“This is the story of the revelation in late 2013 that Bitcoin was, in fact, the opposite of untraceable—that its blockchain would actually allow researchers, tech companies, and law enforcement to trace and identify users with even more transparency than the existing financial system.”
Maybe technically… But we’ve come up with some pretty ridiculous cryptography schemes that would take billions of years to crack.
You would be surprised in finding out that the majority of blockchains out there aren’t Quantum resistant, tho (elliptic curves being the reason mainly but I am not an expert)
