One that I was instantly drawn to was with Roger Wattenhofer, who’s a professor at the Swiss Federal Institute of Technology (ETH).
I wanted someone who knows what’s up to whiteboard, or blackboard in this case, how the blockchain works. Wish granted!
His two main ingredients are “asymmetric crypto” and “distributed systems.” If you understand these two things, then you can understand the technical details of the blockchain.
Bonus: He confidently explains that cryptography and distributed systems were created in the 1970s, which is somehow amusing and makes the whole thing much more approachable.
