I'm not sure if this exists yet, but if it does, it would totally decentralize the internet. Being blockchain powered, its content would become immutable, making it difficult for any government or nefarious organization, to take control over it and shutdown the websites living under such system.
I've heard about Maidsafe, but recently found out that it was not blockchain powered. Still, it has interesting technology that might become useful once released.
What do you think?

You mean having also a decentralized internet access? If so, things will be abuse in the future that is for sure, because of unlimited access of everything. What will be its feature? Things will be hard I guess.
