Filecoin actually addresses the technical challenges in building something like this, and maybe Storj will end up using it in their stack.
Soon will have simpler explanation. :)
In this case and in storjcoin case the actors behind it all remain anonymous
FWIW, we aren't really anonymous. Neither in the storj case (you can find who they are in their website), nor in the Filecoin case. (hi!)
If this filecoin does take off and does what is being promised I will personally add hundreds of terrabytes of storage from our storage servers.
But seeing what Storj are doing I am extremely sceptical so please understand where I am coming from.
And, by the way, see http://static.benet.ai/t/ipfs.pdf -- https://github.com/jbenet/ipfs -- Filecoin's sister protocol.
In any case, congrats on the launch. I've only skimmed the white paper so far, but the filecoin.io concept looks promising.
