The blockchain is a decentralized transaction and managing the data. This technology introduced on the first for Bitcoin cryptocurrency which makes more easier for the transaction. Blockchain technology has highly raised up in 2008. The main purpose of the Blockchain technology is to provide security, anonymity and data integrity without any third party organization in control of the transactions. This helps on improving in research areas especially from the perspective of technical challenges and limitations. In this research, we have conducted survive mapping study with the goal of presenting the Blockchain technology. The main objective of the researchers is to make the challenges in understanding the current research areas. This the future way to developing more and more on Blockchain technology. A blockchain is just a chain and list of blocks which secures the transfer of funds, by using a digital signature algorithm to prove ownership. Each block in the blockchain will have its own digital signature. We create a web page that contains the login and registration page. We create a key pair of each user that contains the private key and public key. Every time we check this blockchain is valid or not. The main reason for the paper is to research and focus on revealing and improving limitations of Blockchain from privacy and security perspectives. On the basis of this studying the blockchain we highly recommend the researchers to develop in the future.
