Abstract
The adoption of Distributed Ledger Technology (DLT) has been growing tremendously in recent years following the introduction of Bitcoin in 2009. However, the usefulness of DLT is not limited to the financial sector, and this paper investigates the viability of DLT architectures for use in Higher Education (HE). This sector faces challenging financial constraints, and one way to address this problem is to adopt emerging DLT technologies as architectures for HE systems. This article presents the ASTER Open Source system, a hybrid DLT integration within the context of a student submission system for assignment grading purposes. ASTER addresses many concerns of traditional system architectures such as centralisation, system downtime, and decoupling; all of which are mitigated through the use of blockchain technology. The advantages and drawbacks of such a new approach are discussed, including the aspect of security concerns relating to student work being submitted to a public ledger.
