Blockchain in E-Learning Platform to Enhance Trustworthy and Sharing of Micro-credentials

Blockchain is a disruptive technology and interest in its adoption is growing across many market sectors in Industry 4.0. However, the blockchain adoption is limited by the difficulty in managing private keys and wallets to interact therein. This paper describes the integration of a consortium blockchain within e-learning platforms. The adoption of blockchain in the e-learning platform maximises the reliability, verifiability and sharing of micro-credentials. The proposed solution aims at eliminating the difficulties of managing keys and wallets. The enhancement in the reliability of micro-credentials is particularly important in learning environments and in companies that want a guarantee of effective training of employees. The present article, in line with the European privacy framework, exploits the potential of blockchain without compromising user data protection.
