Note on Illegal Content: Remember that Bitcoin is traceable, and Bitcoin never forgets. Please think twice before uploading illegal content even if just for fun. It can ruin your life forever.



Unlike the cloud based Internet where it's easy to get away with uploading illegal content, Blockchain remembers forever, and because the content will stay on the blockchain forever with your signature, you don't even have the deniability when you get caught.



It's a completely different paradigm, even if the trace technology of today is not powerful enough for cops to find you today, you can get caught 10 years in the future when it will have advanced, because the data stays on the blockchain forever, and there's nothing anyone can do to erase it.



And lastly, if you already did upload illegal content using this protocol, I'm sorry, I don't know what to say.
