I see people working as "Escrow" in the forum. These people work like a kind of brokerage house in their bitcoin payments. And they get commission from the transactions made. I know that reliability is very important for this.
But who gives the title "Escrow"? Is there anyone authorized for this job?
You yourself will be the one t entitle yourself as an escrow but it is upto the community in here if they will use your service. Like what they have already mentioned, before you can start you first must have to prove that you are a trustworthy person and that you are transparent enough to know that you will not do shady stuffs when it comes to handling other peoples money and items.
