Well you can title/name addresses on blockchain.info. Whilst bitcoin was designed to be as vod described above I think being able to name addresses for things like this would have its benefits for those who wanted to use this feature.
Thank you for all the answers. This is very helpful.
What do you guy's think of a feature/service where you can verify a name of a bitcoin address? Not in the root of the Bitcoin chain. More like some additional service for those who like it. The scope can be for businesses transferring money to each other, wanting some extra safety. Bitcoin wallets specialized in B2B transactions can integrate this API, so their customers can have some extra safety.
Our company contains a well known international trustfully brand that offers loads of data for many years now. I'm thinking about the possibility to use this brand to set up an API service to check names with known bitcoin addresses.
I'm wandering what you guy's think of such a service.Please watch this video carefully:
http://www.youtube.com/watch?v=xUNGFZDO8mM Understand anything outside of the blockchain is NOT secure. There are multisig options out there that do not have your identity but can do what you are talking about.
NOTE: if you are asking such basic questions, you do not need to be involved around someone else's bitcoins or involved with their transactions, much less trying to invent a service for the masses. Please learn a little about what the system is and how it actually works.
