In the last years, multiple investigations focus on incorporating new technologies to the supply chains, being Internet of Things (IoT) and blockchain two of the most recent and popular technologies applied. However, their usage has currently considerable challenges, such as transactions performance, scalability, and near real-time contract verification. In this paper we propose a model for continuous verification of contracts in supply chains using the benefits of blockchain technology and real-time data acquisition from IoT devices for early decision-making. We propose two platform independent optimization techniques (atomic transactions and grouped validation) that enhances data transactions protocol and the data storage procedure and a method for continuous verification of contracts, which allows to take corrective actions to reduce ¿eng© 2021, The Author(s), under exclusive licence to Springer Science Business Media, LLC part of Springer Natureiot applicationsblockchain technologymonitoring datacloud computingresearch articleInformáticahttps://doi.org/10.1007/s10586-021-03252-0open access123Cluster Computing-The Journal of Networks Software Tools and ApplicationsAR/0000028239
