Did the Byzantine Generals Problem really exist in the historical record, or is it just a thought experiment for fault tolerance? Is the Bitcoin network a middleman in the BGP? Is mining like a brute force attack?

These questions are from the second and third sessions of MOOC 12, which took place on September 19th and September 27th 2019, respectively. If you want early-access to talks and a chance to participate in the monthly live Q&As with Andreas, become a patron:
