INTRODUCTIONIn a world full of rising technologies, ‘Blockchain technology’ (often conversationally referred to as ‘Blockchain’) is arguably one among the foremost exciting, being labelled as ‘disruptive’ and ‘innovative’ by several. A blockchain is actually a growing database of records or public ledger of all transactions or digital events that are already executed and shared among collaborating parties. Every transaction within the public ledger is verified by agreement of a majority of the participants within the system. And, once entered, data can not be erased. The blockchain contains an explicit and verifiable record of each single transaction/dealing ever made. It wasn’t long ago technology enthusiasts had known of cryptocurrencies like ‘Bitcoin’ and ‘Litecoin’, however, cryptocurrencies have currently entered into the limelight, and the underlying technology –’Blockchain’ has received attention from a range of industries.The construct of recording transactions in a very secure, stable and ascendible approach, has LED to attainable applications in areas including: sensible contracts, management, digital plus management, and identity management. Moreover, Blockchain technology has the potential to be crucial in industries like property, automotive, healt aid and even the diamond business.Bitcoin (the decentralized peer- to- peer digital currency) is history’s initial permanent, localised, global, trustless ledger of records. Since its invention, entrepreneurs in industries round the world have come back to grasp the implications of this development. Bitcoin is the most well-liked example that uses blockchain technology. The digital currency bitcoin itself is extremely controversial however the underlying blockchain technology has worked cleanly and found wide selection of applications in each money and non money world.The report will concentrate on how a Blockchain works from a technical viewpoint, with stress on how it achieves distributed consensus. Moreover, the report can offer an in depth explanation on how Blockchain technology ensures a secure and trustable record of transactions. The report will check out already established uses of Blockchain technology, furthermore as any fascinatingand profitable areas of emerging/potential uses,the benefits, disadvantages and risks of exploiting .Blockchain wil lalso be evaluated.Although Blockchain is receiving lots of attention, it’s still unclear whether or not it is profitable.APPLICATIONS OF BLOCKCHAINBlockchain is best known for being the technology behind cryptocurrencies like Bitcoin and Ether (the currency of Ethereum), but blockchain is much more than an instrument of finance. Blockchain is a clerking platform or ledger that’s incorruptible, enforces transparency, and bypasses censorship. By confronting problems with financial, political and institutional corruption, this has the potential to make huge social change—and greatly shield the human rights of each individual.FUTURE RISKS The basis of BlockChain technology relies on the very fact that it is mathematically impossible for a single party to crack the system due to lack of needed computational power. But with the advent of  Computers ( in future ), the cryptographic keys may be easy enough to crack through sheer brute force approach within a reasonable time. This will bring the whole system to its knee. The counter-argument would be for keys to become even stronger so that they may not be easy to crack.ADOPTION OF BLOCKCHAINBlockchain is the technology backbone of Bitcoin. The distributed ledger functionality coupled with security of BlockChain, makes it very attractive technology to solve the current financial as well as non-financial business problems. There is enormous interest in BlockChain based business applications and hence numerous Startups working on them. The adoption definitely faces strong headwind as described before. The large Financial institutions like Visa, Mastercard, Banks, NASDAQ, etc., are investing in exploring application of current business models on BlockChain.
