Blockchain is a technology that decentralizes the whole system and the database is owned by every node. It offers immutable distributed ledger technology which is an exciting advancement in the field of the information technology world in this research we aim to discuss a decentralized online voting system using blockchain technology. Using this we create a decentralized, secure and easy way of voting.
