A Multi-Light-Node Blockchain Architecture

Any existing modern business already operates a great number of different IT systems. If businesses want to leverage the trust and other security benefits of blockchain in their business model, many, potentially all of these systems may have to be integrated. We suggest an architecture of multiple blockchains with a limited number of full nodes and many light clients that aims to keep costs low and the security level high. Our architecture shows how multiple distinct businesses can cooperate through blockchain technology, for example in logistics processes. This paper should serve as a starting point for managers, system architects and implementors who want to lay out their own architecture for their specific business requirements.
