Abstract

Web 3.0 is a term used to describe the next generation of the Internet being built on blockchain technology. It is expected to have a significant impact on society by decentralizing power and control over social media platforms, thereby providing diverse interaction. Meanwhile, Artificial Intel- ligence (AI) continues to advance, enabling intelligent systems across various domains. The convergence of these two transformative forces–Web 3.0 and AI–holds immense potential to revolutionize our world. Key topics include data sovereignty, blockchain governance, agentic AI, and its infrastructure.

The Journal of Web Engineering publishes selected papers from the International Conference on Real World Applications of Agentic AI for Web 3.0 (ICOW3) as a special issue. These papers cover specific themes, including Web 3.0 and AI, that align with the aims and scope of the Journal of Web Engineering.

ICOW3 aims to bring together researchers and practitioners from various disciplines in academia and industry to tackle emerging challenges in the engineering of Web 3.0 and AI. ICOW3 2025 took place in Seoul, Korea, on November 5–6, 2025. The conference was also offered to online participants. This special issue includes extended versions of the best papers presented at ICOW3 2025.
