We are living in a rapidly progressing world where technology is developing and progressing every single day. We have shifted from analog world to digital world as digital world leads to automation, efficiencies, speed and opportunities. With the increase in technologies, the need for security and the challenge on level of security of data also increased. So security of the system plays a vital role in development of digital world. A robust framework is desired on the prevention of the security breaches. We need processes which are more transparent, secure and efficient. A new technology came into existence named as “BLOCKCHAIN TECHNOLOGY” which have transformed the digital world into a more efficient and flexible world with high level of security. Blockchain is an open, distributed, decentralized, public ledger technology which enables us to maintain a permanent and tamper-proof record of transactional data where multiple authoritative domains who do not trust each other to cooperate, coordinate and collaborate in decision making process. In this paper we will look at the Blockchain Technology and focused exclusively on aspects of the technological infrastructure such as security, anonymity, scalability or the flexibility of consensus mechanisms. We will provide an overview on recent developments, feasibility and benefits of the Blockchain technology. The objective is to have an insight on the basic concept of Blockchain technology and the types of Blockchain technology we have and its uses in different fields.
