Thanks a lot for the link, I'll look into it. A peer-to-peer publishing platform backed by blockchain is possible, but using torrents for storage and hashes stored in a blockchain OP_RETURN opcode. It's already done in a project I'm closely following, Slimcoin, the latest client allows for serverless "publications'.

But the real challenge is to rewrite even the low level protocols of blockchain and torrent servers and clients.
