Uma abordagem baseada em blockchain para armazenamento e controle de acesso aos dados de certificados de alunos do ensino superior

Abstract

Blockchain is considered an emerging technology, having aroused the interest of researchers
\nand industries on the world stage. After the success of this technology in the financial market
\nwith virtual currencies (such as Bitcoin and Litecoin), blockchain starts to be used by different
\ndomains, such as government and education, as it provides a reliable, scalable and immutable
\ndistributed environment for the realization and storage of transactions on a network. Smart
\ncontracts are one of the features of the Ethereum blockchain, which has the ability to run a
\nprogramming model for applications distributed in untrusted environments. These contracts
\nreside on the blockchain and enable process automation in several stages. Smart contracts have
\nbecome one of the most sought-after technologies due to the high customization they add to
\ntransactions, allowing to seek blockchain-based solutions to problems in industry and academia.
\nHigher education is a system with several challenges that can be solved with the adoption of
\nthis technology. Protecting data transactions involving student degrees is one of the challenges
\nconsidered by educational institutions. Thus, this work presents an architecture proposal based
\non blockchain technology to store and consult data from diplomas issued by higher education
\ninstitutions. Through this architecture, a new approach for the validation of diploma data with
\nthis emerging technology was evaluated. As a proof of concept, a prototype of the environment
\nwas implemented using smart contracts based on the Ethereum platform. After implementation,
\nan evaluation was carried out with specialists in the management of diplomas and an analysis
\nof the performance of the transactions carried out in the prototype was carried out. In view of
\nthe results obtained, the proposal proved to be adequate to the process of storing and consulting
\ndiploma data.
