Abstract

An online voting system that utilizes blockchain technology is a promising solution for conducting elections in a secure and transparent manner. The decentralized and distributed nature of the blockchain ledger ensures that every vote is recorded accurately and cannot be tampered with or altered without detection. This is because every node on the blockchain network has a copy of the ledger, making it virtually impossible to manipulate election results. One of the biggest advantages of blockchain-based voting systems is that they allow voters to cast their ballots from anywhere, as long as they have an internet connection. This makes voting more accessible and convenient for people who might have difficulty getting to a polling station. Additionally, blockchain technology allows for the verification of voter identity and prevents double voting, ensuring that every vote is legitimate and counted accurately. Another benefit of blockchain-based voting systems is their resistance to cyber attacks. The decentralized nature of the blockchain network makes it extremely difficult for hackers to compromise the system, as they would need to gain control of a majority of the nodes on the network. Additionally, the transparent nature of blockchain-based voting systems makes them more trustworthy and helps to prevent voter fraud. Overall, the use of blockchain technology in online voting systems has the potential to revolutionize the way we conduct elections and safeguard the integrity of democracy. By providing a secure and transparent method for conducting elections, blockchain-based voting systems can help to increase voter participation and ensure that every vote is counted accurately.

Introduction

I. INTRODUCTION

The traditional method of conducting elections has been through in-person voting at a polling station. However, as society becomes increasingly digital, the need for a more accessible and convenient method of voting has emerged. Online voting has been proposed as a solution to this problem, but concerns surrounding security and transparency have hindered its widespread adoption. Enter blockchain technology, a decentralized and distributed ledger system that provides a secure and transparent method for recording transactions. With its built-in security features, blockchain technology has the potential to provide a tamper-proof system for online voting, ensuring that every vote is counted accurately and that the results of an election are trustworthy.

Blockchain-based online voting systems work by recording each vote on a decentralized ledger that is accessible to all nodes on the network. Each vote is encrypted and signed using a private key, ensuring that it cannot be tampered with or altered without detection. This provides a level of security that traditional voting systems cannot match, as there is no central point of failure that can be exploited by hackers. One of the biggest advantages of blockchain-based online voting systems is their accessibility. Voters can cast their ballots remotely, from anywhere with an internet connection. This makes voting more convenient for people who might have difficulty getting to a polling station, such as those with disabilities or those who live in remote areas.

Another benefit of blockchain-based online voting systems is their ability to verify voter identity and prevent double voting. By using a combination of encryption and digital signatures, blockchain technology can ensure that every voter is who they claim to be and that they can only cast one vote.

II. LITERATURE REVIEW

Issues and Effectiveness of Blockchain Technology on Digital Voting: System presented in the Issues and Effectiveness of Blockchain Technology on Digital Voting that block chain is a technology that enables moving digital coins or assets from one individual to other individual. Blockchain concept can be understand with the concept of linked list in Data Structure, because its next key address are stored in previous key and they are linked with each other. [1]

Electronic voting machine based on Blockchain technology and Aadhar verification: System presented in the Electronic voting machine based on Blockchain technology and Aadhar verification that A nation with less voting percentage will struggle to develop as choosing a right leader for the nation is very essential. Our proposed system designed to provide a secure data and a trustworthy election amongst the people of the democracy. Since aadhar card is the most needed for a person identity hence deploying an election process using it is highly recommendable. Blockchain will be publicly verifiable and distributed in a way that no one will be able to corrupt it.[2]

For e-voting to become more open, transparent, and independently auditable, a potential solution would be base it on block chain technology. This paper explores the potential of the block chain technology and its usefulness in the e-voting scheme. an e-voting scheme, which is then implemented. [3]

Design of Distributed Voting Systems: System present the Design of Distributed Voting Systems. Electronic voting systems attempt to be as easy to use and secure as ideal traditional elections and attempt to eliminate the human errors described. [4]

A secure end-to-end verifiable e-voting system using zero knowledge based blockchain: System presented in the secure end-to-end verifiable e-voting system using zero knowledge based blockchain that present a cryptographic technique for an authenticated, end-to-end verifiable and secret ballot election. Voters should receive assurance that their vote is cast as intended, recorded as cast and tallied as recorded. The election system as a whole should ensure that voter coercion is unlikely, even when voters are willing to be influenced. Currently, almost all verifiable e-voting systems require trusted authorities to perform the tallying process. An exception is the DRE-i and DRE-ip system. The DRE-ip system removes the requirement of tallying authorities by encrypting ballot in such a way that the election tally can be publicly verified without decrypting cast ballots. However, the DRE-ip system necessitates a secure bulletin board (BB) for storing the encrypted ballot as without it the integrity of the system may be lost and the result can be compromised without detection during the audit phase.[5]

C. Proposed Algorithm/Methodology 

Algorithm 1 : Hash Generation

Input : Genesis block, Previous hash, data d,

Output : Generated hash H according to given data

Step 1 :  Input data as d

Step 2 : Apply SHA 256 from SHA family

Step 3 : CurrentHash= SHA256(d)

Step 4 : Return CurrentHash

This algorithm outlines the steps needed to generate a hash using SHA-256 from the SHA family. The input includes a genesis block, a previous hash, and the data d, while the output is the generated hash H according to the given data.

In Step 1, the data is input as d. This can be any type of data, such as a transaction or a block header.

In Step 2, the SHA-256 algorithm is applied to the input data. This is a cryptographic hash function that creates a fixed-length output, known as a hash, from any input data.

In Step 3, the output of the SHA-256 algorithm is stored as the current hash, represented by the variable CurrentHash.

Finally, in Step 4, the algorithm returns the CurrentHash as the generated hash H according to the given data.

This algorithm is a crucial component of blockchain technology, as it helps to ensure the integrity of the data stored on the blockchain. By using a cryptographic hash function like SHA-256, each block on the blockchain is linked to the previous block in a tamper-proof way. Any attempt to modify the data in a block would result in a different hash, breaking the link to the chain and alerting the network to the attempted tampering.

Algorithm 2 : Protocol for Peer Verification

Input : User Transaction query, Current Node Chain CNode[chain], Other Remaining Nodes blockchain NodesChain[Nodeid] [chain],

      Output : Recover if any chain is invalid else execute current query

      Step 1 : User generate the any transaction DDL, DML or DCL query

      Step 2 : Get current server blockchain

             Cchain ß Cnode[Chain]

      Step 3 : For each

     End for

     Step 4 : Foreach (read I into NodeChain)

             If (!.equals NodeChain[i] with (Cchain))

                   Flag 1

     Else Continue Commit query

     Step 5 : if (Flag == 1)

           Count = SimilaryNodesBlockchian()

     Step 6 : Cacluate the majority of server

              Recover invalid blockchin from specific node

     Step 7: End if

              End for

              End for

This algorithm outlines the steps needed to verify the integrity of a blockchain by checking it against other nodes in a peer-to-peer network. The input includes a user transaction query, the current node chain CNode[chain], and the remaining nodes in the blockchain NodesChain[Nodeid][chain]. The output is either to recover if any chain is invalid, or else execute the current query.

In Step 1, the user generates a transaction query, which can be a DDL, DML, or DCL query.

In Step 2, the current server blockchain is obtained by assigning it to the variable Cchain, which is equal to CNode[chain]. This ensures that the current node is using the correct blockchain.

In Step 3, a loop is initiated to iterate over all the nodes in the network.

In Step 4, another loop is initiated to read each node's blockchain, represented by the variable NodeChain[i]. If the NodeChain[i] is not equal to Cchain, then Flag is set to 1, indicating that there is an invalid blockchain in the network. Otherwise, the algorithm continues to commit the query.

In Step 5, if Flag is equal to 1, then the algorithm proceeds to calculate the majority of the servers that have the same blockchain, represented by the variable Count.

In Step 6, once the majority of servers with the same blockchain is computed, the algorithm recovers the invalid blockchain from a specific node.

Finally, in Step 7, the algorithm ends the loop and continues to execute the query.

This algorithm is critical for maintaining the integrity of the blockchain and preventing fraudulent activities, such as double-spending and tampering with transaction records. By verifying the blockchain with other nodes in the network, the algorithm ensures that the blockchain is valid and that the transactions are secure.

Mining Algorithm for valid hash creation

Input : Hash Validation Policy P[], Current Hash Values hash_Val

Output : Valid hash

Step 1 : System generate the hash_Val for ith transaction using Algorithm 1

Step 2 : if (hash_Val.valid with P[])

              Valid hash

               Flag =1

Else

           Flag=0

             Mine again randomly

Step 3 : Return valid hash when flag=1

This algorithm outlines the steps needed to mine a valid hash for a given transaction. The input includes the Hash Validation Policy P[] and the current hash values hash_Val, and the output is a valid hash.

In Step 1, the system generates the hash value for the ith transaction using Algorithm 1. This hash value is represented by the variable hash_Val.

In Step 2, the algorithm checks if the hash_Val is valid with the Hash Validation Policy P[]. If the hash_Val is valid, then the algorithm returns the valid hash and sets the flag to 1. Otherwise, if the hash_Val is not valid, the algorithm sets the flag to 0 and mines again randomly until a valid hash is found.

In Step 3, once the flag is set to 1, the algorithm returns the valid hash.

The mining algorithm is used in blockchain technology to create new blocks in the chain. In order to add a new block to the chain, miners must solve a complex mathematical problem that involves finding a hash value that meets a certain criteria, as defined by the Hash Validation Policy. This algorithm is responsible for generating a valid hash value based on the given policy and current hash values.

The mining process is computationally intensive, which ensures the security of the blockchain. Miners compete with each other to solve the problem, and the first one to find a valid hash is rewarded with newly generated cryptocurrency and transaction fees. The mining algorithm is a crucial component of the blockchain, as it ensures the integrity of the transactions and the security of the network.
