Tidecoin is a small step for mankind and a huge embarrassment for everyone involved in dealing with it. Quantum resistance is a fiction imparted to u through internet propaganda. Nothing major in being quantum resistant when there exist no real computers to test the encryption a thing uses to claim the touted resistance. When first computers go mainstream then Im afraid that would be a dreadful end for everything humankind has built thus far including bogus technologies alleged to be the next big thing.
wait so you think there's no use for it because there is no publicly known computer capable of doing it yet. but do you not think that the technology is fast approaching that level?
in regards to your point regarding the encryption it does use they are using one of the algorithms selected by the NIST for post quantum security - which while I guess you can't actually test you can determine if it can hold up to x number of qubits?
and finally yes, EVERYTHING digital is eventually going to need to be upgraded to be secured against this thread -- one year? ten years? 25 years? idk - but it will happen or are you saying that day won't ever come?
