Emissão e validação de diplomas digitais usando a tecnologia blockchain

Abstract

In Brazil, the production of fake diplomas is a significant issue. Despite having stringent laws in place, they prove insufficient in regulating this illicit market. Individuals who use counterfeit diplomas without having the necessary qualifications are detrimental to the job market and the credibility of educational institutions. They exploit a loophole in the inefficient certification process for graduates of higher education courses. With the rise of digital advancements, there are various options to consider as alternatives to paper diplomas. One such solution is blockchain technology, which has gained popularity recently due to its security and transparency. It has been effectively utilized in services such as property registration, credentials, and documents. Therefore, this work aims to develop a system capable of registering and authenticating higher education diplomas using blockchain technology. There is a comparison of cost and execution time for the same storage and file access operation between the Ethereum blockchain and the Solana blockchain, which has lower usage costs and better execution time performance.
