“…Nowadays it is possible to find plenty of material to understand the underlying principles on which DLTs are built: relevant reviews on the functioning principles of the Blockchain have been presented in [11], [12] and [13], while a thorough exposition on a more recent architecture for DLTs, called the Tangle, can be found in [9] and [14]. In [15] the authors discuss the advantages and disadvantages of Blockchain taking the insurance sector as an example. Unlike much of the literature on the topic, this paper proposes a critical perspective, emphasizing that the Blockchain should not be considered as a one-trick tool to be applied to every possible domain but, rather, a new technological advancement with its own niche of use.…”

“…The only change from before is that at each time T a when a new transaction is created, the type of the transaction is selected using the distribution (10). The variables can then be updated at times {T a , T a + h} according to the formulas (12)(13)(14)(15).…”

“…In order to gain some understanding of the system (12)(13)(14)(15) we consider the asymptotic regime of large arrival rate, where the time between consecutive transactions is very small. In this regime it should be reasonable to approximate the system (12)(13)(14)(15)) by a fluid model. The following derivation of the fluid model is heuristic, and it should be considered as an independent model for the Tangle which is motivated by the stochastic model described in the previous sections.…”

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...

The selection of the suitable blockchain software ecosystem has become very complex, given the growing market. More and more products with different functionality (mainly consensus algorithms and smart contracts) are available on the market. To identify the correct blockchain system for the respective application, a catalog of criteria with a focus on software quality is developed in this work. This catalog supports the selection of the right application and can be individually weighted. Methodology and BackgroundThis work has been developed using grounded theory and literature review methods. In order to determine the various criteria, a literature review was first carried out in order to capture the essential aspects within the scope of the software quality criteria. These works were then prioritized. The prioritization was

“…Establishing the required infrastructure for a blockchain based MaaS to be introduced is a key weakness, not only due to the capital needs, but also due to the technological requirements of such an initiative. Conducting small scale trials in the short-term, particularly in the tourism and hospitality sectors, could be an option to build critical mass locally and address fundamental blockchain disadvantages [36]. • Data protection and data management compliance at local, national and international levels are naturally an immediate threat.…”

In this paper two contemporary technological novelties are combined to introduce the concept of a blockchain-based MaaS, with the aim of pinpointing where and how business value can be created through data-based services of such a system. Towards this purpose, an integrated version of the Business Model Canvas is deployed, combining the advantages of the Lean Canvas and the Ethics Canvas. The overview of data flows among the versatile system stakeholders are outlined to highlight the potential benefits for diverse industries through sharing and collaboration.
