What is DX Document Exchange?

Could you elaborate on what DX Document Exchange is and how it functions in the realm of cryptocurrency and finance? DX Document Exchange seems to be a novel concept, so I'm curious to understand its purpose, how it differs from traditional document exchanges, and what potential advantages it offers in terms of security, efficiency, or otherwise in the financial and crypto landscape. Specifically, I'd like to know if it enables secure, encrypted document transfers, if it utilizes blockchain technology for verification or storage, and how it could potentially benefit financial institutions or crypto enthusiasts.
