|Ghosts bitcoins||So, does this mean ghosts bitcoins now have to think of Bitcoin as an asset inexorably linked to the traditional markets — and influenced by centralized moves across things like oil and stocks? The latter bitcoin refers to the cryptocurrency that is used to perform the transactions. As of this moment, 17 million bitcoins are already in circulation; that means almost 80 percent of the 21 million have already been mined. Let's start with some quick definitions.

Since they were encrypted it would take something like a court order to open them up for investigation, and Nakamoto hasn't done anything necessarily wrong. So it's not necessarily our job to try to track [Nakamoto] down.
We're more interested in seeing the bigger trends. So without the key to open that email account, it was closed permanently. Oddly enough, Tanase said, that's how Bitcoins work as well. The system that Nakamoto designed depends on incredibly strong cryptography to lock Bitcoins up. Without something called a "private key," a series of characters that you punch into a keyboard, a Bitcoin is just a piece of code sitting on a hard drive.
And it may not necessarily be your hard drive where your Bitcoin lives. Due to the nature of cryptography, the private key only works to open the coin and not the other way around. Because of this fact, the code for all the Bitcoins in the world is open to all the participants in the Bitcoin economy.
Trade in Bitcoins takes place on all the computers that elect to take part in the trade of Bitcoins through a shared, peer-to-peer network. Nakamoto wrote in his paper that a "timestamp server" would "generate computational proof of the chronological order of transactions.
This creates an incorruptible chain of transactions. The mathematical opening, closing and spending of these coins is verified by all the computers in this peer-to-peer network simultaneously. And so I began to imagine Bitcoins not as a pile of physical things, but as a vast ocean of code that has been created by Satoshi Nakamoto.
The private keys allow people to reach into that ocean and take only the coins that belong to them, and to transfer that ownership however they desire. What keeps Stefan Tanase employed is the fact that the growth of this large, peer-to-peer network has created an unprecedented opportunity for cybercriminals to make money off of Bitcoins.
When someone connects their computer to the peer-to-peer Bitcoin network they are yoking their CPU to the grand wheel that grinds out all the math, the cryptography, that makes the trade of Bitcoins work. And for their trouble they occasionally get tipped in Bitcoins. The process is called "mining" for Bitcoins. Anyone can download a miner, install it on their computer and participate in making the math that underpins the Bitcoin happen, and actually earn Bitcoins in return.
Feed a computer electrons, and that computer prints virtual money. The more computers involved, the faster money gets generated. Tanase said this has given cybercriminals the world over something to do with all the computers they have infected with malware, collections of machines called "botnets. At this moment there are thousands of botnets, big and small, hundreds of thousands of computers earning cybercriminals Bitcoins. High-end graphics cards are better at mining than high-end CPUs, so gaming PCs are actually better at mining coins than others.
Because when you see how much revenue they generate it's really almost totally impossible to do it with real hardware, by buying thousands of graphics cards. Because the Bitcoin has become so popular there are actually more honest miners than cybercriminal miners and that, Tanase said, protects the Bitcoin network from being hacked.
But Nakamoto designed the Bitcoin algorithm so that there are only so many Bitcoins to be mined. Just like in California in , there are only so many stakes in the Bitcoin fortune to be claimed. And as the record of Bitcoin transactions grows, the math needed to keep track of them all gets harder and harder to compute.
The rate of new Bitcoins being created, Tanase says, has already begun to slow. You now need more computing power than ever before to create coins at anything other than a snail's pace. There are few academics better versed on the subject of virtual economies than Yanis Varoufakis, formerly Valve's economist-in-residence.
Today he is on the faculty of the University of Texas, while at the same time serving as the advisor to the general secretary of the Organisation of Economic Co-operation and Development OECD in Paris. Varoufakis is simultaneously the leading economic theorist on the subject of trading virtual hats, and one of the few invited to contribute to an ongoing conversation about how European economies should proceed following the global economic disasters of the mid- and late s.
I needed him to help me make more sense of how the Bitcoin economy functioned, which is good because when I spoke to him he made it clear that he could not care less about the real identity of Satoshi Nakamoto. Varoufakis is a busy guy, but I wanted to know why he took the time to write about Nakamoto in an elegant blog post from late April.
In it, Varoufakis almost casually guts Bitcoin, coming very close to calling Nakamoto a fool, one so in love with his own idea that he can't see the flaws in the system he's created. They are controlled by corporations. The Bitcoin experiment is unique in the sense that no one controls it.
So, effectively, it is a set of tools that allows anyone who uses them to be co-owner of that community. Varoufakis was careful to choose his words as we spoke. These freedoms that members of an economic community have can be for good or for bad, hence "tamper. Getting a loan from Bank of America, Varoufakis said, is not so different as being paid in Bitcoin that someone has fraudulently spent elsewhere. It all depends on the rules you're playing by, and the simulation created by Bitcoin's virtual economy most resembles the rules that existed during what was called the "gold standard.
Playing by those rules, every U. By adding to, or subtracting from, the gold physically held by the Federal Reserve, the U. But there came a time when the Federal Reserve needed more flexibility than the gold standard allowed. President Richard Nixon ended the gold standard in Since that time the U. Without the gold standard, the Federal Reserve can, through various means, create more money in the U. But like the finite amount of gold that used to be held in Fort Knox, there are only 21 million Bitcoins that will ever exist.
It's part of the algorithm that Nakamoto made. Scarcity is baked into the system and is the only lever by which the entire virtual economy is controlled. A system built of numbers has only a number, deaf and dumb, with its hand on the wheel.
And that's where things get interesting. What Nakamoto did by limiting the number of Bitcoins was to revert back to the gold standard. Instead of stifling mineshafts, Bitcoins emerge from computers across the world. But the concept, the scarcity of the monetary vehicle, is the same. And it will keep falling.
When we reach [21 million] it will be as if all the gold from the guts of the Earth has been unearthed. A Bitcoin researcher, in a blog post from April, found recorded in the chain of Bitcoin transactions evidence that one miner got a head start on everyone else in the world.
It's possible, probable even, that Nakamoto has many of the first Bitcoins ever mined, a stockpile of nearly 1 million stuffed beneath his virtual mattress. I had already come to the conclusion that I might never find Nakamoto. But, with Varoufakis' help, it was time to try and get inside his head. Does holding Bitcoins make you more powerful in that virtual economy? To Varoufakis, that's not really the right question.
This is creating a bubble. In Greek and Roman times, change was made by literally cutting coins in half. As the Bitcoin economy continues to grow, there will be the same amount of money shared in the system, and no amount of chopping it up will help it spread far enough.
What will emerge is an entrenched Bitcoin aristocracy, with Nakamoto and others playing the role of feudal lords, high level players who cannot be taken down until they choose to give away their loot. And their only incentive to give up that loot is, naturally, for profit. But if Nakamoto splashed his hoard into the Bitcoin economy now in a bid to take his profits and run, he could poison the well. People would flee from the Bitcoin; the currency would become devalued even faster than when it's mined out.
I began to wonder if perhaps Nakamoto wasn't holding onto his stash to profit. Maybe he was holding it as a kind of doomsday device, the killswitch for the whole Bitcoin experiment. So why would he want to press that button? Clear enough. He left me to draw my own conclusions. Luckily, there was one more person I could to talk to. Eyjolfur Guomundsson is a doctor of environmental and resource economics.
In his position as the lead economist for CCP's Eve Online , he presides over one of the most complex in-game economies ever created. Eve has become the poster child for complex, time-devouring MMOs. It is derided by many as a game so arcane that it plays itself, while others say that its community behaves more like virtual mobsters than any low-level thug whose caricature has waved a gun around a Grand Theft Auto game. Above all else, Eve is a set of virtual businesses that operate within virtual economies using virtual currencies.
That's the hook. That's what makes the game exciting. In a gaming system You can, for instance, sell your hats and trading cards in Valve's Steam Marketplace. But you can't necessarily get that money out of your Steam Wallet and buy diapers or medicine at Walgreens. The only example Guomundsson could think of, or that I could find, is Second Life , whose in-game currency can be exchanged for dollars and vice versa on an exchange called the LindeX.
Almost every virtual economy that exists in a video game is closed in order to allow for different rules and different regulations than you can have in real life. There is no Galactic Federal Reserve controlling interest rates in Eve. There is only a corporation, a real-world corporation in Iceland called CCP, telling you what you can and cannot do with its virtual money. Oddly enough, Eve itself contains two kinds of currencies.
Different rules apply to each currency's economy once it exists in-game, but where those economies meet inside Eve is very much like where Bitcoin meets the U. There is no legal way to cash out. Because we want to keep this closed, because we want to have different rules and different regulations than what you find in real life. While that does not prevent the in-game economy of Eve from growing, it does keep CCP out of the jurisdiction of international monetary organizations.
