In the paper, we can implementing innovative log storage system that makes use of smart contracts, Proof of Stake (PoS) consensus, and Blowfish encryption on a blockchain. PoS involves stakeholders in transaction validation based on their interest in the network, which improves security and energy efficiency. Logdata is protected from breaches and unwanted access with blowfish encryption. The Ethereum Blockchain Network uses Proof of Stake (PoS) to preserve network integrity and enable file retrieval requests. The Interplanetary File System (IPFS), which offers decentralized storage and censorship resistance, is used to store encrypted log data. Data integrity is confirmed using content addressing. Automating user registration while maintaining transparency and accountability is possible using a smart contract architecture. This comprehensive approach is perfect for businesses looking for cutting-edge blockchain solutions for user registration and logstorage since it puts data security, integrity, and system scalability first.
