The problem is you need to store that data. Blockchain or websocket json calls are not going to fix that. You can't store data on the internet because the internet is like a highway of sending and receiving data from another computer. That's why I said it's a spectrum. Eth claims to be decentralized but it's arguably definitely not. How is it decentralized if someone can change the consensus mechanism without consensus of miners and selling your protocol as a ICO.
