This work is the culmination of all my adventures in these last two years, which are ironically unrelated to academics, but are of friendship, self-love, and perseverance even in the midst of a world that literally seemed to be falling apart — , you are a wonder. To my mom, who has supported me throughout everything: you and dad have been pliant bows to this living arrow. To my weird sisters: I have never come across such odd rocks; I hope you know how much you mean to me.

To my big brother, who I will always look up to: looky! I made a thingy! To my companions throughout these years in Sophia: non sarei soppravvissuta senza di voi, sarete sempre le mie sorelle. To Loppiano, the Filipino community, and all those who have given me light even through the briefest of encounters: each of you will forever be etched on my soul.

To Sophia, and the exemplary professors who have given us so much more than just lessons in the classroom: you have inspired me and influenced me deeply as a person, and as a citizen of the world. To my supervisor and co-supervisors, thank you for the guidance and the freedom you have allowed me, with which I was able to write a thesis that I can be proud of.

To God be the glory. For the year , it revealed that trust has changed profoundly, and noted that although there is a divergence of trust in other aspects, the world is united on one front — all share an urgent desire for change. Only one in five feels that the system is working for them, with nearly half of the mass population believing that the system is failing them Edelman, Studies attribute this loss of trust to the Global Financial Crisis of , as its aftermath exposed systemic flaws that brought the world economic order to the brink of collapse Edelman, ; Nandwani, The study further reveals that for the year , despite it being in an era of strong global economy and near full employment within the surveyed countries, none of the four societal institutions that the study measures are trusted Edelman, Concurrently, technology continues to alter human behaviors and instincts, pushing institutions to keep up with changing customer expectations while simultaneously developing the technologies of the future Marshall, According to Rachel Botsman , these changes are indicative of a new phase in the evolution of trust.

The dwindling of trust in institutional power is accompanied by an emergence of a new kind of trust that moves power away from a single source and shares that responsibility across a wide range of sources. With the Global Financial Crisis as foreground, a white paper introducing Bitcoin was published in by a person or a group called Satoshi Nakamoto. It described the concept of a cryptocurrency implemented on top of a blockchain, which could provide an alternative way to build trust, record truth, secure transactions and create a decentralized network spanning the globe outside the purview of any authority Nandwani, Riding the wave of distributed trust, the blockchain has been cause for much excitement since its very nature allows the empowering of communities over central authorities.

The potential impact of the underlying technology, much more than that of the cryptocurrency, is often compared to the impact of the Internet, which now pervades our everyday life Arun et al.

Academic Kevin Werbach contends that it is a new kind of trust altogether, while security technologist Bruce Schneier argues that there is no good reason to trust blockchain at all. This research is an exploratory one, given that blockchain is a relatively new technology and that most case studies are still in their infancy, save the earlier blockchains such as Bitcoin and Ethereum.

The study employs a secondary research method, consisting largely of online and literature research. Case study research on the DAO hack has also proved useful in determining the limitations and areas for improvement of the technology. Primarily, the objective of the study is to examine the hypothesis that blockchain is indeed a technology that can pervade the world of finance, economics and other sectors as a new architecture of trust.

To understand the correlation between trust and blockchain, a deconstruction of some of our existing social and philosophical constructs is required, such as how we trust each other and how we arrive at the truth and then record it Nandwani, Thusly, the first chapter discusses the general definition of trust, how trust is built, how trust is broken, the rise of distributed trust, and the various architectures of trust that have developed over history.

Theoretically, this chapter aims to describe the societal foundations on which the blockchain is set. This section discusses the core concepts of blockchain, such as hashing, consensus algorithms, distributed ledger technology, and smart contracts.

The Blockchain Trilemma, on the other hand, describes the ongoing attempt of developers to solve the equilibrium between decentralization, security and scalability. Chapter 3 presents the findings about blockchain trust, structured into four paradoxes: decentralized yet centralized, immutable yet changeable, transparent yet highly encrypted, algorithmic yet human.

It aims to adequately describe the various benefits, implications and limitations of each element that are inherent in a blockchain — the very features that make blockchain unique. The chapter then ends with some notable applications of blockchain in the social sector, demonstrating the possibilities that blockchain has in store for us.

Trust is an elusive concept. Despite its pervasiveness in the decisions we make on a daily basis, its definition has been a subject of discussion among philosophers for centuries.

Trust is fundamental to almost every action, relationship and transaction Werbach, Communities would definitely not exist without it, and so it makes human society itself possible Luhman, It enables small and large acts of cooperation that all add up to increased economic efficiency Botsman, Virtually every commercial transaction has within itself an element of trust, certainly any transaction conducted over a period of time Arrow, In this sense, it is the oil that lubricates social and business transactions, and the factor that renders the boundless complexity of the modern world tractable Werbach, Defining trust How do we define trust?

Trust is not binary — one need not be categorized as either perfectly trusting or purely untrusting Cross, Fukuyama differentiates high-trust and low-trust societies.

For many, trust is about confidently relying on another person. The more we interact with a person over time, the more confident we become about how they will behave. Trust can therefore be viewed on a spectrum along multiple dimensions.

Types of trust Among the various taxonomies of trust, it can be broken down into two basic theoretical types: cognitive trust and affective trust. Although these two concepts are not perfectly discrete, they can serve as tools in analyzing and understanding the concept of trust. Cognitive trust A simplistic definition of trust is cognitive risk assessment: is it reasonable to rely on this person or organization? In its strictest form, it is based upon a cost-benefit analysis of the benefits of trust versus the associated risks Cross, In a business context, it is necessary for any large entity to trust upon agents to perform transactions in order for the entity to gain the benefit of new business.

On a more personal level, a mother gains free time from trusting a babysitter to watch her child. There is, of course, a running risk in both cases. Cognitive trust requires an assessment of the probability and the magnitude of that risk of harm Cross, The cognitive assessment of trust is also affected by the facility and effectiveness of monitoring the party to be trusted.

In assessing the relative risk of trusting, the ex-ante risks are often part of the equation as well, such as the reputation or past experiences or recommendations. Post facto remedies are also incorporated in the assessment of this risk. Another example can be found in e-marketing, wherein the customer is asked to give the number of his credit card to the marketer on a platform such as Amazon or other online retailers.

Taking everything into account, a cognitive assessment of the user would arrive at the conclusion that the credit card number would not likely be abused Cross, Affective trust While the cognitive dimension is important, it cannot represent the entirety of trust. Otherwise, trust would be nothing more than rational reliance.

Blockchain technology is perhaps the most talked about and yet the most misunderstood emerging technology in the world today. Since its inception, the secure, distributed ledger technology has widely been viewed through the lens of virtual currencies, particularly the hype surrounding the buying and trading of Bitcoin and other digital coin offerings. Indeed, surveys have shown that consumers are largely aware of what Bitcoin is , but do not know or understand about the blockchain technology that powers it. But those news stories have obscured the quiet blockchain revolution that has been taking hold at major corporations, among forward-thinking policymakers, and with startup technologists, who have been exploring how blockchain technology could make a wide variety of corporate and government operations more efficient and secure.

Today, blockchain tech has moved far beyond Bitcoin into practical and planned uses that are already changing the future of currency, transactions, contracts, capital raising, and other areas.

With the development of the Internet of Things IoT field, more and more data are generated by IoT devices and transferred over the network. However, a large amount of IoT data is sensitive, and the leakage of such data is a privacy breach. The security of sensitive IoT data is a big issue, as the data is shared over an insecure network channel. Current solutions include symmetric encryption and access controls to secure the data transfer, but they have some drawbacks such as a single point of failure. Blockchain is a promising distributed ledger technology that can prevent the malicious tampering of data, offering reliable data storage.

Effective date : Blockchain-based, smart contract platforms have great promise to remove trust and add transparency to distributed applications. However, this benefit often comes at the cost of greatly reduced privacy. Techniques for implementing a privacy-preserving smart contract is described. The system can keep accounts private while not losing functionality and with only a limited performance overhead. This is achieved by building a confidential and anonymous token on top of a cryptocurrency. Multiple complex applications can also be built using the smart contract system.
