Blockchain‐Audited Federated Learning: Securing Data and Model Updates With On‐Chain Provenance

IET Software, Volume 2025, Issue 1, 2025.
We present a permissioned blockchain–audited federated learning (FL) framework that strengthens data provenance and model‐update integrity. Our contribution is primarily engineering and architectural: a modular two‐channel design (provenance vs. update‐audit), lightweight on‐chain validation with off‐chain analytics, and a practical mapping to the 1 ...

Scalable Consensus Algorithm and Storage in Decentralized Blockchain (SCSB) For Heterogeneous Internet of Things (IoT) Systems

The Journal of Engineering, Volume 2025, Issue 1, January/December 2025.
The SCSB design consists of the DO, DU, TA, and cloud server. The cloud server manages a huge number of data, hence it receives multiple DU requests. The DO is also authenticated and then allowed to upload data. ABSTRACT The internet of things (IoT) is widespread in various real‐time applications in developing smart environments.
