What applications can we build using Bitcoin as a platform? If we were designing a new cryptocurrency today, what would we change? What might the future hold? The online supplementary materials for this book include a series of homework questions to help you understand each chapter at a deeper level.

Most of the material of this book is also available as a series of video lectures on Coursera. You should also supplement your learning with information you can find online, including the Bitcoin wiki, forums, and research papers, and by interacting with your peers and the Bitcoin community. The path to Bitcoin is littered with the corpses of failed attempts.

Some are academic proposals that have been widely cited, while others are actual systems that were deployed and tested. And PayPal survived only because it quickly pivoted away from its original idea of cryptographic payments on handheld devices! Where do the ideas in Bitcoin come from? Why do some technologies survive while many others die?

What does it take for complex technical innovations to be successfully commercialized? If you imagine a world without governments or currency, one system that could still work for acquiring goods is barter. Suppose Alice wants a tool, and Bob wants medicine. If each of them happen to have what the other person needs, then they can swap and both satisfy their needs.

He wants medicine instead. The drawback, of course, is coordination—arranging a group of people, whose needs and wants align, in the same place at the same time. Two systems emerged to solve coordination: credit and cash. In a credit-based system, Alice and Bob would be able to trade with each other in the example above. In other words, Alice has a debt that she needs to settle with Bob some time in the future. In contrast, in a cash-based system, Alice would buy the tool from Bob.

Later, she might sell her food to Carol, and Carol can sell her medicine to Bob, completing the cycle. These trades can happen in any order, provided that the buyer in each transaction has cash on hand. Neither system is clearly superior. A cash-based system needs to be bootstrapped with some initial allocation of cash, without which no trades can occur. Cash also allows us to be precise about how much something is worth.

Cash lets us use numbers to talk about value. These ideas come up in many contexts, especially in online systems, where users trade virtual goods of some kind. For example, peer-to-peer file-sharing networks must deal with the problem of freeloaders, that is, users who download files without sharing in turn.

While swapping files might work, there is also the issue of coordination: finding the perfect person who has exactly the file you want and wants exactly the file you have. In projects like MojoNation and academic proposals like Karma, users are given some initial allocation of virtual cash that they must spend to receive a file and earn when they send a copy of a file to another user.

While MojoNation did not survive long enough to implement such an exchange, it became the intellectual ancestor of some protocols used today: BitTorrent and Tahoe-LAFS. Credit and cash are fundamental ideas, to the point that we can sort the multitude of electronic payment methods into two piles. Credit card transactions are the dominant payment method used on the web today.

You type in your credit card details, you send it to Amazon, and then Amazon takes these credit card details and talks to a financial system involving processors, banks, credit card companies, and other intermediaries. In contrast, if you use something like PayPal, what you see is an intermediary architecture.

A company sits between you and the seller, so you send your credit card details to this intermediary, which approves the transaction and notifies the seller. The intermediary will settle its balance with the seller at the end of each day. You might not even have to give the seller your identity, which would improve your privacy as well. The downside is that you lose the simplicity of interacting directly with the seller.

Both you and the seller might have to have an account with the same intermediary. But in the s, the web was new, standards for protocol-level encryption were just emerging, and these concerns made consumers deeply uncertain and hesitant. In particular, it was considered crazy to hand over your credit card details to online vendors of unknown repute over an insecure channel. This environment generated a lot of interest in the intermediary architecture.

A company called FirstVirtual was an early payment intermediary, founded in Incidentally, they were one of the first companies to set up a purely virtual office with employees spread across the country and communicating over the Internet—hence the name. If you wanted to buy something from a seller, the seller would contact FirstVirtual with the details of the requested payment, FirstVirtual would confirm these details with you, and if you approved, your credit card would be billed.

But two details are interesting. First, all of this communication happened over email; web browsers back in the day were just beginning to universally support encryption protocols like HTTPS, and the multiparty nature of payment protocol added other complexities.

Second, the customer would have 90 days to dispute the charge, and the merchant would receive the money only after those 3 months! If that happens, the merchant will have to return the payment to the credit card company.

SET also avoids the need for customers to send credit card information to merchants, but it additionally avoids the user having to enroll with the intermediary. In SET, when you are ready to make a purchase, your browser passes your view of the transaction details to a shopping application on your computer. The application encrypts it together with your credit card details in such a way that only the intermediary can decrypt it, and no one else can including the seller.

The seller blindly forwards the encrypted data to the intermediary—along with their own view of the transaction details. It was an umbrella specification that unified several existing proposals. It was an interesting company in many ways. In addition to credit card payment processing, they had a digital cash product called CyberCoin.

This was a micropayment system—intended for small payments, such as paying a few cents to read an online newspaper article. Yet, amusingly, they were able to get U. Back when CyberCash operated, there was a misguided—and now abandoned—U. However, CyberCash was able to get a special exemption for their software from the Department of State. Finally, CyberCash has the dubious distinction of being one of the few companies affected by the Y2K bug—it caused their payment processing software to double-bill some customers.

They later went bankrupt in Their intellectual property was acquired by Verisign, which then turned around and sold it to PayPal, where it lives today. The fundamental problem has to do with certificates. A certificate is a way to securely associate a cryptographic identity, that is, a public key, with a real-life identity. Putting security before usability, CyberCash and SET decided that not only would processors and merchants in their system have to get certificates, but all users also would have to get one as well.

Obtaining a certificate is about as pleasant as doing your taxes, so the system was a disaster. Over the decades, mainstream users have given a firm and collective no to any system that requires end-user certificates, and such proposals have now been relegated to academic papers.

Bitcoin deftly sidesteps this hairy problem by avoiding real-life identities altogether. In Bitcoin, public keys themselves are the identities by which users are known, as discussed in Chapter 1. In fact, the Consortium had a very general proposal for how you might extend the protocol, and one of the use cases that they had was handling payments.

This never happened—the whole extension framework was never deployed in any browsers. In , almost two decades later, the Consortium announced that it wanted to take another crack at it, and that Bitcoin would be part of that standardization this time around. I compared cash and credit earlier, and noted that a cash system needs to be bootstrapped, but the benefit is that it avoids the possibility of a buyer defaulting on her debt.

Cash offers two additional advantages. The first is better anonymity. Since your credit card is issued in your name, the bank can track all your spending. Bitcoin is not anonymous to the same level as cash is. Chapter 6 gets into the messy but fascinating details behind Bitcoin anonymity.

Chapter 3 looks at tricks like green addresses and micropayments, which allow offline payments in certain situations or under certain assumptions. The earliest ideas about applying cryptography to cash came from David Chaum in Consider this concept by means of a physical analogy.

In fact, banknotes themselves got their start as promissory notes issued by commercial banks. I can do the same thing electronically with digital signatures, but that runs into the annoying double-spending problem—if you receive a piece of data representing a unit of virtual cash, you can make two or more copies of it and pass it on to different people.

Can we solve double spending in this world? When you receive such a note from someone, you check my signature, but you also call me on the phone to ask whether a note with that serial number has already been spent. This works. He figured out how to both keep the system anonymous and prevent double spending by inventing the digital equivalent of the following procedure: when I issue a new note to you, you pick the serial number. This is called a blind signature in cryptography.

This was the first serious digital cash proposal. It works, but it still requires a server run by a central authority, such as a bank, and for everyone to trust that entity. Moreover, every transaction needs the participation of this server to be completed.

If the server goes down temporarily, payments grind to a halt. A few years later, in , Chaum in collaboration with two other cryptographers, Amos Fiat and Moni Naor, proposed offline electronic cash. The clever idea is to stop worrying about preventing double spending and focus on detecting it, after the fact, when the merchant reconnects to the bank server.

The transaction processing happens later, when the airline is able to reconnect to the network. If you think about it, quite a bit of traditional finance is based on the idea of detecting an error or loss, followed by attempting to recover the money or punish the perpetrator. If you write someone a personal check, they have no guarantee that the money is actually in your account, but they can come after you if the check bounces.

Conceivably, if an offline electronic cash system were widely adopted, the legal system would come to recognize double spending as a crime. At a high level, what it achieved was this: every digital coin issued to you encodes your identity, but in such a way that no one except you—not even the bank—can decode it. But if you ever double spend a coin, eventually both recipients will go to the bank to redeem their notes, and when they do this, the bank can put the two pieces of information together to decode your identity completely, with an overwhelmingly high probability.

You might wonder whether someone can frame you as a double spender in this system. Suppose you spend a coin with me, and then I turn around and try to double spend it without redeeming it with the bank and getting a new coin with my identity encoded. Over the years, many cryptographers have looked at this construction and improved it in various ways. But a paper by Tatsuaki Okamoto and Kazuo Ohta uses Merkle trees to create a system that does allow you to subdivide your coins.

The Chaum-Fiat-Naor scheme also leaves a lot of room for improvements in efficiency. In particular, the application of something called zero-knowledge proofs to this scheme most notably by Stefan Brands in the s, and Jan Camenisch, Susan Hohenberger, and Anna Lysyanskaya in was very fruitful—zero-knowledge proofs have also been applied to Bitcoin, as discussed in Chapter 6.

But back to Chaum: he took his ideas and commercialized them. He formed a company in called DigiCash, probably the earliest company that tried to solve the problem of online payments. They had about a 5-year head start on other companies like FirstVirtual and CyberCash, just discussed. Some banks actually implemented it—a few in the United States and at least one in Finland.

This was in the s, long before Bitcoin, which might come as a surprise to some Bitcoin enthusiasts who view banks as tech-phobic, anti-innovative behemoths. That would then open a reverse web connection back to your computer. That means your computer had to have the ability to accept incoming connections and act as a server. Chaum took out several patents on DigiCash technology, in particular on the blind-signature scheme that it used.

His action was controversial, and it stopped other people from developing ecash systems that used the same protocol. But a group of cryptographers who hung out on what was called the cypherpunks mailing list wanted an alternative. Cypherpunks was the predecessor to the mailing list where Satoshi Nakamoto would later announce Bitcoin to the world, and this is no coincidence. The cypherpunk movement and the roots of Bitcoin are discussed in Chapter 7.

The cypherpunk cryptographers implemented a version of ecash called MagicMoney. It did violate the patents, but was billed as being only for experimental use. It was a fun piece of software to play with. The interface was all text based. You could send transactions by email. You would just copy and paste the transactions into your email and send it to another user. Lucre tries to replace the blind-signature scheme in ecash with a nonpatent-encumbered alternative, and the rest of the system is largely the same.

Lucre tries to replace the blind-signature scheme in ecash with a nonpatent-encumbered alternative, and the rest of the system is largely the same. Yet another proposal, by Ian Goldberg, tried to fix the problem of not being able to split your coins to make change. But notice that this practice introduces an anonymity problem.

So Goldberg came up with a proposal using different types of coins that would allow these transactions to occur, allow you to get change back, and still preserve your anonymity. Why did DigiCash fail? The main problem was that it was hard to persuade banks and merchants to adopt it. It was really centered on the user-to-merchant transaction. So at the end of the day, DigiCash lost, and the credit card companies won.

As a side note, Bitcoin allows user-to-merchant and user-to-user transactions. There was something to do with your bitcoins right from the beginning: send them to other users, while the community tried to drum up support for Bitcoin and get merchants to accept it. In the later years of the company, DigiCash also experimented with tamper-resistant hardware to try to prevent double spending rather than just detecting it.

The device would keep track of your balance, which would decrease when you spent money and increase if you loaded the card with more money. These are some of the many questions this book answers.

Still, Gellasch said that "examination doesn't mean this is likely to be an enforcement case. Central banks remain skeptical of digital currencies, but analysts say the more real world uses appear for bitcoin, the more attractive it will prove as a long-term store of value.

It used to be negative reasons to buy , but suddenly there are positive reasons, and that's why you see bitcoin at new highs ," Mohamed El-Erian, chief economic advisor of Allianz, told CNBC. Tesla is the latest company to add bitcoin to its corporate treasury, following similar moves by Square, the payments company led by Twitter Inc chief Jack Dorsey and U. Apple Inc may be the next big company to enter the cryptocurrency market, both by allowing bitcoin to be exchanged on its Apple Wallet service and investing some of its own reserves in units of the cryptocurrency, said Mitch Steves, an analyst at RBC Capital Markets.

Tesla's move to put some of its corporate reserves in bitcoin may be a signal that it expects the cryptocurrency will emerge as another store of long-term value alongside the dollar and gold, said Graham Tanaka, president and chief investment officer of Tanaka Capital Management in New York. The automaker could be simply investing in Bitcoin because Musk has been known to have eclectic tastes. Musk launched a Tesla car into space to demonstrate the payload capabilities of his SpaceX company rockets.
