A format called Blockcerts is used to manage certifications kept on the Blockchain. Your initial Blockcerts are most likely what you are going to withdraw, but you may also gather more. For this reason, it's critical to have a location to keep them: a portfolio for your Blockcerts, independent of the organization that bestows the recognition (such as the university) or the platform that the organization uses (such as Bestr).
The Blockcerts Wallet app is available for download on Google Play and the App Store.
