Revolutionizing Lottery Systems with Blockchain: A Secure and Tamper-Proof Solution

Abstract

Existing traditional lottery systems are often prone to issues of fraud, transparency and centralized authority, which compromise the degree of fairness and security involved in the lottery process. The current work offers a blockchainbased traditional lottery system that is based on smart contracts and offers a decentralized, tamper-proof and transparent environment. Using cryptographic hashing and distributed ledger technology, the proposed system eliminates intermediaries, reduces operating costs by as much as 35 % and increases user trust by 87 %. The automated functioning of smart contracts means that the entire lottery process from the issuance of tickets to how winners are chosen and paid is immutable and verifiable. The proof-of-concept implementation using Ethereum and solidity demonstrated improvements in efficiency, such as shortening the payout time from$24-48$hours to less than 10 seconds and exhibiting 100 % resistance to known smart contract vulnerabilities. The empirical evidence highlights the potential of blockchain technology to transform the way digital lotteries are conducted by providing the benefits of security, fairness and transparency.
