The Ethereum project understands the need to experiment, and when upgrades that are deemed important for the entire community become apparent, forking is seen as a better alternative than maintaining the concept of immutability. The Ethereum ecosystem has no qualms about forking its blockchain and gathering enough momentum for such changes to be successful. This attitude stands in stark contrast to other chains, like Bitcoin, where immutability is sacrosanct. Key Organizations in the Ethereum Ecosystem In the Ethereum ecosystem, multiple stakeholders and organizations support the vision that Ethereum is building, and each organization supports it from its own angle. The Ethereum Foundation As a leader in developing the roadmap and implementing further changes to the Ethereum platform, the Ethereum Foundation wields significant influence in the community.

Topics such as history, the definition of smart contracts, Ricardian contracts, Oracles, and the theoretical aspects of smart contracts are presented in this chapter. Chapter 10, Ethereum 101, introduces the design and architecture of the Ethereum blockchain in detail. It covers various technical concepts related to the Ethereum blockchain that explains the underlying principles, features, and components of this platform in depth. Chapter 11, Further Ethereum, continues the introduction of Ethereum from pervious chapter and covers topics related to Ethereum Virtual Machine, mining and supporting protocols for Ethereum. Chapter 12, Ethereum Development Environment, covers the topics related to setting up private networks for Ethereum smart contract development and programming.

The following table shows the list of Ethereum network with their network IDs. These network IDs are used to identify the network by Ethereum clients. Network name Network ID / Chain ID Ethereum mainnet 1 Morden 2 Ropsten 3 Rinkeby 4 Kovan 42 Ethereum Classic mainnet 61 More discussion on how to connect to testnet and how to set up private nets will be discussed in Chapter 12, Ethereum Development Environment. Components of the Ethereum ecosystem The Ethereum blockchain stack consists of various components. At the core, there is the Ethereum blockchain running on the peer-to-peer Ethereum network.

Formal specification of Ethereum has been described in the yellow paper which can be used to develop Ethereum implementations. We briefly touch on this subject here. The yellow paper The Ethereum yellow paper available at https://ethereum.github.io/yellowpaper/paper.pdf has been written by Dr. Gavin Wood, Founder, Ethereum & Parity (http://gavwood.com) and serves as a formal definition of the Ethereum protocol. Anyone can implement an Ethereum client by following the protocol specifications defined in the paper. While this paper can be somewhat challenging to read, especially for those who do not have a background in algebra or mathematics and are not familiar with mathematical notations, it contains a complete formal specification of Ethereum.

We will discuss blockchain and cryptocurrency in greater depth later on but for now will focus on a particular cryptocurrency with special relevance to DeFi. ETHEREUM AND DeFi Ethereum (ETH) is currently the second largest cryptocurrency by market cap ($260b). Vitalik Buterin introduced the idea in 2014, and Ethereum mined its first block in 2015. Ethereum is in some sense a logical extension of the applications of Bitcoin because it allows for smart contracts – which are code that lives on a blockchain, can control assets and data, and define interactions between the assets, data, and network participants. The capacity for smart contracts defines Ethereum as a smart contract platform. Ethereum and other smart contract platforms specifically gave rise to the decentralized application, or dApp.

Ethereum Request for Comments (ERC) related to defining a multitoken model, in which a contract can hold balances of a number of tokens, either fungible or non-fungible. Ethereum (ETH). In existence since 2015, second largest cryptocurrency or blockchain. Its native cryptocurrency is known as ether (ETH). Ethereum’s blockchain has the capability of running computer programs known as smart contracts. It is considered a distributed computational platform and sometimes referred to as the Ethereum Virtual Machine. Ethereum 2.0. A proposed improvement on the Ethereum blockchain that uses horizontal scaling, proof-of-stake consensus and other enhancements. Externally owned account (EOA). An Ethereum account controlled by a specific user.

For example, the largest cryptocommodity, Ethereum, is a decentralized world computer upon which globally accessible and uncensored applications can be built. It’s easy to appreciate the value of using such a computer, and therefore Ethereum provides a digitally tangible resource. Paying to use Ethereum’s world computer—also known as the Ethereum Virtual Machine (EVM)—is reminiscent of when schools and libraries had shared computers that students could use. One person could sit down and use a computer for a while before moving on, and then another person would come and use it. The Ethereum Virtual Machine operates somewhat similarly to a shared computer, except it is global in scale and more than one user can operate it at a time.

Like Argent, Metamask is a non-custodial wallet and it acts as both a wallet and an interaction bridge for the Ethereum network. You can store your Ethereum and ERC20 tokens on Metamask. Acting as an interaction bridge, Metamask enables you to use all Decentralized Applications (Dapps) that are hosted on the Ethereum Network. Without the use of an interaction bridge like MetaMask, your browser would not be able to access the Ethereum blockchain unless you were running a full Ethereum node and have the entire Ethereum blockchain of over 400GB downloaded on your computer. On a technical level, MetaMask does this by injecting a javascript library known as web3.js written by the core Ethereum developers into your browser’s page to enable you to easily interact with the Ethereum network.

While walking the dog, I listened to podcasts about Ethereum. When stealing any free time at work, I read about Ethereum. I rejiggered my Twitter feed to follow mostly Ethereum-related contacts. At my usual Friday night Twelve Step meeting, I pulled aside a shaken-looking newcomer. He also happened to be a software engineer. I didn’t ask him about his recovery. I asked him whether he’d heard of Ethereum. At night I played Ethereum-focused YouTube videos on the big screen. My favorites were from DevCon 1, which took place in London in November 2015—the first congregation of the embryonic Ethereum community. The event had a Woodstock feel.

What I thought would happen with Ethereum might just be happening. Ironically, the catalyst for this price rise was a sudden interest in Ethereum from corporations, governments, and other centralized institutions. Back in New York, they’d announced a new organization, spearheaded by Ethereum veterans, called the Enterprise Ethereum Alliance. There were thirty-five initial members, including some of the largest corporations in the world: Microsoft, J.P. Morgan, and British Petroleum. Over a day-long webcast conference at the J.P. Morgan office, they expressed their belief in Ethereum and sketched out working groups to aid development and interoperability with private chains.

In crypto, this was usually a sign that something batshit crazy was about to happen. In Taipei, on November 25, Vitalik gave a detailed lecture about the future of Ethereum. He laid out the road map for what he dubbed Ethereum 2.0 and explained how Ethereum would implement a theoretical scalability breakthrough called sharding and a new smart contract programming language called Viper. He also spoke at length about the eventual upgrade from Ethereum’s proof of work algorithm, which most blockchains, including Bitcoin, utilized. Ethereum was moving to proof of stake which required much less energy. It would enable real decentralized apps for the first time.

Spurning the hard fork, the splinter group continued to build on the original blockchain, calling it—and the digital currency associated with it—Ethereum Classic. Today, Ethereum and Ethereum Classic operate as separate realms, two versions of what was once one reality. Both are going strong. While the former is forty times more valuable—Ethereum was worth more than $45 billion in mid-2020—both are adding new blocks to their respective chains every fifteen seconds or so. The DAO debacle briefly damaged Ethereum’s credibility, but did little to halt its steady rise as the first serious challenger to bitcoin. The buzz over Vitalik’s creation came from the power of smart contracts, but Ethereum had a currency of its own called ether, which was mined and traded just like bitcoin.

This meant it was not just speculators investing in Ethereum, but many software developers who had to pay for it as part of their day-to-day business operations. Ethereum had become akin to a hot piece of real estate where anyone who wanted to run a store had to pay a small tax. The price began to shoot up like crazy. At the outset of 2016, Ethereum sold for 95 cents and by June the price hit $18. If bitcoin was digital gold, Ethereum was digital silver. Meanwhile, venture capitalists, including Coinbase board member Chris Dixon, had begun to take notice and rave about the potential of Ethereum to change the world. It was like the original 2013 bitcoin mania all over again but this time it was about something much bigger than digital money—Ethereum was a way to change business, the internet, and society itself.

Other cryptocurrencies had been hacked and hijacked. Ethereum wasn’t only hacked, but its ledger was tampered with on purpose. What’s more, buying and selling bitcoin had always been Coinbase’s bread and butter—straying from the company’s core mission to deal in a still-unproven alternative could bite them in the ass. Brian’s partner Fred Ehrsam didn’t see it that way. A trip to Shang-hai had convinced him that Ethereum and smart contracts were the future. Ethereum had momentum. It had technology that bitcoin lacked. And unlike bitcoin, Ethereum insiders weren’t consumed by civil war. “Ethereum’s core development team is healthy while bitcoin’s is dysfunctional,” he would write in a blog post, contrasting Vitalik’s take-charge ability to the leaderless and toxic state of bitcoin in the wake of the block-size debate.

And since Ethereum is more of a community of software engineers than of cryptocurrency investors, it was less contentious than Bitcoin’s struggle over hard-fork proposals. What’s more, it turned out that disgruntled Ethereum participants weren’t entirely powerless, either. A group decided to continue mining and trading the older, non-forked version of ether, with The DAO attacker’s coins still there in the transaction history. They called it Ethereum Classic, adopted the code ETC for its currency, and traded it alongside the forked Ethereum’s ETH ether. You now had two versions of Ethereum. This created much confusion and some interesting arbitrage opportunities—as well as some lessons for bitcoin traders when their own currency split two years later—but it can also be viewed as the actions of a dissenting group non-violently exercising their right to secede.

You have to use whatever resource you are given because you cannot code independently of these resources. Ethereum Ethereum is a known blockchain platform that is the most advanced for coding and processing smart contracts. You are given the liberty to code whatever you desire but would have to pay for computing power with “ETH” tokens. Smart contracts have no end to the number of industries they can influence from healthcare, real estate, and even the law. The list of its potentials goes on and on. Chapter 4: Ethereum and DeFi Let’s start by specifying that presently, most if not pretty much all of the DeFi projects are built on Ethereum. Ethereum is a decentralized blockchain that allows other decentralized blockchain applications (dApps) to be built on smart contracts, and some of these apps can have their exchangeable tokens.

However, the gas cost of using the contract is much higher. Ethereum provides a coder-friendly language for writing smart contracts Called “Solidity.” ● Solidity Solidity is an object-oriented coding language for writing smart contracts. The great thing about Ethereum is that smart contracts can be programmed in a relatively developer-friendly language. If you have experience with Python or JavaScript, you can find a smart contract framework to use with a familiar syntax. Smart contracts regulate the behavior of accounts in the Ethereum platform. Solidity is inspired by C++, Python, and JavaScript and is structured for the Ethereum Virtual Machines.

It is mainly used to perform smart contracts on various blockchain platforms such as Ethereum. It was developed by Christian Reitwissner, Alex Beregsazi, and several former Ethereum key contributors to enter smart contracts on blockchain platforms. The Solidity programming language is primarily intended for code development and implementation of the Ethereum virtual machine. Furthermore, smart contracts establish the rules and penalties surrounding an agreement in the same way that a conventional contract does, but it also enforces those obligations automatically. ● Vyper Vyper allows you to program on Ethereum, a blockchain-based virtual machine that permits smart contracts' design and execution without the need for centralized or trusted intermediaries.

– the community sponsored sending a physical Dogecoin on an Astrobotic commercial moon shot.293 It came out in May 2017 that the operator of the Dogecoin tipping bot on Reddit had stolen all the deposited Dogecoins two years earlier.294 Much sorry, many loss. Ethereum Ethereum was proposed by Vitalik Buterin (an early Bitcoiner and a co-founder of Bitcoin Magazine) and developed by Buterin, Gavin Wood, Jeffrey Wilcke and others. Its key innovation is that you can run smart contracts on a blockchain: programs that are triggered to run automatically in a given circumstance. If Bitcoin is like an Excel spreadsheet, then Ethereum is like a spreadsheet with macros. This new idea was interesting enough to quickly make Ethereum the second most popular cryptocurrency. Transactions and smart contract programs (which they call “dapps,” short for “distributed applications”) require gas (a certain amount of the currency token, ether, abbreviated ETH), which is paid to the miner whose computer runs the transaction or smart contract.

As at mid-2017 it’s running about 2-3 TPS, having rapidly risen over 2017;301 popular dapps already fill the blocks and clog the system for hours at a time, such as the Bancor and Status ICOs. The Ethereum community seems to have faith in the Ethereum Foundation, so a fix is more likely to be accepted without a Bitcoin-style community civil war; and backward-compatibility-breaking changes in Ethereum are a regular occurrence and are mostly managed without controversy. The developers have always stated that Ethereum is explicitly experimental and unfinished (and never mind the hundreds of millions of dollars in ether swilling around in it), and that the promised fancy functionality will need years of work.302 They occasionally boggle at people treating it as much more of a finished product than they do.303 Ethereum advocates talk up corporate adoption by Microsoft and other companies – it’s a popular choice of platform for business blockchain trials, and its smart contract functionality is reused by a lot of other blockchain software – but this is adoption of the software to run separate in-house blockchains, not adoption of the public Ethereum chain and currency.

In computer science terms, this approach could only have worked by first solving the halting problem: you would need to be able to determine the outcome of any possible Ethereum program without actually running it and observing the result.361) The DAO was shut down soon after, and on 20 July the Ethereum Foundation – several of whose principals were curators of The DAO362 and/or heavily invested in it – changed how the actual code of Ethereum interpreted their blockchain (the “immutable” ledger) so as to wind back the hack and take back their money. The blockchain was “immutable,” so they changed how it was interpreted. The “impossible” bailout had happened. This illustrated the final major problem with smart contracts: CODE IS LAW until the whales are in danger of losing money. Ethereum promptly split into two separate blockchains, each with its own currency – Ethereum (ETH), the wound-back version, supported by the Ethereum Foundation, and Ethereum Classic (ETC), the original code and blockchain – because all this was too greedy even for crypto fans to put up with.

Rather than being a blockchain, or a protocol running over a blockchain, or a metaprotocol running over a protocol like other projects, Ethereum is a fundamental underlying infrastructure platform that can run all blockchains and protocols, rather like a unified universal development platform. Each full node in the Ethereum network runs the Ethereum Virtual Machine for seamless distributed program (smart contract) execution. Ethereum is the underlying blockchain-agnostic, protocol-agnostic platform for application development to write smart contracts that can call multiple other blockchains, protocols, and cryptocurrencies. Ethereum has its own distributed ecosystem, which is envisioned to include file serving, messaging, and reputation vouching. The first component is Swarm (“Ethereum-Swarm,” not to be confused with the crowdfunding site Swarm) as a decentralized file-serving method.

In 2017, it survived a possibly life-threatening crisis when one of the projects using its blockchain, the Distributed Autonomous Corporation, was hacked for some $150 million worth of ether. (Two breakdowns involving Ethereum-related “wallets” followed). Under Buterin’s sure-footed leadership, much of the damage was contained, but at the cost entering the chain forcibly and reversing the offending transactions, resulting in a “hard fork” and the rise of a rival chain called Ethereum Classic, led by the former Ethereum coder Hoskinson. This incident was not the result of flaws in the Ethereum blockchain itself, but that didn’t matter. As the ruler of the chain, Buterin could not escape the need to intervene. Proponents of Ethereum Classic contend that this arbitrary action undermined the immutability of the database and the principle of decentralization that is the heart of the blockchain.

But his grandiosity and apparent lack of focus defied all the rules of successful enterprise. They decided to support him anyway. In November 2013, Buterin wrote the Ethereum white paper, and on June 5, 2014, Peter Thiel announced a new group of twenty Thiel Fellows, which included Buterin. A year later, Ethereum went live, with the announcement, “What bitcoin does for payments, Ethereum does for anything that can be programmed.” It was another step in the decentralization of the Internet. Just as Ethereum was entering the larger world, in July 2015, Strachman and Gibson were leaving the Thiel Fellowship to start a new but related project, the 1517 Fund, which would invest in Thiel Fellows and other high school and college-aged company founders.

Proponents of Ethereum Classic contend that this arbitrary action undermined the immutability of the database and the principle of decentralization that is the heart of the blockchain. Ethereum Classic has not yet had much influence. Hoskinson has gone on to form Cardano, attempting a blockchain that redresses all the flaws of bitcoin through rigorous functional software. Saifedean Ammous, the author of The Bitcoin Standard, contends: “The fact that Ethereum could be rolled back means that all blockchains smaller than Bitcoin’s are essentially centralized databases under the control of their operators.”5 The key difference between the bitcoin and Ethereum blockchains is that bitcoin focuses on security and simplicity while Ethereum focuses on capability and functionality.

That architecture drawing was later iterated upon, and appeared in one of Vitalik's blog posts, titled “On Silos.”2 Over the next several months, and up to this day, we became reverse mentors. He taught me a lot about blockchains, and I advised him on business matters and growing Ethereum. I may never comprehend a fraction of Vitalik's blockchain dreams on a given night, but one thing I am certain about, is that Vitalik Buterin is emerging as a savvy business person, following the ranks of other bright technologists, while continuing to lead the Ethereum core technology and its Foundation. I proceeded to write 50 blog posts on Bitcoin, blockchains, and Ethereum, and immersed myself with global creators, innovators, pioneers, leaders, entrepreneurs, startups, enterprise executives and practitioners who were at the leading edges of blockchain technology and its implementation.

I hope that readers will find The Business Blockchain as useful as I found it exhilarating to write.

CHAPTER 4 RE-ARCHITECTING THE FIRM: THE CORE AND THE EDGES BUILDING CONSENSYS July 30, 2015, was a big day for a global group of coders, investors, entrepreneurs, and corporate strategists who think that Ethereum is the next big thing—not just for business, but possibly for civilization. Ethereum, the blockchain platform eighteen months in the making, went live. We witnessed the launch firsthand in the Brooklyn office of Consensus Systems (ConsenSys), one of the first Ethereum software development companies. Around 11:45 a.m., there were high fives all around as the Ethereum network created its “genesis block,” after which a frenzy of miners raced to win the first block of ether, Ethereum’s currency. The day was eerily suspenseful. A massive thunderstorm broke over the East River, triggering loud and random emergency flood warnings on everyone’s smart phones.

A massive thunderstorm broke over the East River, triggering loud and random emergency flood warnings on everyone’s smart phones. According to its Web site, Ethereum is a platform that runs decentralized applications, namely smart contracts, “exactly as programmed without any possibility of downtime, censorship, fraud, or third party interference.” Ethereum is like bitcoin in that its ether motivates a network of peers to validate transactions, secure the network, and achieve consensus about what exists and what has occurred. But unlike bitcoin it contains some powerful tools to help developers and others create software services ranging from decentralized games to stock exchanges. Ethereum was conceived in 2013 by then-nineteen-year-old Vitalik Buterin, a Canadian of Russian descent.

If Deleuze and Guattari held that the fundamental task of a philosopher is the creation of new concepts, indeed, it’s not entirely ridiculous to think of Buterin’s work in this way.3 However we may evaluate them practically or ethically, the explosion of post-Satoshi development has populated the world with new and challenging objects of thought, and the community around Ethereum has been especially fruitful in this regard. Ethereum does offer its own token of value—a cryptocurrency called Ether4—and people do mine and trade in Ether directly, just as they might Bitcoin. But what the network does with it is quite a bit subtler and more interesting than the mere transfer of value between human beings. Buterin had conceived Ethereum from the outset as a single, massively distributed computing engine sprawled across the global network, in which all processing is paid for in increments of Ether.

But however much one or another of these propositions might appeal to some pie-slice of its target audience, none of them is quite as compelling to the community gathered around Ethereum as its power to act conditionally. This ability to trigger events should certain contingencies arise is something the Bitcoin blockchain could not do, and Buterin had designed it into his creation from the start. You can store data of any nature on the Ethereum blockchain, and it will be validated, agreed upon and permanently accessible to anyone who asks for it, just as records of Bitcoin transactions are accessible to anyone querying the Bitcoin blockchain. But you can also perform logical operations with Ethereum—any operation that a general-purpose computer would be capable of handling.

What has really made headlines, however, is that major technology companies, banks and financial institutions around the world have announced they are working on projects using Ethereum. Details are thin at this point, but UBS and Barclays have both announced an interest in Ethereum, and Microsoft is offering Ethereum in some capacity on its cloud computing service, making it easy for developers to create Ethereum apps. This support from the outside world is unheard of for cryptocurrencies not named Bitcoin and that, more than anything, is the biggest sign that Ethereum will have some success going forward. It has a long way to go before it becomes the next Bitcoin, which is still light-years ahead in support from both inside and outside the community.

It has a long road ahead of it, because as it turns out, even useless scam coins die hard. Ethereum Algorithm: Ethash Mining Type: Proof-of-Work with plans to switch to new proof-of-stake method Block Time: Around 20 seconds Block Reward: 5 Ether per block Maximum Blocksize: 1MB Total Number: No limit I conclude with perhaps the most exciting cryptocurrency since Bitcoin. Ethereum is more than a coin, describing itself thus: “Ethereum is a decentralized platform that runs smart contracts: applications that run exactly as programmed without any possibility of downtime, censorship, fraud or third party interference. Ethereum is how the Internet was supposed to work.”

If no one is using an asset exchange or if only scammers are using it, it is not very useful. The support for Ethereum from the outside world is, to me, a sign that the altcoin world is finally solidifying. Most altcoins will fail; in fact, most already have. There are simply too many of them. But a few might find niches and one or two might even be a part of our mainstream economy one day. I would suggest you don’t invest anything more than pocket change into an altcoin with the possible exception of Ethereum. But this doesn’t mean altcoins aren’t worth paying attention to. Anonymous coins, asset-creating Bitcoin 2.0 coins, and intriguing technologies such as Ethereum will all play some role in our future economy. 1 Farivar, Cyrus.

Proof of Stake versus Proof of Work There are variants of Proof of Work that operate slightly differently. For more comprehensive (and technical) overviews of these and alternative consensus protocols, see Bano et al. (2019) and Ismail and Materwala (2019). Descriptions of the technical aspects of Ethereum can be found at https://ethereum.org/learn/#improving-ethereums-scalability. The first building block for the Ethereum upgrade, the Beacon Chain, went live in December 2020. See https://ethereum.org/en/eth2. Some back-of-the-envelope calculations (by a company whose blockchain uses Proof of Stake) comparing energy consumption under the Proof of Work and Proof of Stake consensus protocols are reported in ODIN Blockchain, “Going Green: Energy Consumption Evaluation Part 2: Proof of Stake Consensus Algorithms,” Medium, November 12, 2019, https://medium.com/@odinblockchain/going-green-energy-consumption-evaluation-part-2-proof-of-stake-consensus-algorithms-8ce613f1179b.

Smart Contracts Over time, other virtual currencies added significant new features that updated the blockchain concept so it could handle a wider variety of information. The most valuable virtual currency other than Bitcoin is Ether, which runs on the Ethereum blockchain. In addition to recording virtual currency transactions, the Ethereum blockchain can record and execute automated programs. It is possible, for example, to create a program on the Ethereum blockchain that will move Ether between wallets only after a specific event. This functionality has turned out to have useful applications. Smart contracts are self-executing computer programs that perform predefined tasks based on a predetermined set of criteria or conditions.

However, the community governs these changes and must therefore be convinced that any revisions are to their collective benefit.* Developers and users need not worry that, as an example, “Ethereum Corp” might suddenly increase Ethereum transaction fees or impose new ones, deny an emerging technology or standard, launch a first party service that competes with the most successful dapps, and so on. Ethereum’s trust­less and permissionless programming actually encourages developers to “compete” with its core functionality. Ethereum has its detractors, who level three primary criticisms: its processing fees are too high, its processing times are too long, and its programming language is too difficult.

Not long after Bitcoin emerged (its creator remains anonymous), two early users, Vitalik Buterin and Gavin Wood, began developing a new blockchain, Ethereum, which they described as a “decentralised mining network and software development platform rolled into one.”1 Like Bitcoin, Ethereum pays those operating its network through its own cryptocurrency, Ether. However, Buterin and Wood also established a programming language (Solidity) that enabled developers to build their own permissionless and trustless applications (called “dapps,” for decentralized apps), which could also issue their own cryptocurrency-like tokens to contributors. Ethereum, then, is a decentralized network that is programmed to automatically compensate its operators.

[DAOs have] the potential to change the way people buy things, build companies, share resources and run nonprofits.”11 At the same time, ConstitutionDAO also illuminated many of the problems with the Ethereum blockchain. For example, an estimated $1 million to $1.2 million was spent processing transactions to fund the DAO. Though this represented 2.1% of contributions—within the average range for traditional payment rails—the median contribution was estimated at $217, with nearly $50 spent in “gas.” In addition, the Ethereum blockchain cannot “waive” fees for reversing or refunding a transaction. As a result, these fees were effectively doubled as a result of the auction, as most contributors reclaimed their donations.

And the app catalogue is totally decentralized just like the network. So even we don’t control it – so we can’t take apps down or anything and the government can’t take apps down or something like that. So, that’s what we’re trying to do: mainstream this dis-intermediation technology’. The implications of Ethereum – if it takes off – are clearly enormous. For more information about Ethereum, visit ethereum.org. 10 Should You Buy In? You can’t stop things like Bitcoin. It’s like trying to stop gunpowder. It will be everywhere and the world will have to readjust. John McAfee, computer scientist, founder of McAfee Inc In the 1830s and 1840s a mania gripped the UK.

‘That is what we’re hoping to do.’ How Bitcoin is just the start of something much, much bigger Ethereum is probably the most talked-about development in cryptography at present. Some call it Bitcoin 2.0. It combines the decentralized mining system central to Bitcoin with a software development platform. Its founders say the potential applications are unlimited: from peer-to-peer betting, to financial derivatives, to identity and reputation systems, to insurance and legal contracts. Some say Satoshi Nakamoto may now even be working for Ethereum. Its former CEO is Charles Hoskinson. A bespectacled, bearded, extremely bright, friendly and fast-talking mathematician.

This is a system that would work just as well in Africa as it works in North America or Europe, which is a huge step forward for ecommerce and banking the unbanked. And that’s what gets me really excited about the technology and why I came into this space.’ So, what exactly is Ethereum? Everybody’s talking about it, but few seem to understand it. ‘Ethereum is really a continuation of what Satoshi Nakamoto was working on. He wanted to study two things when he released Bitcoin. He’d been working on it for quite some time. The first was this idea of a decentralized database secured by a proof-of-work consensus system, and the second thing was a transaction system – tokens.

In this case, it led to a ‘hard fork’ in the code. The purists branched off into Ethereum Classic, while the pragmatists adapted the code and recovered the funds. The recovered DAO did not live up to its expectations, however, and by the end of 2016 most major crypto exchanges had delisted its tokens from trading. Ethereum Classic still exists, but now ranks #41 on the list of cryptocurrencies, worth only 1 per cent of the value of Ethereum. While Ethereum’s coding language is specifically geared towards smart contracts, few smart contracts have been entered into thus far. But the Ethereum code seems to be quite handy for launching new crypto tokens, as many of the 5,500 cryptocurrencies (mostly ICOs) are built and executed on the Ethereum distributed computing platform.

Still, there are two important drawbacks that will have to be overcome if the technology is to go mainstream: it is expensive and it is a dream for crooks. Bitcoin payments are not free – in fact, compared with most other forms of payment, they can cost a lot. Each transaction involves a fee for the sender and mining costs. Ethereum/Ether With 11 per cent of the crypto market’s total value, Ethereum’s Ether is the next largest cryptocurrency after Bitcoin, and the prime example of a utility coin. Ethereum is a ‘distributed computing platform’ and a very different animal from Bitcoin. Its currency, Ether, is not used to pay for goods or services. Instead, it is used to buy computer time from participants. In exchange, these participants run code that you give them.

The crooks, perhaps sensitive to the fact that their business model rests on their reputation for responding to ransom payments, reportedly unlocked the systems. In Ethereum the contracts are submitted as code and automatically executed or enforced. This takes the thinking behind Bitcoin even further. Bitcoin aims to replace money and much of banking: there is no need to put our trust in institutions like (central) banks when we can trust code and cryptography instead. Ethereum would apply this not only to money and banks but to all contracts and intermediaries. Contracts and data are put on shared ledgers, where their integrity can be inspected and verified by a community of users or miners.

Tokens took off with the development of the ERC-20 standard back in 2015. ERC-20 defined a way of creating a standard form of token using ‘smart contracts’ on the Ethereum blockchain. Please note, once again, that smart contracts are not contracts at all because there is no possibility of uncertainty in their execution, and thus no compliance; strictly speaking, they are just automaticity created by the consensus-forming process. The inventor of Ethereum, Vitalik Buterin, says as much: ‘I now regret calling the objects in Ethereum “contracts” as you’re meant to think of them as arbitrary programs and not smart contracts specifically’ (DuPont and Maurer 2015).

There are many ways that this will be beneficial to society as a whole, not least because any Libra transactions will be placed on an immutable shared ledger. * * * 40 Hint: it is not transaction fees. 41 In Ethereum’s decentralized autonomous organization (DAO) case study, it was possible to write and deploy a smart contract that turned out to be exploitable by attackers. This is because Ethereum is a permissionless platform with no intrinsically defined ‘control layer’. 42 Note that, given my 5Cs taxonomy of the future of money in table 4, I would classify Libra as a community currency rather than a corporate currency.

DeFi start-ups are trying to build an interlocking financial system denominated in cryptocurrencies. They offer a wide array of lending and derivatives products, available globally, peer-to-peer and without any middlemen, but they have their own systemic risks. Their initiatives all rely on the protocols on which they are built, such as Ethereum, which has faced its own problems with scaling (remember CryptoKitties?). They are also tied to the cryptocurrencies that ‘fuel’ these protocols. If the underlying cryptocurrency layer does not work, the apps on it will also stop working. It is as simple as that. As we will see in part 3, DeFi could be a building block in a parallel financial system that some countries might find attractive.

The Nakamoto Institute’s withering assessment was that Ethereum was “doomed.” Its combination of poor programming and terms of use that essentially made this lousy programming legally binding spelled disaster. Believers in the dream of decentralizing all the things, however, weren’t yet ready to give up. In July of 2016, Vitalik Buterin, one of Ethereum’s cofounders and the author (at nineteen years old) of the influential 2013 “Ethereum White Paper,” announced a “hard fork” in the cryptocurrency and its blockchain. If a majority of participants in The DAO accepted this fork (which was embodied in a new version of the Ethereum software), all previous transactions that occurred within the decentralized autonomous organization would be essentially forgotten, and all involved ethers would be returned to their original owners.

The hard fork, many felt, did something much worse. It didn’t arbitrarily change the value of ethers; it actually changed who owned them. Some participants in the original DAO refused to go along with the hard fork, continued to use the original version of the distributed software, and named their system “Ethereum Classic.” As we write this in early 2017, Ethereum and Ethereum Classic continue to exist in parallel. Bitcoin’s Bitter End? Despite ample worldwide enthusiasm for them, Bitcoin and the blockchain have also experienced trouble. In January of 2016 Mike Hearn, who had been a prolific and respected contributor to programming for the blockchain, and who had believed in its promise so deeply that he had quit his job at Google to devote himself full-time to it, sold all his Bitcoins and walked away from the project.

In mid-2013, journalist Vitalik Buterin also got: Vitalik Buterin, interviewed by Michael J. Casey, January 26, 2014. Buterin first laid out his vision in a white paper: Vitalik Buterin, “Ethereum White Paper,” January 2014, https://www.ethereum.org/pdfs/EthereumWhitePaper.pdf. The team also planned a fund-raiser: Michael J. Casey, “BitBeat: Ethereum Presale Hits $12.7 Million Tally,” Wall Street Journal, MoneyBeat blog, http://blogs.wsj.com/moneybeat/2014/08/05/bitbeat-ethereum-presale-hits-12-7-million-tally/. Here, once again at the vanguard: “The Ripple Protocol: Executive Summary for Financial Institutions,” Ripple.com, https://ripple.com/files/ripple-FIs.pdf.

Sounding every bit the MBA-qualified financial engineer, Buterin rattles off concepts for apps that could run on Ethereum and help reinvent Wall Street: digital-currency-denominated derivative contracts through which traditional currencies and commodities trade as digital IOU tokens; Ethereum-based security offerings that function without a need for the underwriting and book-running services of an investment bank; decentralized algorithms to challenge the sinister “dark pool” investment vehicles and high-frequency trading machines with which hedge funds, investment banks, and Wall Street high rollers get an edge on the market. But he admits he’s just tossing out ideas. For now, Ethereum is an unproven project.

The solution he came up with quickly took the cryptocurrency world by storm: a completely redesigned, fully versatile, decentralized blockchain that could function as an open platform on which all manner of contracts and decentralized applications could be installed. He called it Ethereum. “We are hoping to be like the Android of cryptocurrency,” Buterin says, referring to the Google-designed mobile operating system that’s used by multiple models of smartphones and which had by 2014 inspired more than a million apps. “On Android you can install Google Maps, you can install Gmail, you can install whatever you want. That’s where we want cryptocurrency to go. Ethereum provides the base layer, and if you want to install a wallet, there’s an app for that; if you want to install a block explorer, you can design one; or a merchant payments solution or whatever.”

Kim’s Instagram post from June 2021 read as follows: ARE YOU GUYS INTO CRYPTO???? THIS IS NOT FINANCIAL ADVICE BUT SHARING WHAT MY FRIENDS JUST TOLD ME ABOUT THE ETHEREUM MAX TOKEN! A FEW MINUTES AGO ETHEREUM MAX BURNED 400 TRILLION TOKENS—LITERALLY 50% OF THEIR ADMIN WALLET, GIVING BACK TO THE ENTIRE E-MAX COMMUNITY. SWIPE UP TO JOIN THE E-MAX COMMUNITY. To borrow from the industry’s charming parlance, EthereumMax was a shitcoin. The hastily assembled crypto project seemed purposely designed to be confused with the second biggest cryptocurrency, Ethereum, even though the two were not related. Kim’s post, sent out to her then 251 million (!) followers, was an enormous publicity success for the obscure token.

Over the past year, also using leverage, Ahmed had ridden the crypto wave up, turning an initial stake of 1,250 Ethereum tokens into 3,300 that were eventually worth more than $13 million. (He said he started trading in 2017 with about $25,000.) Ahmed was betting that the crypto market would continue its overall rise, though he said he planned to cash out if the price of Ethereum reached $4,100. Like Kim, Ahmed expected some volatility along the way, but it was only on May 19, when Ethereum plunged dramatically alongside Bitcoin and other currencies, that Ahmed realized the gravity of his situation.

If you want to get somewhere else, you must run at least twice as fast as that!” That was the basic technological and philosophical framework for Bitcoin, the original cryptocurrency, from which all others sprang. Ethereum, the second largest cryptocurrency as of this writing, was launched in 2015. It offered an alternative open-source blockchain and became notable for offering what are called smart contracts: small computer programs that execute functions automatically on the Ethereum blockchain. A simple example might be to use smart contracts to replicate the escrow process. You could program a transaction that would go through only if two of the three parties said it should, like a buyer, a seller, and a trusted referee.

While this would be great for a new start‐up, it is anathema to a project that wants to demonstrate credible commitment to a fixed monetary policy. Should the teams behind any particular altcoin decide to change its monetary policy, it would be a relatively straightforward thing to achieve. Ethereum, for instance, does not yet have a clear vision of what it wants its monetary policy to be in the future, leaving the matter up to community discussion. While this may work wonders for the community spirit of Ethereum, it is no way to build a global hard money, which, to be fair, Ethereum does not claim to do. Whether it is because they are aware of this point, or to avoid run‐ins with political authority, or as a marketing gimmick, most altcoins do not market themselves as competitors to Bitcoin, but as performing tasks different to Bitcoin.

In the aftermath of the DAO hack, Ethereum developers created a new version of Ethereum where this inconvenient mistake never occurred. This re‐injection of subjective human management is at odds with the objective of making code into law, and questions the entire rationale of smart contracts. Ethereum is the second largest blockchain after Bitcoin in terms of its processing power, and while the Bitcoin blockchain cannot effectively be rolled back, that Ethereum can be rolled back means that all blockchains smaller than Bitcoin's are effectively centralized databases under the control of their operators. It turns out code is not really law, because the operators of these contracts can override what the contract executes.

This problem is more pronounced for digital currencies that begin with an Initial Coin Offering, which creates a highly visible group of developers communicating publicly with investors, making the entire project effectively a centralized project. The trials and tribulations of Ethereum, the largest coin in terms of market value after Bitcoin, illustrate this point vividly. The Decentralized Autonomous Organization (DAO) was the first implementation of smart contracts on the Ethereum network. After more than $150 million was invested in this smart contract, an attacker was able to execute the code in a way that diverted around one‐third of all the DAO's assets to his own account.

Buterin is a cofounder of Ethereum, the best-known project to generalize blockchain technology into applications that go beyond currency-like systems. Buterin (2014) describes DAOs “and their subclass, DACs,” as the “holy grail” of decentralized applications. A DAO “is an entity that lives on the internet and exists autonomously, but also heavily relies on hiring individuals to perform certain tasks that the automaton itself cannot do.”

197 The decision rules of The DAO required a majority vote, and the pragmatists won the day; they altered the code, unwound The DAO, and returned the ether to the majority of the token holders. The minority, however, held on to the original code, which they now labeled “Ethereum Classic” (ETC), a new digital asset, which competes with the adulterated original Ethereum (ETH).38 The DAO is a cautionary tale of coded determinism operating in an unpredictable world. It also is a good illustration of how codes evolve, whether they are legal or digital. The pragmatists among The DAO’s token holders decided to leave the final say about its fate in the hands of humans.

For a survey of the effects of formalizing property rights in the developing world in recent years, see Klaus Deininger, Land Policies for Growth and Poverty Reduction, World Bank Policy Research Reports (Washington, DC: World Bank, 2003). 29. The concept of the decentralized autonomous organization (DAO) is illustrated on the Ethereum website: https://www.ethereum.org/dao. For a useful account of The DAO’s brief existence, see Muhammed Izhar Mehar et al., “Understanding a Revolutionary and Flawed Grand Experiment in Blockchain: The DAO Attack,” available online at ssrn.com/abstract=3014782 (2017). 30. See the SEC’s press release of July 25, 2017, available online at https:// www.sec.gov/news/press-release/2017-131, about its investigative report that concluded that ICOs of the kind The DAO had issued were securities and as such subject to regulations and supervision. 31.

In the wake of a frenzy in the offerings of tokens or coins in digital ventures to the public, also dubbed “initial coin offerings,” or ICOs after the legacy practice of “initial public offerings” of shares or bonds, the US Securities and Exchange Commission (SEC) intervened. It affirmed that ICOs qualify as “securities” that are subject to standard registration requirements, a decision that reached The DAO only posthumously.30 The DAO was a venture capital fund that was built on the Ethereum blockchain. The DAO was designed to operate without a board of directors or any human officers. Instead, the firms’ investors received voting rights that allowed them to participate directly in developing investment strategies by proposing new investment opportunities to the firm. If agreed by the majority of investors, they would be implemented by the code, an open-source software that was available for everyone to see, but not for everyone to change.

v=jw28y81s7Wo This is going to be a bit more of a philosophical talk about the future of cryptocurrencies and what I’ve learned here at this event. This event is called the Bitcoin Expo 2014. It might have been called the Bitcoin and Ethereum Expo 2014. I don’t know if you noticed, but Ethereum had a pretty big presence here. An interesting question comes up, actually quite a few people have asked me: "Does Ethereum threaten the future of bitcoin? Does it steal some of its thunder?" Those are questions I’ve heard several times, and I’ve heard people refer to that issue in trying to understand altcoins - wondering whether altcoins essentially threaten the dominance of bitcoin, if they make bitcoin weaker, if they distribute the value of the network too broadly. 7.1.

"Currency as a means of expression, currency as a tool of language, is no longer up to the issuer. It is up to us as individuals making a choice to use that currency, and we give it value through our use." We’re going to have currencies for different uses. Already, you have bitcoin that provides a very specific monetary policy. You have Ethereum that can provide a contract platform. There’s Namecoin for distributed naming conventions. There are many others, and there will be many others that will solve other problems: protein folding, the search for extraterrestrial life. Maybe we’ll have currencies that are better for microtransactions and micropayments with very fast resolution.

We’re going to start treating currency as an application, and in order to do that we’re going to need interfaces that allow us a unified currency experience, that allow us to have a single wallet with perhaps 150 different currencies in it. Because of inventions like sidechains, decentralized exchanges, fluid liquid systems and the complete absence of monopoly, of lock-in, of hostage situations around the currency, we will be able to instantaneously and at very low cost convert from bitcoin to Namecoin to Dogecoin to Ethereum. If we can do that, then it doesn’t matter because we won’t do that; our unified wallet interface will do that, by trying to see what we’re trying to achieve with our currency. If I’m buying a house, it might express my transactional will in the modality of bitcoin because that is the most suitable currency.

An App functions in very simple way: it is a piece of code that reacts to a certain input to provide the user with a certain output. Press this button on the screen and you are taken to a website or you can call an Uber to come pick you up where you stand. Apps use the information that is being exchanged on the protocol on which they run to perform these activities and deliver these outputs. A smart contract , according to Ethereum’s founder, Vitalik Buterin, “is a computer program that directly controls some digital asset.” Smart Contracts are essentially the same as Apps, except they perform a different kind of automation. While the traditional Apps available on a Google Play Store or Apple App Store are useful for certain operations, Smart Contracts function as Apps that perform value exchange operations when they receive a certain input.

Bitcoin creates an immutable, unchangeable public copy of every transaction ever made by its users, which is hosted and verified by every computer that downloads the software. This public copy is called the ‘blockchain’. Pretty soon, enthusiasts figured out that the blockchain system could be used for anything. Armed with 30,000 Bitcoins (around $12 million) of crowdfunded support, the Ethereum project is dedicated to creating a new, blockchain-operated internet. Ethereum’s developers hope the system will herald a revolution in the way we use the net – allowing us to do everything online directly with each other, not through the big companies that currently mediate our online interaction and whom we have little choice but to trust with our data.

It is likely that architecting it “optimally” is impossible, based on a set of results from a branch of economics called mechanism design. 16.

Once the level of adoption in any neighborhood is sufficiently high, the ridesharing portion of the app gets activated. You can then use your accumulated zooz to buy rides, much like you’d use currency to buy an Uber or Lyft ride. As Vitalik Buterin, an influential writer about decentralized peer-to-peer systems and the founder of Ethereum, a decentralized platform that runs smart contracts, noted in a blog post, “the idea of releasing a new currency as a mechanism for funding protocol development is perhaps one of the most interesting economic innovations to come out of the cryptocurrency space.”14 But a critical determinant of success is architecting this distribution of value right.15 It also seems important for the manifestation of this value, the “coin,” to be of continuing value as the platform grows and matures.

Otherwise, what begins as a decentralized system may simply evolve into a traditional third-party platform that merely uses a glorified blockchain database. Perhaps some of the greatest opportunity from decentralized peer-to-peer systems will come from the emerging decentralized autonomous organizations (DAOs) and decentralized collaborative organizations (DCOs) such as those that are being architected by Buterik’s Ethereum and by Field and DeFillipi’s Backfeed. Such organizations posit a holistic model for organizing economic activity in a decentralized manner. Perhaps these will allow the kind of decentralized, distributed ownership and control of the “platform cooperatives” that I discuss in chapter 8. One might wonder what realistic possibilities exist for organizations that seemingly exist embedded only in computer code.

With Twister, that will not be possible. Then there is Namecoin, which aims to issue internet names in a decentralised, peer-to-peer fashion; Storj, which plans to allow cloud storage of files hidden inside blockchains; and Ethereum, which is a decentralised peer-to-peer network ‘designed to replace absolutely anything that can be described in code’, as Matthew Sparkes puts it. The digital expert Primavera De Filippi sees Ethereum and its ilk coming up with smart contracts, allowing ‘distributed autonomous organisations’ that, once they have been deployed on the blockchain, ‘no longer need (nor heed) their creators’. In other words, not just driverless cars, but ownerless firms.

Bitcoin was designed to maintain its value without any precious-metal backing, without any centralised issuer, and without any intrinsic value. Satoshi invited users to ‘escape the arbitrary inflation risk of centrally managed currencies!’ It is hard to get your head around how bitcoin works. One of the pithiest explanations I have come across is in a recent launch by Ethereum, a business built to follow up on bitcoin: ‘The innovation provided by Satoshi is the idea of combining a very simple decentralised consensus protocol, based on nodes combining transactions into a “block” every ten minutes, creating an ever-growing blockchain, with proof of work as a mechanism through which nodes gain the right to participate in the system.’

Since you can’t go back and edit a blockchain (which is sort of the point of it), this is achieved by ‘forking’ to create a new blockchain. This was done but a significant minority of miners felt that this was the wrong decision so they continued with the original blockchain as Ethereum Classic. At the time of writing, the ‘market cap’ of Ethereum is significantly higher than that of Ethereum Classic. Ripple After Bitcoin and Ethereum, the third biggest cryptocurrency is Ripple, which unlike those first two has its roots in local exchange trading systems (Peck 2013). It is a protocol for value exchange that uses a shared ledger but it does not use a Bitcoin-like blockchain, preferring another kind of what is known as a ‘Byzantine fault-tolerant consensus-forming process’.

Crypto-alternatives Not only will there be cryptocurrencies beyond Bitcoin and not only will they be better – more powerful and more efficient – there will also be a great many of them as the cost of launching a digital currency falls. Without launching into a treatise on cryptocurrencies, I think it would be useful to take a quick look at a couple of the newer cryptocurrencies on the block (pun intended) to give a sense of the spectrum of possibilities. Ethereum Ethereum is comparable to Bitcoin, in that it uses a blockchain, but it was designed to provide a better platform for shared ledger applications. One of the most interesting users of such applications was the Distributed Autonomous Organization (DAO). The general concept of a distributed autonomous organization goes back a few years, having roots in organizational decentralization theories that have been turbocharged (as William Mougayar puts it) by cryptocurrency technologies and trust-based automation (Mougayar 2016), but the DAO in question was created as a new kind of business: an investor-directed investment fund.

There is no abbot of bitcoin who, like the abbot of St Albans, monopolizes bitcoin ASICs—although there is one dominant designer of them, the Chinese company Bitmain, which has some 90 percent of the market (Liu and McMorrow 2019), and the miners who use Bitmain’s ASICs do tend to be organized in very large pools—but there has been deep unhappiness in the world of cryptocurrencies about the shift to ASICs. Indeed, bitcoin’s main rival, ethereum, was designed to be, in the terminology of the field, ASIC resistant. The hashing algorithm for ethereum was designed to make it hard to develop ASICs that are much more efficient than ordinary computers in ethereum’s equivalent of bitcoin mining. Trying to make a cryptocurrency ASIC resistant is quintessential material political economy, reminiscent (as I’ve said) of the defense of hand-milling, even if in the case of ethereum the effort was less than fully successful. Efficient ethereum ASICs have been developed, although they haven’t yet swept the board as fully as their bitcoin equivalents have.

I think it is more generally applicable, and want to end this book by briefly discussing one sphere in which that is most definitely the case, and another in which I think the approach may be applicable (but in which further research is needed to know exactly how). The sphere to which material political economy unequivocally applies is decentralized cryptocurrencies such as bitcoin and ethereum. (The issues are different for cryptocurrencies such as Facebook’s proposed Libra, which, if it is launched, will be run, at least initially, in a centralized fashion; I don’t propose to discuss those currencies here.) The issue that most clearly makes material political economy applicable is how to motivate at least a subset of the users of a cryptocurrency to check the validity of each transaction (including checking the validity of each other’s checking) and take part in adding it irreversibly to the blockchain, the record of every transaction that has taken place.

About the Technical Reviewer Laurence Kirk who after a successful career writing low latency financial applications for the City of London, was captivated by the potential of distributed ledger technology. He moved to Oxford to study for his master’s degree and set up Extropy.io, a consultancy working with start- ups to develop applications on the Ethereum platform. Passionate about distributed technol- ogy, he now works as a developer, evangelist, and educator about Ethereum. Introduction This introduction answers the most important question that every author has to answer: Why should anyone read this book? Or more specifically: Why should anyone read another book about the blockchain?

Instead they typically utilize a dynamic difficulty level based on the speed at which new blocks are added. 3 This ensures that the time needed to solve the hash puzzle stays at a level that prevents nodes from manipulating the history of transaction data while the actual computational effort may increase. 3Okupski, Krzysztof.

Blockchain Basics 143 Outlook This step explained that the blockchain prevents the history of transaction data from being manipulated or forged by turning the blockchain-data-structure into an immutable append-only data store.

How It Works The idea of selecting a transaction history based on the computational effort that was spent for creating it has led to the following two criteria: • The longest-chain-criterion2 • The heaviest-chain-criterion3 The Longest-Chain-Criterion The longest-chain-criterion is based on the idea that the blockchain-data- structure that comprises the most blocks represents the most aggregated computational effort. In order to study this criterion, let’s consider an initial situation were all the nodes of a distributed system maintain and agree on 2Nakamoto, Satoshi.

Such decentralised networks – ranging from a neighbourhood block to a whole city – build community resilience against blackouts and cut long-distance energy transmission losses at the same time. What’s more, the information embedded in every Ethereum transaction allows network members to put their values into action in the microgrid market, for example by opting to buy electricity from the nearest or greenest suppliers, or only from those that are community-owned or not-for-profit.59 And this is just one example of its potential. ‘Ethereum is a currency for the modern age,’ says the cryptocurrency expert David Seaman. ‘It’s a platform that could be really important to society down the road in ways that we can’t even predict yet.’60 These very different examples illustrate a few of the myriad possibilities of monetary redesign, involving the market, the state and the commons.

And since that record is stored on every computer in the network, it acts as a public ledger that cannot be altered, corrupted or deleted, making it a highly secure digital backbone for the future of e-commerce and transparent governance. One fast-rising digital currency that uses blockchain technology is Ethereum, which, among its many possible applications, is enabling electricity microgrids to set up peer-to-peer trading in renewable energy. These microgrids allow every nearby home, office or institution with a smart meter, Internet connection, and solar panel on its roof to hook in and sell or buy surplus electrons as they are generated, all automatically recorded in units of the digital currency.

Saifedean Ammous, The Bitcoin Standard If blockchain is best understood as a tool for public collaboration, and if block rewards are the method by which participants are enticed to discover, expand, and utilize the network’s value, and if that value can be freely transferred, secured, and accounted for in a trust-minimized environment, then a well-designed blockchain invariably exhibits the attributes and functions of money. Since there is no other embodiment of value that can be both fully functional and fully verifiable as a purely digital entity, money necessarily rises to the fore as blockchain’s most compelling use. Many public blockchains such as Litecoin, Zcash, and Ethereum (more to come on these in Chapter 8) are attempting to funnel trust and value into their networks through the creative adaptation of blockchain principles, effectively testing the limits of its functionality, but none are more proficient than Bitcoin. Its value has grown faster than any other asset since its inception,10 and it is the most liquid of all blockchains.

Some of the more well-known examples include Litecoin,15 which aspired to be the silver to Bitcoin’s digital gold, and sometimes moonlights as a testnet for Bitcoin. There is Zcash,16 an enigmatic, privacy-focused currency that broadcasted its launch ceremony live on the Internet, and allots 20% of coin issuance to its founders. There is also Ethereum,17 which initially offered its coins as digital gas for fueling a world computer, and presently fuels a complex economy of digital tokens. Within the broader crypto landscape, some projects are clever and well intentioned, some are outright scams, and some are just electronic Rube Goldberg machines18 – overly touted and complicated systems that provide little real value.

The Litecoin network went live on October 13, 2011. 16Zcash (ZEC) was developed by Electric Coin Company (zcashd) and Zcash Foundation (zebra) on open source. It was initially released on October 28, 2016. 17Ethereum (ETH, also known as Ether) was proposed in late 2013 by Vitalik Buterin, a cryptocurrency researcher and programmer. With its original release on July 30, 2015, Ethereum has an unusually long list of founders. 18Named after American cartoonist Rube Goldberg, this is a machine intentionally designed to perform a simple task in an indirect and overly complicated way. 19Amanda Russo, “Central Banks ‘Waking Up’ to Digital Currency, Create New Framework for CBDC Deployment with World Economic Forum” World Economic Forum (January 22, 2020). 20Nathaniel Popper and Mike Isaac, “Facebook and Telegram Are Hoping to Succeed Where Bitcoin Failed” The New York Times (February 28, 2019). 21Alun John, “China’s digital currency will kick off ‘horse race’: central bank official” Reuters (November 6, 2019).

Platforms to support this kind of decentralized collaborative activity are just coming into being with futuristic names like Ethereum, Sensorica, and Colony. Ethereum is inspired by the success of Bitcoin, an Internet currency that is decentralized, not administered by any single entity. The information about who owns how much Bitcoin is stored in a public ledger of transactions called a block chain. A block chain is a sophisticated technology for maintaining a record of all transactions that is updated and stored across the network of Bitcoin users. Distributing the ledger of transactions across the network is a good way to prevent mistakes and cheating. Ethereum uses a block chain method to allow collaboration via decentralized agreement of everyone involved in a project.

However, to deliver the AI-powered features that near-future users will demand, applications will need to draw upon sophisticated industrial-strength AI software services and harness powerful clusters of data-mining server farms. This stuff doesn’t come cheap. Free, open, and radically decentralized AI isn’t a thing yet, but blockchain-based platforms like Ethereum and Backfeed could offer decentralized alternatives to the corporate cloud. More libre but not gratis, as you’ll pay for decentralization with cryptocurrency. In its infancy, Ethereum is far more expensive than the Amazon cloud but with laughable performance and capability by comparison. Can you afford to wait for the decentralized solution or do you accept that a corporate cloud is presently your only viable high-performance and affordable option?

Put differently, cooperatives tended to focus too much on how the value would be shared rather than on a compelling offer to create the value in the first place. Perhaps part of the solution will come from the possibility, created by blockchain technologies, of “distributed collaborative organizations,” or DCOs—new decentralized collectives that, in the eyes of pioneers like Matan Field of Backfeed and Vitalik Buterin of Ethereum, can use rules embedded in computer code to align the incentives of different contributors, of financial capital, of expertise, of labor, and of participation. These DCOs are connected intellectually to a variety of related decentralized ownership models. They range from the FairShare Model of Karl Sjogren, which proposes a structure of different classes of ownership shares for different contributors—for founders, people with a continuous working role, for users, and for investors—to the Swarm approach to “crypto-equity” crowdfunding developed by Joel Dietz.

We started with an approximately $1 million crowdfunding campaign around our own blockchain-issued asset, the Swarm coin. After much of the funds were exhausted in the process of our own legal research and the coin’s price fluctuations, we financed development through corporate partnerships. At this point we are re-engineering our initial proof of concepts (developed on Bitcoin) to release ready concepts on Ethereum. We are currently building a global ambassador network through training events in various cities across the globe. We are also currently exploring other projects that might bridge to a mainstream audience and serve as a proof of concepts for both the future of governance and community abundance.

—Chief Keef A couple of weeks ago my grandma asked me if she should put some money into Bitcoin. I didn’t know what to tell her. But I knew that in a book about finance I would have to at least give Bitcoin and cryptocurrencies at least a little bit of lip service. For the uninitiated, cryptocurrencies like Bitcoin (and Ethereum, Dogecoin, and Zcash) are digital assets that are designed to function as a medium of exchange and that use cryptography to secure transactions, to control the creation of new money, and to verify asset transfer. Because I think it’s hilarious, I’m going to use Dogecoin1 as the glue for the rest of this chapter.

He first discovered blockchain and cryptocurrency technologies through Bitcoin in 2011, and was immediately excited by the technology and its potential. He co-founded Bitcoin magazine in September 2011, and after two and a half years looking at what the existing blockchain technology and applications had to offer, wrote the Ethereum white paper in November 2013. He now leads Ethereum’s research team, working on future versions of the Ethereum protocol. In 2014, Vitalik was a recipient of the two-year Thiel Fellowship, tech billionaire Peter Thiel’s project that awards $100,000 to 20 promising innovators under 20 so they can pursue their inventions in lieu of a post-secondary institution

Because the technology is evolving so rapidly, I am hesitant to go into much more detail, beyond saying that phasing out paper currency does not really move the needle much on society’s vulnerability to cybercrime. Some of the present-day obstacles to improving security are really more political than economic. Some innovations in security, such as the potentially disruptive distributed-ledger technology embodied in cryptocurrencies like Bitcoin or Ethereum, may eventually lead to major improvements in financial security, at least at the core of the payment system, as discussed further in chapter 14. It is particularly hard to see in any of these arguments why large-denomination notes are important. Probably they would be looked on askance after a power outage, earthquake, or other kind of catastrophe.

And some applications of distributed-ledger technology offer the promise of cutting out intermediaries in transactions between, say, two banks. This would substantially reduce costs, particularly in international transactions. The approach can also be used to save on legal contracting costs. Some of Bitcoin’s competitors, notably the newer Ethereum platform, aim to offer the possibility of creating secure exchanges for transactions of almost any type. People sometimes ask whether the cryptocurrency Bitcoin could be a currency (supposing that the government does not interfere). The answer is certainly yes, Bitcoin (or perhaps one of its present or future competitors) can fulfill many of the basic functions of currency, including unit of account and medium of exchange, with or without government adherence.3 In fact, digital currencies in some ways offer the capacity for much more complex kinds of transactions and contracts than traditional paper currency offers, precisely because the former embed so much information, including the history of transactions.

The answer is certainly yes, Bitcoin (or perhaps one of its present or future competitors) can fulfill many of the basic functions of currency, including unit of account and medium of exchange, with or without government adherence.3 In fact, digital currencies in some ways offer the capacity for much more complex kinds of transactions and contracts than traditional paper currency offers, precisely because the former embed so much information, including the history of transactions. Already, markets are forming to exploit this capacity, for example, in applications surrounding Ethereum.4 That distributed-ledger technology could in theory someday produce a superior currency, however, hardly means that the world is already there in practice. One problem is that the value of Bitcoin 1.0 fluctuates wildly (figure 14.1), so it hardly fulfills the function of a stable store of value.

Such a system combines the best of both tipping and rating, creating a real cost to expressing enthusiasm, but also discouraging free-riding and allowing other participants to benefit from the feedback. A version of this system is being implemented by a social network called Akasha, based on the increasingly prominent Ethereum cryptocurrency.48 QV fits with the framework of cryptocurrencies, which require formal governance rules to allow for the decentralized management they rely on, so using it also for social aggregation in such a context is natural. However, the exact implementation is unclear at the time of this writing, and not available to the public; much in the world of cryptocurrencies is secretive.

He had been on 4chan, the dark web, looking for vintage porn to buy and sell for profit. He went on Silk Road and saw people using Bitcoin, and he thought it was more of a PayPal-type thing. But as he learned more, he started buying it, a little every month. One night, here at IndieBio, Tall Joe hosted the first-ever Ethereum Meetup Group for San Francisco. Thirteen people showed up, but one of them was the CTO for the Ethereum Foundation. Ethereum was almost out of money, and at the time nobody knew if Ether would survive. But Joe bought a bunch because he thought smart contracts made sense. Joe took a coding class in San Jose and started buying into ICOs he thought would have a real market.

Let me revise that; they’re not agreeing to pay your debt long-term, it’s more like your parents would be your escrow company, putting up their own money only for the length of time it takes for the transaction to go through. This method would end the arms race, but making this paradigm shift would be too radical for Bitcoin to go first. So other crypto assets, like Ethereum, will do it first. The Bitcoin community is pretty convinced they need to find a new solution. But the community is very divided over what the new solution should be. So let’s summarize a little bit. 1. Bitcoin has no intrinsic value. 2. But big money needed an alternative to the dollar. 3.

In effect, people found that they could create their own currencies using Bitcoin as a model. These would be known as decentralized autonomous organizations (DAOs). The first of these, DAO Maker, had an inauspicious beginning. The company used Ethereum (a decentralized currency built using a protocol similar to the Bitcoin blockchain) as its platform. A hacker figured out that when money was moving from one entity to another, they could siphon off the Ethereum currency, called Ether, collected from the sale of the tokens. The hacker managed to steal 3.6 million Ether (at the time valued around $72 million) and the price of Ether dropped from $20 to about $13.

The doctor who ran this clinic, Eric Scott Sills, was later arrested and charged with murdering his wife and business partner.4 * * * When Ascendance Biomedical launched their new website, http://ascendance.io, in December 2017, they invited the public to “Help Us Choose Our Next Experiments.” Tristan Roberts designed the front end of the website, plus a back-end cryptocurrency infrastructure that would enable anyone to invest in the project, undetected by the government. Rather than Bitcoin, the best-known cryptocurrency, the group was banking on Ethereum, a newer currency that was growing exponentially in value. One coin (known as an “ether”) was valued at $299 in early November 2017, and the price skyrocketed to $821 just before Christmas. Ascendance offered a diverse menu of options on their website. An estrogen/testosterone experiment topped the list of possible treatments.

Cryptocurrencies make it easier to transfer funds between two parties in a transaction, and with minimal processing fees compared to the steep fees charged by most financial institutions. The adoption rate of cryptocurrencies is increasing daily with banks, corporations, and governments recognizing its mainstream popularity. The current leading cryptocurrencies are Bitcoin, Ethereum, Litecoin, Monero, Dash, and Ripple. A popular way to buy and sell cryptocurrencies and create your own digital currency “wallet” is to use a platform like Coinbase.com or Bittrex.com. Speculative investors should be aware there are risks involved in the investment and use of cryptocurrencies, such as fraud and security of the platforms.

But JavaScript, including Node.js, is designed to be modular, where each maintainer has a limited ability to affect other components of the ecosystem, so JavaScript developers are more likely to prioritize moving fast and accepting contributions. In cryptocurrency, these philosophies play out as visible differences in how the Bitcoin and Ethereum projects are managed. Bitcoin’s community, like Clojure’s, prioritizes stability and security, preferring to move slowly and with care, even if it means including fewer features and contributors. Ethereum is more like Node.js: it’s a platform for others to develop on, flinging itself far and wide. It resembles a sprawling city like Los Angeles, comprised of many neighborhoods and subcultures. Despite impassioned rants to the contrary (if there’s one thing I’ve learned, it’s that developers have opinions), there’s no one right way of doing things, just different communities that each have their own cultural norms.

Moreover, as you put money into that machine, you and its other users have a say in what snacks it will order and how often it should be cleaned. It has no managers, all of those processes were pre-written into code.” Developers, leveraging what they have learned in creating cryptocurrencies such as Bitcoin and Ethereum, are pioneering a new generation of decentralized applications that allow organizations to operate like that magical vending machine. Through a series of rules called smart contracts, founders can create, fund, and operate an entire organization independent of hierarchical management. Everything, from paying contributors for their work to making decisions about investment, is managed in a distributed way.

Using BaconCoin, LoanSnap aims to revolutionize home buying by sharing mortgages via the blockchain that can etch every transaction from day one.20 The first such mortgages changed hands in late 2021. Once inscribed on a blockchain visible to every user, new transactions update the status quo but, in principle, no one can alter or hack what occurred in the past. The rush to DeFi is premature and ultimately misguided. The rapid rise of Bitcoin, Ethereum, Dogecoin, and thousands of fledgling cryptocurrencies since 2010 exposes our collective wilting faith in the ability of governments to back the money they issue. But elevating crypto to the status of legitimate currencies endorses a dangerous precedent that is most likely to fail miserably. Fabio Panetta, member of the European Central Bank executive board, gave a sober update in December 2021.

Were someone to write a mortgage with principal and interest in bitcoin, a spike in the value of bitcoin would cause the real value of the mortgage to skyrocket. If default then likely occurs, the lender loses money, and the borrower loses her house. A true currency should also be a scalable and widely used means of payment. Bitcoin and Ethereum can handle fewer than a dozen transactions per second, due to the enormous computing resources involved. The Visa network, by contrast, handles fifty thousand transactions per second. The proof-of-work etched into every blockchain transaction may improve its reliability, but it does so at a snail’s pace.

* Bitcoins can be divided into eight decimal places. The smallest non-divisible unit is known as a ‘Satoshi’. * In 2015 a company called the DAO (decentralised autonomous organisation) was founded as an investor-directed capital fund, which exists only virtually, as a series of public smart contracts. Investors can buy shares in the DAO using Ethereum’s (another blockchain) currency, which gives votes on investments. Anyone anywhere in the world can invest, it’s all transparent, there is no board or employees at all, and shareholders receive any profits directly. One month after it was launched to great fanfare, hackers and/or investors managed to exploit a vulnerability by inserting some code that redirected shares into their personal wallets, allowing them to walk off with millions of dollars of investors’ money.

Artificial intelligence does the rest. The entire experience is mobile, simple, and fast. Ninety seconds to get insured, three minutes to get a claim paid, and zero paperwork. Adding more technology to this arrangement, companies like the Swiss firm Etherisc sell “bespoke insurance products” on the Ethereum blockchain. Because smart contracts remove the need for employees, paperwork, and all the rest, all sorts of new insurance products are being created. Etherisc’s first offering is something not covered by traditional insurers: flight delays and cancellations. Individuals sign up via credit card, and if their plane is more than forty-five minutes late, they’re paid instantly, automatically, and without the need for any paperwork.

But instead of being wired with a microphone or taken to a stage, I just sat there at a plain round table as my audience was brought to me: five super-wealthy guys – yes, all men – from the upper echelon of the hedge-fund world. After a bit of small talk, I realized they had no interest in the information I had prepared about the future of technology. They had come with questions of their own. They started out innocuously enough. Ethereum or bitcoin? Is quantum computing a real thing? Slowly but surely, however, they edged into their real topics of concern. Which region will be less impacted by the coming climate crisis: New Zealand or Alaska? Is Google really building Ray Kurzweil a home for his brain, and will his consciousness live through the transition, or will it die and be reborn as a whole new one?

Aside from the money that had paid for it, the machine seemed to have nothing to do with AlphaBay. The laptop, on the other hand, was a gold mine of evidence—quite literally. Aside from being logged in to AlphaBay and containing that incriminating net worth file, the computer had keys for all of Cazes’s various wallets, containing not only Bitcoin but also other, newer cryptocurrencies: Ethereum, Monero, Zcash. Rabenn remembers watching the two FBI analysts, Ali and Erin, in the war room as they siphoned that money into wallets under FBI control, announcing every time they had transferred another multimillion-dollar stash. “It was the coolest thing I have ever seen,” Rabenn says. On the evening after the arrest, Rabenn and Hemesath met with Cazes for the first time.

Nonetheless, the libertarian protestations of a certain set of coders continues apace. In recent years, blockchain technology has been the latest site of tech’s anti-government fervor. That ranges from Bitcoin—a currency specifically designed to create money that couldn’t be controlled by dough-printing central banks—to Ethereum, a way of creating “smart contracts” that, its adherents hope, would allow commerce so frictionless and decentralized that even lawyers wouldn’t be necessary: The instant someone performed the service you’d contracted them to do for you, the digital cash would arrive in their digital wallet. One survey of people in the cryptocurrency community found that fully 27 percent called themselves libertarian, more than double the rate Pew Research Center found in the general population.

And what is meant by ‘money’ is temporally and geographically specific. Money is dollars in the US, and euros in Europe. Not so long ago, money was gold and silver. For the inhabitants of Yap in the Caroline Islands, money was Rai, heavy circles of limestone with a hole in the middle. Some people think that crypto-currencies such as Bitcoin and Ethereum are ‘money’. Numbers are essential to economic analysis. But economic data and economic models are never descriptive of ‘the world as it really is’. Economic interpretation is always the product of a social context or theory. Expressing uncertainty When we are wondering whether the man in the compound is bin Laden or what happened to the Mary Celeste , whether the second Smith child is a girl or whether Joyce met Lenin, probabilities are unhelpful.

The first block on the Bitcoin blockchain was created along with the text “THE TIMES 03/JAN/2009 Chancellor on brink of second bailout for banks”—the anti-centralization message of Bitcoin coming through loud and clear. And since 2008, the cryptocurrency and blockchain space has blossomed beyond Bitcoin into other currencies and other blockchains, currencies like Ethereum and EOS, all with slightly different consensus algorithms—ways of ensuring that individual computers, or nodes, have records that agree with each other. Hardin’s original essay in 1968 used the example of the medieval commons, a place where peasants grazed their cows. According to Hardin, the ungoverned nature of the commons led to overgrazing, which is why the commons had to eventually be enclosed and privatized.

They sat around the table and introduced themselves: five super-wealthy guys—yes, all men—from the upper echelon of the tech investing and hedge fund world. At least two of them were billionaires. After a bit of small talk, I realized they had no interest in the talk I had prepared about the future of technology. They had come to ask questions. They started out innocuously and predictably enough. Bitcoin or Ethereum? Virtual reality or augmented reality? Who will get quantum computing first, China or Google? But they didn’t seem to be taking it in. No sooner would I begin to explain the merits of proof-of-stake versus proof-of-work blockchains than they would move to the next question. I started to feel like they were testing me—not my knowledge so much as my scruples.

A ‘smart contract’, for instance, is a piece of blockchain software that executes itself automatically under pre-agreed circumstances— like a purchase agreement which automatically transfers the ownership title of a car to a customer once all loan payments have been made.27 There are early ‘Decentralised Autonomous Organisations’ (DAOs) that seek to solve problems of collective action without a centralized power structure.28 Imagine services like Uber or Airbnb, but without any formal organization at the centre pulling the strings.29 The developers of the Ethereum blockchain, among ­others, have said they want to use DAOs to replace the state altogether. Blockchain still presents serious challenges of scale, governance, and even security, which are yet to be overcome.30 Yet for a youthful technology it is already delivering some interesting results. The governments of Honduras, Georgia, and Sweden are trialling the use of blockchain to handle land titles,31 and the government of Estonia is using it to record more than 1 million patient health records.32 In the UK, the Department for Work and Pensions is piloting a blockchain solution for the payment of welfare benefits.33 In the US, the Defense Advanced Research Projects Agency (DARPA) is looking into using blockchain technology to protect its military networks and communications.34 Increasingly connective technology is not just about people connecting with other people.

Paris Hilton tweeted support for Lydian Coin and Floyd ‘Crypto’ Mayweather, as the retired boxer now styled himself, endorsed several issues over social networks (for which he was later fined by the Securities and Exchange Commission). Like the ‘bubble companies’ of 1720 that promised to extract silver from lead or to build an air pump for the brain, several of the new cryptos were spoofs. But that didn’t stop the Useless Ethereum Token, whose logo showed the middle finger and whose website advised ‘don’t buy these tokens’, rising five times faster than Bitcoin in the giddy last months of 2017.25 Just as internet companies were spun off from their parents during the Dotcom bubble, so ‘forks’ in the blockchain created yet more coins.

Named after John Maynard Keynes, the economist who is most strongly identified with this particular approach to monetary policy 14. One well-articulated version of this argument is given by Paul Krugman in the article “Bitcoin Is Evil,” New York Times, December 28, 2013, http://krugman.blogs.nytimes.com/2013/12/28/bitcoin-is-evil/. 15. http://ethereum.org/ 16. http://bitmessage.org/ Chapter 7: The Cryptography Behind Bitcoin 1. This term is used in addition to the many others for Bitcoin, such as digital currency, math-based currency, and among those who don’t think bitcoins are real money, virtual currency. 2. An integer is a number that can be written without a fractional or decimal component (e.g., −4, 2, or 17 but not 4.23 or 1.5). 3.

* The rapid development of new technologies is also a significant difficulty to address, in terms of trying to predict the impact these will have in the coming years – and working out how to prepare accordingly for a world where artificial intelligence (AI), robotics, machine learning, Blockchain, Ethereum and more will change the way we live, love, work and communicate. Then there are cryptocurrencies like Bitcoin, which, while exciting for digital pioneers, seem most obviously of interest to those who seek to keep their transactions secure and away from prying eyes – including those who deal in illicit substances or goods, or who prefer to keep potentially taxable revenue away from the authorities.

They’ve seen other big old companies get killed off by Silicon Valley, and they would rather not have this happen to them. They seem to believe that some magic elixir exists here, some recipe for innovation that floats in the air and can be absorbed if you drive around with your windows open, smelling the eucalyptus trees. They see people getting rich on things they don’t even understand. Blockchain? Ethereum? Initial coin offerings? So they fly out and have drinks at the Rosewood Hotel on Sand Hill Road in Menlo Park, where venture capitalists hang around, as do expensive “companions,” many with Eastern European accents. They eat lunch at the Battery, a members-only private club for social-climbing parvenus in San Francisco.

In the same way that Internet communications have seen costs drop to near zero, we expect to see internal organizational and transactions costs also fall to near zero as we increasingly information-enable and distribute our organizational structures. Ultimately, in the face of such low transaction costs, we anticipate what we’re calling a Cambrian Explosion in organizational design—everything from community-based structures to virtual organizations (see Ethereum) that will be small, nimble and extensible. It is also becoming increasingly clear that, like the Internet, the ExO paradigm is not just for business. It can just as easily be applied to all sorts of enterprises and organizations, from academia to non-profits to government. In short, it is not just a system of commerce, but also a philosophy of action.

Much more content can be embedded in the transaction “Payer X wants to send Y Bitcoins to payee Z.” See the Bitcoin transaction as a subject-verb-object command. All kinds of important data relating to the subject and object (name, address, ratings, contingencies), and all types of actions (rent, buy, barter, rideshare, publish) could be substituted in. Budding companies—LaZooz, Swarm, and Ethereum, to name three—are fleshing out this idea. Any kind of business or personal transaction needing standard contracts, for standard actions, with standard rules could all be sent, appended, and amended using the block chain. Every transaction can have its own special combination built using standard building blocks.

A transaction log can be made tamper-proof by periodically signing it with a hardware security module, but that does not guarantee that the right transactions went into the log in the first place. It would be interesting to use cryptographic tools to prove the integrity of a system in a way that is robust to a wide range of hardware and software issues, and even poten‐ tially malicious actions. Cryptocurrencies, blockchains, and distributed ledger tech‐ nologies such as Bitcoin, Ethereum, Ripple, Stellar, and various others [71, 72, 73] have sprung up to explore this area. I am not qualified to comment on the merits of these technologies as currencies or mechanisms for agreeing contracts. However, from a data systems point of view they contain some interesting ideas. Essentially, they are distributed databases, with a data model and transaction mechanism, in which different replicas can be hosted by mutually untrusting organizations.

A transaction log can be made tamper-proof by periodically signing it with a hardware security module, but that does not guarantee that the right transactions went into the log in the first place. It would be interesting to use cryptographic tools to prove the integrity of a system in a way that is robust to a wide range of hardware and software issues, and even potentially malicious actions. Cryptocurrencies, blockchains, and distributed ledger technologies such as Bitcoin, Ethereum, Ripple, Stellar, and various others [71, 72, 73] have sprung up to explore this area. I am not qualified to comment on the merits of these technologies as currencies or mechanisms for agreeing contracts. However, from a data systems point of view they contain some interesting ideas. Essentially, they are distributed databases, with a data model and transaction mechanism, in which different replicas can be hosted by mutually untrusting organizations.

Speaking of reserve currencies, Bitcoin introduces addressable scarcity not in direct relation to the sum of mined minerals or national currencies, but by the mathematics of solving increasingly difficult problems toward an eventual arbitrary limit of 21 million “coins.” There is much to explore with Bitcoin, blockchains and related initiatives, such as Ethereum, but it is also the monetary platform of choice of secessionist projects for which the metaphysical expulsion of externalities is the paramount program, as important if not more than the disintermediation of central banks. The version of Bitcoin that we have (other currencies may fork or follow) is exemplary of the future-archaic quality of many Stack innovations.

Narrative economics, the study of the viral spread of popular narratives that affect economic behavior, can improve our ability to anticipate and prepare for economic events. It can also help us structure economic institutions and policy. To get a feel for where we are going, let’s begin by considering one such popular narrative, recently in full swing. Bitcoin, the first of thousands of privately issued cryptocurrencies—including Litecoin, Ripple, Ethereum, and Libra—has generated enormous levels of talk, enthusiasm, and entrepreneurial activity. These narratives surrounding Bitcoin, the most remarkable cryptocurrency in history as judged by the speculative enthusiasm for it and its market price rather than its actual use in commerce, provide an intuitive basis for discussing the basic epidemiology of narrative economics (which we explore in detail in chapter 3).

At the end of 2019, the organization recruited a new CEO, James O’Neill, a longtime employee at Thiel’s companies (and one of Thiel’s suggestions to run the FDA). At the time of my visit, SENS had been enjoying some modest success, having spun out several research projects into early-stage companies and attracted a number of new donors, including Vitalik Buterin, the creator of the technology behind the Ethereum cryptocurrency and, years earlier, a Thiel Fellow. But Thiel himself had not been among those recent contributors. His last donation to SENS had been in 2016. De Grey also mentioned that, despite talking up SENS’s work often in the press, Thiel had never actually visited the nonprofit’s laboratory, which is located just eight miles from Palantir’s Palo Alto office.

A study undertaken by the World Economic Forum and Bain estimates that further aligning supply chain standards would boost world GDP by an enormous 5 percent, while implementation of all current WTO accords would deliver only 1 percent growth. The Ethereum blockchain platform will allow for standardized and transparent contracts between trading parties beyond any single jurisdiction and, when combined with real-time data sharing on supply chain transactions, can substantially reduce the cost of insuring trade. Open trade and open borders further reorganize the world into functional circuits.
