The famous cryptographer Hal Finney, the second user of the virtual currency Bitcoin, lives in the same town as Dorian Nakamoto, the man Newsweek says is responsible for creating Bitcoin. Andy Greenberg of Forbes had a hunch that Finney might be the ghostwriter who polished Dorians non-native English prose. But when he went to meet Finney, diagnosed with amyotrophic lateral sclerosis, he became convinced otherwise. The result isnt the scoop Greenberg wanted, but its a fascinating portrait of an extremely accomplished man.
