Going through your WP and the myriad of innovative product, I'm left wondering if there's a possibility of the platform developing its own blockchain down the line?
as you can read on whitepaper they are using ETH blockchain but they are opened to further update.

or if they will consider implementing their own blockchain, they will do.
But right now i think they are doing the better choice: implement over the most used blockchain
