Nobody knows who invented Bitcoin . But you can visit the man who did important preparatory work for the cryptocurrency. He lives on a construction site in a new development area in Braunschweig and offers his visitors snacks. “Go for it,” he says and sits down on a garden chair in the middle of a half-finished room that will one day become his study.
The computer scientist Stefan Konst was the first to describe a general theory of a blockchain . The technology on which cryptocurrencies like Bitcoin are based. About 23 years ago, on August 9, 2000, Konst submitted his thesis to the Technical University of Braunschweig, in which he dealt with “cryptographically chained entries”. Bitcoin has only been around since 2008.
