Requirements Engineering for Web3 Systems: Preface

The 1st International Workshop on Requirement Engineering for Web3 Systems (RE4Web3), held at the 32nd IEEE RE Conference 2024, fills in the space between traditional Requirements Engineering (RE) and particular challenges posed by Web3 technologies. The workshop discussed changing RE artifacts, processes, and practices to efficiently build and operate emerging Web3 systems. The accepted papers showcase the diversity and depth of research in this emerging field, addressing key topics such as smart contract compatibility with Central Bank Digital Currencies, RE challenges in rollup construction, privacy and security in blockchain-based federated learning, and infrastructure requirements for blockchain-native information systems. The new findings described in these industry-focused papers add to the formation of the discipline and lay the cornerstone for future research and practice in RE integration with Web3 technologies.
