In chapter 3, the author describes eight core functions of the global financial service sector which blockchain technology will likely change. Create a new thread, choose one of the core functions described in chapter 3, and explain why it is important in moving today’s economy forward, and provide at least two real examples of the chosen core function being changed by blockchain technology today. Then think of three questions you’d like to ask other students and add these to the end of your thread. The questions should be taken from material you read in Chapter 1, 2, or 3. You’re not trying to test each other, but you are trying to start a discussion.

ACKNOWLEDGMENTS

This book came from the meeting of two minds and two life trajectories. Don had been leading a $4 million syndicated research program called Global Solution Networks (GSN) at the Rotman School of Management, University of Toronto. The initiative was investigating new, networked models of global problem solving and governance. He researched how the Internet was governed by a multistakeholder ecosystem and became interested in digital currencies and their governance. Meanwhile, Alex was an executive with the investment bank Canaccord Genuity. He noticed the growing enthusiasm for early-stage bitcoin and blockchain companies in 2013 and began leading his firm’s efforts in the space. During a father-son ski trip to Mont-Tremblant in early 2014, we brainstormed over dinner about collaborating on this topic, and Alex agreed to lead a research project on the governance of digital currencies, culminating in his white paper, titled A Bitcoin Governance Network. The more we dug into the issues, the more we concluded that this could be the next big thing.

Meanwhile our agent, Wes Neff at the Leigh Bureau, along with Don’s publisher Adrian Zackheim at Portfolio/Penguin (Wikinomics, Macrowikinomics), was encouraging Don to formulate a new book concept. When Alex’s paper became widely recognized as leading thinking in this area, Don approached Alex to be his coauthor. Adrian, to his credit, made us an offer we couldn’t refuse and the book never went to auction, as is normally the case.

We then made what in hindsight was a smart decision. We approached the best book editor we knew, Kirsten Sandberg, formerly of Harvard Business School Press, and asked her to edit our book proposal. She did a spectacular job and our collaboration was so effortless that we asked her to be a full-time member of the book research team. Kirsten participated with us in more than one hundred interviews and collaborated in real time as we tried to understand the myriad issues on the table and develop helpful formulations to explain this extraordinary set of developments to a nontechnical audience. She helped us bring the story to life. In that sense, she was our coauthor and this book would not have appeared, at least in its current comprehensible form, without her. For that, and for all the stimulation and laugh lines, we are very grateful.

Also special thanks to a few people who really rolled up their sleeves to help. Anthony Williams and Joan Bigham of the GSN project worked closely with Alex on the original digital currencies governance paper. Former Cisco executive Joan McCalla did deep research for the chapters on the Internet of Things and also Government and Democracy. We received a lot of familial support. IT executive Bob Tapscott spent many days downloading and getting under the hood of the entire bitcoin blockchain to give us firsthand insights on some of the technical issues. Technology entrepreneur Bill Tapscott came up with the revolutionary idea of a blockchain- based personal carbon credit trading system, and technology executive Niki Tapscott and her husband, financial analyst James Leo, have been great sounding boards throughout. Katherine MacLellan of the Tapscott Group (conveniently a lawyer) tackled some of the tougher issues around smart contracts as well as managing the interview process. Phil Courneyeur was on the lookout daily for juicy material, and David Ticoll provided helpful insights about the state of the digital age so far. Wes Neff and Bill Leigh of the Leigh Bureau helped us craft the book concept (how many books is this, guys?). As always (now more than twenty years), Jody Stevens flawlessly managed the administration for the entire project including databases, finances, and document management, as well as the proofreading and production process—a full-time job, in addition to her other full-time jobs at the Tapscott Group.

Special thanks to Dino Mark Angaritis, the CEO of blockchain company Smartwallet; Joseph Lubin, CEO of the Ethereum development studio Consensus Systems; and Carlos Moreira of fast-growing security company WISeKey—who each spent considerable time with us brainstorming ideas. They are each brilliant and so kind to help us out. Now we get to enjoy witnessing the success of each of their businesses in this space. Also big thanks to the great team at Penguin Random House led by our editor Jesse Maeshiro and overseen by Adrian Zackheim.

Most important, we’d like to give our heartfelt thanks to our wives, Ana Lopes (Don) and Amy Welsman (Alex), who more than tolerated our obsession with cracking this big nut over the better part of a year. We are both very fortunate to have such wonderful life partners.

Writing this book has been a joyous experience for both of us and it’s fair to say that we loved every minute of it. As someone famous once said, “If two people agree on everything, one of them is unnecessary.” We challenged each other daily to test our beliefs and assumptions, and this book is living proof of that healthy and vigorous collaboration. Mind you, collaborating does seem effortless when you share so much DNA and have a shared thirty-year history of exploring the world together. We do hope you find the product of this collaboration important and helpful.

PART I

SAY YOU WANT A REVOLUTION

I

CHAPTER 1

THE TRUST PROTOCOL

t appears that once again, the technological genie has been unleashed from its bottle. Summoned by an unknown person or persons with unclear motives, at an uncertain time in

history, the genie is now at our service for another kick at the can—to transform the economic power grid and the old order of human affairs for the better. If we will it.

Let us explain. The first four decades of the Internet brought us e-mail, the World Wide Web, dot-coms,

social media, the mobile Web, big data, cloud computing, and the early days of the Internet of Things. It has been great for reducing the costs of searching, collaborating, and exchanging information. It has lowered the barriers to entry for new media and entertainment, new forms of retailing and organizing work, and unprecedented digital ventures. Through sensor technology, it has infused intelligence into our wallets, our clothing, our automobiles, our buildings, our cities, and even our biology. It is saturating our environment so completely that soon we will no longer “log on” but rather go about our business and our lives immersed in pervasive technology.

Overall, the Internet has enabled many positive changes—for those with access to it—but it has serious limitations for business and economic activity. The New Yorker could rerun Peter Steiner’s 1993 cartoon of one dog talking to another without revision: “On the Internet, nobody knows you’re a dog.” Online, we still can’t reliably establish one another’s identities or trust one another to transact and exchange money without validation from a third party like a bank or a government. These same intermediaries collect our data and invade our privacy for commercial gain and national security. Even with the Internet, their cost structure excludes some 2.5 billion people from the global financial system. Despite the promise of a peer-to-peer empowered world, the economic and political benefits have proven to be asymmetrical—with power and prosperity channeled to those who already have it, even if they’re no longer earning it. Money is making more money than many people do.

Technology doesn’t create prosperity any more than it destroys privacy. However, in this digital age, technology is at the heart of just about everything—good and bad. It enables humans to value and to violate one another’s rights in profound new ways. The explosion in online communication and commerce is creating more opportunities for cybercrime. Moore’s law of the annual doubling of processing power doubles the power of fraudsters and thieves—“Moore’s Outlaws”1—not to mention spammers, identity thieves, phishers, spies, zombie farmers, hackers, cyberbullies, and datanappers—criminals who unleash ransomware to hold data hostage—the list goes on.

IN SEARCH OF THE TRUST PROTOCOL

As early as 1981, inventors were attempting to solve the Internet’s problems of privacy, security, and inclusion with cryptography. No matter how they reengineered the process, there were always leaks because third parties were involved. Paying with credit cards over the Internet was insecure because users had to divulge too much personal data, and the transaction fees were too high for small payments.

In 1993, a brilliant mathematician named David Chaum came up with eCash, a digital payment system that was “a technically perfect product which made it possible to safely and anonymously pay over the Internet. . . . It was perfectly suited to sending electronic pennies, nickels, and dimes over the Internet.”2 It was so perfect that Microsoft and others were interested in including eCash as a feature in their software.3 The trouble was, online shoppers didn’t care about privacy and security online then. Chaum’s Dutch company DigiCash went bankrupt in 1998.

Around that time, one of Chaum’s associates, Nick Szabo, wrote a short paper entitled “The God Protocol,” a twist on Nobel laureate Leon Lederman’s phrase “the God particle,” referring to the importance of the Higgs boson to modern physics. In his paper, Szabo mused about the creation of a be-all end-all technology protocol, one that designated God the trusted third party in the middle of all transactions: “All the parties would send their inputs to God. God would reliably determine the results and return the outputs. God being the ultimate in confessional discretion, no party would learn anything more about the other parties’ inputs than they could learn from their own inputs and the output.”4 His point was powerful: Doing business on the Internet requires a leap of faith. Because the infrastructure lacks the much-needed security, we often have little choice but to treat the middlemen as if they were deities.

A decade later in 2008, the global financial industry crashed. Perhaps propitiously, a pseudonymous person or persons named Satoshi Nakamoto outlined a new protocol for a peer- to-peer electronic cash system using a cryptocurrency called bitcoin. Cryptocurrencies (digital currencies) are different from traditional fiat currencies because they are not created or controlled by countries. This protocol established a set of rules—in the form of distributed computations— that ensured the integrity of the data exchanged among these billions of devices without going through a trusted third party. This seemingly subtle act set off a spark that has excited, terrified, or otherwise captured the imagination of the computing world and has spread like wildfire to businesses, governments, privacy advocates, social development activists, media theorists, and journalists, to name a few, everywhere.

“They’re like, ‘Oh my god, this is it. This is the big breakthrough. This is the thing we’ve been waiting for,’” said Marc Andreessen, the cocreator of the first commercial Web browser, Netscape, and a big investor in technology ventures. “‘He solved all the problems. Whoever he is should get the Nobel Prize—he’s a genius.’ This is the thing! This is the distributed trust network that the Internet always needed and never had.”5

Today thoughtful people everywhere are trying to understand the implications of a protocol that enables mere mortals to manufacture trust through clever code. This has never happened before—trusted transactions directly between two or more parties, authenticated by mass collaboration and powered by collective self-interests, rather than by large corporations motivated by profit.

It may not be the Almighty, but a trustworthy global platform for our transactions is something very big. We’re calling it the Trust Protocol.

This protocol is the foundation of a growing number of global distributed ledgers called blockchains—of which the bitcoin blockchain is the largest. While the technology is complicated and the word blockchain isn’t exactly sonorous, the main idea is simple. Blockchains enable us to send money directly and safely from me to you, without going through a bank, a credit card company, or PayPal.

Rather than the Internet of Information, it’s the Internet of Value or of Money. It’s also a platform for everyone to know what is true—at least with regard to structured recorded information. At its most basic, it is an open source code: anyone can download it for free, run it, and use it to develop new tools for managing transactions online. As such, it holds the potential for unleashing countless new applications and as yet unrealized capabilities that have the potential to transform many things.

HOW THIS WORLDWIDE LEDGER WORKS

Big banks and some governments are implementing blockchains as distributed ledgers to revolutionize the way information is stored and transactions occur. Their goals are laudable— speed, lower cost, security, fewer errors, and the elimination of central points of attack and failure. These models don’t necessarily involve a cryptocurrency for payments.

However, the most important and far-reaching blockchains are based on Satoshi’s bitcoin model. Here’s how they work.

Bitcoin or other digital currency isn’t saved in a file somewhere; it’s represented by transactions recorded in a blockchain—kind of like a global spreadsheet or ledger, which leverages the resources of a large peer-to-peer bitcoin network to verify and approve each bitcoin transaction. Each blockchain, like the one that uses bitcoin, is distributed: it runs on computers provided by volunteers around the world; there is no central database to hack. The blockchain is public: anyone can view it at any time because it resides on the network, not within a single institution charged with auditing transactions and keeping records. And the blockchain is encrypted: it uses heavy-duty encryption involving public and private keys (rather like the two- key system to access a safety deposit box) to maintain virtual security. You needn’t worry about the weak firewalls of Target or Home Depot or a thieving staffer of Morgan Stanley or the U.S. federal government.

Every ten minutes, like the heartbeat of the bitcoin network, all the transactions conducted are verified, cleared, and stored in a block which is linked to the preceding block, thereby creating a chain. Each block must refer to the preceding block to be valid. This structure permanently time-stamps and stores exchanges of value, preventing anyone from altering the ledger. If you wanted to steal a bitcoin, you’d have to rewrite the coin’s entire history on the blockchain in broad daylight. That’s practically impossible. So the blockchain is a distributed ledger representing a network consensus of every transaction that has ever occurred. Like the World Wide Web of information, it’s the World Wide Ledger of value—a distributed ledger that everyone can download and run on their personal computer.

Some scholars have argued that the invention of double-entry bookkeeping enabled the rise of capitalism and the nation-state. This new digital ledger of economic transactions can be

programmed to record virtually everything of value and importance to humankind: birth and death certificates, marriage licenses, deeds and titles of ownership, educational degrees, financial accounts, medical procedures, insurance claims, votes, provenance of food, and anything else that can be expressed in code.

The new platform enables a reconciliation of digital records regarding just about everything in real time. In fact, soon billions of smart things in the physical world will be sensing, responding, communicating, buying their own electricity and sharing important data, doing everything from protecting our environment to managing our health. This Internet of Everything needs a Ledger of Everything. Business, commerce, and the economy need a Digital Reckoning.

So why should you care? We believe the truth can set us free and distributed trust will profoundly affect people in all walks of life. Maybe you’re a music lover who wants artists to make a living off their art. Or a consumer who wants to know where that hamburger meat really came from. Perhaps you’re an immigrant who’s sick of paying big fees to send money home to loved ones in your ancestral land. Or a Saudi woman who wants to publish her own fashion magazine. Maybe you’re an aid worker who needs to identify land titles of landowners so you can rebuild their homes after an earthquake. Or a citizen fed up with the lack of transparency and accountability of political leaders. Or a user of social media who values your privacy and thinks all the data you generate might be worth something—to you. Even as we write, innovators are building blockchain-based applications that serve these ends. And they are just the beginning.

A RATIONAL EXUBERANCE FOR THE BLOCKCHAIN

For sure, blockchain technology has profound implications for many institutions. Which helps explain all the excitement from many smart and influential people. Ben Lawsky quit his job as the superintendent of financial services for New York State to build an advisory company in this space. He told us, “In five to ten years, the financial system may be unrecognizable . . . and I want to be part of the change.”6 Blythe Masters, formerly chief financial officer and head of Global Commodities at JP Morgan’s investment bank, launched a blockchain-focused technology start-up to transform the industry. The cover of the October 2015 Bloomberg Markets featured Masters with the headline “It’s All About the Blockchain.” Likewise, The Economist ran an October 2015 cover story, “The Trust Machine,” which argued that “the technology behind bitcoin could change how the economy works.”7 To The Economist, blockchain technology is “the great chain of being sure about things.” Banks everywhere are scrambling top-level teams to investigate opportunities, some of these with dozens of crackerjack technologists. Bankers love the idea of secure, frictionless, and instant transactions, but some flinch at the idea of openness, decentralization, and new forms of currency. The financial services industry has already rebranded and privatized blockchain technology, referring to it as distributed ledger technology, in an attempt to reconcile the best of bitcoin—security, speed, and cost—with an entirely closed system that requires a bank or financial institution’s permission to use. To them, blockchains are more reliable databases than what they already have, databases that enable key stakeholders— buyers, sellers, custodians, and regulators—to keep shared, indelible records, thereby reducing cost, mitigating settlement risk, and eliminating central points of failure.

Investing in blockchain start-ups is taking off, as did investing in dot-coms in the 1990s. Venture capitalists are showing enthusiasm at a level that would make a 1990s dot-com investor

blush. In 2014 and 2015 alone, more than $1 billion of venture capital flooded into the emerging blockchain ecosystem, and the rate of investment is almost doubling annually.8 “We’re quite confident,” said Marc Andreessen in an interview with The Washington Post, “that when we’re sitting here in 20 years, we’ll be talking about [blockchain technology] the way we talk about the Internet today.”9

Regulators have also snapped to attention, establishing task forces to explore what kind of legislation, if any, makes sense. Authoritarian governments like Russia’s have banned or severely limited the use of bitcoin, as have democratic states that should know better, like Argentina, given its history of currency crises. More thoughtful governments in the West are investing considerably in understanding how the new technology could transform not only central banking and the nature of money, but also government operations and the nature of democracy. Carolyn Wilkins, the senior deputy governor of the Bank of Canada, believes it’s time for central banks everywhere to seriously study the implications of moving entire national currency systems to digital money. The Bank of England’s top economist, Andrew Haldane, has proposed a national digital currency for the United Kingdom.10

These are heady times. To be sure, the growing throng of enthusiasts has its share of opportunists, speculators, and criminals. The first tale most people hear about digital currencies is the bankruptcy of the Mt. Gox exchange or the conviction of Ross William Ulbricht, founder of the Silk Road darknet market seized by the Federal Bureau of Investigation for trafficking illegal drugs, child pornography, and weapons using the bitcoin blockchain as a payment system. Bitcoin’s price has fluctuated drastically, and the ownership of bitcoins is still concentrated. A 2013 study showed that 937 people owned half of all bitcoin, although that is changing today.11

How do we get from porn and Ponzi schemes to prosperity? To begin, it’s not bitcoin, the still speculative asset, that should interest you, unless you’re a trader. This book is about something bigger than the asset. It’s about the power and potential of the underlying technological platform.
