# ChainVote: Blockchain-Based E-Voting System
---
## Project Description
This project explores the development of a **secure, transparent, and verifiable blockchain-based electronic voting (e-voting) system** aimed at addressing the challenges of traditional paper-based and centralized electronic voting systems. By leveraging blockchain technology, the system ensures **ballot secrecy, voter verifiability, contestability, and auditability**, making elections more secure and resistant to tampering.
The research involves a **comprehensive analysis of existing e-voting systems**, expert interviews with blockchain and cybersecurity professionals, and case study evaluations to identify potential improvements. A prototype of the e-voting system will be developed and tested with a controlled user group to assess **usability, security, and scalability**.
### Key Objectives
✅ **Enhancing security** by preventing fraud and unauthorized modifications to votes
✅ **Ensuring transparency** through a decentralized and immutable ledger
✅ **Providing voter verifiability** without compromising ballot secrecy
✅ **Analyzing usability and accessibility** through user feedback and expert reviews
Through this research, we aim to contribute to the **future of digital democracy** by demonstrating the feasibility of blockchain-based e-voting systems while addressing potential challenges and limitations.
## High-Level System Architecture
There are three system states:
1. **Pre-Election**
- Voter Registration and Authentication
- Candidate Registration
2. **During Election**
- Voting Phase
3. **Post-Election**
- Result Counting and Publishing
---
### Voter Registration and Authentication
The Voter Registration Module verifies voter identities and securely assigns cryptographic voting keys. This module interacts with the election commission database to store voter records securely.
**Components:**
- **Election Commission (EC):** Responsible for verifying and registering voters.
- **Secure Voter Database:** Stores voter details (not on the blockchain).
- **Threshold Cryptography Key Generation:** Splits the voter’s key into two parts.
- **Blockchain:** Stores only the hashed voter key for verification.
**Process Flow:**
1. Voter submits registration details.
2. EC verifies identity and generates a voting key pair using threshold cryptography.
3. One part of the key is sent via registered mail; the other is stored in the database and used at the polling station.
4. The hashed key is stored on the blockchain for verification.
---
### Candidate Registration
The Candidate Registration Module ensures only eligible candidates are registered and that their details are securely stored on the blockchain.
**Components:**
- **Election Commission:** Verifies and approves candidate applications.
- **Candidate Database:** Stores candidate details securely.
- **Blockchain:** Stores candidate names, party affiliations, and assigned candidate IDs in the genesis block.
**Process Flow:**
1. Candidates submit their application with the required documents.
2. EC verifies eligibility and assigns a unique candidate ID.
3. Candidate details are added to the private blockchain to ensure immutability.
---
### Voting Process
The Voting Module enables voters to cast encrypted votes securely using threshold cryptography and homomorphic encryption.Encrypted votes are recorded on the blockchain.
**Components:**
- **Voter Authentication:** Voters must provide both key parts for authentication.
- **Encrypted Ballot Casting:** Votes are encrypted using homomorphic encryption.
- **Blockchain:** Stores encrypted vote.
**Process Flow:**
1. Voter authenticates using both key parts.
2. Voter selects a candidate.
3. Vote is encrypted using homomorphic encryption and stored on blockchain.
---
### Counting and Result Publication
The Counting & Result Module aggregates encrypted votes off-chain using homomorphic encryption and publishes the final result on the blockchain.
**Components:**
- **Homomorphic Vote Aggregation:** Computes results without decrypting individual votes.
- **Threshold Decryption:** Only the final tally is decrypted using multi-party decryption.
- **Blockchain:** Stores final election results and enables public verification.
- **Web Interface:** Displays results in a verifiable and transparent manner.
**Process Flow:**
1. Encrypted votes are retrieved from blockchain.
2. Homomorphic encryption is used to compute vote tallies without decryption.
3. The final tally is decrypted and stored on blockchain.
4. The results are displayed via a secure web interface.
