Information Technology has played a significant role in the evolution of financial markets in recent decades, altering the way financial organizations communicate with one another. However, when amazing breakthroughs like as Blockchain mature, the sector's traditional processes and conventions may be completely overhauled. The core of Blockchain is that it is a public, shared, and meticulously structured ledger that enables mutually unknown people and organizations to exchange data in a secure ledger and conduct various transactions. Cryptography and peer-to-peer network technologies have been combined to create this groundbreaking breakthrough. It is almost impervious to the bulk of today's cyber-threats. Blockchain-based solutions have found their way into a variety of sectors, including real estate, health care, the media, and government agencies. This article will describe how Blockchain works, what it is, its kinds, applications, and use of blockchain in business. Future scope of this result is that Blockchain is gaining traction across a wide range of businesses, and blockchain engineers and developers will be in high demand in all of them. Blockchain is predicted to reach a $20 billion business by 2024. As a result, Blockchain integration into core operations is something that industries are ready to do. Not only is distributed ledger technology, particularly Blockchain, transforming the monetary industry, but it is also making the financial system more transparent.
