So im reading up on nexus and ecc, and wondering how nxs can make the claim they are quantum resistant, when ecc will be highly susceptible to quantum attacks, and thereve already been proven security limitations to ecc such as side channel attacks and twist security attacks. Can someone please tell me nxs has implemented something different than ecc which proves its far more advanced than theyre "claiming"?
That's correct. ECC is a weakness. Colin discusses this a bit:

Ill watch it, but why do they claim quantum resistant if not?
The Nexus protocol is quantum resistant provided the end-user uses good traditional Bitcoin security practices. It can be made nearly quantum proof by combining ECC with other public key private key crypto algorithms through concatenation, and using new addresses for each transaction as a part of the protocol. Additionally, if there are better algorithms than ECC developed, proposed, and accepted by the mathematics and crypto communities, they will be adopted. Ultimately, this is a pressing matter not just for Bitcoin and Nexus, but for all crypto...
