What is Bitcoin?

4 stars based on 36 reviews

No prior knowledge required! Bitcoin was first described in a 9-page research paper posted online in under the pseudonym Satoshi Nakamoto. The paper, titled Bitcoin: A peer-to-peer electronic cash systemcovers a broad variety of topics, such as financial economics transaction costs, trusted third-parties, money supplynetwork engineering distributed decision making, data routing, cyberattacksand cryptographya branch of mathematics interested in establishing secure communications to facilitate peer-to-peer, open, and borderless transactions between users.

And this is the primary reason why, until today, bitcoin has remained difficult to understand for most of us. If you want to learn more about particular aspects of bitcoin, you bitcoin easy definition of capitalism click the hyperlinks throughout the text and consult the supplementary materials listed at the end of each section.

This is of course optional. You can get a solid overview of bitcoin in one hour without doing any of this. The bitcoin paper essentially describes a software system enabling people to conduct secure peer-to-peer online transactions without relying on banks or payment companies.

Satoshi Nakamoto whose real identity is still unknown has then progressively withdrawn from the project, and sinceit is an international bitcoin easy definition of capitalism of developers who regularly upgrade the bitcoin software used by all the stakeholders in the ecosystem.

Bitcoin fundamentally transformed the way value can be stored and exchanged. With early VC investments comparable to that of the Internet, hundreds of millions of dollars have continued to be invested in start-up firms that build their products or services on bitcoin. Bitcoin and its underlying blockchain technology have also become a focal point for the financial technology FinTech industry, which broadly entices financial institutions, governmentsand central banks across the world.

While bitcoin is the first decentralized cryptocurrency ever implementedseveral aspects of the bitcoin project have their roots in research conducted in the ss.

Several companies attempted to create e-currency systems in the s—none of them in a decentralized way—and all of them failed. This is one of those rare moments in history where a social scientist actually makes an accurate prediction about some significant aspect of the future! Bitcoin is to blockchain, what email is to the Internet. To date, the most basic bitcoin easy definition of capitalism prominent application of bitcoin has been its use as a secure decentralized payment system.

The following video explains how this works:. The By removing the need for a trusted third-party, bitcoin makes it possible to send international payments without relying on banks e.

HSBCcredit card companies e. Visaor payment processing firms e. To understand how, we need to get a good grasp of the bitcoin technology. It is that time in the bitcoin crash course when we need to take a look at the basic features of bitcoin technology, and based on that outline potential applications beyond payments:.

We now begin to understand how bitcoin works under the hood, and how its features offer a distinctive take on the notions of trust and ownershipwith potentially far-reaching implications. Bitcoin essentially relies on five interrelated technological building blocks:. Miners group transactions into blocks added to the blockchain. It will still shed additional light on how bitcoin really works, so try to watch it till the end!

So far, this bitcoin crash course has bitcoin easy definition of capitalism light on bitcoin easy definition of capitalism crucial aspects of bitcoin. First, bitcoin is a network of computers that relies on cryptography, a peer-to-peer protocol, and a scripting language to maintain a shared, transparent, permissionless, append-only, decentralized ledger of transactions. Second, bitcoin allows for transacting digital assets possibly tied to real-world assets without trusted third-parties.

Not every feature of bitcoin represents an innovation though. Cryptography, peer-to-peer networking, or digital signatures existed long before bitcoin. Bitcoin offers a practical solution to this theoretical problem. Click on the image to download the full paper establishing the Fischer-Lynch-Paterson impossibility theorem. To bypass this theoretical problem, bitcoin does two things. These are the costs of achieving distributed consensus in a network with no central authority, and wherein some users are dishonest.

Put differently, since bitcoin works without bitcoin easy definition of capitalism to trust every user in the network, bitcoin is said to enable trustless transactions. In fact, computer design is premised on the ability to easily copy and transfer digital files. But things that can be copied without constraints are, by definition, not rare, and this affects their value—usually negatively. One of the primary reasons why bitcoin has value is because it is scarce, and that scarcity is protected by design.

Besides, the bitcoin blockchain enables tracking who owns what at any point in time. The music industry lost billions in revenues when music files became easily replicable in the digital world that is, when they ceased to be scarce. Imagine what a technology like bitcoin could have changed in this context! Bitcoin is not a corporation. It does not have shareholders, managers, or even employees. The bitcoin ecosystem is best described as a community.

Bitcoin users are individuals who use bitcoin to make payments or simply hold bitcoin as a speculative store of valuehoping to make a profit. There are many discussions about whether speculators are a good or bad thing for the community as a whole, but they are beyond the scope of this bitcoin crash course. Eight years down the road, we have seen ups and downs in the journey of bitcoin adoption.

The bitcoin easy definition of capitalism trend appears to be optimistic, considering the time it takes for a revolutionary technology relying on network effects to reach the critical mass for everyday adoption. This is to say, the general public will have to feel comfortable using bitcoin for daily transactions like how we use cash issued by the central banks today. Governments have been investigating different possibilities, and overall, more and more governments are taking a positive stance on bitcoin e.

As with any cutting-edge innovations, it takes the flexibility for emerging use cases to take shape and be clearly seen. Interestingly, the video also shows that, while it is possible to use bitcoin without involving any third party, in practice, many users do rely on third-party service providers to buy, sell, store, or exchange bitcoin.

Bitcoin has created an industry encompassing subsectors such as wallet provides, exchanges, payments and mining.

An important source of funding has been from the venture capital firms. Sincemany have noticed that the bulk of VC investment has shifted from pure-play bitcoin startups to blockchain technology startups—that is, startups not necessarily relying on the bitcoin currency, but instead on potential applications of the underlying blockchain technology. There are many different types of third-party providers in the ecosystem. They are typically private, for-profit firms funded by Bitcoin easy definition of capitalism.

Cryptocurrencies such as Ethereum which focuses on the ability to support smart contracts, and Monero which features better privacy provide novel solutions to address the old intermediary problems. Bitcoin mining is a computing power intensive process that is more effectively performed by specialist equipment. In addition, miners pool their computing power together to increase the probabilities of winning the rewards. Mining companies thus were established to fulfill these two categories of demand: Cloud mining has also emerged as another option, whereby anyone can pay for the service provider to mine and bitcoin easy definition of capitalism rewards.

There are two general concerns the community has about mining pools. Today, most bitcoin are mined in China check this for more on how a mining facility looks like. The most recent halving event took place in Julyby which bitcoin easy definition of capitalism reward went down from 25 to The problem is, mining is costly in hardware, electricity, and rent and thus only profitable when the bitcoin price bitcoin easy definition of capitalism high enough to cover these costs.

This is the bitcoin easy definition of capitalism risk miners will have to take. What do they do exactly and how can one bitcoin easy definition of capitalism the team? Listen to a core developer talk about his job:. Now, you may be wondering… How many core developers are there? Less than fifty developers in the world are in charge of major developments. Disagreements can emerge in the bitcoin community. The most imminent one is the scalability issue. As the bitcoin transaction volume increases, the 1MB block size limit has created a bottleneck for the bitcoin payment processing speed.

Over the past two years, the bitcoin community has had heated debates on bitcoin easy definition of capitalism to scale the bitcoin network going forward In Julythe bitcoin scalability debate settled on the Bitcoin easy definition of capitalism proposal, which increase the block size to 2 MB by separating signature data from bitcoin transactions and by creating a second layer of solutions. Merchants have several incentives to start accepting bitcoin.

First, the bitcoin user demographics are bitcoin easy definition of capitalism attractive —they tend to be tech-savvy people in the higher income brackets. Second, settling bitcoin payments at the point of sale is mobile-friendly, transaction fees are between 1 and 2.

Third, settlement takes seconds including internationally when bitcoin easy definition of capitalism the services of a bitcoin payment processor, which is faster than credit card payments. As long as bitcoin payments remain private, no specific regulation applies in most countries.

However, tax offices have provided guidelines on how to declare capital gains realized in bitcoin. But as soon as third-party businesses are involved which is most of the timebitcoin is actually heavily regulated and a number of enforcement agencies are involved. Some would bitcoin easy definition of capitalism that bitcoin bitcoin easy definition of capitalism in the U.

National regulators have been experimenting in their approach to bitcoin. InJapan further approved the acceptance of bitcoin in retail as a legal currency, and eliminated consumption tax on bitcoin transactions. The Japanese government is officially supporting the use bitcoin as a payment. Due to these policy changes, trading is expected to soar even further from the bitcoin easy definition of capitalism status. Overall, regulators are showing more flexibilities in this regard.

Bitcoin regulation in selected jurisdictions. Bitcoin has started strong from the beginning of A few milestones for bitcoin have been reached so far. For instance, bitcoin is now larger than quite a few fiat currencies in market cap e. Bitcoin has also grown significantly in investor as cryptocurrencies gain wider awareness and acceptance. We have also seen lowered volatility in bitcoin price in bitcoin easy definition of capitalism

The digital currency Bitcoin has hit the headlines in recent times for its novelty, as well as for its phenomenal rise in price over the past few years. But how much of the Bitcoin sensation is hype, and what is the reality? Bitcoin is a method of payment and a digital currency that was launched in One of its key features is its decentralised structure that prevents regulation of the currency by a central authority or bank.

It is this aspect of Bitcoin that is trumpeted by utopian libertarians who see it as the embryo of capitalism without regulation or control, a dream that is already being scuppered by the realities of the modern world.

Others see Bitcoin simply as an opportunity to get rich quick and then get out before the bubble bursts, and in that sense Bitcoin paints a microcosmic picture of the nightmarish short-termism and irresponsibility that is the hallmark of capitalism in decline. It is hardly surprising that such a phenomenon should take off in the midst of a global crisis of capitalism.

According to some, the technology pioneered by Bitcoin and other so-called crypto-currencies is potentially game-changing when it comes to online transactions, with as much potential for a revolution in payment processing as Napster was able to achieve with music downloads. However, what is already becoming clear is that this technology can never be used to its full potential under capitalism: The most hardcore Bitcoin enthusiasts insist that the crypto-currency hails a brighter future free from human error and untrustworthy governments.

The economic collapse in Cyprus in , which led to the government seizing a percentage of the deposits of the wealthiest accounts in Cypriot banks, was seized upon by Bitcoin developers who pointed out that such a situation would never arise if only those deposits were held in Bitcoins, out of reach of governments who need bailing out when crisis hits. Similarly, supporters of Bitcoin point to the eye-watering quantitative easing that is being carried out, most notably in the USA, and the damage and instability the tapering of that easing is causing in the emerging markets, as evidence of the irresponsibility of central banks when it comes to managing currencies.

This decentralised setup makes it impossible for one person or entity to control the currency; instead any changes to the network have to be agreed upon by all those who work to maintain it.

This may look good on paper, but the proof of the pudding is in the eating; and in the complex and dynamic reality of the modern economy Bitcoin seems to be leaving libertarians with an unpleasant taste in their mouths.

The value of a bitcoin is incredibly volatile. Recently it increased in value by 60 times over the course of a single year, reaching over USD 1, in December , only to have fallen to around USD today. It goes without saying that such a volatile commodity makes for an extremely bad currency.

Bitcoin enthusiasts insist that the currency will stabilise given time and wider adoption of Bitcoin, but this seems unlikely. The use of a commodity as a currency gives it a two-fold function. Firstly it makes it into the universal equivalent in which the value of all other commodities can be measured. And secondly it makes it into a means of exchange. These two functions are closely linked. Historically, precious metals like gold have been used for this task because they concentrate a lot of value - i.

This is possible because gold, as a rare metal, requires a significant quantity of socially necessary human labour to extract and form into a tradable commodity. It therefore does not require much gold to reflect the value of large quantities of other commodities, making it easier to transport and thus facilitate trade.

Its physical property of durability also recommends it as a means of exchange. What matters when it comes to currency as a means of exchange is not the intrinsic value of the currency but the ease with which it can be moved around. The function of being a universal equivalent in which all value can be measured must still be fulfilled by a commodity that has a real value i. For this reason, any tokens that are used as currency must be backed up by a commodity of real value, i. Going into a high street bank and demanding the equivalent in gold of a ten pound note is not likely to get you very far.

So where does Bitcoin fit into all this? Clearly it is a means of exchange, but it is not backed up by a government and a national economy. Bitcoins do not have an economic anchor and so their value is entirely driven by speculation and subject to the whims of investors.

Such an empty currency really cannot be considered a currency at all as it is entirely crippled by contradictions. There is an upper limit on the number of bitcoins that will ever be produced, which has been set by its developers, and which will not be reached until the early 22nd Century. But this is entirely arbitrary. Marx points out that when it comes to money, the amount in circulation in a given economy is determined by the sum of all the prices of the commodities being exchanged, divided by the speed at which those commodities change hands.

In other words, the amount of money needed in circulation for the economy to function properly cannot be set arbitrarily or on a whim, but is determined by the strength and development of the economy as a whole. Bitcoin is not tied into an economy; in fact it is extremely hard to find real commodities to buy with bitcoins, and therefore the number in circulation is entirely divorced from the real world. It is this abstract attitude to the concept of money that seems to plague every aspect of Bitcoin.

Strangely for a man so closely linked with the world of social networking, Winklevoss seems unable to grasp the fact that money is, by definition, social. It is not possible to separate money from the societies that use it, nor to place it outside of the influence of the real people who use money throughout the wider economy. This is the reason, historically, why central banks arose in the first place — not as a dark conspiracy forced on society by incompetent governments, but as a result of the development of trade using a universal equivalent.

In that sense it is a socialising instrument and can no more be separated from society and placed under mathematical control than trade as a whole could be. Bitcoin transactions are currently illegal in Russia, and Chinese banks have been banned from handling Bitcoin transactions. Singapore has classed bitcoins as goods rather than currency, but Britain has scrapped plans to charge VAT on the mining of bitcoins. The USA is reviewing the situation and has yet to indicate what its stance in relation to the crypto-currency will be.

The status of Bitcoin at the moment is clearly not that of a legitimate currency, but it is also obvious that governments are not entirely sure in what way they should classify it. Could Bitcoin ever become a bona fide currency as its advocates argue?

This is a classically abstract and utopian idea. Purely hypothetically this idea may be true, in much the same way that if everybody simply stopped obeying the law then the law would no longer exist. But an idea is not correct simply because it looks good on paper; its validity is proven only by its capacity to be implemented in practice.

It seems highly unlikely that Bitcoin will gain wide acceptance for a number of reasons. Governments and central banks are unlikely to give up their control of national economies, precisely because that is the method by which they seek to regulate the economy. The good sense and impact of this policy on millions of workers around the world has been discussed elsewhere. It is important to note for now that this is viewed by the bourgeoisie as one of the only solutions they have to the crisis.

Any threat to take that kind of control out of their hands to be dispersed through a decentralised structure is going to be met with the full weight of the bourgeoisie and their state apparatus in opposition to such an attempt. For Bitcoin to be widely adopted it would have to offer something better for people than the currency they already use. This may be an attractive prospect for all the wealthy Russians who lost money when the crisis took hold in Cyprus, but for the vast majority of people Bitcoin, as a method of exchange, offers them nothing because they have no money to exchange for commodities in the first place.

Whether we use Bitcoin or Dollars, it makes no difference if we have none of either. Bitcoin as a currency has no impact on the ownership of the commanding heights of the economy and therefore is of little interest to the vast majority of ordinary people.

Also, already this year USD 2. Some of these thefts have been possible due to bugs in the software that supports the bitcoin network, demonstrating the vulnerability of an entirely digital currency.

Because Bitcoin transactions and owners are anonymous, trading with Bitcoin is akin to handing over a bag of cash down a dark alleyway; and storing it is like keeping wads of cash in a shoebox under your bed. Even firms who specialise in keeping bitcoins safe seem unable to protect themselves against hackers, so to expect everyone to have the technological skill to protect their computers sufficiently to avoid the theft of their life savings is frankly ridiculous.

Banks spend billions protecting themselves from theft; for Bitcoin to be widely adopted would require similar efforts on the part of each and every member of the public — such a situation would be impossible. Making Bitcoin a currency is not simply a case of declaring it to be so and watching it take off.

At the moment it clearly is not a currency, given its abstract nature and lack of an economic anchor, and its prospects for becoming one are slim.

It exists in a world that already has historically evolved and established currencies, compared to which it has little to recommend itself for the majority of people. On top of that, at a time of economic crisis when governments are doing all they can to regulate their own money supply, and with increasingly nationalist inclinations as is inevitable at a time of capitalist crisis, a decentralised, international currency will be met with firm opposition if it tries to begin to tether itself to any kind of real economic activity.

Bitcoin is supposed to prove that building a system that runs perfectly well without centralisation is possible. This is yet another fundamentally mistaken idea of how the economy works. Bitcoin was set up as a perfectly decentralised system, but to expect it to begin working on a capitalist basis and remain decentralised is pure fantasy.

Everything changes and nothing remains the same — under capitalism that change takes the form of concentration of capital and, in a capitalist system where capital equals power, that means the centralisation of power in the hands of a smaller and smaller number of people.

Under capitalism centralisation is inevitable. As has already been pointed out, central banks are not the result of conspiracy or accident, but the inevitable product of economic development and trade.

The utopians behind Bitcoin dream of giving people power over their own lives; but long as capitalism exists that will never be possible. We should not see centralisation as the enemy, but rather the class that controls these centralised institutions.

Marx points out that, when it comes to tokens as currency, those tokens only have a use-value if they have an exchange value. In other words, unless those tokens are accepted as a valid currency then they have no useful function whatsoever and therefore have absolutely no value even if human labour has gone into producing them. Why is this happening? This is a classic example of a speculative bubble. Bitcoin is new, fashionable and often in the news. Its cult status, anti-government aura and lack of clear regulation or understanding of it by the authorities makes it attractive to investors looking for somewhere to make some quick cash.

Because it does not have an economic anchor it is very susceptible to waves of speculation that can have a snowball effect in pushing the price of bitcoins up — hence a fold increase in price over the course of a year.

Of course, the same factors that mean the price can increase rapidly also mean that it can collapse in the blink of an eye. News of hacking or other malfunctions have caused Bitcoin prices to take a tumble multiple times in a short space of time.

Mere rumours, or rumours of rumours, can cause jumpy investors to abandon ship which, without any real value to back it up, has the capacity to cause Bitcoin prices to collapse entirely, wiping out fortunes in the process. Investing in Bitcoin is therefore a risky but potentially profitable business. At the present time this is a rare thing. The reason for this is the crisis of overproduction that is paralysing the global economy. In the last period capitalism has been extended well beyond its limits, primarily thanks to the vast expansion of credit.

Working people, who are paid less than the value of the goods that they produce, were able to borrow money to allow them to continue consuming. But this can only go so far, and for the last five years the economy has been suffering the hangover for the previous period of wild borrowing.

The result is that capitalists look to speculation and gambling on the stock markets to make their money.

In such circumstances, Bitcoin is an attractive prospect. It holds next to no real value, but it is something that can be invested in, traded and made a profit out of. Speculative bubbles such as this are prone to burst, and Bitcoin is extremely volatile and has seen its price rise and fall dramatically since its conception.

Normally such volatility would put investors off, with most looking to invest in something with more stability and a higher likelihood of a good return.
