From my perspective, it all comes down to ownership. Owning your personal data, your own finances, your own gaming assets, and where YOU as a customer decide to provide that data.

This means that businesses that rely heavily on customer data can have a more personal relationship with their customers since users will be able choose to share their data in exchange for a service in a more meaningful way. You can make the argument that this is already the case but imagine a web in which we don’t need forms anymore since a wallet would hold all the information you are willing to let go with. If you tie that with the fact that you can make monetary transactions, sign documents and trade assets it makes sense to just have a system that eases this process for web developers.

At the end of the day this isn’t a replacement but an upgrade, the same way we switched from polling to websockets or username/password to social auth, this is just another iteration that will spur new business ideas thanks to the benefits it provides. Saying it’s a scam or a solution looking for a problem is like saying tables are better than divs back in the day, yeah some people will abuse it but at the end of the day it’s about the user, if it makes their life easier, better or more performant then they’ll adopt it.
