There needs to be decentralized ID using an open protocol with any vendor able to join. The quality of those vendors will be based upon which firms trust them. I do think blockchain makes sense here, because the trust layer is decentralized and the native cryptographic signing primitives means it can’t be spoofed nor manipulated in a proprietary database locked from the public.

No idea if world coin is a workable solution, but I would like to be able to conduct KYC a single time and then selectively reveal my information to necessary parties, ideally only as a confirmation rather than data transfer. Why I have to constantly scan my ID for various vendors is absurd.
