The paper realizes an evaluation of Blockchain-based reputation systems used in education and research, starting from the definition of reputation in different contexts, then justifying the advantages of using the Blockchain technology for implementing reputation systems. A number of criteria are proposed for analyzing Blockchain-based reputation systems, selected from a review of literature presenting such projects. The results of the evaluation are used to fundament and conceive the design and implementation of a reputation research network, called EERIS - European Research Infrastructures System, which are presented in the second part of the article.
Because the events for adding information that affect the reputation happen less often, it is more efficient to query the reputation which is already stored and calculated on the Blockchain whenever it is needed. At the same time, all the information which compose the reputation are stored on the Blockchain, which makes other organizations handle their own reputation equation which can consist of different data which suits its needs.
This being said, in order to populate the Blockchain with the data the platform already contains, it is needed to do a migration. Hyperledger Fabric, because of the programming languages which can be used to write chaincode, is more powerful and allows integrating libraries or using the core methods, for making API calls, which in this case is considered to be use to initialize the chaincode upon creation.
The conclusions could be used for researchers focusing on different Blockchain educational use-cases, and also for those designing reputation systems for educational actors and entities. | Keywords
