I posted this idea elsewhere, I think this is the right place.
The idea is very straightforward. It should be possible to crate an adress which you sign with a cerificate, muh like microsoft signs its own programs like excel and windows components. Signing should create a few bytes of data that I guess could be treated like an ntf that is associated with a particular address.
This is good if you want to buy something expensive and you worry if the address used is really the one you want to use.
The idea requires a few simple additions to the wallets.
The first is of course is the ability to create such an address.
Then you also need code that shows the owner if you paste the address of, say, your car dealer.
I think this would add substantial value to cardano. It should be easy to implement. Much like when you a clearinghouse when you pay a bill, it will tell you who the receiver is. I think many people are spooked when they realise that crypto transfer is quite different from how banks work.
