ORGANIZATIONS ARE ALREADY USING BLOCKCHAIN TECHNOLOGY TO DECENTRALIZE Organizations such as corporations, clubs, and even governments form because societies need to, among other things, make collective decisions. 16 These organizations allow people with different views to reach a consensus, respond to the needs of the day, and to plan for the future. 17Blockchain computing changes how consensus can be reached, and will therefore change how any organization that can apply blockchain technology serves the members of that organization. 18 Currently, in most organizations "decision-making is concentrated at the 12 See, e.g., Chris Hammerschmidt, Consensus in Blockchains.In Short, MEDIUM (Jan.27, 2017), https://medium.com/@chrshmmmr/consensus-in-blockchain-systems-in-short-691fc7d1fefe(explaining how once an individual or entity adds information to a blockchain, "distributed operators of blockchain" have to agree before those people are added to the blockchain).13 See Curtis Miles, Blockchain security: What keeps your transaction data safe?, IBM (Dec.12, 2017), https://www.ibm.com/blogs/blockchain/2017/12/blockchain-security-what-keeps-your-transaction-data-safe/(requiring "massive amounts of computing power to access every instance (or at least 51 percent majority) of a certain blockchain and alter them all at the same time," in order to alter the blockchain).14 See Preethi Kasireddy, ELI5: What do we mean by "blockchains are trustless"?, MEDIUM (Feb.3, 2018), https://medium.com/@preethikasireddy/eli5-what-do-we-mean-by-blockchains-are-trustless-aa420635d5f6(explaining how blockchains "minimize the amount of trust required from any single actor in the system . . .by distributing trust among different actors in the system."). 15See generally, Konstantinos Christidis & Michael Devetsikiotis, Blockchains and Smart Contracts for the Internet of Things, IEEE ACCESS J. 2292, 2292 (June 3, 2016), http://ieeexplore.ieee.org/document/7467408/("[B]lockchains have recently attracted the interest of stakeholders across a wide span of industries."). 16See, e.g., Blockchain Is Pumping New Life into Old-School Companies Like IBM and Visa, FORTUNE (Dec.26

Blockchain technology disrupts existing business models and practices in different sectors of the economy. It has the potential to revolutionize the way we do business, and it can be combined with other technologies like Internet of Things (IoT) or Artificial Intelligence (AI) to increase its disruptive effect. In this paper we study the impact of the implementation of a blockchain solution in the area of solar energy. The results of this research demonstrate that blockchain technology can disrupt the energy sector in various ways including, among others, disruption in process, product, position and paradigm, and platform innovation.

The public sector presents several promising applications for blockchain technology. Global organizations and innovative ministries in countries such as Dubai, Sweden, Finland, the Netherlands, and Germany have recognized these potentials and have initiated projects to evaluate the adoption of blockchain technology. As these projects can have a far-reaching impact on crucial government services and processes, they should involve a particularly thorough evaluation. In this paper, we provide insights into the development of a framework to support such an evaluation for the German asylum process. We built this framework evolutionarily together with the Federal Office for Migration and Refugees. Its final version consists of three levels and eighteen categories of evaluation criteria across the technical, functional and legal domains and allows specifying use-case specific key performance indicators or knockout criteria.

The development of Energy-Internet is currently suffering from a series of issues, such as the conflicts among high capital requirement, low-cost, high efficiency, the spreading gap between capital demand and supply, as well as the lagged trading & valuation mechanism, any of which would hinder Energy-Internet's evolution. However, with the development of Blockchain and big-data technology, it is possible to work out solutions for these issues. Based on current situation of Energy-Internet and its requirements for future progress, this paper demonstrates the validity of employing blockchain technology to solve the problems encountered by Energy-Internet during its development. It proposes applying the blockchain and big-data technologies to pricing and trading energy products through Energy-Internet and to accomplish cyber-based energy or power's transformation from physic products to financial assets.

Since the beginning of crypto currency in 2008, blockchain technology rise as progressive technology. Despite the fact that blockchain began off as a core technology of Bitcoin, its utilization cases are growing to numerous fields such as, security of Internet of Things (IoT), banking sector, industries and medical etc. In recent years IoT has gained popularity due to its usage in smart homes and smart city projects around the world. Unfortunately, IoT devices possess limited computing power, low storage capability and network capacity therefore they are more prone to attacks than other endpoint devices such as cell phones, tablets, or PCs. This paper focus on significant security issues for IoT, security prerequisites for IoT alongside the current attacks and maps IoT security issues against existing solutions found in the literature. Blockchain technology can be a key empowering influence to take care of numerous IoT security issues. Finally describe the future work directions.

The convergence of the physical and virtual worlds radically challenges our legal, economic and other institutional regimes. In contrast, property rights and transaction cost regimes are still largely based on the pre-digital era. The blockchain architecture seems to offer a way for one Internet user to safely and securely transfer a unique piece of digital property to another in such a way that anyone knows that the transfer has taken place and no one can challenge the legitimacy of the transfer. Subsequently, transaction costs could diminish and property rights be unbundled and partially enforced on an unprecedented granular level. This paper explores the implications of blockchain technology for our established property rights and transaction cost regimes. It aims to discuss whether the established regimes and theories will prevail or will need to adapt to the advent of blockchain technology.

Blockchain is a new, foundational technology with a vast amount of application possibilities. However, practitioners might not be aware of which use cases in their own business model might benefit from blockchain technology. To aid them in analyzing their business regarding blockchain suitability, this paper introduces a use case identification framework for blockchain and a use case canvas. In the development process they have been evaluated with internal and external reviews in order to offer the best possible guidance. In combination they offer an analysis framework to help practitioners decide which use cases they should take into account for blockchain technology, which characteristics these blockchain implementations would have, and which specific advantages they would offer.

One of the most tone-deaf suggestions in the Brexit proceedings so far came in August 2017, when the UK Brexit team released a long-awaited position paper setting out its proposal on how to manage its border with Ireland. It suggested that "technology-based solutions" - meaning blockchain, the technology behind cryptocurrencies such as Bitcoin - could be implemented to "make it easier to comply with customs procedures." The UK's vague and misguided solution was quickly ridiculed by experts at home, as well as seasoned counterparts abroad. Although blockchain technology has now been around for ten years, it has not seen any meaningful implementation in global supply-chains, let alone within customs offices. Indeed, a "seamless and frictionless" border in compliance with fundamental customs procedures - itself a unicorn - cannot simply be coded into existence on its own. In reality, questions of capacity and time constraints mean that technological solutions are actually unworkable ...

“In the future, virtually every function in the world of financial services will be displaced, disintermediated and decentralized. The Internet gave us a powerful way to share and access information. Blockchain now gives us a powerful way to share and access value.” During a February 2017 AICPA roundtable, Chairman of the Wall Street Blockchain Alliance and previous Global Head of Trading Analytics at Thomson Reuters, Ron Quarantana spoke to the revolutionary scale of blockchain. Quaranta, viewed by many as an expert in financial technology, predicts that the adoption of blockchain, both by the Big Four accounting firms and their clients, will disrupt the accounting industry by greatly reducing the time and skill needed to perform a quality audit. Some, such as Thomson Reuters’ Jon Baron, even claim that blockchain may eliminate the need for financial statement audits altogether. To many, blockchain is synonymous with Bitcoin, the cryptocurrency that, over the past three years, has returned 3,310%, compared to 35% and 36% returns of the S&P 500 and Dow Jones Industrial Average (DJIA), respectively. Blockchain, however, is much more than Bitcoin, with applications stretching further than cryptocurrency. Rather, it is a peer-to-peer hosted public ledger that does not require a central authority to support or verify transactions, and is unalterable in future periods. In this study, I propose to examine what blockchain technology means for the 887,000 people currently employed by the Big Four. More specifically, I seek to expand upon whether the potential adoption of blockchain in the coming years will reduce audit fees, impact audit quality, or perhaps do away with the audit completely.

Abstract. We evaluated the feasibility of using a blockchain technology to create a traceability solution for pharmaceutical drugs that would promote compliance with recent legislation. Counterfeit and other illegitimate pharmaceutical drugs threaten patient safety, drug efficacy, and patient trust. The purpose of the Drug Supply Chain Security Act (DSCSA) is to greatly reduce distribution of illegitimate drugs by requiring all pharmaceuticals to be serialized and traceable from the manufacturer through the supply chain to the dispenser. A software application to serialize and track pharmaceuticals must overcome numerous obstacles. In particular, the solution must provide a high degree of trust while also protecting privacy for manufacturers, distributors, and patients. This research will propose that a blockchain-enabled application will solve for many of the most challenging needs for this solution.
