This article explores the business benefits and technical challenges of blockchain technology implementation in the human resources (HR) domain, specifically in a recruitment space. Recruitment is one of the most critical parts of HR management, one in which there must be an establishment of trust at the beginning of interactions between parties. The authors posit that there is a need for a unified platform where certificates and academic degrees are safely kept in order to ensure the integrity of information and to have a means of verifying the validity of the qualifications, all while ensuring privacy. They propose the design and implementation of a platform exploiting two different open source platforms: Ethereum and Hyperledger Fabric. They then analyze each architecture’s basic features and compare those features to outline lessons learned.
