Abstract

This paper presents a permissioned blockchain-based architecture that advances both the scientific understanding and practical implementation of distributed healthcare solutions in Web 3.0 contexts. Unlike approaches that address technologies such as blockchain, AI, edge computing, and immersive environments in isolation, this study integrates them to tackle challenges in transfer of care (also known as transitional care) scenarios. It proposes a hybrid onchain/off-chain architecture that ensures traceability, governance, and security across institutions. The solution incorporates digital twins, AR/VR interfaces, and 5G/Wi-Fi 6E connectivity to support real-time clinical decision-making and enrich interactions between patients and healthcare professionals. The Proof of Concept (PoC) demonstrates how a permissioned blockchain can optimize auditing, reduce reliance on intermediaries, and enable decentralized data management. The analysis indicates that the proposed architecture contributes to building safer and more transparent healthcare systems.
