Abstract:
Blockchain is nowadays one of the most emerging fields in the computer science technology for data storage and transaction on online data among researchers and
academics for the recent years. Hence, Blockchain implementation on exam result
storage database is demandable field to work on. Aim of this thesis is to create a web
application to store exam results data using blockchain that can perform to store data
by an owner who have the authority to input the data and the other users would only
view the data using their hash id. Here, I have used an Ethereum smart contract which
is written by solidity programming language to create a contract that perform or execute
the code based on some given conditions. I have used ganache framework for testing
and debugging and development purpose of the smart contract. I have used the web3.js
library which is the official Ethereum JavaScript API. It is used to interact with
Ethereum smart contracts and some html and CSS codes for designing purpose. In this
thesis I have successfully create a web application. And in the backend part it stores
data using the blockchain cryptography. As in recent we are more concerned about
securing our data storage because of tampering issues. Exam result tampering is
nowadays a common problem in our country and so blockchain implementation in
exam result storage database is a noteworthy task. Therefore, our study has highlighted
the research studies in the field of decentralized and distributed ledger in exam results
database.
