If selfkey can really handle transactions without KYC then I am sure it will be a successful project. Currently, there are many people wishing to transact without KYC.
they are afraid of providing KYC and their personal information and are afraid of being sold to terrorists. That is why the demand is very large.
I think there is no centralized system that does not require KYC, selfkey also requires kyc, but the process may be faster, I think many centralized systems want to use a system without KYC in each of their entities, but we also have to understand, KYC is also important for building projects, apart from the KYC abuse problem.
