In recent years, the rapid digitization of the banking industry has resulted in an exponential growth of data, presenting numerous challenges related to data security, privacy, and centralized storage. Traditional centralized databases are vulnerable to various security threats, such as unauthorized access, data tampering, and single points of failure. To address these issues, this project proposes a framework for secure banking data storage and retrieval in distributed systems using blockchain technology. The objective of this research is to design and implement a decentralized system that ensures the confidentiality, integrity, and availability of banking data while maintaining scalability, transparency, and efficiency. The proposed framework leverages the immutability, consensus, and distributed nature of blockchain technology to enhance the security and reliability of banking data storage and retrieval. Blockchain is a distributed database or a decentralized ledger that is most commonly used to exchange digital currency and perform transactions securely. Every participant of the network has access to the ledger which will be updated by every new transaction. The Blockchain ledger is a collection of all transactions executed in the past. The Blockchain ledger is a continuously growing tamper-proof data structure containing blocks that hold batches of individual transactions. The completed blocks are added in chronological order. Blockchain via Bitcoin has had a massive impact on the world in the past decade and it’s safe to say that this will continue, especially with many people working tirelessly to remove the various limitations that are prohibiting blockchain from becoming mainstream. One such limitation is the high processing and electrical costs that come from the Proof-of-Work consensus protocol. With ever-evolving technologies, the banking systems can update from their traditional methodologies to a digital, immutable, distributed ledger that can be implemented via Blockchain. Blockchain Technology is a distributed peer-to-peer linked structure that can solve the problem of maintaining and recording transactions in a banking system. Blockchain provides properties like transparency, robustness, suitability and security. The outcome of this research will be a comprehensive framework that addresses the security concerns associated with banking data storage and retrieval in distributed systems. The framework will provide a robust and secure infrastructure for banks to store and retrieve customer data while ensuring privacy, integrity, and availability. The proposed solution has the potential to revolutionize the banking industry by offering enhanced security, transparency, and trust among financial institutions and their customers.
