It was a successful experiment: for the first time a “Blockchain MasterClass” was held during the “IT-Strategietage” in Hamburg. The responses was very good – due to high demand the space for the class had to be expanded twice. The participating IT managers came from an impressive spectrum of industries: automotive, finance, medical, media, real estate, trade and transport logistics were represented.

Frank Bolten started the MasterClass with a brief introduction that focused on the tension between “private” and “public” blockchains and the fascinating possibilities of token-based economies. Furthermore, Frank gave an overview of useful tools to support the evaluation of use cases, where blockchains might be helpful. The next presentation focused on the technical aspects of blockchains.

Volker Skwarek, Professor at the HAW Hamburg and a technical adviser to CHAINSTEP, gave an overview of how blockchains are technically defined. This was followed by an introduction to smart contracts. A key element was a list of criteria that help to decide under which circumstances smart contracts should be used. In the following explanation Volker Skwarek concentrated on Industry 4.0 applications. This was followed by a live demonstration that illustrated how a smart contract works on the blockchain. The exchange after the presentation highlighted the current importance of this topic.

The third part of the MasterClass was taught by Sebastian Beyer, product manager at CERTIVATION. It is the latest spin-off of the ROSEN Group. With help from CHAINSTEP they launched their new service “BEC” (blockchain ensured certificates) just in time to present it at the Blockchain MasterClass – it was a world premiere. Please find more information on the BEC service in a separate blog post on this site (here).
