This is a good idea. Anything to help these brave people would be very appreciated. The good thing with crowdfunding it on a cryptonetwork is that it would not have to go through the banking system, initially. Hopefully there is some level of anonymity to prevent donors being targeted as well.
My idea was to get a case like this:
Person A asks for information on a subject. He specifies what this ''information'' is. It could be a document, or a public statement, or a witness statement in the court of law of a certain country.
Person A also specifies how much assets he wants to put as the target amount. This is the amount of money / backing that is estimated to be required for the leaker of information to be safe from attacks against his or her income or physical safety.
Would also be nice if there's a mechanism to pay for leaks that have already been released without anyone asking for a request. For example, if I know I might be in danger, I might want to immediately release the information, provided I'd have a platform to publicize it and deter assassination attempts.
Ideally, it would be as easy as uploading a video on Youtube. Would this have a format like that? Like, every leak released can be accessed by anyone in the public?
