Blockchain Reloaded

Authors: Sebastian Rohr and Markus SoppaRepresentative: Axel Pomper

Digitalisation has tremendous potential due to the networking of devices in the Internet of Things – especially in the industrial environment. Technologies such as IOTA’s third generation Blockchain help to realize this potential on a secure basis and to sustainably drive forward the digitization of German companies.

No change is as important for the working world as the digitization. However, the fourth industrial revolution will not only create new solutions for production but also completely new business models. While Internet of Things networking and communication connects millions of devices, laying the foundation for digital, efficient value creation, it also provides enough scope for potential hacker attacks. Therefore, in the digital world, the only person who succeeds in the digital world is to exploit all the benefits to the highest degree while keeping the negative effects and risks as low as possible. Last but not least, technologies that make communication in the internet of things necessary are required.

Blockchain 3.0

Die Blockchain ist sicherlich das bekannteste Beispiel für eine solche technologische Lösung. Von ihrer ursprünglichen Form ist sie jedoch mittlerweile weit entfernt. Als gewinnversprechende Variante für sichere IoT-Anwendungen gilt indes die Blockchain 3.0, bei der es sich im engeren Sinne gar nicht mehr um eine Blockchain handelt, sondern um einen sogenannten Directed Acyclic Graph (DAG), der die positiven Eigenschaften der Blockchain vereint. Dieser zielgerichtete zyklische Graph fußt auf einer dezentralen, verteilten Datenstruktur. Diese macht Transaktionen nicht nur transparent, sondern speichert sie auch unver-änderbar, chronologisch und quantencomputerresistent in einer Netz-werkstruktur. Das Besondere: Der DAG ist partitionstolerant, schnell und kommt im Gegensatz zur klassischen Blockchain oder anderen Distributed-Ledger-Technologien (DLT) komplett ohne Transaktions-gebühren aus. Außerdem lässt er sich quasi unbegrenzt skalieren. Damit bildet er die ideale Grundlage für anknüpfende Technologien im IoT, etwa automatisierte Bezahlvorgänge.
