Green Supply Chain Management for Digital Assets in the Metaverse: Leveraging Blockchain and AIoT

The way digital assets are exchanged is rapidly evolving with the emergence of the Metaverse. In particular, immersive and decentralized platforms are reshaping transaction dynamics by offering new levels of interactivity. However, with these innovations come substantial challenges, especially those related to ensuring secure, energy-efficient, and interoperable asset flows across domains. Motivated by these needs, this article present a transaction framework that is designed to balance scalability and sustainability. Specifically, we combine the relay chain-parachain architecture with chameleon hash signatures (CHSs) to construct a mechanism capable of handling cross-domain digital content exchange. The proposed design aims to support flexible asset handling while keeping computation and energy demands in check. Taking inspiration from green supply chain management (GSCM), the framework also reflects concerns about sustainable digital asset governance. To evaluate its practicality, we carried out experiments across various network conditions and transaction volumes. The evaluation results suggest that our framework maintains low latency and reasonable energy efficiency, all while ensuring secure and interoperable transactions in the Metaverse context. These findings point to the potential of the framework as a stable infrastructure for digital asset management at scale in future decentralized environments.
