If you can, use a password generator to create a completely random password that is at least 12 characters in length. Remember: bitcoin is money and can be instantly moved anywhere in the world. If it is not well protected, it can be easily stolen. Once Alice has downloaded and installed the Multibit application, she runs it and is greeted by a Welcome screen, as shown in Figure Multibit automatically creates a wallet and a new bitcoin address for Alice, which Alice can see by clicking the Request tab shown in Figure Like an email address, Alice can share this address and anyone can use it to send money directly to her new wallet.

The QR code is the black-and-white square on the right side of the window. Alice can copy the bitcoin address or the QR code onto her clipboard by clicking the copy button adjacent to each of them. Clicking the QR code itself will magnify it, so that it can be easily scanned by a smartphone camera.

Alice can also print the QR code as a way to easily give her address to others without them having to type the long string of letters and numbers. Bitcoin addresses start with the digit 1 or 3. Like email addresses, they can be shared with other bitcoin users who can use them to send bitcoin directly to your wallet. Unlike email addresses, you can create new addresses as often as you like, all of which will direct funds to your wallet.

A wallet is simply a collection of addresses and the keys that unlock the funds within. You can increase your privacy by using a different address for every transaction. There is practically no limit to the number of addresses a user can create. It is not possible to buy bitcoins at a bank or foreign exchange kiosks at this time.

As of , it is still quite difficult to acquire bitcoins in most countries. There are a number of specialized currency exchanges where you can buy and sell bitcoin in exchange for a local currency. These operate as web-based currency markets and include:. Cryptocurrency exchanges such as these operate at the intersection of national currencies and cryptocurrencies.

As such, they are subject to national and international regulations, and are often specific to a single country or economic area and specialize in the national currencies of that area. Your choice of currency exchange will be specific to the national currency you use and limited to the exchanges that operate within the legal jurisdiction of your country.

Similar to opening a bank account, it takes several days or weeks to set up the necessary accounts with these services because they require various forms of identification to comply with KYC know your customer and AML anti-money laundering banking regulations. Once you have an account on a bitcoin exchange, you can then buy or sell bitcoins quickly just as you could with foreign currency with a brokerage account.

You can find a more complete list at bitcoin charts , a site that offers price quotes and other market data across many dozens of currency exchanges. Alice was introduced to bitcoin by a friend and so she has an easy way of getting her first bitcoins while she waits for her account on a California currency market to be verified and activated.

Alice has created her bitcoin wallet and she is now ready to receive funds. Her wallet application randomly generated a private key described in more detail in Private Keys together with its corresponding bitcoin address. Her bitcoin address is simply a number that corresponds to a key that she can use to control access to the funds.

There is no account or association between that address and an account. Once it has been associated with a transaction, it becomes part of the known addresses in the network and Alice can check its balance on the public ledger. Alice meets her friend Joe, who introduced her to bitcoin, at a local restaurant so they can exchange some US dollars and put some bitcoins into her account.

She has brought a printout of her address and the QR code as displayed in her bitcoin wallet. There is nothing sensitive, from a security perspective, about the bitcoin address. It can be posted anywhere without risking the security of her account. Alice wants to convert just 10 US dollars into bitcoin, so as not to risk too much money on this new technology.

Next, Joe has to figure out the exchange rate so that he can give the correct amount of bitcoin to Alice. There are hundreds of applications and websites that can provide the current market rate. Here are some of the most popular:. Using one of the applications or websites just listed, Joe determines the price of bitcoin to be approximately US dollars per bitcoin. At that rate he should give Alice 0. For example, if using the Blockchain mobile wallet on an Android phone, he would see a screen requesting two inputs, as shown in Figure In the input field for the bitcoin address, there is a small icon that looks like a QR code.

The mobile wallet application fills in the bitcoin address and Joe can check that it scanned correctly by comparing a few digits from the address with the address printed by Alice. Joe then enters the bitcoin value for the transaction, 0. He carefully checks to make sure he has entered the correct amount, because he is about to transmit money and any mistake could be costly.

Finally, he presses Send to transmit the transaction. As the transaction is transmitted via the peer-to-peer protocol, it quickly propagates across the bitcoin network. If Alice has a smartphone or laptop with her, she will also be able to see the transaction.

The bitcoin ledger—a constantly growing file that records every bitcoin transaction that has ever occurred—is public, meaning that all she has to do is look up her own address and see if any funds have been sent to it. She can do this quite easily at the blockchain. The website will show her a page listing all the transactions to and from that address. If Alice is watching that page, it will update to show a new transaction transferring 0.

Alice is now the proud owner of 0. In the next chapter we will look at her first purchase with bitcoin, and examine the underlying transaction and propagation technologies in more detail. Skip to main content. Start your free trial.

Getting Started. This is similar to a standalone email server, in that it handles all aspects of the protocol without relying on any other servers or third-party services. The light client does not store a full copy of all transactions and therefore must trust the third-party servers for transaction validation.

While many books explain the how of bitcoin, The Internet of Money delves into the why of bitcoin.

Acclaimed information-security expert and author of Mastering Bitcoin, Andreas M. Antonopoulos examines and contextualizes the significance of bitcoin through a series of essays spanning the exhilarating maturation of this technology. Bitcoin, a technological breakthrough quietly introduced to the world in , is transforming much more than finance. Bitcoin is disrupting antiquated industries to bring financial independence to billions worldwide.

In this book, Andreas explains why bitcoin is a financial and technological evolution with potential far exceeding the label -digital currency. As the internet has essentially transformed how people around the world interact and has permanently impacted our lives in ways we never could have imagined, bitcoin--the internet of money--is fundamentally changing our approach to solving social, political, and economic problems through decentralized technology.

Despite the emergence of an interconnected global society and economy through the decades-long expansion of the internet, the trajectory of these bureaucratic policies foreshadows dire consequences for financial inclusion and independence. Andreas contextualizes the significance of Bitcoin and open blockchains amid these socio-political and economic shifts: What if money could be created without an authority?

Are corporate coins the first step towards techno neo-feudalism? Is the real "darknet" run by state intelligence agencies? What if everyone could have a Swiss bank in their pocket? Can we build digital communities resistant to gentrification?

In , Andreas M. The Internet of Money offered something that was desperately needed: an explanation of the philosophy, economics, politics, and poetics behind this technology. Make this book part of your collection and see why the internet of money will continue to transform the world and the internet itself.

Not supported by any government or central bank, completely electronic, Bitcoin is a virtual currency based on advanced cryptographic systems. The Nakamoto persona, which may represent an individual or a group, exists only in the online publications that introduced and explained Bitcoin during its earliest days. Beginning on November 1st with the publication of the seminal paper describing Bitcoin, this public life ends at about the time PC World speculated as to a possible link between Bitcoin and WikiLeaks, the infamous website that publishes leaked classified materials.

Was there a connection? You be the judge. Want to learn more about Bitcoin? Go directly to the source - the writings of the creator himself, Satoshi Nakamoto! Ten years later, and against all odds, this upstart autonomous decentralized software offers an unstoppable and globally-accessible hard money alternative to modern central banks.

The Bitcoin Standard analyzes the historical context to the rise of Bitcoin, the economic properties that have allowed it to grow quickly, and its likely economic, political, and social implications. While Bitcoin is a new invention of the digital age, the problem it purports to solve is as old as human society itself: transferring value across time and space.

Ammous takes the reader on an engaging journey through the history of technologies performing the functions of money, from primitive systems of trading limestones and seashells, to metals, coins, the gold standard, and modern government debt. Exploring what gave these technologies their monetary role, and how most lost it, provides the reader with a good idea of what makes for sound money, and sets the stage for an economic discussion of its consequences for individual and societal future-orientation, capital accumulation, trade, peace, culture, and art.

Compellingly, Ammous shows that it is no coincidence that the loftiest achievements of humanity have come in societies enjoying the benefits of sound monetary regimes, nor is it coincidental that monetary collapse has usually accompanied civilizational collapse.

With this background in place, the book moves on to explain the operation of Bitcoin in a functional and intuitive way. Bitcoin is a decentralized, distributed piece of software that converts electricity and processing power into indisputably accurate records, thus allowing its users to utilize the Internet to perform the traditional functions of money without having to rely on, or trust, any authorities or infrastructure in the physical world.

Bitcoin is thus best understood as the first successfully implemented form of digital cash and digital hard money. As it challenges the most sacred of government monopolies, Bitcoin shifts the pendulum of sovereignty away from governments in favor of individuals, offering us the tantalizing possibility of a world where money is fully extricated from politics and unrestrained by borders.

The final chapter of the book explores some of the most common questions surrounding Bitcoin: Is Bitcoin mining a waste of energy? Is Bitcoin for criminals? Who controls Bitcoin, and can they change it if they please? How can Bitcoin be killed?
