lFBq6PssP40?si=cztHXP8j0zGSSxTY
At that point, Bitcoin becomes an alarm bell for SHA256 because the nation state with that capability is going to first use that capability for strategic advantage through compromising hostile states’ secure comms first
