A concise and accessible exploration of Bitcoin’s internals and potential impact.
Main topics include:
- Technology: How Bitcoin allows for the secure transfer of unforgeable assets over the internet.
- Economics: Distinct advantages Bitcoin has as a deflationary currency (through a ceiling on the number of mine-able bitcoins) in a world full of inflationary fiat currencies being actively manipulated by central bankers and politicians.
- Potential Benefits to the Poor: How Bitcoin-based remittances, peer-to-peer/micro-finance, and development aid can help the poor route around corrupt financial institutions and inept governments in order to improve their lives.
- Additional Use Cases: Blockchain smart contracts as distributed, uncensorable, self-enforcing contracts; other programmatic aspects of Bitcoin to be exploited.

Economics beyond Financial Intermediation: Digital Currencies’ Possibilities for Growth, Poverty Alleviation, and International Development — [Download PDF]
By Saifedean Ammous
Lebanese American University
Bitcoin is the first technology for the final transfer of digital goods online, facilitating instant global payments without intermediation. Bitcoin’s operation is based on a distributed, decentralized, and transparent asset ledger that acts as an ongoing chain record of all transactions. The system issues coins to reward those who contribute processing power to the network’s operation. The possibilities created by this innovation are significant for the world’s poor, who could skip traditional political and financial institutions and move to digital currencies in the same way they have gone straight to using mobile phones and skipped landline telephones.
- “Through the use of cryptography, Bitcoin brings the scarcity, rivalry, finality, and irreversibility of physical transactions to the digital realm. A digital song can now be treated just like a physical cassette or CD, a rival good that cannot be played on two machines at the same time. This is not just true for music files, but for all kinds of digital data, goods, programs, and, most significantly, currency.”
- “Instead of utilizing a trusted third-party intermediary, Bitcoin is based on cryptographic proof verified by the central processing unit (CPU) power of the total network. As such, Bitcoin can be understood as being to currency what email is to paper mail: an infinitely faster and cheaper digital shortcut for a physical-world activity that has been carried out for millennia.”
- “As the network grows and currency adoption increases, bitcoin’s real-world purchasing power also increases, thus ensuring that the block-mining reward, while decreasing in terms of bitcoin and costing more in terms of CPU, is worth more in terms of real goods and services. This is the most strikingly ingenious facet of Bitcoin’s design: if the network grows, the rise in the currency’s purchasing power ensures that the reward to the computers that run the network increases, thus incentivizing ever-more processing power to be dedicated to verifying the network. The programmed decreasing rate of increase of coin issuance, combined with the fast growth of the network, ensures that miners who operate the network continue to be rewarded for running it as it grows.”
- “The Bitcoin network grows as fast as bitcoin adoption rises, or, in other words, as fast as the bitcoin economy grows. The money supply, however, only rises at a predetermined rate, which is roughly halving every four years, as the block reward declines. Though the supply of the currency is increasing, and will continue to do so indefinitely, the currency’s real purchasing power has increased drastically in the six years it has been circulating. The increase in adoption explains the rise in bitcoin’s purchasing power since circulation started in 2009. The first recorded exchange rate of bitcoins for fiat currency was 1,309.30 BTC for 1.00 USD, offered in October 2009 (Wallace 2011). By July 2015, the exchange rate had risen to fluctuate around 0.004 BTC for 1.00 USD, reflecting roughly a 330,000-fold (or 33 million percent) increase in the price of a bitcoin in US dollars in six years.”
- “Bitcoin exists as a real-world experiment in this inflation-deflation debate. Whereas traditional currencies are continuously increasing in supply and decreasing in purchasing power, bitcoin has so far witnessed a large increase in real purchasing power despite a moderate (but decreasing, controlled, and capped) increase in its supply. If bitcoin’s depreciation rate is measured with respect to the US dollar, it is highly negative, as table 2 shows, averaging a negative 24.5 percent depreciation rate in the four years for which data are available.”
- “While still a technology in its infancy, Bitcoin offers a blueprint for how billions of the world’s poor can partake in international, modern capitalism without having to reside in countries with supportive modern institutions. Bitcoin could be life-changing to those individuals and could also offer credible competition to national monopolies in financial services, currency issuance, judicial systems, and credit provision.”

Trace Mayer, J.D., a long-time Bitcoin Guru and Investor in Bitcoin companies such as Armory and Kraken, explains the network effects that will lead to Bitcoin’s continued success.
From his talk hosted by CRYPSA at LaGuardia Community College – June 29, 2015.
Listen to the audio: http://www.bitcoin.kn/2015/06/crypsa-event-with-trace-mayer/
The 7 network effects of Bitcoin are as follows:
- Speculation — As a novel, cryptographically-backed asset class with the potential for appreciation and high volatility, Bitcoin is perfect for speculators with a high tolerance for risk.
- Merchant Adoption — Merchants will increasingly accept Bitcoin because they can increase their profit margins by avoiding credit card fees and chargebacks.
- Consumer Adoption — Consumers can use Bitcoin to save money at certain vendors. For example, getting a 20% discount on Amazon by spending Bitcoin through Purse. Additionally, consumers can buy things with Bitcoin that they cannot buy (easily) in any other way. Consider: An American can buy Persian rugs or Cuban cigars online despite trade embargoes. Bitcoin increases the efficiency of the economy, particularly in niche areas such as these.
- Security — Merchant, consumer, and speculator adoption lead to a higher price and thus incentivize more miners to participate and secure the system. The decentralized, immutable transaction ledger also serves as a form of Triple Entry Bookkeeping, wherein Debits plus Credits plus the Network Confirmations of transactions increase trust and accountability across the system.
- Developer Mindshare — Bitcoin is a “dumb”, predictable network with simple rules and a publicly-auditable codebase. It is fertile ground for the development of complicated algorithms, machine-to-machine payment protocols, smart contracts, and other tools. Its decentralized nature allows for innovation without permission. Altcoins (such as Litecoin and Ethereum) pose little threat as Bitcoin is already dominant as a store of value and as a medium of exchange in the cryptocurrency space. If you harbor doubts about the importance of this currency network effect — or worry about altcoins overtaking Bitcoin in some other way — I would point you to Daniel Krawisz’ insightful and though-provoking article on the subject: “The Coming Demise of Altcoins“. Ultimately, developers will continue to flock to Bitcoin.
- Financialization — Bitcoin will eat up progressively more of the market share of legacy banking institutions in areas such as remittances, micropayments, peer-to-peer lending, and the exchange of stocks and securities. This process has already begun (consider NASDAQ’s support of Open Assets/Colored Coins for the transfer of securities, NYSE’s investment in Coinbase, etc.). Old money risks dying out lest it embrace new protocols such as Bitcoin.
- Adoption as a World Reserve Currency — Eventually all transactions will be settled on the blockchain, including house titles, stock purchases, car titles, and other monetary instruments and currencies. Network effects one through six culminate in this final network effect. Any newcomer in the realm of cryptocurrency — or traditional currency, for that matter — would need to beat Bitcoin in all seven of these areas. This is unlikely considering the pace of development in Bitcoin Core, the level of investment in Bitcoin companies around the world, the growth in Bitcoin’s user base, and on and on… Further price increases will only accelerate the process. Finally, a speculative attack could dramatically boost the value of Bitcoin almost overnight.
Bitcoin is a strong currency: it thrives on the internet; it frees its users from 3rd parties; it saves merchants money; it is deflationary; its code can be audited by all; its developers work tirelessly to improve upon it; the list goes on. The above-listed network effects can only serve to strengthen it. Competitors beware.
READ THIS NEXT: Speculative Attack, by Pierre Rochard
An excerpt from the introduction of “Speculative Attack”:
Bitcoin will not be eagerly adopted by the mainstream, it will be forced upon them. Forced, as in “compelled by economic reality”. People will be forced to pay with bitcoins, not because of ‘the technology’, but because no one will accept their worthless fiat for payments. Contrary to popular belief, good money drives out bad. This “driving out” has started as a small fiat bleed. It will rapidly escalate into Class IV hemorrhaging due to speculative attacks on weak fiat currencies. The end result will be hyperbitcoinization, i.e. “your money is no good here”.

A Brief Treatise on the Futility of Mainstream Political Action and the Promise of Smart Contracts and Cryptographic Governance
Before I touch on new techniques available to the aspiring political entrepreneur I would like to set the scene with a bleak but informative view of the poverty of our modern, mainly American, political system (not to exclude anyone!).
Public opinion has no statistically-significant impact on public policy in the United States, whereas special interests can block any bill they dislike whilst, more often than not, getting the OK from congress for their own bills.
Unless you are one of the power elite your vote, your political opinion doesn’t matter.
And while the creator of this video would have you believe that there are ways to fix this broken system, I view things more cynically. I would like to make corruption illegal, don’t get me wrong. But I have a feeling that a movement to do so would be co-opted. I see that power elites corrupt and undermine popular political movements and figures on the daily. I see that they control the media and manipulate and sculpt our attention, too. They do this, as Noam Chomsky described, by encouraging lively debate within narrow bands of opinion:
“The smart way to keep people passive and obedient is to strictly limit the spectrum of acceptable opinion, but allow very lively debate within that spectrum – even encourage the more critical and dissident views. That gives people the sense that there’s free thinking going on, while all the time the presuppositions of the system are being reinforced by the limits put on the range of the debate.”
Thus we are diverted from meaningful, profound discussions on a full-range of important issues. Instead, we seem to either A) partake in the spectacle of superficial, divisive debates orchestrated by Puppet Authority Figures on either delimited side of the argument, B) switch to thinking about the next pressing issue, “in other news…”, or C) take hit after hit of interminably-juicy celebrity gossip. The populous is dumb and it has been made dumb with brutal efficiency. But this is not the only reason that I have doubts about the promised, this-time-it’ll-be-different, Represent-Us Revolution, the plan for which you might be led to peruse if you watched until the end of the above video.
Let’s take a moment to review the basic situation here in America, and then I’ll tell you why I am not going to bother with this or any other mainstream progressive reformist movement for political change in the foreseeable future:
- Like they say in the video, politicians have been bought and sold for at least 40 years in the United States. The people that run the country are in bed with the people that run the largest corporations, and only the power elite get their policies enacted with anything more than a jackpot-lottery-ticket-winning success rate. We are dealing with a more-or-less self-sustaining, self-correcting system, a well-oiled machine.
- The American people are uneducated and ignorant of the workings of the machine. In fact, they are prevented from getting an education — at least insofar as they are given no regular opportunities to get exposure to nuanced, unbiased debates on wide-ranging, un-preselected topics. Americans don’t necessarily inherently value intellectual pursuits or learning in general either as far as I can tell. And yet we are impoverished not only in terms of knowledge and understanding…
- The American people are impoverished through excessive taxation (upwards of 50%) and the intentional and unchecked inflation of their currency by the Federal Reserve Banking System; hence, they have not the money or time to care about fomenting political change. Our mental and financial resources are drained in other nefarious ways as well, like through the attention-grabbing, counterproductive drug war.
- America is constantly at war — no, it’s not just with drugs — and the dispossessed (on both sides of the world) are the ones footing the bill.
- We know that if we speak out about corruption, warmongering, taxation, coercion, the broken health-care system, or the destruction of the environment, that we are more likely to be scrutinized by Five Eyes Intelligence Agencies. Although we may not care on average as Americans that we are being spied upon, Edward Snowden and others have worked tirelessly to bring it to our attention. Those that do care and are politically and technically savvy enough perhaps know better now the extent of the surveillance and understand better the design of the Panopticon, feel its chilling effects more profoundly in their bones. It is a scary time to promote and make plans for radical, political and economic deviations from the status quo. But that fear… Perhaps it is the sign that we are entering new territory. So what would moving forward actually look like?
On to the root of the issue of how to — or how not to — create change:
The problem with Occupy, the Tea Party, Revolution.us, and the next dozen yet-to-be-shouted-from-the-rooftops Movements fed up with the status quo is that their solutions regularly rely upon established practices, methods, and institutions. They march, write, phone-in, text, plead, promote, proselytize, fund-raise, and propose legislation. Surely for their supporters, seeing a Movement Member interviewed on the nightly news is exhilarating. And it happens to some extent — perhaps just enough to satisfy this need for a broad-enough-but-still-divisive rhetorical theater in the media as Chomsky described. But my problem with these movements isn’t the limited penetration they achieve into the information-feeding troughs of the average American television viewer or web surfer. My lack of faith in their projects has little do to with their paltry track records for bringing about lasting change, in fact.
My problem lies in the reliance on third-parties in general. By third-parties I mean other groups or individuals on whom the success of the movement, or the achievement of a redress of grievances, relies. Ultimately, if some vaguely socialist democratic movement, let’s say, were to gain power, overthrow and oust the power elites, fix the broken law/financial/environmental/societal system on their own terms, what would it amount to? Obviously we can assume their victory means just what I said, that they’ve achieved what they wanted. But now we’re left with another problem, if not a bigger problem: There is a new power elite, a new administration, a new congress, a new constitution, new third-parties, and new points of failure. Reading Ursula K. LeGuin’s The Dispossessed serves as a firm reminder of the necessity of constant revolution in radical political projects. All these movements, these configurations of human capital, sadly — no matter how virile, impassioned, or disciplined — suffer from the tendency in human-dependent systems towards a centralization of power. Ultimately, this leads to their decay. I — and I believe I speak for many of my readers as well — grow weary of this kind of karmic political cycle, the investment of large sums of energy, getting the ball rolling, only to have its energy siphoned off steadily in an entropic process of attrition and a cutting of supply lines for the movement. So I ask myself if there is a better way to structure our political system. But then I have problems with democracy itself, you see… The whole thing may need to be reworked. But allow me to explain…
What’s the problem with democracy?
It’s not only about centralization and corruption for me. Here’s my problem with democracy: In the first place, in a majority-rule country like ours, at most half of the country (consider especially how few people actually vote) is able to elect the representatives and enact the policies favorable to it. Secondly, those representatives are not bound by contract to deliver on their election promises. And we could even forgive their transgressions — on both sides — those voters who were duped, those elected officials prevented from carrying out ‘the will of the people’ in one way or another. The point being no one need take the blame; this system functions (if you can call it functional) with or without consent, with or without consensus, but more often than not without either in terms of the what the whole country wants. And our media have us believing that this is the best we can do. We swallow this lie and preach it to the heathens that suggest anything else might be better. Meanwhile we swim with sharks in the shark tank, trying to lobby and protest the measly scraps of food we manage to procure as we twist and turn to avoid being eaten ourselves…
Are you telling me there is a way to 1) guarantee that policies get carried out and 2) prove that consent has been obtained from all constituents? Is there a system less vulnerable to fraud, less dependent on malleable and often unscrupulous political intermediaries?
Enter smart contracts. This is what I believe we will use to obviate corruption even if we also succeed in making corruption illegal. So support revolution.us if you want to, but know that we have the tools today to start to programmatically restructure politics or even build alternative, parallel political and legal systems. Cryptographic Governance will allow us to make the shift from being reactive to being proactive in trying to fight corruption. So how does this work, and what are smart contracts?
Let’s let Andreas Antonopoulos, Bitcoin Protocol Champion Extraordanaire, begin. Note this is a highly technical intro; rest assured, further elucidation of the ramifications of what’s being said is forthcoming.
Of course, only in the last 20 seconds or so of this verbose description of smart contracts do the non-monetary applications of this Bitcoin protocol contract scripting language receive mention.
Effectively, what Andreas is saying is that wills, trusts, and other types of agreements can be encoded using this new programming language found in the Bitcoin Protocol to be carried out without (and despite) human intervention given that certain constraints are met.
While we will want to apply this technology to politics, his first example of how a financial transaction can be secured and managed automatically through a smart contract is illustrative:
Basically, amount $XXXX will be transferred from Company A to Company B IF AND ONLY IF:
- Company A signs the transaction to release the funds
- Escrow Company C signs off on the transfer, verifying Company B has fulfilled their end of the bargain and that Company A has the available funds in their wallet
- The transaction is dated after January 1, 2015, and
- The NASDAQ is at 2500 points
A will could be carried out along the same lines, and with it the deeds to an estate transferred, a hitherto encrypted message to the heirs unlocked, and the deceased’s collected private records expunged from all electronic databases, assuming an approved doctor’s death certificate has been uploaded to proofofextistence.com according to predefined criteria.
I think you can see where this is going. Any policy, the rules of governance of any entity, business or political, if they can be defined clearly enough, can be made to execute “no matter what anybody wants to happen.” To paraphrase from Andreas Antonopoulos, the diffuse power inherent in these decentralized technologies is much less corruptible than centralized power. The mayor would no longer keep the keys to the city, but would be given access to them IF AND ONLY IF. You can imagine myriad things as well, I am sure. But just for fun let’s say the mayor gets to use the mayoral limousine IF AND ONLY IF his klout score is above 80, his budget is in the black for the year, and 3 or more proof-of-existence photos of him playing with children in the park have been uploaded to the town webpage during the last 30 days. (A bit silly of a set of definitions, for sure, but that’s what the citizens of Ogdenville decided on!)
This is the world that you and I and our community members can build, leaving the oligarchs out of it. We will not wrest control from the power elites; we will innovate around them (without their permission). This is the future of bitcoin-secured smart contracts and cryptographic governance that I envision.
Take a look at a few noteworthy projects already up-and-coming in this space:
- Counterparty is a platform for free and open financial tools on the Bitcoin network. Counterparty tokens can be used for a wide range of purposes and act as their own cryptocurrency, while still running on the Bitcoin blockchain. Unlike ordinary bitcoin, custom tokens can be used to issue dividends, confer voting rights, as electronic tickets, access to content, and more. Counterparty offers multisignature wallet addresses, which require signatures from more than one Bitcoin private key in order to spend their funds, allowing for flexible consensus-building systems to be built.
- Ethereum calls itself a “platform for decentralized applications” and promises to make writing smart-contracts simple and efficient. One such fascinating project to emerge from the Ethereum-sphere is Augur, a “fully-decentralized, open-source prediction market platform, intended to revolutionize forecasting, decision making, and the manner in which information consensus is collected and aggregated”. Read more about Augur at augur.net. Etherparty is an intriguing user-friendly platform written using Ethereum to make writing smart-contracts easy for non-programmers.
- Blockstream is another project and future platform with similar goals to Counterparty and Ethereum: Making smart-contracts and digital asset management easy and secure. They plan to use a feature of Bitcoin called sidechains to create two-way pegs between bitcoin and other assets or tokens. These assets and tokens in the sidechain can be comprised of anything: digital ballots, contracts, representations of other real-world currencies, the sky is the limit. The main-selling point with Blockstream is the tie-in with Bitcoin’s superior network hashing power — something that makes Bitcoin prohibitively expensive to attack.
- Colored Coins and the Open Asset Protocol is another protocol for tying assets and digital keys to a subset of bitcoin to be transacted over the Bitcoin network. Applications include companies issuing shares in the form of ‘colored coins’, which could then be traded frictionlessly through the Bitcoin infrastructure. Also, a bank could issue colored coins backed by a cash reserve. People could then withdraw and deposit money in colored coins, and trade those, or use them to pay for goods and services. The Blockchain becomes a system allowing us to transact not only in Bitcoin, but in any currency by linking it to a set of colored coins. Additionally, locks on cars or houses could be associated with a particular type of colored coins. The door would only open when presented with a wallet containing that specific coin. This protocol is already being utilized by NASDAQ to “expand and enhance the equity management capabilities offered by its Nasdaq Private Market platform”. This will allow for greater efficiency in the issuance, transfer, and management of private company securities within the Nasdaq ecosystem.
Other noteworthy projects include:
- Lighthouse for decentralized crowdfunding (think: uncensorable, distributed community project donation pages),
- Open Bazaar for decentralized online marketplaces (think: uncensorable, distributed farmer’s markets),
- Maidsafe and Storj for secure P2P information storage (think: Dropbox but no one can spy on you or take down your data; it is distributed in encrypted shards and spread throughout the internet), and
- BitLendingClub and BTCjam for microloans to/from anyone anywhere in the world.
The future is looking pretty bright all of a sudden. But it is incumbent upon us — particularly those of us with the skills and resources available — to help build out these systems and make it happen. We need to maintain and improve upon our already-powerful open-source, cryptographic algorithms. We need to fight to encode privacy and our god-given human rights into the very fabric of the world. Edward Snowden said so himself. It is actually part of what spurred him on in divulging the crimes of the NSA and other government agencies:
“While I pray that public awareness and debate will lead to reform, bear in mind that the policies of men change in time, and even the Constitution is subverted when the appetites of power demand it. In words from history: Let us speak no more of faith in man, but bind him down from mischief by the chains of cryptography.”
[From Glenn Greenwald’s new book, No Place to Hide: Edward Snowden, the NSA, and the U.S. Surveillance State]
Snowden’s goal for us is to create a more free and equal internet. In an earlier interview with Laura Pointras, Snowden explained:
“The shock of this initial period [after the first revelations] will provide the support needed to build a more equal internet, but this will not work to the advantage of the average person unless science outpaces law. By understanding the mechanisms through which our privacy is violated, we can win here. We can guarantee for all people equal protection against unreasonable search through universal laws, but only if the technical community is willing to face the threat and commit to implementing over-engineered solutions. In the end, we must enforce a principle whereby the only way the powerful may enjoy privacy is when it is the same kind shared by the ordinary: one enforced by the laws of nature, rather than the policies of man.”
By implementing these new cryptographic systems, we may move one step further towards what Snowden envisioned: distributed and secure math-based ecosystems that enhance our privacy and allow us to innovate further in all areas — in government, in finance, in communications and journalism, etc. Even if you inherently trust our government — kudos to you for reading this far, by the way — I would argue that the price of non-action here is great: Dictators around the world, future corrupt leaders of America, they all stand to benefit if citizens are denied these tools.
Another of my idols in this space is singer/songwriter/activist Tatiana Moroz, creator of the song, “The Bitcoin Jingle” (see further below). She speaks about the importance of these new kinds of projects in liberating us. In her talk just below, she describes her journey of hope and betrayal, a tale of a loss of innocence, a growing political cynicism. She fell first for presidential candidate Dennis Kuchinich, and then later for candidate Ron Paul, only to be disappointed at their negligible impact (some would say the negligible impact they were allowed to have) in American politics. She later learned about how the Federal Reserve controls and fuels the political machine under which we suffer. But then she found a new source of hope and light in the currency and technology platform known as Bitcoin.
Although I enjoy her talk immensely, concerning the creation of the first pro-artist digital currency, Tatiana Coin — amongst other innovations and insights she shares — it’s not strictly necessary to watch till the end. [Jump to the 19:00 minute mark for the meat of the discussion on smart contracts.] I think you get it. I think you see that people are talking. People like Tatiana, Andreas, and Edward are fired up — and they want you to join in the fight. Greater transparency in government, a reigning in of corruption, proper implementation of secure protocols, the funding of important projects, the re-installation of our civil rights, and perhaps most importantly: the fueling of people’s curiosity and desire to experiment, to live in a wondrous and endlessly-fascinating world. That is their call. And that is the promise of smart contracts and cryptographic governance.
