Suppose one wanted to build a Bubble app with an internal unit of account that enables users to transact with one another. Facebook Credits is a pretty good example. Is there any reason to use some sort of private blockchain, other than being able to say you use a blockchain? It seems Bubble is capable of handling such a task, since a credit system is simply based on database entries.
Would it be foolish to attempt to build a virtual currency within a Bubble app, using the Bubble DB? What kind of security risks would that pose?
