3. Abstract
● Blockchain technology revolutionizes electronic voting by ensuring
transparency, security, and voter trust.
● Immutable ledger for authenticating votes and preventing tampering.
● Smart contracts streamline processes, reducing errors and fraud.
● Voter anonymity with verifiable audit trails for election authorities.
● Challenges: robust identity verification, secure key management, Sybil attack
prevention.
● Real-world implementations demonstrate enhanced transparency and reduced
costs.
● Collaboration among tech experts, government bodies, and cybersecurity

4. Introduction
A decentralized voting system on the Ethereum blockchain can revolutionize
elections. It offers security, transparency, and tamper-proof records. No need for
intermediaries, making it efficient and less prone to corruption. It allows global
voting, increasing participation and making elections more democratic and
inclusive.

5. Objective
● Security: The proposed system aims to provide a secure platform for
conducting elections, eliminating the possibility of tampering with votes, and
ensuring that the election results are transparent and verifiable.
● Transparency: The proposed system aims to provide complete transparency
to the voters, allowing them to view the entire voting process, including the
vote counting and results.
● Accessibility: The proposed system aims to make the voting process more
accessible to all eligible voters by eliminating the need for physical presence
at a polling station, thus increasing voter turnout.

6. Objective
● Efficiency: The system aims to increase the efficiency of the voting process
by reducing the time and resources required to conduct elections. Since the
system is automated and eliminates the need for intermediaries, it can
significantly reduce the cost and time associated with traditional voting
methods.
● Trust: The proposed system aims to increase trust in the voting process by
providing a transparent and tamper-proof mechanism for recording and
tallying votes.

7. Problem Statement
Traditional voting systems are plagued by issues such as fraud, lack of
transparency, and limited accessibility. As technology advances, the need for a
secure, transparent, and efficient electoral process becomes more apparent.
Leveraging blockchain technology for electronic voting presents an opportunity to
address these challenges. The problem statement addresses the development of a
robust and user-friendly E-Voting System using blockchain that ensures security,
accessibility, and trust.

distribution(2023
).
The process uses the
extraction of information
from the Aadhar database,
voting fingerprints as the
primary authentication
resource to ensure greater
security. It also uses a 128-
bit AES encryption
algorithm and SHA-256 to
provide protection. The
vote is cast in the form of a
contract, and a blockchain
is built to keep track of the
number of votes cast.

The implementation
result demonstrates
a realistic and
reliable e-voting
system that
addresses the issue
of vote forgery during
electronic voting. The
blockchain-based e-
voting system is
more stable and
anonymous than
other e-voting
systems.

The system will ensure Transparency and Trust, enhance the Security of the system,
increase the accessibility for the voters, reduce the cost of voting and will also
potentially prevent voter fraud by eliminating double voting. This system also offers
a auditable and transparent way to verify election results.
