This paper describes how Distributed Ledger Technologies can be used to enforce social contracts and to orchestrate the behaviour of agents trying to access a shared resource. The first part of the paper analyses the advantages and disadvantages of using Distributed Ledger Technologies architectures to implement certain control systems in an Internet of Things (IoT) setting, and then focuses on a specific type of DLT based on a Directed Acyclic Graph. In this setting we propose a set of delay differential equations to describe the dynamical behaviour of the Tangle, an IoTinspired Directed Acyclic Graph designed for the cryptocurrency IOTA. The second part proposes an application of Distributed Ledger Technologies as a mechanism for dynamic deposit pricing, wherein the deposit of digital currency is used to orchestrate access to a network of shared resources. The pricing signal is used as a mechanism to enforce the desired level of compliance according to a predetermined set of rules. After presenting an illustrative example, we analyze the control system and provide sufficient conditions for the stability of the network. I. INTRODUCTORY REMARKSBitcoin, and the technology that underpins it, Blockchain, have recently become a source of great debate and controversy in both business and scientific communities. To its supporters, Distributed Ledger Technology (DLT) (the agnostic term for Blockchain and related technologies)[1][2] is a key technology that will unlock new disruptive business models such as peer to peer trading, protect the rights of individuals, democratise society, and remove the need for central arbiters in many applications (the greedy middle that manages and exploits our assets and identities for financial reward). To its detractors, DLT is nothing more than pure hype, irrational speculation, and a means to enable new forms of illegality built on the anonymity that underpins the technology. DLT as a technology is truly unparalleled in its ability to split and divide opinions. Countries such as Switzerland and Singapore are openly embracing its potential, while other countries, such as China and India are trying to regulate its use [3]. Leading societal thinkers are also split on DLT; with George Soros 1 thinking it to be nothing more than a bubble and others such as Al Gore embracing the idea that algorithms might one day assume some of the functions of government 2 . A first version of this manuscript is posted to the Arxiv, arXiv:1807.00649 1 https://www.forbes.com/sites/gurufocus/2018/01/25/george-soros-fromdavos-bitcoin-is-a-typical-bubble/#7a1d097929d0 2 https://www.forbes.com/sites/ksamani/2017/10/04/how-crypto-willreshape-capitalism-as-we-know-it/2/#5b9daa0e6ed4 Though the schism in DLT thinking is very real, everyone seems to agree on one basic fact -that DLT is potentially a very disruptive technology. Even opponents of the technology are exploring the many ways it can be used, and the consequent potential implications for society. Roughly speaking, as the name suggests, DLT is a technology...

“…Incorporating blockchains into health-care networks can potentially overcome the challenges in privacy preservation and security assurance of health-care data. For example, the work of [88] shows that using blockchain technology can protect health-care data stored in cloud servers. Meanwhile, Griggs et al [89] developed a blockchain-based system to assure the private health-care data management.…”

Internet of Things (IoT) is reshaping the incumbent industry to smart industry featured with data-driven decisionmaking. However, intrinsic features of IoT result in a number of challenges such as decentralization, poor interoperability, privacy and security vulnerabilities. Blockchain technology brings the opportunities in addressing the challenges of IoT. In this paper, we investigate the integration of blockchain technology with IoT. We name such synthesis of blockchain and IoT as Blockchain of Things (BCoT). This paper presents an in-depth survey of BCoT and discusses the insights of this new paradigm. In particular, we first briefly introduce IoT and discuss the challenges of IoT. Then we give an overview of blockchain technology. We next concentrate on introducing the convergence of blockchain and IoT and presenting the proposal of BCoT architecture. We further discuss the issues about using blockchain for 5G beyond in IoT as well as industrial applications of BCoT. Finally, we outline the open research directions in this promising area.

“…However, with the current advancement in healthcare technology, these approaches are not just sufficient because the patient has been exploited by various stakeholders through different means and without their consent [11], [12]. In this context, researchers are keen to find various secure solutions based on blockchain based healthcare approaches [13].…”

The healthcare industry is constantly reforming and adopting new shapes with respect to the technological evolutions and transitions. One of the crucial requirements in the current smart healthcare systems is the protection of patients sensitive data against the potential adversaries. Therefore, it is vital to have secure data access mechanisms that can ensure only authorized entities can access the patients medical information. Hence, this paper considers blockchain technology as a distributed approach protect the data in healthcare systems. This research proposes a blockchain based secure and efficient data accessibility mechanism for the patient and the doctor in a given healthcare system. Proposed system able to protect the privacy of the patients as well. The security analysis of our scheme shows that it can resist to well-known attacks along with maintaining the integrity of the system. Moreover, an Ethereum based implementation has used to verify the feasibility of our proposed system.
