Scale By The Bay 2020: Rudolf Bayer, C-chain: the Integration of 5G and real time Blockchain

ai.bythebay.io Nov 2025, Oakland, full-stack AI conference Many IoT applications require communication and recording of events, both in real time. The recording of events must be immutable and legally binding, which calls for blockchain technology. 5G offers real time, but classical blockchain techniques are far from real time. C-chain is a lean and high performance variant of blockchains and achieves real time in booking machine transactions in a blockchain datastructure and DLTs. Therefore, 5G and C-chain are a perfect match for new IoT applications. This talk gives an overview of the basic principles of the C-chain technology and presents several application scenarios from the fields of driver assistance and autonomous vehicles. The C-chain technology was developed at TUM and has recently been transferred to the new startup catena GmbH. Rudolf Bayer TU Munich Professor Rudolf Bayer is professor emeritus of Informatics at the Technical University of Munich where he had been employed since 1972. He is noted for inventing three data sorting structures: the B-tree (with Edward M. McCreight), the UB-tree (with Volker Markl) and the red-black tree. Bayer is a recipient of 2001 ACM SIGMOD Edgar F. Codd Innovations Award. In 2005 he was elected as a fellow of the Gesellschaft für Informatik.
