A. Implementing blockchain technology Blockchain technology, is designed to provide end-to-end integrity for transactions

Multi-factor authentication (MFA) is a security measure that requires users to provide multiple forms of identification before granting access to a system. This adds an extra layer of security beyond just a username and password, making it more difficult for unauthorized individuals to access financial transactions. MFA typically involves a combination of something you know (like a password) and something you have (like a mobile device or a security token). While blockchain technology, integrated audit facilities, and audit trail logs are also important components of a secure financial system, multi-factor authentication directly addresses the challenge of verifying the identity of users during online transactions, which is crucial for maintaining the integrity of financial transactions.
