A practical guide to requirement modeling and assurance for blockchain applications

System engineering tasks are playing an increasingly important role in the planning and implementation of blockchain-based applications. Solutions must now increasingly meet requirements beyond the integrity provided by the blockchain platform – such as performance, reliability, maintainability, privacy, and data confidentiality. In addition, in an increasing number of cases, it is necessary to perform actual architecture planning – with cross-chain and off-chain integration, external data sources, and “Layer 2” solutions.

The “Blockchain Systems Engineering for SMEs” course aims to give a focused overview of the main challenges and the current state-of-the-art solutions, enabling system-engineering-oriented design and further in-depth exploration of the introduced techniques as needed, showcasing practical approaches and patterns.

The course equally covers both inter-organizational platforms (like Hyperledger Fabric and consortium Ethereum) and public (Ethereum-based) networks, adjusting the content to fit the participants’ needs based on a preliminary assessment of their requirements via survey.

Due to its nature, the course is primarily recommended for IT professionals with a basic understanding of blockchain but is also open to engineers just getting acquainted with this technology and also accessible to a broader audience with an IT background.

Dr. Imre Kocsis is an Associate Professor at the Department of Artificial Intelligence and Systems Engineering of the Budapest University of Technology and Economics (BME). His key research areas are the systems engineering and end-to-end resilience assurance of blockchain-based applications.
He is leading the participation of BME in the Hyperledger Foundation and leads the Education Workgroup of the Hungarian Blockchain Coalition.
