"[A] subtle, and useful, investigation of what blockchain is, and what we might reasonably expect it to accomplish...Even more than AI, blockchain is something most executives know they should care about, but haven't yet really figured out how to use. Casey and Vigna's book would be a good place to start." --Strategy + Business
"An in-depth, fair, and engaging account of a massive technological shift that affects everyone." --Business Insider
"References to bitcoin (the currency) and blockchain (the accounting ledger) are increasing at warp speed, and many of us are struggling to keep up. This book serves as a guide to this new economic order, designed to create a safer and fairer system for global transactions in part by cutting out the middleman (banks and government, for starters)." --The Toronto Star
"The authors ably explain highly technical information in layperson's terms, and the text is neither too dense nor too basic. Readers may pick this one up for the Bitcoin connection and find themselves fascinated with the blockchain's potential to change the world's financial systems for the better." --Booklist
"Blockchain represents nothing less than the second era of the internet, with the potential to fundamentally change the modern digital economy. The Truth Machine offers important insight and a concrete vision into the transformative potential of the blockchain from two leading thinkers in this nascent technology. This is a must-read for anyone looking to understand how the blockchain can help solve some of the most pressing social and economic issues of our time." --Don Tapscott, Executive Chairman, Blockchain Research Institute and co-author of Blockchain Revolution: How the Technology Behind Bitcoin is Changing Money, Business, and the World
"With thoughtful and well researched analysis, The Truth Machine leads you through a history of cryptocurrencies and blockchains that reveals the path forward towards a decentralized economy, one in which opportunity and access are widely spread." --Andreas M Antonopoulos, author of Mastering Bitcoin and The Internet of Money series
"The Truth Machine is a brilliant, beautifully written guide to the blockchain revolution that is redefining "trust" for our increasingly globalized world." --Hernando de Soto, President of the Institute for Liberty and Democracy, author of The Mystery of Capital
"Casey and Vigna are among the blockchain and digital-currency sector's most important visionaries. They are shaping a new understanding of how we can gain greater personal control over our data, assets, identities and creations to forge a more inclusive, collaborative and innovative society." --Imogen Heap, Grammy award-winning singer-songwriter and founder of Mycelia
"Casey and Vigna have done it again! It turns out that digital currencies may only be the spark for the next major revolution in business and society. The implications of trust being the blockchain's real killer app cannot be ignored by any serious investor." --"Downtown" Josh Brown, CEO of Ritholtz Wealth Management, star of CNBC's The Halftime Report
"This unparalleled examination of the blockchain landscape will open people's eyes to how a decentralized information system can level the playing field for humanity." --Mariana Dahan, founder and CEO, World Identity Network, first coordinator of The World Bank's Identification for Development (ID4D) Initiative
"In The Truth Machine, Casey and Vigna describe, in vivid detail, both the theory and practice of the coming block-chain revolution, giving us a powerful technological roadmap to a more participatory future in the digital age." --Jeremy Rifkin, author of The Zero Marginal Cost Society
"[The] world...is at a digital and legal turning point. The 'truth, ' Casey and Vigna show us, is that to move forward we must rethink how information, markets, and value work. A wonderful read--heartily recommended." --Brett King, bestselling author of Augmented, host of the Breaking Banks Radio Show

Derzeit tritt ein Problem beim Filtern der Rezensionen auf. Bitte versuchen Sie es später noch einmal.
In the few places where the book makes an attempt to explain blockchain technology, it is regrettably wrong. For example, on page 65 the authors try to explain how Bitcoin authorises transaction based on digital signatures. They write: “…When the user ‘signs’ their public key with their private key …“. .... Oh dear, nothing could be more far from the truth about digital signature than claiming that the public key is signed with the private key.
The book is full of useless facts, meaningless episodes, unsubstantiated claims, and incomprehensible associations. The text appears as immature pseudo-intellectual rigmarole that is only remotely associated with Blockchain, if anything at all.
If you are looking for intellectually shallow material to brag with half-true blockchain “knowledge” at cocktail-parties, read on, the book is for you.
For all others who appreciate concise and right to the point explanations about blockchain without any fluff, side tracking or factual errors: stay away from this book.

The authors provide a current snapshot of industry developments and a thoughtful review of the challenges, risks, and opportunities that now present themselves. One of those challenges is scalability. For reasons I won’t try to explain here, that one issue has fractured the industry into permissionless (e.g., Bitcoin, Ethereum) and permissioned segments, the former behaving more like the original ideal of the democratized digital economy and the latter being a variation of the gatekeepers model (think banks) we have today.
But why should you care if you are outside the universe of tech investors, banks, entrepreneurs, and engineers? Because tech exists to serve a larger purpose. And that larger purpose, in this case, as the authors point out, extends, at a minimum, to the Internet of Things, but may ultimately impact not just our economy, but our society and our democracy. It could, as one example the authors offer, eventually lead to the commercialization of your personal reputation. (Admittedly a long way off.)
This is not a book about Bitcoin, although it does come up a lot. The relevance is that Bitcoin uses blockchain technology. And whether you think Bitcoin is fool’s gold or not, the underlying technology has worked pretty well. In nine years, no one has hacked the system.
The Internet and its digital revolution have one over-riding problem: digital data can be replicated. In essence that means that any digital system can be compromised. And as we’ve discovered there is no shortage of people in the world who will make every attempt to do so. It’s easy money and some people, for some perverse reason, consider it “fun.” (Or payback, perhaps.)
Protecting the integrity of the digital world, as a result, has proven to be a monumental task. It’s expensive, requires a lot of people, and ultimately fails. In part, this has contributed to the reality that the Internet, once perceived to be the ultimate egalitarian state, is now the ultimate monopoly. A handful of giant companies, whose names you can easily identify, now control it. And while no one really knows what that will mean longer term, the yellow flags are starting to be hoisted, particularly following the 2016 presidential election.
The easiest way to think of blockchain, perhaps, is that it goes back to the original digital ideal of the pure democracy, but incorporates security protocols that reduce the forces favoring consolidation of the gatekeepers. In short, it is the architecture that makes good on the original vision. Maybe.
There are a few hurdles, however. The first is that you have to accept that the system is better, but not perfect. Before you can evaluate that decision, however, you must accept that the current system of accounting that governs our banks and corporations is far from perfect, too. Accounting is not truth. And that is the truth. Accounting is an approximation of truth and sometimes the gap, as we saw during the 2008 financial crisis, can be huge – as in big enough to cause a “healthy” bank like Lehman Brothers to disappear overnight.
That, I fear, is going to be a very hard sell to the average citizen. Or, more accurately, once you let the cat out of the bag people are going to be aghast and it is unlikely they will see doubling down on technology as the best way forward. It is human nature to not want to think about what we don’t want to think about. And most people don’t want to think about the fact that Wall Street really has no idea what the companies whose stocks it trades are worth. Or that our biggest employers really don’t know if they are making or losing money. That sounds a lot like chaos and we don’t like to go there, particularly since that same Wall Street is playing its game of chance with our retirement and our savings.
It’s important to accept that, however, because blockchains do not promise perfection. They might be better, but better is relative. Digital, by definition, means replicable, for good or bad. The risk can be reduced, but it can’t be eliminated.
And that brings us to the second big challenge. Like any system of security and trust, blockchain systems will require that we all agree on some fundamental rules. And this, I fear, will be an even bigger hurdle than the first. And the reason is the asymmetry of power that exists today.
Our economy and our society, and particularly our politics, are today ruled by minorities. It might be a numeric minority, or it might not be, but its opinion falls short of a complete consensus. There is no democracy if by democracy we mean everyone has an equal say in things. That’s not even close to being today’s reality.
And as we witness day in and day out, the people who benefit from that asymmetry today want to make the balance of power even more asymmetrical – to their benefit, of course. That’s why we have lobbyists and why corporations and wealthy individuals invest so much money in the political process. If power were allocated symmetrically, it would be a lousy investment.
It is that asymmetry, even more than the unanticipated security challenge, that has allowed corporate America to hijack the digital economy to the degree it has. It’s not just that the corporations did it; it is the fact that Washington let them, and in fact facilitated them. (And we, the users, of course, let the politicians let them.)
I don’t yet see, frankly, how blockchain technology gets around that. The banks and the tech giants will seize the agenda and rework it to their advantage, as it appears, from the information provided in this book, they are already doing. In the end, if that continues, we will have the next big thing that looks and smells a little different but is the same old thing when it comes to asymmetric power. Maybe a few new products, like crypotcurrencies or blockchain-enabled supply chains, but the same old players pulling the same old strings to their advantage.
My ultimate takeaway from the book: It’s ultimately a battle between an ideology of individualism and an ideology built on the common good. Liberal democracy, as we know it today, and have known it since the founding of the country, is built on a foundation of individualism (e.g, individual rights, freedoms, and opportunities). And it has worked remarkably well.
The Achilles Heel of individualism, however, is the asymmetric allocation of power. It is a weakness, moreover, that has been great exaggerated and accelerated by technology. Technology, to date, has done nothing quite so dramatically as it has enhanced the asymmetric allocation of power in our economy, our society, and our politics.
The ultimate promise of blockchain technology, therefore, as I think the authors see it, is the opportunity to double down on individualism. The blockchain, might, if the predictions hold, provide the means to overcome the inherent inequities of modern capitalism fueled by the creation of digital monopolies.
They might be right. But, as Yogi Berra noted, “In theory, there is no difference between theory and practice, but in practice there is.” And I’m with Yogi on this one. I don’t see the 1%, however you define it, just walking away and letting the other 99% of us back into the fight.
Perhaps more importantly, Washington shows no resolve to do anything to impede the asymmetric accumulation of power by corporations and wealthy individuals. According to the authors, while the central banks of England, Japan, and Canada are all actively exploring blockchain technologies, our own government seems content to leave it in the hands of private initiatives like the corporate consortium, Hyperledger, dominated by companies like IBM and Intel.
I may be wrong. I dearly hope I am. At any rate, it’s a very good book and you will do yourself an injustice if you don’t read it.
As stated in this book, “If the future foreseen by this book comes to pass, we’ll witness the biggest employment shakeup the world has ever seen. And this time, the most vulnerable jobs are not the usual suspects: the factory workers, the low-level clerks, or the retail store assistants.
“Now it’s the accountants, the bankers, the portfolio managers, the insurers, the title officers, the escrow agents, and the trustees—and, yes, even the lawyers. To be sure, the common refrain that lawyers will be replaced by “smart contracts” is somewhat inaccurate since the terms of agreements, the actual contracts themselves, will still need to be negotiated by human beings. Nonetheless, the legal industry is also in for a huge shakeup. Lawyers who don’t understand code are likely going to be valued far less than those who do. (One of the most employable joint degrees to have will be a law-plus–computer science degree.) In any case, you get the idea: the middle class is facing a tidal wave.”
Decentralized blockchain technology is a record keeping ledger that is transparent immutable and uses algorithms to used smart contracts and this will drastically cut costs and speed up processes that use to take days. All of this is being done automatically through little human oversight.
Let me give you a few examples:
In banking, the processed syndicated loans, which now takes weeks, will be processed in minutes. Best of all, these transactions become programmable and able to communicate information and instructions as well.
Remember when Chipotle’s customers got sick from contaminated foods? Decentralized supply chains would almost eliminate the spread of food contamination because each step within the process would be noted within the blockchain ledger and would be traceable and this would naturally enhance trust in the data.
The book also stated: “The World Food Program (WFP), a UN agency that feeds 80 million people worldwide, is putting 10,000 Azraq refugees through a pilot that uses a blockchain system to better coordinate food distribution. In doing so, the WFP is tackling a giant administrative challenge: how to ensure, in an environment where theft is rampant, and few people carry personal identifying documents, that everyone gets their fair share of food.
“This Azraq blockchain pilot ensures that people aren’t double-spending their food entitlements. That’s a pretty important requirement in refugee camps, where supplies are limited and where organized crime outfits have been known to steal and hoard food for profit.”
Ride sharing services like Uber will also be replaced by services like Tel Aviv-based, blockchain-powered ride-sharing application that have no middlemen or controlling authority.
Medical record keeping will advance and allow us to centralize and organize all our records in a secured platform that we control.
Anything can be digitized—a title, contracts, copyrights, personal IDs, solar grids, commodity exchanges, investment funds, blockchain-certified marriage certificates, online voting systems, and supply-chain platforms.
Blockchain even has the likelihood of helping us reduce our carbon-missions output which will help with climate change.
Our ability to do background checks will be dramatic. For example, we will know if an individual hangs out with high-school dropouts or people with graduate degrees. It will show our payment history, sleep patterns, travel history, and, of course, our online surfing.
If social media companies agree to share our data, a whole new identity could be formed that would be much more informative than anything produced by, say, credit score keepers such as Equifax.
The book states: “This is precisely what a new breed of algorithmic credit-scoring companies and other such big data–driven startups are doing. Putting all of that into a blockchain-proven system could be a powerful way to get people to trust each other and expand their social and economic exchanges.”
Decentralized blockchains are just the beginning. Our world is changing faster than we realize through artificial intelligence, biotechnologies, quantum computing, and advanced materials, and these discoveries are creating a radical shift in the way we live.
