Here is a really interesting example of a tool that has been built on top of the bitcoin "rails". Monegraph allows digital artists to fix the age old problem of being ripped off (copy and paste).. This would have been extremely useful at Serverside for our image verification business.
Here’s how Monegraph works. Artists can visit the Monegraph site and sign in with Twitter. Then They submit the URL of a digital image they’ve created. In return they receive a blockchain key and value they can store in a NameCoin wallet, similar to how they would store bitcoin. This is their digital deed, a unique claim of ownership to the piece of art. If someone else submits the same image, Monegraph detects that it’s already been claimed. Monegraph also tweets out an announcement of the ownership to commit it to public record. Once a creator watermarks an instance of a digital art piece as the original, they can then share copies however they want. The piece can be redistributed or remixed, and the artist can watch as it takes its own viral course knowing they haven’t lost control. If they wish to sell the piece and the rights to it, they can sign the Monegraph deed over to a buyer.
