Exploring Blockchain in the Metaverse: Review of State-of-the-Art Frameworks and Future Research Challenges

The integration of blockchain technology within the metaverse is driving a paradigm shift in how digital interactions and ecosystems are built and maintained. This paper investigates the transformative role of blockchain in enhancing trust, transparency, and decentralization across virtual environments. By enabling secure ownership of digital assets, identity verification, and decentralized governance, blockchain strengthens the infrastructure of the metaverse. The study also examines practical implementations across sectors like virtual commerce, remote healthcare, and immersive education. Finally, it discusses existing limitations such as latency, standardization gaps, and resource constraints, while outlining potential paths for future research and development.
