The Blockchain and the New Architecture of Trust

How the blockchain—a system built on foundations of mutual mistrust—can become trustworthy. The blockchain entered the world on January 3, 2009, introducing an innovative new trust architecture: an environment in which users trust a system—for example, a shared ledger of information—without necessarily trusting any of its components. The cryptocurrency Bitcoin is the most famous implementation of the blockchain, but hundreds of other companies have been founded and billions of dollars invested in similar applications since Bitcoin's launch. Some see the blockchain as offering more opportunities for criminal behavior than benefits to society. In this book, Kevin Werbach shows how a technology resting on foundations of mutual mistrust can become trustworthy. The blockchain, built on open software and decentralized foundations that allow anyone to participate, seems like a threat to any form of regulation. In fact, Werbach argues, law and the blockchain need each other. Blockchain systems that ignore law and governance are likely to fail, or to become outlaw technologies irrelevant to the mainstream economy. That, Werbach cautions, would be a tragic waste of potential. If, however, we recognize the blockchain as a kind of legal technology that shapes behavior in new ways, it can be harnessed to create tremendous business and social value.

While there are many books on blockchains, this guide focuses on blockchain applications for business. The target audience is business students, professionals, and managers who want to learn about the overall blockchain landscape -- the investments, the size of markets, major players and the global reach -- as well as the potential business value of blockchain applications and the challenges that must be overcome to achieve that value. We present use cases and derive action principles for building enterprise blockchain capabilities. Readers will learn enough about the underlying technologies to speak intelligently to technology experts in the space, as the guide also covers the blockchain protocols, code bases and provides a glossary of terms. We use this guide as the textbook for our undergraduate and graduate Blockchain Fundamentals course at the University of Arkansas. Other professors interested in adopting this guide for instructional purposes are welcome to contact the author for supporting instructional materials.

Coins of patience are yours as you skillfully circumnutate from the first block to the last. Views and opinions expressed in this book are those of the author and do not reflect the policy or position of Hyperledger, Ethereum or any other body or organization mentioned.

Can Blockchain Technology Replace Trust in Markets Affected by Moral Hazard?

The aim of this thesis is to explore implementations of blockchain technology in markets affected by moral hazard and to find out if trusted intermediaries can be replaced in those markets. After a theoretical explanation of blockchain technology, three different use cases in the sectors of elections, land administration and foreign aid are examined with a focus on possible limitations and hurdles that need to be overcome. In conclusion, it seems unlikely that trusted intermediaries in any of the three examined markets can be replaced by blockchain technology in the near future. However, there are various promising implementations of permissioned blockchains to securely digitize processes in all three sectors and make transactions cheaper, faster, more transparent and easier to audit. Many forms of abuse of authority and moral hazard in general could be prevented or at least made easier to detect, thereby not replacing, but at least minimizing the need for trust.

Blockchain Technology is invented by Bitcoin which makes it the backbone of an innovative type of internet. It is a public and digital ledger that distributes data without allowing its copy. It transacts the information from all the systems of its users so that its registered users can't escape retrospectively. It was invented to smoothen out the process of online transactions. Moreover, its purpose is also to make the transactions secure. That's why it is the most reliable and valid technology that does not even rely on any other software or person.

*Blockchain for the non-developer Book 1: Blockchain 101: Distributed Ledger Technology (DLT) Book 2: Blockchain 101: Forking, Smart Contracts, Scaling, & Permissioned States This Concise Reads series is set up in short 1-hour explanations of blockchain technology to educate the general public and students planning to make a career in this exciting new field. As it was in the early 2000s when students were foregoing careers in banking for careers in internet startups, today students are doubling down on blockchain classes and internships to build an exciting career for themselves. This first guide in the series explains the core technology behind blockchains-namely: what is blockchain, what came before bitcoin, who is Satoshi? what exactly is a block and how is it created from code? what is distributed ledger technology or DLT and why do we call it that? how do we reach 'consensus' and what does that mean? What is proof of work or proof of stake and what are other algorithms that blockchain security is founded on? What are the basics of its technical architecture (things like hashes, transactions, ledgers, and linking of chains) In the second guide, we'll explore: Forking Scaling Smart contracts Permissioned and permissionless technology and how they are used The second guide was a lot of fun to write, but to understand and appreciate it, you'll need to go through the basics in the first guide. Introduction excerpt: The rapid adoption of blockchain mimics the rapid adoption of internet technology in the 1990s. Today we are in an exciting part of the cycle where hundreds of technology startups are raising funds through Initial Coin Offerings (ICOs) to bring this technology mainstream. This is reminiscent of the hundreds of Initial Public Offerings (IPOs) of 1999. As we recall, there was much enthusiasm for the technology which fueled the bubble that ultimately burst in 2000. Speculators were so excited about the new technology that they did not complete their due diligence on the business plan and whether these companies would ultimately become profitable. In 1999, there were 457 IPOs, many of which doubled in price within the first day of trading. By the time the dot-com bubble burst and investors realized many of the companies could not become profitable, the interest in and number of new IPOs dropped to only 76 by 2001. However, the companies with the best business plans survived and turned the skeptics into consumers over the next decade. Some of these companies are Amazon, eBay, and Priceline. We are in the same 1999 bubble, and only a few of the blockchain startups will survive and will make consumers of the skeptics over the next decade.
