We should start building some prototypes leveraging the 2nd layer of the blockchain and then we should also promote that by using some DAO funds to attract app developers to build on hive. There can be many use cases of that - we can build a few to just show how it works.
And we can use some other authentication mechanism to just make sure real people use that, like some bio-metric based OTP such as Aadhar for India.
I think, at this moment, we should really spend a good amount of the DAO fund to promote.
