Ever wonder how Cordano works? There is a lot under the hood with this one and I thought this is a great break down. I found it helpful and hopefully you will too!

A lot of the earlier videos have focused on machine learning but lately he has been explaining all types of blockchain and cryptocurrencies. Check out his channel!
