Wait a seconds, we can actually do that already but the only problem is we cant know from whom the transactions is being made and to whom it is being made. I mean crypto currency is already very much open source and whenever a transaction is broadcasted over the blockchain then it is embedded in the blocks and stays there forever and you can always see it through the block explorer. I dont think you need any additional features to be added to see it.

As I mentioned its the only name of the person which cant be disclosed as one can have thousands of addresses and wallets and thus no name attached to it really.
