MPC‐Facilitated Adaptive Security Framework for BFT Protocols

IET Information Security, Volume 2026, Issue 1, 2026.
The growing use of blockchain and distributed systems requires Byzantine fault tolerant (BFT) protocols that remain secure under dynamic adversaries. However, existing BFT protocols often rely on static assumptions and lack clear mechanisms to detect and remove malicious or denial‐of‐service (DoS) nodes during execution.

An AI–Blockchain‐Based Network Optimization Framework for Energy‐Efficient Computing Systems

IET Networks, Volume 15, Issue 1, January/December 2026.
This paper presents AIBLOCK, an AI–blockchain‐based network optimisation framework that enables energy‐efficient and self‐optimising operation in large‐scale distributed computing networks. By integrating multi‐agent reinforcement learning with real‐time blockchain telemetry, the framework adaptively adjusts consensus parameters such as the block size,

A Private Blockchain and IPFS‐Based Secure and Decentralized Framework for People Surveillance via Deep Learning Techniques

IET Software, Volume 2026, Issue 1, 2026.
The modern metropolis essentially demands the use of state‐of‐the‐art, real‐time surveillance systems, which should be reliable, scalable, and respectful of privacy at the same time. Critical shortcomings in traditional architectures are single points of failure, poor scalability, frequent data breaches, and inadequately managed privacy.

Empirically comparing the performance of blockchain's consensus algorithms

IET Blockchain, 2021
Blockchain‐based audit systems suffer from low scalability and high message complexity. The root cause of these shortcomings is the use of “Practical Byzantine Fault Tolerance” (PBFT) consensus protocol in those systems.

Rethinking Blockchain and Power Dynamics in Supply Chains: A Critical Discourse Analysis

Journal of Business Logistics, Volume 47, Issue 1, January 2026.
ABSTRACT Despite a generally positive discourse on blockchain technology in academic literature, firms have struggled to implement it in their supply chains. In this article, we are deconstructing the typically positive perception of blockchain in the literature through a provocative style of theorizing and critical discourse analysis.

Privacy‐Aware Federated Recommender Systems for IoT Healthcare: A Review of Computational Methods, Multimodality, and Optimization for Real‐Time Personalization

Applied Computational Intelligence and Soft Computing, Volume 2026, Issue 1, 2026.
The rapid increase in the number of internet of things (IoT) devices in the healthcare sector has produced an ecosystem of multimodal data that includes physiological signals, behavioral measurements, and electronic health records. Nevertheless, centralized analytics are dangerous to the privacy and safety of patient data.
