Abstract

Verifying the legitimacy of academic accomplishments like CVs and diplomas has become increasingly difficult as the number of institutions participating in the global education market continues to expand. This has resulted in a heightened risk of academic fraud. The distributed ledger technology known as blockchain has the potential to be an instrumental factor in the resolution of this issue. The purpose of this study is to present a blockchain-based achievement record system that generates a record of accomplishments that can be verified. The purpose of the proposed system is to make the process of authenticating and validating certificates more trustworthy, straightforward, and expedient by capitalising on the one-of-a-kind capabilities provided by Blockchain technology (the public Ethereum Blockchain), as well as smart contracts. Here, we will discuss the planning and execution of the system, as well as its components and tools. After that, we conduct a number of studies to evaluate the system in order to measure its usability, effectiveness, performance, and cost. An evaluation using the System Usability Scale (SUS) produced a score of 77.1. We demonstrate through a review of the relevant literature that this system is a significant improvement over legacy systems, both in terms of its friendliness to users and its level of efficiency. In addition to this, we carry out an in-depth cost analysis and have a conversation about the benefits and drawbacks of various alternative blockchain solutions.
