"Satoshi knew." a16z crypto research partner @ittaia on how Bitcoin solved a 40-year-old academic problem, and how its creator knew it all along: "It actually took quite a few years for people to realize that this is kind of solving a Byzantine agreement problem… a very core academic problem that has been studied for 40 years." "In that sense Bitcoin is kind of this huge revolution in how to solve Byzantine agreement. In fact, if you look at early emails from Satoshi Nakamoto, he said the core technical aspect of Bitcoin is solving Byzantine agreement."(a16z crypto)
