This book takes you on a journey to the future of currency and the blockchain universe. A 360-Degrees onboarding guide Starting from the basics, it moves on to explaining everything you need to know to make up your own mind on the potential, strengths, weaknesses, and limitations of Bitcoin, cryptocurrencies, the blockchain technology and how they will change the world (or not). The book addresses the following: 1) BITCOIN AND THE BLOCKCHAIN Understand the inner workings of Bitcoin and the Blockchain step by step. How are bitcoins created? What are the rules? What is a decentralized consensus? How secure is it? What are the challenges and potential solutions? 2) THE ECOSYSTEM Get ready to know everything you need before using cryptocurrencies. What are your options to store them? How do wallets differ from one another? Where and how can you spend them? 3) IS IT MONEY? IS IT CURRENCY? Make up your mind on whether Bitcoin has what it takes to be real money or currency. Through a historical perspective, discover what constitutes good money and a good currency before reflecting on whether Bitcoin can be money or currency. 4) THE BIGGER PICTURE Sense the bigger picture surrounding Bitcoin. How do political, economic, and regulatory forces affect Bitcoin and how does Bitcoin affect them? Given Bitcoin's strengths and weaknesses, what role is it likely to play in the future? 5) CRYPTOCURRENCIES AND INNOVATIONS Push your thinking to new levels by discovering alternative cryptocurrencies serving different purposes and using different consensus or distribution mechanisms (such as ICOs). Ever heard of auxiliary proof-of-work and its pitfalls? 6) BEYOND CRYPTOCURRENCIES Discover the true potential of the blockchain technology, from smart-contracts to decentralized autonomous organizations (DAOs). This part of the book unleashes what blockchain means for your business and for society. How does it reinvent our identity, basic income, and our democracies?

The worlds of finance and technology have been rocked by Bitcoin and other cryptocurrencies: encrypted digital currency created by complex computer algorithms. First developed in 2009 and launching several speculative frenzies, cryptocurrencies have created and destroyed fortunes over their turbulent history. Across years of New York Times articles, readers will discover the unfolding story of a technology that, while rarely performing as promised, has produced profound effects that cannot be ignored.

After over a decade of Bitcoin, which has now moved beyond lore and hype into an increasingly robust star in the firmament of global assets, a new and more important question has arisen. What happens beyond Bitcoin? The answer is decentralised finance - 'DeFi'. Tech and finance experts Steven Boykey Sidley and Simon Dingle argue that DeFi - which enables all manner of financial transactions to take place directly, person to person, without the involvement of financial institutions - will redesign the cogs and wheels in the engines of trust, and make the remarkable rise of Bitcoin look quaint by comparison. It will disrupt and displace fine and respectable companies, if not entire industries. Sidley and Dingle explain how DeFi works, introduce the organisations and individuals that comprise the new industry, and identify the likely winners and losers in the coming revolution.

Since the launch of Bitcoin in 2009 several hundred different ‘cryptocurrencies’ have been developed and become accepted for a wide variety of transactions in leading online commercial marketplaces and the ‘sharing economy’, as well as by more traditional retailers, manufacturers, and even by charities and political parties. Bitcoin and its competitors have also garnered attention for their wildly fluctuating values as well as implication in international money laundering, Ponzi schemes and online trade in illicit goods and services across borders. These and other controversies surrounding cryptocurrencies have induced varying governance responses by central banks, government ministries, international organizations, and industry regulators worldwide. Besides formal attempts to ban Bitcoin, there have been multifaceted efforts to incorporate elements of blockchains, the peer-to-peer technology underlying cryptocurrencies, in the wider exchange, recording, and broadcasting of digital transactions. Blockchains are being mobilized to support and extend an array of governance activities. The novelty and breadth of growing blockchain-based activities have fuelled both utopian promises and dystopian fears regarding applications of the emergent technology to Bitcoin and beyond. This volume brings scholars of anthropology, economics, Science and Technology Studies, and sociology together with GPE scholars in assessing the actual implications posed by Bitcoin and blockchains for contemporary global governance. Its interdisciplinary contributions provide academics, policymakers, industry practitioners and the general public with more nuanced understandings of technological change in the changing character of governance within and across the borders of nation-states.

In January 2009, a mysterious software developer, Satoshi Nakamoto, exchanged a specially designed code with another developer. The code was a digital currency that Nakamoto had proposed several months before in a paper titled “Bitcoin: A Peer-to-Peer Electronic Cash System.” This was the first Bitcoin transaction. Since then, Bitcoin has become the face of a tech revolution in digital cryptocurrencies based on blockchain technology. Its success has sparked a tech revolution that could fundamentally change global economics. Author Brendan January delves into the world of coders, libertarians, criminals, financial regulators, and crypto-detectives to understand what digital cryptocurrencies have to offer, their limitations and potential pitfalls, security issues, and how they may affect government and financial regulations in the future.

The cryptocurrency trend of the past few years has continued to grow despite widespread predictions that it would just be a flash in the pan. Blockchain is suddenly everyone's favorite buzzword. But what if there's more to this story than meets the eye? What if Digital Currency is about to change the world in ways beyond our imagination? And what if geopolitical forces our politicians don't even understand have already inspired China and Russia to use Digital Currency to attack the U.S. Dollar's dominance over the global financial system?The Dollar has served as the world's reserve currency since 1944, and the fringe benefits have allowed the U.S. Government to borrow and spend beyond its means and run massive trade deficits for decades. Now China and Russia suddenly have a new lever to use which could upset the global balance of power. Who would have guessed that technology breakthroughs conceived by the inventors of cryptocurrency would hand China and Russia just the weapon they needed to attack the Dollar's rule over the global economy? The invention of digital cash enables government-issued digital currency systems that could completely modernize the global monetary system. The potential benefits to society are so great that it's hard to grasp their full magnitude. But a digital currency system introduced by China and Russia could upstage the Dollar and replace it as global reserve currency, causing devastating consequences for the U.S. economy. Which country wins the new digital currency Space Race could change the course of human history.There's plenty of evidence that China and Russia are already hard at work. The Chinese central bank is aggressively hiring Blockchain engineers, but has been suspiciously quiet about what they're working on. Sergei Glaziev, economic advisor to Russian President Vladimir Putin is giving keynote speeches to Blockchain conferences. The Chinese central bank filed more digital currency patents than anyone else in 2017. This book explains why China and Russia are suddenly so interested in Digital Currency technology, and more importantly, what they plan to do with it. Time is short for the U.S. Government to wake up and recognize the threat that now looms over the U.S. Dollar's dominance at the center of the global financial system, and why Digital Currency technology is likely to be the challengers' weapon of choice to defeat the Dollar.Author Erik Townsend is uniquely qualified to sort this puzzle out and tell the entire fascinating story. In his first career, Townsend was a distributed systems architect - an expert in all the technologies used to create cryptocurrencies. In his second career, he was a hedge fund manager who studied reserve currency status extensively. Townsend first gives readers an introduction to both conventional money and digital currency, then gives a detailed introduction to relevant monetary history subjects, and finally ties it all together and explains how a state-sponsored digital currency system could steal the title of global reserve currency from the U.S. Dollar and change the balance of world power.
