Motivation
- Current voting systems
- Security
- Affordability
- Feasibility

Objective
Create an EndToEnd verifiable e-voting system that is:
- Secure
- Anonymous
- Transparent
- Non-revocable
- Increase voter turnout

About Blockchain
- Peer to peer network
- Blockchain database
- Ethereum TestRPC Blockchain
- Centralised systems
- Decentralised system

Smart Contract
- Stores data on Blockchain
- Cannot be redeployed
- Each voter is given and address
- Each address has tokens
- An array to keep track of votes

Decentralised Application (DApp) created using Truffle

Implementation
- We assume each voter is given a key from the government
- Using this key the user votes by creating a transactions on the
Blockchain, whilst upholding voter anonymity
- The voter can verify their vote using their key and lookup their vote in the
sequence of transactions creating transparency
- Transactions on the blockchain are non-revocable thus creating a verifiable

Implementation of Smart Contract
- Use of struct datatype for voter. This records the address of the voter, the tokens
available, and the votes cast under that address
- Allow the voter to vote for a candidate
- Store this new data on the Blockchain
- Retrieve and display this data on the user interface

Automated testing for large number of voters
and Demo

- Public website onto domain and host
- Voter verification on Blockchain
- Open source code
- Change your vote and vote early
Limitations
- Scaling to large number of voters

This document proposes a blockchain-based truthful incentive mechanism for distributed peer-to-peer applications. It uses blockchain to store transactions and reward intermediate nodes that successfully deliver messages. The mechanism uses cryptographic techniques like commutative encryption to securely verify transactions. Game theory is used to analyze the security of the mechanism and show it is resistant to cheating like not forwarding messages or falsely claiming receipt. Future work could address sender-receiver collusion and introduce reputation and privacy into the scheme.

This research is based on generating the lottery system software. The existing system of lottery is done manually in a majority. Thus in this computerized and technological world there is an urgent need for the improvement of the lottery system also. Thus introduces a novel approach for developing a software for lottery system using block chain which is one of the most security granted, decentralized technology. It includes the selling, purchasing, declaration of result . Here the randomness and fairness of declaring result is ensured and thereby providing a tamper-resistant, transparent and efficient system. Here we introduce a smart contract based system that include registration, purchasing, prize declaration, lottery claiming, and payouts. This paper put forth a blueprint of a novel lottery system hinged on Block chain technology, that coalesce lottery operations models and block chain mechanisms

A novel smart contract based blockchain with sidechain for electronic voting

IJECEIAES

Several countries have been researching digital voting methods in order to overcome the challenges of paper balloting and physical voting. The recent coronavirus disease 2019 (COVID-19) epidemic has compelled the remote implementation of existing systems and procedures. Online voting will ultimately become the norm just like unified payments interface (UPI) payments and online banking. With digital voting or electronic voting (e-voting) a small bug can cause massive vote rigging. E-voting must be honest, exact, safe, and simple. E-voting is vulnerable to malware, which can disrupt servers. Blockchain’s end-to-end validation solves these problems. Three smart contracts-voter, candidate, and voting-are employed. The problem of fraudulent actions is addressed using vote coins. Vote coins indicate voter status. Sidechain technology complements blockchain. Sidechains improve blockchain functionality by performing operations outside of blockchains and delivering the results to the mainchain. Thus, storing the encrypted vote on the sidechain and using the decrypted result on the mainchain reduces cost. Building access control policies to grant only authorized users’ access to the votes for counting is made simpler by this authorization paradigm. Results of the approach depict the proposed e-voting system improves system security against replay attacks and reduces the processing cost as well as processing time.

Blockchain is a distributed ledger of transactions or digital events that is shared among participants in a network. Each transaction is verified by consensus of participants and stored in a chronological and immutable chain of blocks. Blockchain technology was introduced with Bitcoin in 2008 as a way to record cryptocurrency transactions in a verifiable and permanent way without the need for a central authority. Common applications of blockchain include cryptocurrencies, smart contracts, supply chain management, digital identity, and decentralized systems.

SECURE BLOCKCHAIN DECENTRALIZED VOTING FOR VERIFIED USERS

IJNSA Journal

The paper focuses on introducing a decentralized e-voting scheme that uses blockchain to achieve security and anonymity. A blockchain network based on Ethereum was applied, to provide a decentralized and distributed database based on the Peer-to-Peer architecture. During the implementation, smart contracts were used. Thanks to this, it is possible to code the terms of the contract required to perform the transaction. The proof-of-concept implementation uses the blind signature protocol and encryption with the RSA algorithm. Presented in this paper scheme for blockchain decentralized voting is fully implemented and potential issues are analyzed and discussed.
