This is reddit link about ethereum’s Akasha project.
Akasha project is decentralized SNS lives upon ethereum platform. Akasha will use IPFS as content storage system. (at least for now)
From this link, Akasha project lead developer mentioned about IPFS and FIlecoin
" when IPFS JS is completed, it would basically make IPFS accessible from normal browsers and I suppose Filecoin could become something quite big with all that penetration potential."
I think this is direct threat to maidsafe. isn’t it??
