Blockchain technology, often associated with cryptocurrencies like Bitcoin, is increasingly being integrated into the financial sector. This paper explores how Blockchain impacts business transactions and enhances transparency within the financial industry. By examining the underlying principles of Blockchain—decentralization, immutability, and consensus mechanisms—this paper discusses how these features contribute to greater transparency, trust, and efficiency in financial transactions. Case studies of its current applications, as well as potential future trends, are also analyzed. Consequently, we discovered in our study that the implementation of Blockchain has resulted in substantial reductions in transaction processing time, transaction costs, fraud, and transparency. However, the main obstacles to greater adoption continue to be security concerns, scalability problems, and regulatory obstacles. For Blockchain technology to continue to advance and be included into global financial institutions, several challenges must be overcome.
