There is a great development that can solve a lot of problems and can open the door to new features, I am trying to figure out if there is a way to build this feature.
The idea is to build an "hash" to identify a real person. There must be 3 property.
...
What development, what problems and what benefits are you talking about?
I don't like the concept because it makes everyone traceable. And then everything else about a person be traceable. Financial transactions, events participation, traffic tickets, ...
You can make an argument for the unknown benefits of this concept, but the potential harm could be tremendous if the system allows its database (blocks) to be linked with other databases (many altcoins describe different features). I'm sure there will be hacks/governments/merchants who want to take advantage of such information.
