Can someone with solid encryption knowledge debunk/explain this?

@georgevaccaro @lukedashjr @nvk
bitcoin uses sha-265 not RSA
...but if RSA is cracked it's a big deal for internet security
from what I understand RSA uses fancy elliptical curves and prime numbers to cypher
sha-265 is just a big dirty "let's express the entire message as a single integer and scramble it using an algorithm" and it just sort of works
funnily enough the latter is more resistant to quantum computing
not my field of expertise by any stretch but I wouldn't sell all your bitcoin just yet.
@georgevaccaro @skells @lukedashjr @nvk I've started hunting down perhaps some more digestible discussion on the implications here that aren't totally unassailable god-tier mathematics. lol. It's my current (almost completely ignorant) understanding that this doesn't impact EC algos.
@ctrlbreak @skells @lukedashjr @nvk
Let's hope so. Who else can we tag here (so many less folks on mastodon)?
Maybe @excellion has some ideas?
@skells @lukedashjr @nvk
Well SHA-256 is used for mining but ECDSA is used for Bitcoin's signatures. I'm not saavy enough to know if 1. The claims about RSA are true and 2. If the same principles apply to ECDSA.
Looking for someone with more cryptography knowledge to help explain...
