the blockchain

The thing we must remember is there is no "the blockchain", there are many. The steem blockchain and many others are very open, though some are not. They don't have to be open at all to still be blockchain based, so we need to be careful what we ask for as blockchain is a tool. As with any tool it is possible for them to be used for malevolent or benevolent purposes and we simply need to focus on steering this towards use of a blockchain that is OPEN (like steem, or EOS, etc)
