Assignment description
You probably had to earn quite a few credits through your school education, in order to get to this point of graduation. And soon you will be in possession of an official diploma. Beautiful and formal on paper, but what if you want to share this with an employer? Or share on your socials? (Linked-in for example) that is difficult. That is why we want to develop a method to mint your diploma and education achievements as an NFT. Yours forever safe, valid and verifiable. We want to do this on a well-known / supported blockchain, we have a preference for Etherium, Solana, or Near, do you have a better alternative we are open to that of course!

  • The NFT must comply with the basis of the standard Open Badges.
