The Limits Of Trust-free Systems: A Literature Review On Blockchain Technology And Trust In The Sharing Economy

The Limits Of Trust-free Systems: A Literature Review On Blockchain Technology And Trust In The Sharing Economy

The limits of trust-free systems: A literature review on blockchain technology and trust in the sharing economy Author links open overlay panel FlorianHawlitscheka Summary of literature on trust in the context of blockchain and the sharing economy. Conceptualizations of trust differ substantially between the contexts. Blockchain technology is to some degree able to replace trust in platform providers. The notion of trust-free systems depends on the development of trusted interfaces. At the tip of the hype cycle, trust-free systems based on blockchain technology promise to revolutionize interactions between peers that require high degrees of trust, usually facilitated by third party providers. Peer-to-peer platforms for resource sharing represent a frequently discussed field of application for trust-free blockchain technology. However, trust between peers plays a crucial and complex role in virtually all sharing economy interactions. In this article, we hence shed light on how these conflicting notions may be resolved and explore the potential of blockchain technology for dissolving the issue of trust in the sharing economy. By means of a dual literature review we find that 1) the conceptualization of trust differs substantially between the contexts of blockchain and the sharing economy, 2) blockchain technology is to some degree suitable to replace trust in platform providers, and that 3) trust-free systems are hardly transferable to sharing economy interactions and will crucially depend on the development of trusted interfaces for blockchain-based sharing economy ecosystems.

[1710.06372] Blockchain-based Smart Contracts: A Systematic Mapping Study

Computer Science > Cryptography and Security Title:Blockchain-based Smart Contracts: A Systematic Mapping Study Abstract: An appealing feature of blockchain technology is smart contracts. A smartcontract is executable code that runs on top of the blockchain to facilitate,execute and enforce an agreement between untrusted parties without theinvolvement of a trusted third party. In this paper, we conduct a systematicmapping study to collect all research that is relevant to smart contracts froma technical perspective. The aim of doing so is to identify current researchtopics and open challenges for future studies in smart contract research. Weextract 24 papers from different scientific databases. The results show thatabout two thirds of the papers focus on identifying and tackling smart contractissues. Four key issues are identified, namely, codifying, security, privacyand performance issues. The rest of the papers focuses on smart contractapplications or other smart contract related topics. Research gaps that need tobe addressed in future studies are provided. Continue reading >>

Blockchain Protocols In Clinical Trials: Transparency And Traceability Of Consent - F1000research

Patient participation is the sine qua non condition for clinical trials to happen and for medical research to improve 1 , 2 ( ). However, in practice, the informed consent process is hard to handle in a rigorous and satisfactory way. The US Food and Drug Administration (FDA) reports some metrics that are related to the frequency of clinical investigator-related deficiencies, which show that almost 10% of trials they monitored suffer from consent collection issues, such as failure to re-consent when new information becomes available, use of expired forms or non-validated, unapproved forms, consent document not signed or not dated, missing pages in consent document provided to participants, failure to obtain written informed consent, parental permission obtained after child assent, changes made to the consent documents by hand and without IRB approval 3 , 4 ( ; ). The study by Seife 5 analysed hundreds of clinical trial FDA inspection documents, covering the 19982013 period, and showed that a substantial number of them presented evidence of research misconduct, among which 53% were related to failure to protect the safety of patients and/or issues with oversight or informed consent. This can lead to dramatic events, as in France in January 2016: a trial testing the BIA 10-2474 as an analgesic molecule caused the death of a participant. The French health agency IGAS appeared to prove that re-consent was not sought after major neurological side effects occurred in some patients, leading to participants being included in the clinical trial without being informed of this issue and still receiving doses of the analgesic molecule, ( ; , version of 2016.09.05). Another example in the UK occurred when a general practitioner was struck off after testing drugs on patients who did Continue reading >>

Assignment 4 Literature Review For 3 Papers Bitcoin Wallet

Bitcoin technology as we know today, has grown vastly due to its security, scalability as well as being an independent cryptocurrency that does not rely upon conversion and inflation of international borders. All in all, Bitcoin currency is a decentralized platform where no one organization or state is responsible for its control and circulation. This very characteristic makes. Bitcoin technology so vastly used in large business, but the question arises, how secure is bitcoin currency? The motivation of this literature review is to look into various peer reviewed journals to help investigate this question. The area of concern regarding this particular research is look at Bitcoin technology and how it can assist us in building a secure bitcoin wallet that can be used in day to day life. We want to investigate if bitcoin wallets have the capability and easiness to be used in a normal day to day environment. The three articles we will present in this literature review will be looking into various Bitcoin protection mechanisms, their security threats along with bitcoin transactions in the light of secure block chains. Bitcoins, Its Advantages and Security Threats, by Archana M. Naware Consumers no longer need to depend solely on government-issued money for their online financial transactions.

"breaking Down The Blockchain Hype Towards A Blockchain Market Engine" By Benedikt Notheisen, Florian Hawlitschek Et Al.

Christof Weinhardt, Karlsruhe Institute of Technology, Karlsruhe, GER Follow The blockchain has reached the tip of a global hype across a variety of industries. The potential of this technology, inter alia building the fundament of Bitcoin, is assumed to be immense and disruptive particularly for the financial industry. FinTech start-ups as well as established players however are just about to explore the true potential of blockchain technology as the fundament of (financial) markets. Before this backdrop, Information Systems research is making valuable contributions to the field by integrating the technical view on blockchain with interdisciplinary research approaches. Our contribution to the growing body of Information Systems literature in the context of the blockchain is twofold: First, we conduct a comprehensive literature review of the most relevant and recent IS research on blockchain. Second, based on the findings of our review, we build on existing research and propose a Blockchain Market Engineering Framework, which can support researchers as well as practitioners in analyzing and designing the elements of blockchain-based markets on an individual and global level. In addition, we go beyond a purely analytical perspective and provide a toolbox to support the active construction of blockchain-based ecosystems and infrastructures. In doing so we pave the way for future research that will help to break down the blockchain hype. Continue reading >>

Hitching Healthcare To The Chain: An Introduction To Blockchain Technology In The Healthcare Sector

Hitching Healthcare To The Chain: An Introduction To Blockchain Technology In The Healthcare Sector

Hitching Healthcare to the Chain: An Introduction to Blockchain Technology in the Healthcare Sector Blockchain is a way for people to solve problems by sharing things. Health services must balance patient care with information privacy, access, and completeness. The massive scale of the healthcare industry also amplifies the importance of cost control. The promise of blockchain technology in health services, combined with application layers built atop it, is to be a mechanism that provides utmost privacy while ensuring that appropriate users can easily add to and access a permanent record of information. Blockchains, also called distributed ledgers, enable a combination of cost reduction and increased accessibility to information by connecting stakeholders directly without requirements for third-party brokers, potentially giving better results at lower costs. New ventures are looking to apply blockchain technology to solve real-world problems, including efforts to track public health, centralize research data, monitor and fulfill prescriptions, lower administrative overheads, and organize patient data from an increasing number of inputs. Here, concrete examples of the application of blockchain technology in the health sector are described, touching on near-term promise and challenges. Health is the foundation of an engaged and happy life, and modern humans have been the fortunate beneficiaries of great advances in medical technology (Collins, 2015). With each new technology, more clues become available to decipher the problems that plague our well-being. The advent of individualized information from cheaper genome sequencing, the Internet of Things, and widespread collection of health data may enable researchers to solve formerly inaccessible health problems. However, w Continue reading >>
