In this chapter, the authors have detailed the need of blockchain technology along with its case studies in different domains. The literature survey is described that describes how blockchain technology is rising. Further, a number of domains where blockchain technology can be applied along with its case studies have been discussed. In addition, the authors have considered the various use cases with their recent issues and how these issues can be resolved using the blockchain technology by proposing some new ideas. A proposed security framework in certain applications using blockchain technology is presented. Finally, the chapter is concluded with future directions.

Blockchains have pulled in overall consideration lately and is characterized as an immutable, successive chain of records called blocks. The record contains transactions, documents or some other information, and are fastened together utilizing hashes. It is executed and overseen by a peer-to-peer network (Christin, N., 2011; Iansiti, M., & Lakhani, K. R., 2017; Swan, M., 2015; Cachin, C., 2016) of computers (also called peer nodes) spread everywhere throughout the globe. Blockchain likewise called distributed ledger which utilizes independent PCs (nodes) to record, share and synchronize transactions in their particular electronic ledgers, rather than keeping information incorporated on a server as in a customary record (Nandwani, K., 2018). A Schematic outline of the blockchain is depicted in Figure 1. Blockchains have the potential to disrupt any industry that employs the use of a trusted middleman and gives direct control back to the end-user. In any case, similarly, as with any technological revolution and the paradigm shift that joins it is a procedure of trial and error. What works and what does not and we are as of now in that stage with blockchain advancements. 99% of the business sectors are filled by an unadulterated hypothesis (Peters, M. A., 2017). There are no completely useful blockchain items that can oblige the requests of the majority. Blockchains must be less expensive, snappier, simpler to utilize and similarly as versatile, if not more thus, than the present frameworks set up. The coming of the web drove the technological revolution of the 90's and the industrial upheaval was in the late eighteenth century (Peters, M. A., 2017). These quantum jumps in human capacity and accomplishment change our whole reality and disturb pretty much every settled industry. They change the manner in which we travel, cooperate, communicate, business with one another. All that we once knew is flipped on its head and life gets improved, making things a lot less demanding and progressively productive. The same is the appearance of blockchain technology where the component of trust is the whole sudden put under the control of target numbers and PCs.

Blockchain is the initial step at placing trust into PCs. It sounds kind of terrifying where it would state that however, the seasons of Skynet and eliminators are far away and except if we create methods for keeping self-aware robots from turning into a reality, at that point we ought to be safe. Blockchain technology is still without a doubt so in its earliest stages. Blockchains are moderate, user-unfriendly, unscalable, and costly. For instance, DApps created on ethereum require the end-user to initially buy ethereum and afterward pay a transaction fee each time they accomplish something in the DApp. Then again, EOS expects developers to buy over the top expensive RAM to build up a DApp while the users get transaction fees, simply after the user gets some EOS, downloads an EOS wallet from Github, make a key pair and sends EOS to that key pair. Not to speak to the average consumer who could think less about decentralization. The fact of the matter is that blockchain technology needs to develop before mainstream adoption happens. A blockchain that takes care of enormous real-world problems, finds a harmony among decentralization and administration while giving speed, scalability, cost viability, and overall smooth user experience will be the blockchain that ascents above them all. 2018 was an incredibly dynamic year for blockchain and cryptocurrencies (Houben, R., & Snyers, A., 2018). Numerous jumps in advancement were made and blockchain is entering the worldwide awareness increasingly every day. The subject of mass selection is when, not in the event that it occurs. We unquestionably observe this occurrence very soon, however as things remain at the present minute, the blockchain space still makes them develop agonies to traverse.
