Design and Implementation of XGBoost‐Based Cyberattack Detection and Blockchain‐Enabled Charging Station

Digital Twins and Applications, Volume 3, Issue 1, January/December 2026.
The charging station (CS) plays a crucial role in charging electric vehicles. Therefore, it is necessary to protect the CS from cyberattacks. This paper proposes an architecture for the security of the EV fleet during charging using the XGBoost model and Hyperledger Fabric to protect battery management systems (BMS) from cyberattacks.

ECKOchain: A FAIR blockchain‐based database for long‐term ecological data

Methods in Ecology and Evolution, Volume 16, Issue 6, Page 1020-1027, June 2025.
Abstract Open data practices in ecology are increasingly accepted, yet primary long‐term ecological data remain hard to find. Barriers preventing open long‐term ecological data include social and economic constructs such as a sense of data proprietorship and fear of misuse of complex datasets. To incentivise open primary ecological data and ensure long‐
