About the Book

Studienarbeit aus dem Jahr 2018 im Fachbereich Informatik - Wirtschaftsinformatik, Note: 1,0, Hochschule München, Sprache: Deutsch, Abstract: Diese Arbeit gibt einen Überblick über die Funktionsweise der Blockchain-Technologie. Am Beispiel von WhatsApp und Bitcoin werden Chancen und Risiken aufgezeigt. Die Blockchain-Technologie ist generell eine neue Technologie, deshalb hat sich bisher noch keine einheitliche Definition durchgesetzt. Der Blockchain ist ein sogenanntes "distributed Ledger" - eine Datenbank, welche (finanzielle) Transaktionen beinhaltet und dezentral über alle Computer läuft, welche die jeweilige Blockchain Software installiert haben. Alle Transaktionen, welche gemacht wurden, werden von einem teilnehmenden Knoten (z.B. Computer) im Netzwerk der Blockchain Software durchgeführt und werden wegen Datenintegrität anschließend an alle anderen Knoten weitergegeben. Bei bestimmten Intervallen, z.B. ungefähr zehn Minuten im Fall von Bitcoin, wird eine Teilmenge von allen schwebenden Transaktionen zusammengefasst und in einem neuen Block linear und chronologisch umgewandelt. Im Falle, dass nicht alle Transaktionen in einem neuen Block passen, bevorzugen Miner Transaktionen mit einem höheren Transaktionswert. Der neue Block beinhaltet die Referenz des Bezeichners von dem letzten hinzugefügten Block und seines eigenen, damit der nächste Block sich auf dem vorherigen beziehen kann.
