I would like to see people writing e-books and leaving behind a bitcoin address on the last page. The writer would try to let it go viral, it would be like passing trough a hat. If the book was really good it would get higher views and a higher donation likelihood.
The trouble with this is that people would make copies and put their own address in it. I know how that goes, it would only be a matter of time.
My question is, can the blockchain be used to verify that it is you who wrote the book?
