Marksheet Validation Using Blockchain
Blockchain can be explained as a growing list of records called blocks, a block is linked to its previous block and its following block using cryptography.
Each block in blockchain contain a cryptographic hash of the previous block, data and a timestamp. The data in blockchain is temper proof. It is an open distributed ledger that records data in a permanent and verifiable way. Blockchain is managed by a peer-to-peer network collectively adhering to a protocol for internodes communication and validating new blocks. Once the data is recorded in block, it can't be altered without alteration of all successive blocks in blockchain, which requires permission of the network majority (which contains all peer-to-peer networks). Blockchain can be used in digital identity, tokenization, financial markets, inter-organizational data management and many more. Marksheet validation can be done using blockchain by creating blocks of data of student that contain parameters such as Name, Roll no, Semester, Grades, Exam type.
