This is where blockchain, a decentralized and immutable digital ledger, can play a vital role. By leveraging blockchain technology, electronic voting systems can enhance transparency, security, and trust.

How Blockchain Works

Blockchain is a distributed ledger that records transactions in a transparent and secure manner. It consists of a chain of blocks, each containing a list of transactions. These blocks are linked together using cryptographic hashes, forming a tamper-proof chain of information. Key features of blockchain, such as decentralization, immutability, and consensus mechanisms, ensure the integrity of the recorded data.

Blockchain is a revolutionary technology that operates on the principles of decentralization, transparency, and immutability. At its core, blockchain is a distributed ledger that records transactions in a transparent and secure manner. Instead of relying on a central authority, such as a bank or government, blockchain relies on a network of computers, known as nodes, to validate and verify transactions. Each transaction is bundled into a block and linked together in a chronological chain, creating a tamper-proof record of all transactions.

One of the key features of blockchain is its transparency. Once a transaction is added to the blockchain, it becomes visible to all participants in the network. This transparency enhances trust and accountability, as anyone can verify the authenticity of a transaction. Additionally, blockchain’s decentralized nature ensures that there is no single point of failure or control. The distributed nature of the network makes it highly resilient to attacks and manipulation.

Furthermore, blockchain ensures immutability, meaning that once a transaction is recorded on the blockchain, it cannot be altered or deleted. This feature provides a high level of security and prevents fraud or unauthorized changes to the data. Overall, blockchain’s unique architecture and principles make it a powerful and transformative technology with numerous applications beyond financial transactions.

Challenges in Electronic Voting

Traditional electronic voting systems face several challenges, including the lack of verifiability and trust.
