Blockchain Technology for Absence Tracking

The purpose of this paper is to present a Blockchain solution for tracking absences. In our approach, recorded absences are timestamped transactions stored in blocks that are linked together to form a chain, where each block contains a hash that identifies the previous block. As a case study, we have opted for secondary school. Our Solution will provide the ability for teachers to securely and unchangeably mark the absence of their students. Parents will be able to access their children’s absence history in real time, and administrative bodies will be able to manage student files seamlessly.
