Blockchain is growing as a potentially Out of line force capable of changing the financial services industry by making the fund transfer immediate, cheaper and more secure. Current existing system is not secure enough to give 100% fraud protection because of more manual work and lack of security of data. Blockchain is nothing but a chain made of blocks (nodes).These process node does the all major work. These blocks are connected to each other using cryptography. This system will be more expeditious, more efficient, and has user affectional interfaces in the banking and has zero probability of losing data while processing of the user data. In integration to enabling trade, block chain is larceny-and tamper-resistant model, it eliminates errors and the duplication, blockchain is ideal for reserving the data in blocks and using a tamper-proof hash format, so the data can be securely stored by bank and make the current existing system much more secure and faster.Which is already done in case of cryptocurrency.
