RT Journal Article T1 On the continuous contract verification using blockchain and real-time data A1 Martinez Rendon, Cristhian A1 Camarmas Alonso, Diego A1 Carretero Pérez, Jesús A1 González Compean, J.L. AB Supply chains play today a crucial role in the success of a company's logistics. 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 ¿ PB Springer SN 1386-7857 YR 2021 FD 2021-02-23 LK https://hdl.handle.net/10016/33834 UL https://hdl.handle.net/10016/33834 LA eng NO This work has been partially supported by the project “CABAHLA-CM: Convergencia Big data-Hpc: de los sensores a las Aplicaciones” S2018/TCS-4423 from Madrid Regional Government and by the Spanish Ministry of Science and Innovation Project “New Data Intensive Computing Methods for High-End and Edge Computing Platforms (DECIDE)”.
