To gain a .bit site, one must have namecoin to do so, thus the need for the native asset. Litecoin While a handful of altcoins were released through 2011, Litecoin was the first that would retain significant value to this day. The cryptocurrency was developed by Charlie Lee, an MIT graduate who was a software engineer at Google. When Lee learned of Bitcoin he quickly understood its power, leading him to mine bitcoin before trying to create his own variants. After the unsuccessful launch of Fairbrix in September 2011, Lee tried again with Litecoin in October.18 Litecoin aimed to improve upon Bitcoin in two ways. For one, Litecoin’s block times were 2.5 minutes, four times faster than Bitcoin’s, which would be important for merchants needing faster confirmation of consumer’s payments. Second, Litecoin used a different hash function in the proof-of-work process—also known as a block hashing algorithm—which tried to make the mining process more accessible to hobbyists.

Figure 4.3 The comparative supply schedules of Litecoin and Bitcoin It’s important to realize that if bitcoin and litecoin are both being used in similar size markets and therefore have the same size network values, a unit of litecoin will be one-fourth as valuable as a unit of bitcoin because there are four times as many units outstanding. This is an important lesson, because all cryptocurrencies differ in their supply schedules, and thus the direct price of each cryptoasset should not be compared if trying to ascertain the appreciation potential of the asset. Litecoin’s network is often used as a testing ground for Bitcoin software updates, given that Litecoin is nimbler than Bitcoin because it stores a fraction of the monetary value. It has also been used as the basis for other cryptoassets. At the start of 2017, litecoin was the fourth largest cryptoasset in terms of network value.20 Ripple Ripple is a cryptocurrency created in 2004 by Ryan Fugger, a web developer from Vancouver, British Columbia.

Lee wanted a coin that retained its peer-to-peer roots and allowed users to be miners without the need for specialized and expensive mining units. Litecoin accomplished this by using a block hashing algorithm called scrypt, which is memory intensive and harder for specialized chips like ASICs to gain a significant edge upon. Other than these two tweaks, much of Litecoin remained similar to Bitcoin. The innovative investor will have realized, however, that if blocks are issued four times as fast as bitcoin, then the total amount of litecoin released will be four times greater than that of bitcoin. This is exactly the case, as litecoin will converge upon a fixed 84 million units, whereas bitcoin will converge upon a quarter of that, at 21 million units.19 Lee tweaked the halving characteristics, too, so that a halving occurs at 840,000 blocks, as opposed to bitcoin’s 210,000. As Figure 4.3 shows, this puts litecoin on a similar yet larger supply trajectory than bitcoin.

Given the status of Coinbase as a payment processor and a bridge to the fiat world, adoption by Coinbase would be extremely beneficial to Litecoin. Other than the Charlie Lee connection, however, there are currently no indications that Coinbase will ever accept Litecoin. From a technical standpoint, Litecoin is faster than Bitcoin. With the same block size as Bitcoin and a much shorter block time, the network is capable of performing more transactions per second than Bitcoin in its current form. Bitcoin’s block size isn’t set in stone and there is an ongoing debate over changing the size of the blocks, but for now, Litecoin remains faster. Recently, Litecoin started merge mining (i.e., mining two coins with the same algorithm at the same time) with Dogecoin. Both coins use Scrypt, so hashrates can be put toward both coins simultaneously. There was no downside for Litecoin miners and the merge helped secure the Dogecoin network by bringing Litecoin miners onto it.

Dogecoin had gained a large overall market cap and with its hashrate quickly dropping, a 51% attack became a real possibility. The solution came by way of Litecoin. After much discussion in both communities, Litecoin decided to enable merged mining with Dogecoin. Despite the exceedingly small rewards available on the Dogecoin network, Litecoin miners still benefited from this decision. Since they use the same algorithm, both coins can be mined simultaneously without a decrease in mining of either.5 What this did was enable Dogecoin’s network to be secured by Litecoin’s miners, and anyone looking to force a double-spend through a 51% attack would have to match both the Litecoin network’s hashrate and that of Dogecoin. Afterward, merge mining became a popular feature in a lot of smaller cryptocurrencies. Dogecoin isn’t the future of Internet currency, as even its most adamant supporters admit.

The idea was to use a CPU-minded algorithm with the intention of bringing mining back to home computers and away from specifically designed hardware. For a while, it worked. Litecoin was and remains a more viable mining option for those looking to mine at home. It has, however, run into the same problems as Bitcoin, and mining at home is not recommended, though it remains far more feasible than mining Bitcoin. ASICs designed to mine Scrypt were eventually released and as Litecoin became more popular, its difficulty followed a curve similar to that of Bitcoin. Even with its price dropping over the past few years, Litecoin’s difficulty has continued to rise, and mining profitability is razor-thin even with cutting-edge hardware. Mining on a home computer is more likely to damage your hardware than net you any Litecoin. That said, if one has free or extremely cheap electricity, some home mining is possible.

As is the case with bitcoin PoW, in Scrypt also if the output hash is less than the target hash (already passed as input at the start, stored in memory, and checked with every iteration) then the function terminates; otherwise, the nonce is incremented and the process is repeated again until a hash is found that is lower than the difficulty target. Scrypt ASIC design simplified flowchart Trading litecoin: As with other coins, trading litecoin is easily carried out on various online exchanges. The current market cap of litecoin is $10,448,974,615. The current price (as of March, 2018) of litecoin is $188.04/LTC. Mining: Litecoin mining can be carried out solo or in pools. At the moment, ASICs for Scrypt are available that are commonly used to mine Litecoin. Litecoin mining on a CPU is no longer profitable as is the case with many other digital currencies now. There are online cloud mining providers and ASIC miners available that can be used to mine Litecoin. Litecoin mining started from the CPU, progressed through GPU mining rigs, and eventually now has reached a point where specialized ASIC miners, such as ASIC Scrypt Miner Wolf are available from Ehsminer are now required to be used in the hope of being able to make some coins.

Generally, it is true that even with ASICs it is better to mine in pools instead of solo as solo mining is not as profitable as mining in pools due to the proportional rewards scheme used by mining pools. These miners are capable of producing a hashing rate of 2 Gh/s for Scrypt algorithms. Software source code and wallet: The source code for litecoin is available at The Litecoin wallet can be downloaded from and can be used just like the Bitcoin core client software. Primecoin Primecoin is the first digital currency on the market that introduced a useful PoW, as opposed to Bitcoin's SHA256-based PoW. Primecoin uses searching prime numbers as a PoW. Not all types of prime number meet the requirements to be selected as PoW. Three types of prime numbers (known as Cunningham chain of the first kind, Cunningham chain of the second kind, and bi-twin chains) meet the requirements of a PoW algorithm to be used in cryptocurrencies.

It uses Scrypt as PoW, originally introduced in the Tenebrix coin. Litecoin allows for faster transactions as compared to bitcoin due to its faster block generation time of 2.5 minutes. Also, difficulty readjustment is achieved every 3.5 days roughly due to faster block generation time. The total coin supply is 84 million. Scrypt is a sequentially memory hard function that is the first alternative to the SHA-256-based PoW algorithm.

There are hundreds of cryptocurrencies, of which Bitcoin is the first and largest. Others include Litecoin, Dogecoin, Ripple, NXT, and Peercoin; the major alt-currencies can be tracked at Table 1-1. Layers in the technology stack of the Bitcoin blockchain Cryptocurrency: Bitcoin (BTC), Litecoin, Dogecoin Bitcoin protocol and client: Software programs that conduct transactions Bitcoin blockchain: Underlying decentralized ledger The key point is that these three layers are the general structure of any modern cryptocurrency: blockchain, protocol, and currency. Each coin is typically both a currency and a protocol, and it may have its own blockchain or may run on the Bitcoin blockchain. For example, the Litecoin currency runs on the Litecoin protocol, which runs on the Litecoin blockchain. (Litecoin is very slightly adapted from Bitcoin to improve on a few features.)

The concept and operational details are described in a concise and readable white paper, “Bitcoin: A Peer-to-Peer Electronic Cash System.”7 Payments using the decentralized virtual currency are recorded in a public ledger that is stored on many—potentially all—Bitcoin users’ computers, and continuously viewable on the Internet. Bitcoin is the first and largest decentralized cryptocurrency. There are hundreds of other “altcoin” (alternative coin) cryptocurrencies, like Litecoin and Dogecoin, but Bitcoin comprises 90 percent of the market capitalization of all cryptocurrencies and is the de facto standard. Bitcoin is pseudonymous (not anonymous) in the sense that public key addresses (27–32 alphanumeric character strings; similar in function to an email address) are used to send and receive Bitcoins and record transactions, as opposed to personally identifying information.

KeyID, rebranded from Keyhotee, provides an identification and email system on a decentralized blockchain for secure messaging and for secure authentication.81 Freedom of Speech/Anti-Censorship Applications: Alexandria and Ostel Alexandria is one example of a blockchain-based freedom-of-speech-promoting project. It aims to create an unalterable historical record by encoding Twitter feeds to a blockchain. Any tweets mentioning certain prespecified keywords (like Ukraine or ebola) are encoded into the Alexandria blockchain using Florincoin, a cryptocurrency based on Bitcoin and Litecoin with quick transaction processing (40 seconds) and a longer memo annotation field (conceptually: Memocoin). This method captures tweets that might be censored out later by takedown requests.82 Florincoin’s key enabling feature for this is transaction comments, a 528-character field for the recording of both metadata and tweet content.83 The expanded commenting functionality could be used more broadly for many kinds of blockchain applications, such as providing metadata and secure pointers to genomic sequences or X-ray files.

Nevertheless, the best altcoins are bringing an edgy and potentially constructive force of competition to bear in the whole cryptocurrency arena. Of these altcoins, litecoin, invented by Charlie Lee, is to date the most successful. Litecoin’s secret sauce is its use of a different algorithm in the hashing process that miners use to package transactions into the blockchain. Lee’s system still involves a competition among miners, but its hashing algorithm, known as scrypt, makes it easier for a miner to arrive at the sought-after block hash goal than does bitcoin’s SHA-256. Without delving into the complicated details of how it works, scrypt essentially tweaks the targets so that miners don’t simply gain an advantage by constantly building up brute computational power. The result is that mining power remains somewhat more evenly spread and more democratic with litecoin. Miners still have an incentive to chase coin rewards, but the arms race and the electricity usage aren’t as intense.

It also makes for faster turnarounds, with blocks completed within two and a half minutes, rather than bitcoin’s ten minutes, which in turn means the system’s wait for the final confirmation of transactions by customers and merchants isn’t as long. Litecoin’s main weakness is the corollary of its strength: because it’s cheaper to mine litecoins and because scrypt-based rigs can be used to mine other scrypt-based altcoins such as dogecoin, miners are less heavily invested in permanently working its blockchain. In theory, that could raise the risk of a 51 percent attack if enough of them aren’t online at any one time. Some also worry that scrypt-based mining is more insecure, with a less rigorous proof of work, in theory allowing false transactions to get through with incorrect confirmations. Thus far, however, litecoin has avoided major breakdowns. In time it could prove to be a more environmentally friendly, democratic contender to bitcoin.

One solution to electric costs and overheated computers is to mine in cold weather if there is a cheap power source for electricity. A British programmer decided to build his mine in Reykjanesbaer, Iceland, so his computers can run on geothermal and hydroelectric energy while being cooled by the arctic air. Litecoin markets itself as being more abundant and faster to mine than bitcoins. Charlie Lee, a former Google software engineer, designed Litecoin in his spare time and launched it in 2011 to complement Bitcoin. Lee said, “People like choices. You want to diversify your cryptocurrency investments.” He has described Litecoin as “silver to Bitcoin’s gold,” and he designed the Litecoin software to produce 84 million litecoins in comparison to Satoshi Nakamoto’s design for 21 million bitcoins. Lee also decided to use scrypt cryptography to reduce mining rates per unit down to 2.5 minutes in comparison to Bitcoin’s 10 minutes.

THE FUTURE OF CODED TRUST The lines of the debate extend beyond Bitcoin into the larger universe of digital currencies. There are now hundreds of other cryptocurrencies, including those with names as priceless as Darkcoin, CryptoMETH, BattleCoin, and PiggyCoin. Even with all these rivals, Bitcoin’s market capitalization remains well above the competition. In June 2015, it had a total valuation of $3.2 billion. Its two nearest competitors were Ripple (total value $256 million) and Litecoin ($71 million). Many of Bitcoin’s competitors seek to correct perceived shortcomings in Bitcoin itself, including its limited (and thus potentially deflationary) supply; its “irreversibility,” which does not allow for errors to be corrected; and even its negative environmental impact. Mining requires significant computing power, which in turn requires significant energy. Serious bitcoin miners can spend upward of $150,000 a day on electricity nearby.

Trading is so thin in any crypto, even Bitcoin, that you could never realise a fraction of the number. If you want to compare interest and activity in crypto assets, you need to compare trading volumes, if you can find good numbers for those. Litecoin Litecoin is the “me too” coin. It hasn’t many interesting stories, but it was the most prominent altcoin before the first Bitcoin bubble burst; for a few years, sites like the Pirate Bay that accepted Bitcoin donations often also accepted Litecoin donations. It was marketed as “the silver to Bitcoin’s gold.” The main difference from Bitcoin is a different hash designed to be resistant to GPU mining (though ASICs eventually came out) and a shorter block time. Litecoin’s price went up with Bitcoin’s until 2013, the price crashed with Bitcoin’s, and during 2014 it declined from its peak of $42 (spot prices of $68 on some exchanges) to $1.50.

Bobby showed up at the company’s makeshift offices in a converted three-bedroom apartment a day after the company announced the $25 million investment from Andreessen Horowitz. Charlie Lee didn’t need to work another day of his life. Litecoin, his alternative cryptocurrency, which was a slightly faster, lightweight version of Bitcoin, had now become the second-most-popular cryptocurrency in what was becoming an increasingly crowded field of Bitcoin knockoffs. In part because of Charlie’s transparency in launching Litecoin, people trusted it and were betting that it would be, as Charlie had intended, the silver to Bitcoin’s gold. In November the value of all the outstanding Litecoins had briefly surpassed $1 billion. The particular computer chips that were good for mining Litecoins were sold out at nearly every online electronics retailer. Charlie had been mining Litecoins since the beginning, so he owned a sizable number of the coins, along with his significant Bitcoin holdings.

Bobby Lee, who generally wore the same khaki pants and blue dress shirt day in and day out, alternated between flawless English and imperfect Shanghainese as he explained his vision for Bitcoin’s potential in the world’s most populous nation. WHEN BOBBY LEE had first reached out to the founders of BTC China in February 2013, he was much less well known in the Bitcoin world than his younger brother, Charlie Lee, the California-based Google engineer who had been involved in Bitcoin since 2011 and who was perhaps best known as the creator of Litecoin, one of the most successful alternative virtual currencies. It was Charlie who had pushed Bobby, and the rest of his family, to first look at Bitcoin back in 2011. Bobby had a natural interest for the same reasons as his brother. The two men, who grew up sharing a bedroom, had both studied computer science, Charlie at MIT, Bobby at Stanford. Perhaps more important, both grew up in the Ivory Coast as the children of Chinese immigrants who had escaped the communist revolution with only the wealth they had stored in gold.

Krugman focused largely on Bitcoin’s claim to be a currency, given the difficulty it seemed to have fulfilling one of the basic roles of money: serving as a reliable store of value. Why would people store their wealth in Bitcoin if they knew the value was going to fluctuate so violently? Krugman asked. Cowen, meanwhile, argued that Bitcoin was going to have difficulty sustaining its value as new and better-designed cryptocurrencies came along and drew users away from it. Some people were, indeed, already choosing to hold Litecoin, Charlie Lee’s creation, and a hip, younger cryptocurrency, Dogecoin. But a deeper strain lurking beneath these critiques was an awareness that one of the fundamental premises that had driven Bitcoin’s popularity seemed, increasingly, to have been disproved. Many early Bitcoiners, particularly in the libertarian camp, had believed that the Federal Reserve’s efforts to stimulate the economy in the wake of the financial crisis, by pumping lots of new money into banks, would devalue the dollar and lead to high inflation, similar to what had happened in Argentina.

Serious crime, such as child pornography, and drugs and arms trading, are attracted to cryptocurrencies because of its efficiency, secrecy and speed. Petty crime, like selling medicine online or ghost-writing essays for inept students, also uses crypto for secrecy.16 Blockchain-based innovations have become the favourite method of payment in the criminal underworld. An Australian study estimated that about 47 per cent of transactions involving bitcoin are conducted on the darknet. Litecoin, the second-most-popular cryptocurrency preferred by Russians, is now accepted by nearly one-third of all dark-web vendors.17 The industry, of course, rejects any such claims. It gets worse. In a world where anyone can create money, crime groups have an interest in launching their own money transmission services and popularizing them as legitimate ‘fintech’ alternatives. As more and more jobs and services go off the official economic radar into the underground of the ‘gig’ economy, exchanging their skills for money, the more bitcoin and other cryptocurrencies offer a convenient way around the traditional income reporting demanded of employees and independent contractors.18 The authorities have taken steps to try and regulate the crypto world.

Still, Tezos’s contribution to the development of more robust governance systems has been an important one. Every new idea will have shortcomings, yet, if developed by serious engineering teams, each idea can move the ball forward toward decentralization, functional governance, scalability, and privacy. This has been so with altcoins such as Litecoin, whose alternative approach to the proof-of-work algorithm showed that it was possible to stall the entrance of high-powered, industrial players into the mining network. Others—notably Vertcoin, discussed in chapter four—have improved on Litecoin’s model. Vertcoin has avoided Bitcoin’s unwelcome experience, in which the unrestrained competition for block rewards fostered a concentration of computation-heavy, electricity hungry mining operations. There are also various iterations of the so-called proof-of-stake algorithm, which sets a user’s right to validate transactions according to how many coins they hold.

The idea is to give no special advantage to those who own these expensive, single-purpose raw computation machines. This means that people running computers with relatively inexpensive graphic processing units, or GPUs, can successfully compete for a decent supply of coins and that a wider distribution of those tokens is possible. Eventually, chip designers tend to figure out how to make ASICs that overcome this resistance, as was the case with ASIC mining equipment that was specially designed to handle Litecoin’s s-crypt algorithm. But developers of Vertcoin have shown that it’s also possible to create a permanent commitment to ASIC-resistance by introducing something from the real, non-digital world of social organizations: a pact. If the platform’s governing principles include a pre-existing commitment from all users of the coin to accept a fork—a change to the code—that would add new, ASIC-resistant elements as soon as someone develops such a chip, the coin’s community can protect the distributed, democratic structure of a GPU-led mining network.

He made himself enough money to buy a pukka New York pad, and an even more pukka bar, will only employ people if they drink or smoke weed with him, founded a $40 million company and now finds himself under house arrest on money-laundering charges related to the Silk Road. He’s still only 24. Shrem has never even met his business partner, Gareth Nelson. Nelson is an Asperger’s sufferer from Wrexham, who’s now worth millions. Olivier Janssens now flies from London to his new home in Monaco by private jet – paid for in bitcoins. On my hunt for amusing Bitcoin stories, one chap emailed me, saying: ‘I bought $8,000 worth of Litecoin at $2.30 back in June, and when Bitcoin skyrocketed to $1,240, Litecoin went to $52.00. I made $140,000, cashed out $70,000 and bought a new Range Rover. I now drive a Range Rover because of what people laugh at and call fake money.’ But with the failure of companies such as MtGox, you can bet there are many stories that are as disheartening as the above are amusing. The world of crypto-currencies (there are now over 300 altcoins) has attracted all sorts of crooks and fraudsters, as well as those who religiously think they are changing the world.

At $500 a coin, the market cap of Bitcoin stands at around $6.5 billion. All the other altcoins combined amount to about $350,000. Bitcoin has attracted all the publicity. Bitcoin has all the infrastructure and investment. For now Bitcoin dominates the space. But the altcoins may one day come to rival Bitcoin. Litecoin is said to be silver to Bitcoin’s gold. It has faster transaction time confirmation than Bitcoin, making it a better system of payment. It also claims its storage efficiency is better. Like Litecoin, Dogecoin also has faster transaction time confirmation. It is a more inflationary system – there is no limit to supply and it has a faster coin production schedule. Its primary use has been for online tipping and fundraising – you see something you like, you give them some dogecoins. Some coins have been developed which are more private and anonymous.

Ten minutes is also too long for financial transactions where timing matters to get an asset at a particular price, and where latency exposes traders to time-based arbitrage weaknesses such as market timing attacks.6 The immediate solution for entrepreneurs has been to fork the bitcoin code base, that is, to modify the source code by tweaking a few parameters, and to launch a new blockchain with an altcoin in place of bitcoin as incentive to participate. Litecoin is a popular altcoin with a block time of 2.5 minutes, and Ripple and Ethereum are entirely reengineered blockchain platforms that have latency of seconds, not minutes. A sixth dimension is behavioral change in a deeper sense than Netiquette. Today, many people count on their bank or credit card company, even talking with a real person, when they make an accounting error, forget their passwords, or lose their wallets or checkbooks.

I think in a year’s time the road will either adapt, or die.’ Instead of bitcoin, Atlantis initially accepted only litecoin, a new form of cryptocurrency. It was odd that the site didn’t accept bitcoin, which by now had become widely used not only on the black markets but increasingly for legitimate purposes. Small retailers, online stores, activist groups and charities were all hopping on board to accept bitcoin for payment for their goods and services and for donations. The decision to accept only litecoin led to some speculation that Atlantis had a vested interest in the alternative cryptocurrency. One of the founders fuelled that suspicion when they said, ‘Litecoin has a much smaller market share than bitcoin, so we needed to do something drastic to bring attention to the currency and to Atlantis as a way of jump starting the community.’

Or it could have been outright fraud. Or denial. Regardless, lawsuits are pending. What we can do now is be careful not to trust any institution fully. Security for your property is at a premium until the market shakes itself out. Question: What is Dogecoin? Tell me about it. Answer: It’s very cool, or maybe it is a silly fad. The market has to decide. Dogecoin is one of many currencies built on a Litecoin protocol, which in turn was built on bitcoin. There are tens of thousands of so-called altcoins in circulation today. This is market competition at work. They all live in their own ecosphere. May the best coin win! Question: How does the U.S. government classify BTC? Answer: The Treasury Department says bitcoin is property subject to taxation. FinCEN, a bureau of the U.S. Department of Treasury whose mission it is to safeguard the U.S. financial system, says it is a foreign currency subject to regulation.

Answer: As in any sector, there are scams, among which is “pump and dump,” meaning that developers release a coin, fuel the hype, and then sell it. Which ones are real and which ones are not is impossible to say. There are serious risks to such altcoins and it will be some time before the altcoin market becomes stable and reasonably disciplined by market forces. This is part of what happens in any startup technology. Question: Can you tell me about one or two popular altcoins? How are they different? Will they replace bitcoin? Answer: Litecoin is the second most popular cryptocurrency. It is based on a different algorithm from bitcoin, and it has an infinite inflation rate. Others include Namecoin, Dogecoin, Worldcoin, Peercoin, Primecoin, and Feathercoin. All have unique properties and some appeal to people for specific reasons. The Indian nation of Lakota, for example, uses its own coin called Mazacoin. 41 The cryptocurrency market is still in its infancy.

We’re probably going to see meta-currencies whose only purpose is to aggregate the value in all of our wallets for all of our currencies, and allow us to understand value as an abstraction that exists independently of the currencies in which it’s expressed. 7.6. Choosing Currencies and Communities So, that’s a slightly philosophical perspective. That’s why I think it doesn’t matter: Ether is not competing with bitcoin; bitcoin is not competing with Litecoin. They are all means to express the transactional modality we want to use at any point in time to achieve our goals. With this comes a very important and powerful tool. In the choices we make with these currencies, we are also choosing to align ourselves with a community. "Adoption is not simply the act of using the currency; it’s also attaching oneself to a community that has also chosen to adopt that currency."

In 2014, a new digital currency called Coinye West—the name is inspired by the rapper, Kanye West, although he has no direct links with the project—was due to be launched, reputedly for use in the music industry. 41 See 42 For example, “For the 99% who live paycheck-to-paycheck, the loss from demurrage is minimal and would be compensated for in wages and pricing.

They regulate themselves and are governed by the laws of mathematics. 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 or Speculative investors should be aware there are risks involved in the investment and use of cryptocurrencies, such as fraud and security of the platforms. Cryptocurrencies can be electronically stolen, and there is no recourse for the individual.

In this sense, it becomes a tool for existing power to concentrate itself, rather than a challenge to the existing order: as some better economically informed commentators consistently point out, Bitcoin functions much more like a speculative investment than a currency (Worstall 2013; Yermack 2014), although what one is investing in, beyond Bitcoin itself, is not at all clear. 6. The Future of Bitcoin and the Blockchain BITCOIN IS NOT SO MUCH a single software program as it is software written using a model called the blockchain that is can be used to build other very similar programs (related cryptocurrencies like Litecoin, Dogecoin, and so on), but also less similar ones. The cryptographically enabled distributed ledger, and the blockchain used to implement it, advocates insist, have wide application outside of their current uses.[1] We hear (not infrequently) that the blockchain is as revolutionary today as were “personal computers in 1975, the internet in 1993” (Andreessen 2014). Networks built on such technologies are formally decentralized, we are told, in a way that the current internet is not, and thus allow a new range of services and opacity to oversight (and therefore legal as well as unlawful surveillance).

The rediscovery of the need for central banking and government regulation is good for a laugh at the expense of a gaggle of libertarian young men, but it tells us little about the future. Bitcoin is not the only cryptocurrency, however, even though it has the most exchange value in traditional currencies, and has certainly been the most widely promoted. Innumerable rivals exist, based on slight variations of the Bitcoin code, going by names like Litecoin and Quarkcoin. Many of these are opportunistic rivals driven by speculators. They are little better than traditional stock market pump-and-dump scams, in which a few promoters talk up the value of a company so that others will bid up its price, and then sell off their own holdings before the suckers realize what’s happening. For the purposes of this chapter, however, the most interesting cryptocurrency is the one that is generally regarded as a silly joke: Dogecoin.

Light clients are in development and not in general use for Ethereum. In the case of Parity, the light client is marked “experimental” and can be used by running parity with the --light option. Popular mobile wallets include the following (we list these merely as examples; this is not an endorsement or an indication of the security or functionality of these wallets): Jaxx A multicurrency mobile wallet based on BIP-39 mnemonic seeds, with support for Bitcoin, Litecoin, Ethereum, Ethereum Classic, ZCash, a variety of ERC20 tokens, and many other currencies. Jaxx is available on Android and iOS, as a browser plug-in wallet, and as a desktop wallet for a variety of operating systems. Status A mobile wallet and DApp browser, with support for a variety of tokens and popular DApps. Available for iOS and Android. Trust Wallet A mobile Ethereum and Ethereum Classic wallet that supports ERC20 and ERC223 tokens.

For example, the third receiving address for Ethereum payments in the primary account would be M/44'/60'/0'/0/2. Table 5-6 shows a few more examples. Table 5-6. BIP-44 HD wallet structure examples HD path Key described M/44'/60'/0'/0/2 The third receiving public key for the primary Ethereum account M/44'/0'/3'/1/14 The 15th change-address public key for the 4th Bitcoin account m/44'/2'/0'/0/1 The second private key in the Litecoin main account, for signing transactions Conclusions Wallets are the foundation of any user-facing blockchain application. They allow users to manage collections of keys and addresses. Wallets also allow users to demonstrate their ownership of ether, and authorize transactions, by applying digital signatures, as we will see in Chapter 6. Chapter 6. Transactions Transactions are signed messages originated by an externally owned account, transmitted by the Ethereum network, and recorded on the Ethereum blockchain.

Then, during small talk while we were filling out forms, he mentioned that he’d been breached in the recent Equifax hack. That allowed me to say, “Don’t worry, blockchain is going to solve all of that.” He looked up from his papers, grabbed his phone and said, “Well, I have my crypto right here.” That was a damn near perfect assist, a textbook bridge, allowing me to say, “That crypto is how we’re buying this car.” And then, to Eileen’s dismay, we talked crypto. He owned ETH, Litecoin and TRON. I knew that TRON was widely considered a scam. I told him he should look into it. He said, “Yeah, I just bought some because it was only a few cents.” He’s like a lot of noobs who flooded into crypto in 2017, people who don’t understand market cap in relation to the number of coins in circulation, and instead simply hope there is some chance a random coin can rise to twenty thousand dollars, “just like Bitcoin.”

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).

By repurposing the hardware that was originally designed for Bitcoin mining it would be possible to attack hashed passwords with an efficiency that wasn’t feasible before Bitcoin appeared. Having said that though, the Bitcoin ASICs for which details have been published are specifically designed for high-speed mining rather than passwordcracking, so that they would require significant changes to their control circuitry in order to make them suitable for password cracking — it’s not for nothing that they’re called application-specific ICs)71. Two variations of Bitcoin called Litecoin and Novacoin turn another cryptographic mechanism into collateral damage. In this case it’s scrypt, which was specifically designed to be expensive to implement in custom hardware by accessing data spread across a large amount of memory in a pseudorandom manner, a so-called memoryhard algorithm [87]. Unfortunately while this makes scrypt relatively expensive to implement in FPGAs and ASICs, it’s well suited to GPUs, so mining isn’t nearly as hard as it should be.

A side-effect of this Lite/Novacoin mining is that, again, a mechanism designed to protect one type of resource, passwords, is weakened when it’s also used to protect another type of resource, coin scarcity. What’s interesting in these situations is that there’s always been an implicit assumption that, spook conspiracies aside, no-one would bother rolling custom hardware just to crack passwords because there’s always an easier way in than going to that sort of extreme. However if the Bitcoin, Litecoin, Novacoin, and whatever71 In any case your passwords are pretty safe for now since anyone who has an ASIC-based rig is more interested in mining coins than cracking passwords. 312 Design else-coin fans are resorting to custom hardware in order to break schemes that are used to keep passwords safe then it’s now necessary to design password-hashing functions to resist custom-hardware attacks, not because of theoretical devices fielded by secret government agencies but because of actual devices developed for whatevercoin mining.
