I love this article. As a freelance developer, sometimes I feel lack of my knowledge. This article gave me the big picture of Blockchain Application and Smart Contract Development. Actually, I was a Unity3D Game Developer. So, I sometimes want to go back to Unity and Games and something like that. But I know I should know about the Blockchain and should join and become a part of the great evolution though it is not so easy for me. I wish I had a list of all concepts that I have to know as a Ethereum Smart Contract Developer. That would be great help to me.
