Die Verkettung wird \u00fcber kryptografische Hash-Eintr\u00e4ge, eine Art Pr\u00fcfsumme, vorgenommen. Jeder Hash-Eintrag wird aus allen Datens\u00e4tzen eines Listeneintrags erstellt und sowohl im vorhergehenden als auch im nachfolgenden Listeneintrag vorgehalten. Die Listeneintr\u00e4ge werden somit unver\u00e4nderbar miteinander verschwei\u00dft, \u00e4hnlich einer Kette.<\/p>\n

Weiterhin handelt es sich bei Blockchain um eine vollst\u00e4ndig redundante Datenablage. S\u00e4mtliche Daten befinden sich bei allen Teilnehmern des Netzwerkes und werden st\u00e4ndig synchronisiert.<\/p>

Die tats\u00e4chliche Quintessenz ist aber die Programmierbarkeit des Netzwerkes \u00fcber Smart Contracts. Ein Smart Contract ist ein kleines Programm, das in die Blockchain eingespielt wird und in der Blockchain, wie andere Daten auch, redundant und unver\u00e4nderbar vorgehalten wird.<\/p>\n

Durch das Zusammenspiel von Smart Contracts, Daten und Events, also vorab definierten Ereignissen, lassen sich bestimmte Prozesse f\u00e4lschungssicher und vertrauensw\u00fcrdig abbilden, die bis dato nur \u00fcber Mittelsm\u00e4nner realisierbar waren.<\/p>\n
