BEYOND BITCOIN

May 10, 2014



The website of the Japan-based bitcoin trading exchange MtGox disappeared recently amid claims that a massive theft had taken place over two years, emptying its digital vaults of more than $300 million of the digital currency. Bitcoin is a virtual currency that is created from computer code. Unlike a real-world currency like the US dollar or the euro, it has no central bank and is not backed by any government. Instead, its community of users control and regulate it. Advocates say this makes it an efficient alternative to fiat currencies, because it is not subject to the whims of a state that may wish to devalue its money to inflate away debt, for example. Just like real-world currencies, bitcoins can be exchanged for goods and services — or for other currencies — provided the other party is willing to accept them.

It is based on a piece of software written by an unknown person or people in 2009 under the Japanese-sounding name Satoshi Nakamoto. Transactions happen when heavily encrypted codes are passed across a computer network. The network as a whole monitors and verifies the transaction, in a process that is intended to ensure no single bitcoin can be spent in more than one place simultaneously. Users can "mine" bitcoins — bring new ones into being — when their computers run these complicated and increasingly difficult processes. However, the model is limited and only 21 million units will ever be created.

Like any other currency, its value fluctuates. But unlike most real-world analogues, bitcoin's value has swung wildly in a short period. When the unit first came into existence it was worth a few US cents. Its price topped out at well over $1,000 in 2013. There are presently around 12 million units in circulation. Some economists point to the fact that — because it is limited — its price will increase over the long run, making it less useful as a currency and more a vehicle to store value, like gold.

Some commentators say that like many technological developments, the first iteration of a product will encounter difficulties, possibly terminal ones. But the trail it blazes will smooth the way for the next crypto currency. Problems include an apparent vulnerability to theft when bitcoins are stored in digital wallets. This may be what has happened at MtGox. The virtual currency movement also faces legitimacy issues because of the way it allows for anonymous transactions — the very thing that libertarian adopters like about it.

Detractors say bitcoin's use on the underground Silk Road website, where users could buy drugs and guns with it, is proof that it is a bad thing. Some governments, including Russia and China have heavily restricted how bitcoins can be used and a report last month by the International Institute of Finance (IIF), which represents more than 450 banks and financial institutions, said bitcoin's future as a broadly accepted exchange medium is limited.

Yesterday a suspected drug importer who allegedly used Bitcoin to pay his Mexican suppliers has been arrested in Japan, reportedly the country's first case of its kind. Police forces in Tokyo and the southwestern city of Fukuoka teamed up for the operation to arrest Ayumu Teramoto, 38, on suspicion of buying a "stimulant drug" from abroad, a spokesman for Tokyo Metropolitan Police said. It was not clear what the drug was, but the phrase is often used to describe substances such as cocaine or methamphetamine. Media, including national broadcaster NHK, said it was the first time someone had been arrested in Japan for a drug transaction that involved Bitcoin.

While the virtual currency is yet to gain broad-based acceptance in Japan, its profile has been given a boost by the recent collapse of Tokyo-based MtGox, once the world's largest Bitcoin exchange. Teramoto used Bitcoin to buy some 50 grams (nearly two ounces) of the drug, worth 3.5 million yen ($34,500), NHK said, citing police sources.The package arrived at Narita airport near Tokyo, concealed inside a tablet computer, NHK said.

Tokyo police declined to discuss financial and other details of the suspected deal, only confirming that Teramoto used an online service to import the drug via the United States and was arrested on Wednesday. The arrest will likely give support to critics of the virtual currency movement, who say its anonymity and lack of regulation make it ideal for use by criminals. Bitcoins were used by dealers on the underground Silk Road website, where US prosecutors say buyers could use it to purchase drugs and even to organise assassinations.

MtGox is going through bankruptcy proceedings after it admitted that it had lost 850,000 coins, worth nearly $500 million at the time due, in what it blamed on security lapses. The Japanese government has banned banks from brokering Bitcoin transactions or opening accounts holding the virtual unit.
