Trägt man in diesen Tagen über Bitcoin, Blockchain und Kryptowährungen vor, steht man vor der Frage: Diskutiert man die Technologie oder präsentiert man direkt die gesellschaftlichen und ökonomischen Implikationen? Seinen Zuhörern in wenigen Minuten einen Zugang zu einer komplexen Technologie zu vermitteln, ist riskant. Schnell verliert man sich in Alices Kaninchenbau aus den Augen. Doch die Zuhörer können ebenso ratlos zurückbleiben, wenn man direkt die potenziell revolutionären Implikationen anspricht. Aufgrund dieses Dilemmas und der Komplexität von Kryptosystemen wollen wir Ihnen hier die Technologie anhand von Metaphern näherbringen. Wir hoffen, dass Sie uns so auf die Reise ins Blockchain-Universum folgen.
