Meta-Learning: A Digital Learning Management Framework Using Blockchain for Metaverses

The worldwide education landscape has transformed due to the COVID-19 pandemic, providing an opportunity to enhance virtual learning. Nevertheless, this transition has disadvantages, including less face-to-face interaction and the possibility of student seclusion. The metaverse, a digital realm, provides an optimal substitute for conventional virtual education. Nevertheless, its immersive nature poses issues for conventional digital learning management systems. This article proposes using blockchain technology and non-fungible tokens (NFTs) as unique identifiers to handle credentials and transactions in the metaverse while ensuring security effectively. This approach tackles difficulties associated with the administration of certificates, including issuing, maintaining records, ensuring traceability, and preserving integrity. Additionally, it establishes a fairly secure setting that effectively prevents data manipulation. The proposed approach entails the implementation of a smart contract that integrates a credential’s transactions and an attribute-based access control mechanism. The research further addresses the challenge of limited storage resources caused by the dynamic nature of the metaverse and the requirement to manage huge quantities of data. The implementation results and applicability assessment confirm the feasibility of the proposed approach. Eventually, this study contributes to the ongoing discussion on the convergence of blockchain, NFTs, and smart contracts with its new perspective on digital learning management in the metaverse platform.
