Electronic voting (e-voting) is a type of voting system that allows voters to cast their ballots electronically. Blockchain technology has the potential to revolutionize e-voting by making it more secure, transparent, and efficient. In this write-up, we will explore how e-voting using blockchain works and its benefits. Blockchain is a distributed ledger technology that enables secure and transparent record-keeping. It allows multiple parties to have access to the same database, and all transactions are recorded and verified through a network of nodes. Blockchain is also designed to be immutable, meaning once a transaction is recorded on the blockchain, it cannot be altered or deleted.
