It's my goal before the December to go through some of the code side of the blockchain. So I was in search of good tutorial courses which are both theory and some hands-on. I found freecodecamp as a good resource to start with. I am going through their content few minutes per day. Hopefully by the end of Dec 2021, I have enough knowledge in smart contracts and chains to work with :) You can check out the freecodecamp course: https://www.youtube.com/watch?v=M576WGiDBdQ
