Securing the Chain
Securing the chain KPMG International kpmg.com/blockchain360 Foreword It’s no secret that blockchain1 is a potential game changer in financial services and other industries. This is evident by the US$1B investment2 in the technology last year alone. Or the fact that you don’t have to look very far for blockchain use cases, which are as diverse as a foreign exchange market in financial services to the pork supply chain in consumer retailing. Some even see blockchain as a “foundational” technology set to disrupt, enable and change business processing, as we know it across industries. To date, much of the blockchain frenzy has centered on its vast transformative potential across entire industries. So, organizations have focused squarely on “how” they can use blockchain for business. Yet, as more proof of concepts move toward practical implementations and cyber threats rapidly grow in number and sophistication, security and risk management can no longer take a backseat. In addition to “how”, the question then becomes, “Is blockchain secure for my business?” Simply put, it can be. But, not by just turning the key. Security will depend on a variety of factors, none the least of which requires a robust risk management framework. Consider, for example, that as many as half of vulnerability exploitations occur within 10 to 100 days after they are published according to one study3. Then add in the number of threats that are already known. Next, factor in the plethora of unknowns that accompany emerging technologies and you quickly see why a comprehensive view of your risk and threat landscape is necessary. -
Understanding the Motivations, Challenges and Needs of Blockchain Software Developers: a Survey
Empirical Software Engineering manuscript No. (will be inserted by the editor) Understanding the Motivations, Challenges and Needs of Blockchain Software Developers: A Survey Amiangshu Bosu · Anindya Iqbal · Rifat Shahriyar · Partha Chakroborty Received: November 6, 2018 / Accepted: March 19, 2019 Abstract The blockchain technology has potential applications in various areas such as smart-contracts, Internet of Things (IoT), land registry, supply chain man- agement, storing medical data, and identity management. Although the Github currently hosts more than six thousand active Blockchain software (BCS) projects, few software engineering research has investigated these projects and its' contrib- utors. Although the number of BCS projects is growing rapidly, the motivations, challenges, and needs of BCS developers remain a puzzle. Therefore, the primary objective of this study is to understand the motivations, challenges, and needs of BCS developers and analyze the differences between BCS and non-BCS development. On this goal, we sent an online survey to 1,604 active BCS developers identified via mining the Github repositories of 145 popular BCS projects. The survey received 156 responses that met our criteria for analysis. The results suggest that the majority of the BCS developers are experienced in non-BCS development and are primarily motivated by the ideology of creating a decentralized financial system. Although most of the BCS projects are Open Source Software (OSS) projects by nature, more than 93% of our respondents found BCS development somewhat different from a non-BCS development as BCS projects have higher emphasis on security and reliability than most of the non- BCS projects. Other differences include: higher costs of defects, decentralized and hostile environment, technological complexity, and difficulty in upgrading the soft- ware after release. -

A REVOLUTION IN TRUST Distributed Ledger Technology in Relief & Development MAY 2017 “The principal challenge associated with [DLT] is a lack of awareness of the technology, especially in sectors other than banking, and a lack of widespread understanding of how it works.” - Deloitte Executive Summary1 The Upside In 2016, the blockchain was recognized as one of the top 10 In a recent report, Accenture surveyed emerging technologies by the World Economic Forum.2 The cost data from eight of the world’s ten potential of the blockchain and distributed ledger technology largest investment banks, with the goal of putting a dollar figure against potential (hereinafter “DLT”) to deliver benefits is significant. Gartner cost savings that might be achieved with estimates that DLT will result in $176 billion in added business DLT. The report concluded that the value by 2025; that total reaches $3.1 trillion by 2030.3 banks analyzed could reduce infrastructure costs by an average $8 to Investment in the field reflects the widespread belief that the $12 billion a year. The survey mapped technology can deliver value. Numerous trials, and some more than 50 operational cost metrics deployments, can be found across multiple sectors. and found the savings would break down as follows: Over two dozen countries are investing in DLT 70% savings on central financial More than 2,500 patents have been filed in the last 3 reporting 4 30-50% savings on compliance years 50% savings on centralized operations As of Q4, 2016, 28 of the top 30 banks were engaged in 50% savings on business blockchain proofs-of-concept operations. -
A Survey on Volatility Fluctuations in the Decentralized Cryptocurrency Financial Assets
Journal of Risk and Financial Management Review A Survey on Volatility Fluctuations in the Decentralized Cryptocurrency Financial Assets Nikolaos A. Kyriazis Department of Economics, University of Thessaly, 38333 Volos, Greece; [email protected] Abstract: This study is an integrated survey of GARCH methodologies applications on 67 empirical papers that focus on cryptocurrencies. More sophisticated GARCH models are found to better explain the fluctuations in the volatility of cryptocurrencies. The main characteristics and the optimal approaches for modeling returns and volatility of cryptocurrencies are under scrutiny. Moreover, emphasis is placed on interconnectedness and hedging and/or diversifying abilities, measurement of profit-making and risk, efficiency and herding behavior. This leads to fruitful results and sheds light on a broad spectrum of aspects. In-depth analysis is provided of the speculative character of digital currencies and the possibility of improvement of the risk–return trade-off in investors’ portfolios. Overall, it is found that the inclusion of Bitcoin in portfolios with conventional assets could significantly improve the risk–return trade-off of investors’ decisions. Results on whether Bitcoin resembles gold are split. The same is true about whether Bitcoins volatility presents larger reactions to positive or negative shocks. Cryptocurrency markets are found not to be efficient. This study provides a roadmap for researchers and investors as well as authorities.

Cuba: Issues for the 111Th Congress
Cuba: Issues for the 111th Congress Mark P. Sullivan Specialist in Latin American Affairs September 3, 2010 Congressional Research Service 7-5700 www.crs.gov R40193 CRS Report for Congress Prepared for Members and Committees of Congress Cuba: Issues for the 111th Congress Summary Cuba remains a hard-line communist state with a poor record on human rights. The country’s political succession in 2006 from the long-ruling Fidel Castro to his brother Raúl was characterized by a remarkable degree of stability. The government of Raúl Castro has implemented limited economic policy changes, but there has been disappointment that further reforms have not been forthcoming. The economy was hard hit by storms in 2008, and the global financial crisis has caused further strains. Few observers expect the government to ease its tight control over the political system, although it did agree in July 2010 to release 52 political prisoners after talks with the Cuban Catholic Church. Since the early 1960s, U.S. policy has consisted largely of isolating Cuba through economic sanctions. A second policy component has consisted of support measures for the Cuban people, including U.S.-sponsored broadcasting and support for human rights activists. In light of Fidel Castro’s departure as head of government, many observers have called for a re-examination of policy with two broad approaches advanced: an approach that would maintain the dual-track policy of isolating the Cuban government while providing support to the Cuban people; and an approach aimed at changing attitudes in the Cuban government and society through increased engagement. -

A Decentralized Digital Content Marketplace
LBRY: A Decentralized Digital Content Marketplace Alex Grintsvayg ([email protected]), Jeremy Kauman ([email protected]) Introduction LBRY is a protocol for accessing and publishing digital content in a global, decentralized marketplace. LBRY uses a public blockchain to provide a single shared index of published content, as well as content discovery and payment. Clients can use LBRY to publish, host, find, download, and pay for content — books, movies, music, or anything else that can be represented as a stream of bits. The protocol is permissionless and censorship-resistant, which means that participation is open to everyone and no one can unilaterally block or remove content. Before LBRY, publishers had to choose between a centralized host such as Amazon or Youtube, or a protocol like Bittorrent. Centralized platforms suer from several problems because their incentives are not aligned with the incentives of their users. Hosts engage in rent-seeking behavior, oen extracting 30-55% of creator profits. They enforce opaque and arbitrary rules on creators, and change those rules without warning or community input. They choose to censor content at the behest of repressive regimes around the world, in exchange for access to more users and higher profits for themselves. Bittorrent does not have these faults, but it has problems of its own. It is only useful if one already knows the infohash of the content they seek, and there is no way to discover these hashes within the protocol. Even using an external search engine does not provide a comprehensive list of what is available on the network. There are no incentives for users to seed content, and Bittorrent largely works because users earn status through private communities, are nice, or simply fail to understand what their client is doing. -
Security Analysis Methods on Ethereum Smart Contract Vulnerabilities — a Survey

Abstract—Smart contracts are software programs featuring user [4]. In consequence of these issues of the traditional both traditional applications and distributed data storage on financial systems, the technology advances in peer to peer blockchains. Ethereum is a prominent blockchain platform with network and decentralized data management were headed up the support of smart contracts. The smart contracts act as autonomous agents in critical decentralized applications and as the way of mitigation. In recent years, the blockchain hold a significant amount of cryptocurrency to perform trusted technology is being the prominent mechanism which uses transactions and agreements. Millions of dollars as part of the distributed ledger technology (DLT) to implement digitalized assets held by the smart contracts were stolen or frozen through and decentralized public ledger to keep all cryptocurrency the notorious attacks just between 2016 and 2018, such as the transactions [1], [5], [6], [7], [8]. Blockchain is a public DAO attack, Parity Multi-Sig Wallet attack, and the integer underflow/overflow attacks. These attacks were caused by a electronic ledger equivalent to a distributed database. It can combination of technical flaws in designing and implementing be openly shared among the disparate users to create an software codes. However, many more vulnerabilities of less sever- immutable record of their transactions [7], [9], [10], [11], ity are to be discovered because of the scripting natures of the [12], [13].

Law and the Blockchain
Law and the Blockchain Usha 1K Rodrigues* ABSTRACT: All contracts are necessarily incomplete. The inefficiencies of bargainingover every contingency, coupled with humans' innate bounded rationality, mean that contracts cannot anticipate and address every potential eventuality. One role of law is to fill gaps in incomplete contracts with default rules. Emerging technologies have created new, yet equally incomplete, types of contracts that exist outside of this traditionalgapfilling legal role. The blockchain is a distributed ledger that allows the cryptographic recording of transactions and permits "smart" contracts that self-execute automatically if their conditions are met. Because humans code the contracts of the blockchain, gaps in these contracts will arise. Yet in the world of "smart contracting"on the blockchain, there is no placefor the law to step in to supply default rules-no "legal intervention point." The lack of a legal intervention point means that law on the blockchain works in a fundamentally different way from law in the corporealworld. Business organizationallaw provides a prime example of how the law uses default rules to fill gaps in an incomplete contract and how the law works differently in the blockchain context. I.
