Ask HN: What decentralised web projects have the most potential?

I'm very interested in this idea of decentralising the web, but there seems to be so many separate projects to do this - IPFS [1], Dat [2] and Solid [3] to name a few. Which of the existing projects (if any) to do you think has the potential to gain mainsteam usage?
