Probably the team wants to insure users from mortgage crises, which were very painful in the past and I think it can turn out to be a very necessary platform.
Mortgages are debt instruments by assigning mortgages to property and borrowers to lenders as security against their obligations; in this case the borrower may still use or utilize the property; the mortgage rights of the property after the obligation to be paid. This platform is of course very real and needs a better innovative breakthrough.
This explains very well how viva platform will work, but I have some more concerns about the features of this project. Hoping that more video presentations will explain how the project really works.
Yes your idea is very good, of course because through pictures or video people will be more interested to see it, and some people will be easier to understand when equipped with illustrations of images or video. But with my writing alone the race has given a pretty good explanation.
