Blockchain for the banking industry examines how distributed ledger technology can transform traditional financial services by enhancing transparency, security, and efficiency in transactions and record-keeping. Research in this area focuses on applications such as cross-border payments, trade finance, fraud detection, loan processing, digital identity verification, and regulatory compliance, where blockchain reduces intermediaries, lowers costs, and accelerates settlement times. Studies highlight how smart contracts automate banking processes, improving trust and minimizing human errors, while cryptographic techniques ensure data privacy and integrity in sensitive financial operations. Challenges such as scalability, interoperability with legacy systems, regulatory hurdles, and cybersecurity risks are also widely discussed, with proposed solutions including hybrid blockchain models, consortium blockchains, and integration with artificial intelligence for risk management. Overall, research papers in this domain aim to provide innovative frameworks that enable secure, transparent, and customer-centric banking services powered by blockchain technology.
