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.

In this research paper the researcher given the analysis report of blockchain technology and its significant usage in new era of digital economy. The researcher stated that block chain technology is a network software protocols that enables the secure transfer of money, assets, and information via the internet, without need a third party intermediary. The researcher focused on some of the significant research issues and new dimension of centralized data centers, distributed ledger technology, specific times tamped with a unique cryptographic signature, tamper-proof auditable history of all transactions. In current scenario the block chain technology provides highly secure data in all aspects using cryptography, fingerprint that verifies the authenticity of the data. Alteration of the original data causes the hash of the altered data to no longer match the original fingerprint. Transactions on the blockchain are grouped and stored in blocks. The combined hash of these transactions is also stored, and each subsequent block saves the combined hash of the previous block. The resulting digital applications are digital asset registries, blockchains as leapfrog technology for global financial inclusion, long-tail personalized economic services, and net settlement payment secure channels which provides a new era of digital economy. In this research article the researcher focused on some of the significant research issues and challenges, statistical report of current blockchain technology usage and future direction for highly secure technology of new era of digital economy.

This article describes how Blockchain is a technology that has a great potential to change the way business is done in the future, exactly like the internet did in the early nineties. Blockchain offers new opportunities to develop new types of digital services to overcome business problems, and improve business practices by making transaction information a public resource. While research on the topic is still emerging, it has mostly focused on crypto-currencies instead of taking advantage of this novel concept to create new advanced services. This article discusses blockchain and the technology behind it, some of its possible applications, as well as threats targeting the new poorly understood technology.

The blockchain is generally defined as publicly disclosed and linked ledger of online transactions that are performed in peer to peer network. Also, all the transactions executed in this public ledger are verified by the majority of the participants. Blockchain has brought a different approach to the data sharing and management. It has come up with the solutions to a number of problems that the digital world has been facing since long. Blockchain technology is highly efficient to transform a number of industries such as financial and non-financial ones. This paper explores the blockchain technology as a thing like an internet i.e. the future of Internet and explains it's numerous scopes in different sectors for both the personal and professional purposes. But firstly, we will come across the basics of this technology, how did it come into existence and what's its current status. We will also study what can be the positive and negative impacts of using blockchain technology. And at last, we will explain the challenges along with the opportunities this latest technology brings in the digital world.

Information tracking refers to the practice of tracking web users (and mobile apps users) on the Internet platform, browsing histories, website visitors, trailing email, etc. Thus, blockchain is defined as a distributed database that maintains a shared list of records. The records are in the form of encrypted form, and each encrypted block of code contains the history of every block that came before it with time stamped transaction data down to the second. The chaining those blocks together is called blockchain. Therefore, blockchain technology is defined as a decentralized and distributed digital ledger that is used to record transactions across many computers so that the record cannot be altered retroactively without the alteration of all subsequent blocks and the collusion of the network. Stuart Haber and W. Scott Stornetta described the first work on a cryptographically secured chain of blocks in 1991. The term blockchain 2.0 is an applications of the distributed blockchain database, emerged in 2014. Abstract The Internet today uses a new technology called the blockchain, which is based on decentralization communication systems. The blockchain thus leads to the creation of potential system, where we can store data and manage information. This will reduce the role for one of the most important regulatory actors in our society, i.e., middleman. Blockchain technology evolves by the creation of decentralized currencies. It creates self-executing digital contracts (smart contracts) and intelligent assets, which can have control over the Internet (smart property). Thus, blockchain is considered to be decentralized (autonomous) invention that works with more democratic or participatory decision-making organizations, which operate over a network of computers without any human intervention. This technology can be adopted to any application in the fields of business, finance, networking and law. The study makes three contributions to theory and practice on blockchain. Firstly, the research clarifies the strategic understanding of blockchain technology by presenting a framework for use in case evaluation and opening the opportunity offered by blockchain to increase trust or negate the need for it in a transaction. Secondly, it presents the assessment of risk by dealing with blockchain transaction and creates a blueprint of security measures towards hybrid framework. Thirdly, it reveals the potential risks and risk-mitigation actions. Finally, it presents list of important applications, bearing the trust in mind the most recent developments.
