Bitcoin Q&A: The ‘Byzantine Generals Problem’ thought experiment


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.
