Blockchain technology is being used in banking in several ways: for cross-border payments, trade finance, and new financial instruments. It can streamline processes, save costs, and open new opportunities. Blockchain may revolutionize banking by making transactions more efficient and secure, payments faster, and the system more transparent while reducing fraud and costs for banks and customers. Key applications include expedited international transfers, increased security, reduced costs, fewer errors, eliminating middlemen, person-to-person transactions, fundraising, identity verification, and transaction tracking.
