Blockchain technology is transforming banking by enhancing transparency and trust through distributed ledger technology (DLT). This review explores how blockchain-driven communication improves transparency and trust in banking by providing a secure, immutable, and decentralized record of transactions. Blockchain ensures that all transactions are transparent, reducing fraud and building trust among customers and stakeholders. It also enhances trust by creating tamper-proof and auditable records, which are crucial in an industry where trust is essential. Blockchain enables real-time transactions and data sharing, streamlining processes and reducing costs. It is being used in various banking applications, including cross-border payments, trade finance, and KYC processes. Smart contracts automate transactions based on predefined conditions, improving efficiency and reducing errors. Blockchain also enhances transparency in customer service, product offerings, and regulatory compliance by providing a secure and transparent record of all transactions. Despite its benefits, blockchain faces challenges such as scalability, regulatory compliance, and integration with existing systems. Addressing these challenges requires collaboration between banks, regulators, and technology providers. Strategies include implementing scalability solutions, developing interoperability standards, and ensuring compliance with regulations. The future of blockchain in banking is promising, with advancements in technology expected to enhance transparency, trust, and efficiency. Trends such as DeFi, CBDCs, and tokenization are likely to shape the future of blockchain in banking. Banks are encouraged to adopt blockchain technology to remain competitive and provide secure, transparent, and efficient services. As blockchain continues to evolve, it has the potential to revolutionize the banking industry, making communication more transparent, efficient, and secure.Blockchain technology is transforming banking by enhancing transparency and trust through distributed ledger technology (DLT).
