2. ABSTRACT
oVoting is a pillar of modern society, but the traditional paper voting
system is prone to fraud and failure.
oThe primary goal of every democratic nation is to conduct free,
systematic, and impartial elections.
oBlockchain technology offers transparency and security, making it
suitable for impartial elections.
oBlockchain is a decentralized, immutable ledger system that ensures
transparency and security in voting processes.
oThe objective of this paper is to develop a voting system that leverages
Blockchain technology to provide transparency and security.
oOnline voting systems enable voters to cast their ballots from any location
and at any time, thereby increasing voter participation.

3. EXISTING SYSTEM
• The existing system uses a conventional web based application for casting votes of
the individuals.
• In an electronic voting application the voters can easily use their voting rights online.
• They must be registered first to be able to vote. The system administrator registers
everyone mainly for security reasons.
• The verification of the individual is done using existing databases such as aadhar,
pan-card, passport, etc.
• Web-based systems are susceptible to hacking, data breaches, and unauthorized
access. Sensitive voter information could be compromised.
• Web-based voting may raise privacy issues, as voters might be hesitant to share
personal data online. Ensuring anonymous voting is challenging.

4. PROPOSED SYSTEM
• The block-chain based voting system aims to provide secure, transparent, and
tamper-proof voting using blockchain technology. It ensures voter privacy,
verifiability, and end-to-end integrity.
• It utilize a public or permissioned blockchain network like Ethereum
• Nodes represent election authorities, voters, and validators
• Web or mobile application for voters to cast their votes. It authenticate voters
securely using cryptographic keys.
• Voters submit their votes via the interface. Votes are encrypted and recorded
on the blockchain.
• This system uses zk-snarks algorithm and Etherium block chain network.

5. LITERATURE REVIEW

6. INTRODUCTION
Political voting requires a transparent, secure, and easy voting methodology. Voting can be
applied in either a paper based or digital systems. The current voting systems face different
challenges, such as vote tampering, which is due to the process of collecting and counting paper-
based votes. Moreover, malicious acts can exploit voting data and procedures. There is a need for
secure and transparent elections, such as integrating Blockchain technology in this process . The use
of Blockchain in elections will be able to process elections faster, perform a more transparent audit,
and might reduce the cost and the time consumed during the election process. Voting embodies one
of the most prevalent phenomena not only from a historical perspective but also in the modern-day
society.
Blockchain technology is currently a new technology that is being implemented around the
world, and people use it because it saves time, money, and secures data. The blockchain is
distributed, so this makes it decentralized and allows for data to be shared across different entities,
which saves much time. Also, blockchain is mostly private one meaning that only authorized
participants can have access to the blockchain ledger. Another main feature of the blockchain is
immutability since it is chained together. Every new block has a hash of the previous block; it does
not allow deletion or update to the existed records in the blockchain .
