Every industrial sector has started analysing the ways of utilizing the advancements in cyber physical technologies in their operations. Internet of Things has emerged as a new way of connecting the physical world to the cyber world to obtain tremendous amount of information about the physical world and make it available in the Internet for advanced analytics and business decision making. Thus, IoT promises huge results in terms of revenue, safety, monitoring and management in every business unit of an Enterprise. Block chain has emerged as a key technology in storing data in distributed ledgers which is not possible or extremely difficult to modify or damage. Wherever data security is significant and ensuring the integrity of data is challenging, we may apply Block chain to resolve the issues. This paper analyses the suitability of using Block chain in IoT ecosystems in the first part. The consequences of integrating Block chain with IoT and the opportunities and challenges in this process are discussed in the next part of the paper with use cases. Based on the contemporary challenges and maturity of the technology, this paper concludes the most appropriate set of applications on which Block chain and IoT can function together and it proposes a way of making the best possible outcomes from both the domains.

Emergency medical services universally get regarded as the essential part of the health care delivery system [1]. A relationship exists between the emergency patient death rate and factors such as the failure to access a patient's critical data and the time it takes to arrive at hospitals. Nearly thirty million Americans do not live within an hour of trauma care, so this poor access to trauma centers links to higher pre-hospital death rates in more than half of the United States [2]. So, we need to address the problem. In a patient care-cycle, loads of medical data items are born in different healthcare settings using a disparate system of records during patient visits. The ability for medical care providers to access a patient's complete picture of emergency-relevant medical data is critical and can significantly reduce the annual mortality rate. Today, the problem exists with a continuous recording system of the patient data between healthcare providers. In this paper, we've introduced a combination of secure file transfer methods/tools and blockchain technology as a solution to record patient Emergency relevant medical data as patient walk through from one clinic/medical facility to another, creating a continuous footprint of patient as a secure and scalable data source. So, ambulance crews can access and use it to provide high quality pre-hospital care. All concerns of medical record sharing and accessing like authentication, privacy, security, scalability and audibility, confidentiality has been considered in this approach.

Blockchain technology is a highly popular yet highly misunderstood concept that is used today and in future applications. To enhance security and privacy, many applications adopt Blockchain. However, there are intrinsic drawbacks and emerging challenges. In this paper, we study popular security applications in Blockchain, present their major problems, as well as other challenges in Blockchain which allows future research to be conducted more efficiently.

The feedback control loop is the atomic unit in a control system. Typically, feedback control loops are rigid objects that involve a dynamical system, or plant, which has a set of its output states measured by dedicated sensors, which in turn feed a processing unit, known as controller, that calculates actions to be applied as inputs to the plant, via elements known as actuators, in order to drive the outputs to a desired value or trajectory. The appearance of the Internet of Things (IoT) paradigm, where a large number of sensors and processing units interact over a communication network, offers an underlying infrastructure to operate and configure control loops using a different logic: an on-demand strategy. This work introduces the concept of on-demand control loop, and proposes the use of blockchain technology as the enabling infrastructure for generating on-demand control loops over large-scale IoT environments. General design guidelines are given and a simple implementation example over the Ethereum blockchain is presented, which shows the feasibility of the proposed technique.

The main attraction of cryptocurrency is the decentralized, append-only public ledger blockchain that records the transactions. The current challenge of bitcoin blockchain is to increase the throughput. Two-party or multi-party payment channel using multi-signature address formed a connected payment network to solve the issue of scaling that fascinated bitcoin community. The micropayment channel solution implicitly assumes that parties will continue to interact for long intervals. This assumes a long-lived relation between buyer and seller. Another major disadvantage of forcing participants to lock funds for long intervals. The micropayment channel must know about the parties beforehand.We address this issue and present a protocol that offers freedom to do micropayment transaction with anyone as per the need without any prior knowledge about the parties. The protocol gives an alternate secured path for zero-confirmation transactions. From the test cases, we have shown that buyer will get quick services from sellers and honest sellers will not lose their funds share.

The ultimate aim of a smart city is to enhance the quality of life for its residents and businesses through modern technologies in order to reduce resource deterioration and maintain overall costs. From this perspective, blockchain is one of these technologies that has received much attention during the recent years as it offers new alternatives for individuals and institutions in the smart city context. This study aims to explore the potential and contribution of blockchain in smart cities by studying and reviewing the literature of scientific research on the concept and fundamentals of blockchain, involving its most practical applications. In addition, it summarizes worldwide examples of success in using blockchain as well as exploring the challenges and opportunities related to this technology in smart cities. Thus, this study provides a useful reference for researchers to review all about the new blockchain technology.

A centralized IoT network has a problem of data centralization because data is stored in a center. A blockchain is emerging as a solution to solve the problem in the IoT network by storing blocks to each device. However, lightweight IoT devices cannot store all of the blockchain due to their low storage capacity. We propose storage compression consensus (SCC) algorithm which compresses a blockchain in each device to ensure the storage capacity. When a lightweight device does not have enough storage space, the device processes the SCC to compress the blockchain. We implemented simulations to compare between the SCC and the existing consensus algorithm. As a result, the proposed SCC reduced the storage capacity of stored blockchain by 63% compared to the existing algorithm.

Blockchain technology is one of the most widely acclaimed technologies of recent years. It enables the creation of distributed applications involving multiple actors or organizations in which transactions and data are not under the control of a central authority. Transactions are stored in a distributed public ledger in an immutable format in such a way that they can be verified by participants. This disintermediation promises to remove much of the “friction” (and lower costs) from distributed transactions by cutting out the intermediary party, thus enabling a variety of applications in finance, government, health, etc. This paper provides an overview of recent research in the application of blockchain technology to higher education for those who are interested in working in this area or just understanding how higher education may be positively impacted in the future by blockchain.
