It is only a matter of time before technology emerges to open up a whole new world of opportunities. For example, the invention of the Internet was a development like this that changed the world in almost every theory. Blockchain technology is also one of the emerging technological advances that is expected to change the way transactions are conducted, thus affecting a wide range of potential applications. Blockchain is a distributed software network that works both as a digital logger and a method that allows secure transfer of assets without a mediator. Just as the Internet is a technology that facilitates the flow of digital information, blockchain is a technology that facilitates the digital exchange of digital value. Anything from coins to land titles to votes can be token, stored, and exchanged via a blockchain network.
Blockchain, the technology behind most cryptocurrencies that exist today, offers a paradigm shifting technology that has the potential to transform the way that we record and verify events on the Internet. By offering a decentralized, immutable, community verified record of transactions, regardless of what these transactions represent, blockchain technology promises to transform many industries. In this paper, we provide a survey of this very important technology and discuss its possible use-cases and its effect on society. The purpose of this paper is to familiarize the reader with the current state-of-the-art in the blockchain world both in terms of technology and social impact.

Blockchain is the Technology which allows assets to be transferred from one party to another simultaneously and without needing a third party, guaranteeing utmost security. In addition, it is a multiple global ledgers, shared by all people around the world, which enables them to do all kinds of transactions (Sutardja Center for Entrepreneurship & Technology Technical Report, 2015) in real time and without falling prey to fraud or manipulation. Besides, it is the biggest data bases, accessible to all people (BigchainDB, 2016) and containing verified assets which can be safely exchanged. Blockchain will have a huge effect on deferent levels, it will change the way all people adopt to deal through decades and threat traditional intermediary parties, on the other side it faces many obstacles stumbling blocks to be fully operated in different fields. This paper try to address the mechanism of blockchain technology, and how it works in simple words, then determine the possible applications of blockchain, and how to make best use of this technology, and finally the threats and challenges of blockchain. WHY BLOCKCHAIN IS A REVOLUTION? The blockchain system was first used in 2008 as the main platform for Bitcoin's virtual currency. Thanks to Blockchain, this cryptocurrency has won users' trust, so far at least. It is a common misconception that Bitcoin and Blockchain are one and the same; the truth is that the latter can be regarded as the backbone of the former, which distinguishes it from other digital currency systems (KAYE Scholar, 2018). It is worth mentioning that the Blockchain system can be used in many other applications. Traditional transactions and asset transfer usually involve mediators. These can be banks, necessary for money transfer, a ministry entitled to register transactions, a real estate publicity department to verify ownership, a real estate broker, etc. These intermediary entities are usually paid for their services. Blockchain provides an alternative where files are transferred, stored and managed with no need for such mediators. To be more accurate, the real mediator in this case would be millions of computers connected to the chain. The transaction moves from one computer to another in an encrypted form that guarantees safety, rules out the possibility of manipulation, forgery or fraud and secures registration priority rights. This poses a threat to millions of people around the world who would be more than likely to lose their jobs because of this system.

Blockchain technology is the key for decentralized society and gathered a lot of attention in recent times. The technology of Blockchain offers an infrastructure of secure network that allows the users to perform any operation without middleman. It is expected to bring a revolution due to its characteristics of being transparent, secure and scalable. Blockchain technology will bring the considerable efficiency gains, transparency, cost savings and fraud detection while allowing the data to be shared in real-time between multiple parties in a trusted and transparent manner. This chapter elaborately discusses the basic building blocks of Blockchain technology such as public key cryptography, Digital signature, Elements and types of Blockchain and its applications in different sectors. I. INTRODUCTION Blockchain is a chain of blocks in which the information of transactions is recorded and maintained in a distributed public ledger across a number of computers that are linked in a peer-to-peer network. Blockchain was first introduced by [1] who proposed a peer-to-peer payment system that allows cash transactions through the Internet without relying on the need for a financial institution. Blockchain is secure by design, and an example of a system with a high byzantine failure tolerance [2]. Bitcoin is the first application of the Blockchain concept to create a currency that could be exchanged over the internet using cryptography to secure the transactions. Bitcoin blockchain is the mother of all blockchain. Blockchain is an ordered data structure that contains blocks of transactions. Each block in the blockchain is linked to the previous block in the chain. The first block in the chain is referred to as the Genesis block. Each block created gets layered on top of the previous block to form a stack called a Blockchain. There are a set of rules for confirmation of the legitimacy of a block and to verify that block has not been altered maliciously. Blockchain technology solved the problem of Double-spending (the event where customer can spend a set of the same bitcoins in two different transactions) as the second transaction would be recognized as invalid.

Blockchain is a decentralized technology. When it comes to resolving business issues, it wields considerable power. Every transaction on the blockchain is encrypted, and each transaction is linked to a previous transaction or record. Blockchain transactions are validated by algorithms running on nodes. A single entity cannot start a transaction. Eventually, blockchain provides transparency by allowing any participant to view transactions at any moment. Smart contracts provide secure transactions, minimizing the risk of third-party interruptions. Ethereum is a decentralized platform based on smart contracts. It enables developers to create markets that transfer money according to the instructions given years ago. Blockchain is distinguished by two key characteristics: immutability and decentralization. Deals are completed faster; Transactions and authentication are completed in a matter of seconds, and much more.
