This immutable nature ensures transparency and fosters trust between participants.
The decentralized nature of blockchain allows a network of participants to maintain a public ledger without the need for a centralized authority. This ensures that no single entity has control over the entire chain, providing security and reducing the risk of fraud. Smart contracts, self-executing contracts with the terms of the agreement directly written into code, provide transparency and can automate transactional processes on the blockchain, such as Ethereum.
The Evolution of Blockchain in Voting
The application of blockchain technology within voting systems signifies an effort to enhance electoral transparency and security. It started with the advent of Bitcoin, which demonstrated the feasibility of a secure and decentralized transaction ledger. Building on this concept, voting systems seek to use blockchain to create a verifiable and unfalsifiable record of votes, making the voting process more transparent and stronger against tampering efforts.
The evolution from Bitcoin’s application to broader uses such as electronic voting demonstrates blockchain’s versatility. Incorporating blockchain into voting systems can potentially increase trust among voters by ensuring that their ballots are counted accurately and remain unchanged. This immutable record of votes could lead to an increase in electoral participation by reinforcing the integrity of the election process.

How Blockchain Voting Works
Blockchain-based voting leverages a distributed ledger for recording votes as transactions. Once a voter casts their vote, it is encrypted and transmitted to the blockchain network. Nodes within the network verify the transaction using consensus algorithms, ensuring only valid votes are recorded. This ledger is immutable—once a vote is recorded, it cannot be altered, ensuring the integrity of each vote.
Role of Cryptography in Secure Voting
Cryptography is the cornerstone of security for blockchain-based electronic voting systems. It ensures votes are kept confidential while being cast, encrypted for protection, and can be verified without revealing the voter’s identity. Advanced cryptographic techniques, such as homomorphic encryption, allow for votes to be aggregated and counted without decryption, adding a layer of privacy to the voting process.
Smart Contracts and Voting
Smart contracts are self-executing contracts with the terms of the agreement directly written into code. In the context of online voting, smart contracts handle the authentication of voters and tally votes once conditions are met, without human intervention.
