In November 1,a man named Satoshi Nakamoto posted a research paper to an obscure cryptography listserv describing his design for a new digital currency that he called bitcoin. None of the list's veterans had heard of him, and what little information could be gleaned was murky and contradictory. In an online profile, he said he lived in Japan.
His email address was from a free German service. Google searches for his name turned up no relevant information; it was clearly a pseudonym.
But while Nakamoto himself may have been a puzzle, trading strategies in binary options creation cracked a problem that had stumped cryptographers for decades. The idea of digital money—convenient and untraceable, liberated from the oversight of governments and banks—had been a hot topic since the birth of the Internet.
Main article: History of bitcoin Creation The domain name "bitcoin. Andresen later became lead developer at the Bitcoin Foundation. This left opportunity for controversy to develop over the future development path of bitcoin, in contrast to the perceived authority of Nakamoto's contributions.
Cypherpunks, the s movement of libertarian cryptographers, dedicated themselves to the project. Yet every effort to create virtual cash had foundered. Ecash, an anonymous system launched in the early s by cryptographer David Chaum, failed in part because it depended on the existing infrastructures of government and credit card companies. Other proposals followed—bit gold, RPOW, b-money—but none got off the ground. One of the core challenges of designing a digital currency involves something called the double-spending problem.
If a digital dollar is just information, free from the corporeal strictures of paper and metal, what's to prevent people from copying and pasting it as easily as a chunk of text, "spending" it as many times as they want?
Bitcoin History: Timeline, Origins and Founder
The conventional answer involved using a central clearinghouse to keep a real-time ledger of all transactions—ensuring that, if someone spends his last digital dollar, he can't then spend it again. The ledger prevents fraud, but it also requires a trusted third party to administer it.
In the process, they would also generate new currency. Transactions would be broadcast to the network, and computers running the software would compete to solve irreversible cryptographic puzzles that contain data from several transactions.
The first miner to solve each puzzle would be awarded 50 new bitcoins, and the associated block of transactions would be added to the chain. The difficulty of each puzzle would increase as the number of miners increased, which would keep production to one block of transactions roughly every 10 minutes.
In 2008, the first inklings of bitcoin begin to circulate the web.
In addition, the size of each block bounty would halve everyblocks—first from 50 bitcoins to 25, then from 25 to Around the yearthe currency would reach its preordained limit of 21 million bitcoins.
When Nakamoto's paper came out intrust in the ability of governments and banks to manage the economy and the money supply was at its nadir. The Federal Reserve was introducing "quantitative easing," essentially printing money in order to stimulate the economy. The price of gold was rising.
Bitcoin required no faith in the politicians or financiers who had wrecked the economy—just in Nakamoto's elegant algorithms. Not only did bitcoin's public ledger seem to protect against fraud, but the predetermined release of the digital currency kept the bitcoin money supply growing at a predictable rate, immune to printing-press-happy central bankers and Weimar Republic-style hyperinflation.
- Pre-history[ edit ] Prior to the release of bitcoin there were a number of digital cash technologies starting with the issuer based ecash protocols of David Chaum and Stefan Brands.

Photo: Michael Schmelling Nakamoto himself mined the first 50 bitcoins—which came to be called the genesis block—on January 3, For a year or so, his creation remained the province of a tiny group of early adopters.
But slowly, word of bitcoin spread beyond the insular world of cryptography. It has won accolades from some of digital currency's greatest minds. Wei Dai, inventor of b-money, calls it "very significant"; Nick Szabo, who created bit gold, hails bitcoin as "a great contribution to the world"; and Hal Finney, the eminent cryptographer behind RPOW, says it's "potentially world-changing.

Laszlo Hanyecz, a Florida how much was bitcoin when it appeared, conducted what bitcoiners think of as the first real-world bitcoin transaction, paying 10, bitcoins to get two pizzas delivered from Papa John's. He sent the bitcoins to a volunteer in England, who then called in a credit card order transatlantically.
A farmer in Massachusetts named David Forster began accepting bitcoins as payment for alpaca socks.

When they weren't busy mining, the faithful tried to solve the mystery of the man they called simply Satoshi. It seemed doubtful that Nakamoto was even Japanese.
His English had the flawless, idiomatic ring of a native speaker.
Perhaps, it was suggested, Nakamoto wasn't one man but a mysterious group with an inscrutable purpose—a team at Google, maybe, or the National Security Agency. I'd get replies maybe every two weeks, as if someone would check it once in a while.

Bitcoin seems awfully well designed for one person to crank out. On December 5,after bitcoiners started to call for Wikileaks to accept bitcoin donations, the normally terse and all-business Nakamoto weighed in with uncharacteristic vehemence.
I make this appeal to Wikileaks not to try to use bitcoin. Bitcoin is a small beta community in its infancy. You would not stand to get more than pocket change, and the heat you would bring would likely destroy us at this stage. At pm GMT on December 12, seven days after his Wikileaks plea, Nakamoto posted his final message to the bitcoin forum, concerning some minutiae in the latest version of the software. His email responses became more erratic, then stopped altogether.

Andresen, who had taken over the role of lead developer, was now apparently one of just a few people with whom he was still communicating. On April 26, Andresen told fellow coders: "Satoshi did suggest this morning that I we should try to de-emphasize the whole 'mysterious founder' thing when talking publicly about bitcoin. Bitcoiners wondered plaintively why he had left them.
But by then his creation had taken on a life of its own. Bitcoin How They're Made Bitcoin's economy consists of a network of its users' computers. At preset intervals, an algorithm releases new bitcoins into the network: 50 every 10 minutes, with the pace halving in increments until around The automated pace is meant to ensure regular growth of the monetary supply without interference by third parties, like a central bank, which can lead to hyperinflation.
How They're Mined To prevent fraud, the bitcoin software maintains a pseudonymous public ledger of every transaction.
Some bitcoiners' computers validate transactions by cracking cryptographic puzzles, and the first to solve each puzzle receives 50 new bitcoins. Bitcoins can be stored in a variety of places—from a "wallet" on a desktop computer to a centralized service in the cloud.
How They're Spent Once users download the bitcoin app to their machine, spending the currency is as easy as sending an email. The range of merchants that accept it is small but growing; look for the telltale symbol at the cash register.
And entrepreneurial bitcoiners are working to make it much easier to use the currency, building everything from point-of-service machines to PayPal alternatives. It's a huge movement.

Wagner, whose boyish energy and Pantone-black hair belie his 50 years, is sitting in his office at OnlyOneTV, an Internet television startup in Manhattan. Over just a few months, he has become bitcoin's chief proselytizer.
He hosts The Bitcoin Show, a program on OnlyOneTV in which he plugs the nascent currency and interviews notables from the bitcoin world. He also runs a bitcoin meetup group and is gearing up to host bitcoin's first "world conference" in August. While bitcoin is "the most exciting technology since the Internet," he says, eBay is "a giant bloodsucking corporation" and free speech "a popular myth.
Through and earlybitcoins had no value at all, and for the first six months after they started trading in Aprilthe value of one bitcoin stayed below 14 cents.
Then, as the currency gained viral traction in summerrising demand for a limited supply caused the price on online exchanges to start moving. By early November, it surged to 36 cents before settling down to around 29 cents. In the spring, catalyzed in part by a much-linked Forbes story on the new "crypto currency," the price exploded.
Bitcoin was drawing the kind of attention normally reserved for overhyped Silicon Valley IPOs and Apple product launches. On his Internet talk show, journo-entrepreneur Jason Calacanis called it "a fundamental shift" and "one of the most interesting things I've seen in 20 years in the technology business.
Andresen, the coder, accepted an invitation from the CIA to come to Langley, Virginia, to speak about the currency. Rick Falkvinge, founder of the Swedish Pirate Party whose central policy plank includes the abolition of the patent systemannounced that he was putting his life savings into bitcoins.

On the so-called secret Internet the invisible grid of sites reachable by computers using Tor anonymizing softwarethe black-and-gray-market site Silk Road anointed the bitcoin the coin of the realm; you could use bitcoins to buy everything from Purple Haze pot to Fentanyl lollipops to a kit for converting a rifle into a machine gun.
A young bitcoiner, The Real Plato, brought On the Road into the new millennium by video-blogging a cross-country car trip during which he spent only bitcoins. Numismatic enthusiasts among the currency's faithful began dreaming of collectible bitcoins, wondering what price such rarities as the genesis block might fetch.
As the price rose and mining became more popular, the increased competition meant decreasing profits. An arms race commenced. Miners looking for horsepower supplemented their computers with more powerful graphics cards, until they became nearly impossible to find. Where the first miners had used their existing machines, the new wave, looking to mine bitcoins 24 hours a day, bought racks of cheap computers with high-speed GPUs cooled by noisy fans.
The boom gave rise to mining-rig porn, as miners posted photos of their setups. As in any gold rush, people recounted tales of uncertain veracity.
An Alaskan named Darrin reported that a bear had broken into his garage but thankfully ignored his how much was bitcoin when it appeared. Another miner's electric bill ran so high, it was said, that police raided his house, suspecting that he was growing pot.
Amid the euphoria, there were troubling signs. Bitcoin had begun in the public-interested spirit of open source peer-to-peer software and libertarian political philosophy, with references to the Austrian school of economics.
But real money was at stake now, and the dramatic price rise had attracted a different element, people who saw the bitcoin as a commodity in which to speculate. At the same time, media attention was bringing exactly the kind of heat that Nakamoto had feared.
US senator Charles Schumer held a press conference, appealing to the DEA and Justice Department to shut down Silk Road, which he called "the most brazen attempt to peddle drugs online that we have ever seen" and describing bitcoin as "an online form of money-laundering. Disciples lobbied to name the smallest fractional denomination of a bitcoin a "satoshi.

And bitcoiners continued to ponder his mystery. Some speculated that he had died. A few postulated that he was actually Wikileaks founder Julian Assange. Many more were convinced that he was Gavin Andresen. Still others believed that he must be one of the older crypto-currency advocates—Finney or Szabo or Dai.
