Self-adaptation made easy with Blockchains

de Lemos, Rogerio, Sedgewick, Peter (2018) Self-adaptation made easy with Blockchains. In: Proceedings of 13th International Symposium on Software Engineering for Adaptive and Self-Managing Systems. . ACM ISBN 978-1-4503-5715-9. (doi:10.1145/3194133.3194150)


This position paper describes how blockchains facilitate the implementation of distributed self-adaptive systems. We demonstrate how the master/slave decentralised control pattern for self-adaptive systems, integrated with a permissioned blockchain, can protect nodes of a network against attacks by continuously adapting the membership of an access control list. Whenever malicious behaviour is detected, consensus on an updated access control list is reached, and that node is removed from the network. Using a smart home, as an example, we demonstrate that a permissioned blockchain is able to maintain a consistent view of a network of Internet of Things (IoT) devices in the presence of malicious nodes.
