I was listening to Joe Rogan's interview with Michio Kaku last week, and he commented that quantum computing will be the end of privacy. This of course got me thinking again about bitcoin in a post quantum computing world. So I started looking at the different ways that bitcoin could defend against this future threat. I know some SN members will think that this subject has been discussed too many times, but my fear has kicked up again.
To the future David Chaums out there, what do you see as the future? I know the current algorithms are going to be vulnerable at some point. I read about Lamport signature, Ring-LWE signature, the McEliece cryptosystem, the multivariate polynomial signature scheme, and XMSS signature. Are these viable solutions? Is it too early to worry about this? Should a new set of algorithms be tried now?
Cryptography is way over my head, but I'm sure there are SN users who understand these things.
I wonder whether there is a group of people out there who are actively addressing this issue?
