Why Web3?
&gt; financial applications have been built on top of Ethereum that all share the same database and users can move from application to application, keeping their data (and their login credentials stored in their wallet) as they go.<p>Does anyone have examples of this in the wild? I often hear data portability listed as one of the great benefits, but I don’t have a grasp on what that actually means.<p>In my mind, the data needs to be structured to be useful, otherwise other DAPs wouldn’t be able to act on it. Who defines the structure? And who manages changes?
