Abstract: Ensuring security in every aspect of transactions the primary task of today’s world. Blockchain Technology is used to ensure that digital assets cannot be modified and are transparent by using decentralized hashing techniques. In today’s world, Higher Educational Institutions are competing with others by means of accreditation. As a part of this process, the best outgoing student is awarded based on his/her performance throughout the four years attributed to academics, co-curricular and extra-curricular activities. The proposed system is a multifaceted application which works on the basis of providing credits. This system is implemented using Blockchain so that a ledger is distributed among all the users connected in the network, which ensures data manipulation is impossible. Based on the number of credits a student has gained, they will be provided with certain benefits. A staff is provided with administrative access to the application as they are entitled to generate a unique ID for every student. Staff also verifies the authenticity of the certificates that are being uploaded by the students which are hashed using MD5 and are appended to the existing chain. Each block in the chain is hashed using SHA-256 algorithm. A leaderboard can be viewed by the students along with the provision to view their individual scores. The student who tops the leaderboard at the end of the final year will be the best outgoing student of that batch.
