Ex-Googler Gives the World a Better Bitcoin

    Charles Lee was a software engineer at Google, spending his days hacking networking code for the search giant’s new-age operating system, ChromeOS. But in his spare time, he rewrote Bitcoin, the world’s most popular digital currency.
    Early one October morning two years ago, Lee unleashed his project, Litecoin, onto an online universe that was still coming to terms with its more famous progenitor, and though Litecoin is still firmly rooted in the Bitcoin code base, it has found a place in the world, showing just how strong the appetite is for a new breed money.
    Bitcoin has had an extraordinary run this year, but if you’d sunk your money into Litecoin instead of Bitcoin on January 1, it would have done better. Since then, Bitcoin jumped from just over $13 to its current value of more than $115. Back in January, Litecoin was trading in the $0.07 range. Today, it’s worth close to $2.40. In other words, while it took 200 Litecoins to buy a Bitcoin in January, today it takes only 50.
    Government regulation may put the squeeze on Bitcoin — and perhaps Litecoin too. But digital currency will continue to evolve and grow. It’s what so much of the world wants.
    Although its dwarfed by Bitcoin’s popularity, people seem to like Litecoin because it’s a more credible alternative to the growing list of Bitcoin imitators, which Lee saw as either technologically challenged or straight up pump-and-dump scams. “I wanted to create something that is kind of silver to Bitcoin’s gold,” says Lee, who left Google last month to seek his fortune in the wild west of alternative digital currencies.
    He took the basic ideas behind Bitcoin — a currency created by a pseudonymous character who goes by the name Satoshi Nakamoto — and refined them. Litecoin was designed to pump out four times as many coins as Bitcoin, in an effort to keep the digital currency from becoming scarce and too expensive. It processes transactions more quickly, and discourages the kind of high-volume but very small transactions that have become a nuisance on the Bitcoin network. And it lets regular folks more easily “mine” coins — i.e. provide the online currency system with the computing power it needs, in exchange for digital money.
    The result wasn’t a Bitcoin killer. But it was something that gave digital currency yet another stamp of approval.

    Down the Silk Road

    The Ivory Coast-born son of an entrepreneur, Charles Lee has long had an interest in economics. He describes himself as a gold investor, skeptical of the Federal Reserve. Like his dad, he graduated from MIT, having studied computer science and electrical engineering. And after kicking around in Silicon Valley for more than a decade, he was looking for something new in 2011.
    He found that in Bitcoin: an open-source-software project that seemed to perfectly marry his passions for finance, cryptography, and technology. He first heard about it while reading an article about Silk Road, the online drug shopping mall, and soon, he started playing around with the peer-to-peer software that powers the digital currency. From there, the natural next step was to create his own.
    He released one currency called Fairbrix — but it was a dud, plagued with technical problems. Litecoin was his second effort.
    His Bitcoin fork was worthless the day he launched it, and it was hardly the only Bitcoin alternative out there. But Lee took a different tack from some of the other Bitcoin imitators. He released the currency to the world after mining a mere 150 Litecoins. That meant that the whole world could get in on the currency on the ground floor.
    There was also a bonus for miners, who in October 2011 were engaged in an escalating technology race in the Bitcoin world. Bitcoin miners earned coins by participating in a kind of cryptographic lottery and the folks who could do the most mathematical calculations were rewarded with the most Bitcoins. But as Bitcoin surged in value, people started building complex Bitcoin mining rigs that could do more calculations and therefore earn more Bitcoins.
    Litecoin leveled the playing field, using a technology called Scrypt to lower the advantage miners would get by switching to GPU rigs or custom-designed mining systems.

    Mirror, Mirror

    Thanks to a few small changes to the Bitcoin way, Lee succeeded where others couldn’t. Two years on, Litecoin has started to reproduce the Bitcoin ecosystem is many respects.
    The Silk Road underground drug shopping mall gave Bitcoin a boost, and now Litecoin is accepted at an alternative to The Silk Road, called Atlantis. There’s a company in Utah called Casascius that mints its own physical Bitcoins, and Litecoin has got this too, only the Litecoin version is from Hawaii.
    You may have a much harder time finding a pub in London or a taxi cab in San Francisco that will accept Litecoin, but hey, Jay’s Jerky and Goodies takes them. So does the online tech storeBitElectronics.
    Still, Litecoin is mostly a vehicle for investors who want to get in early on what could be the next wave in digital currencies. But there are a few signs that it’s continuing to strengthen its foothold. Earlier this year, Bitcoin’s most widely used exchange, Mt. Gox, said that it was going to start trading Litecoin.
    To get a sense of how things have changed, consider this. About a year ago, Noah Luis — the guy who mints the Litecoin coins in Hawaii — convinced someone on the internet to buy him a pizza in exchange for 3,500 Litecoins, worth $30 at the time. At today’s valuation that medium-sized meat-lover’s pizza was worth $8,400.
    Luis says he has no regrets.

    In May the project got a boost when Warren Togami signed on. A former software engineer at Red Hat, he’d founded the Fedora Linux project about a decade earlier.
    Togami is now Litecoin’s lead developer and he’s creating a nonprofit foundation to manage the Litecoin software development and advocacy, much like the Bitcoin Foundation.
    And just last month, a Bay Area startup called Coinbase hired Lee away from Google.
    Lee says that he isn’t there to work on Litecoin. He’s written some code that allows Coinbase users to swap Bitcoins via SMS. But he wouldn’t rule out the possibility of Coinbase adopting Litecoin.
    Bitcoin’s story has been a bumpy ride. The currency has crashed and risen from the ashes. Bankers, regulators, and law enforcement agencies eye it with suspicion. In all likelihood, Litecoin will have many similar bumps ahead of it, if it continues ride in Bitcoin’s wake.
    But even if it doesn’t survive, it’s serving an important purpose, says Jerry Brito, a senior research fellow at the Mercatus Center at George Mason University. Bitcoin is “like any other open-source project where people are going to fork it,” he says. “That’s good in that people are going to take it in interesting new directions.”

    Bitcoin upgrade aims for smoother e-commerce



    There's a broad belief that bitcoin might just be the virtual currency that takes off in a big way. To do that, it will need to become a lot easier to use.
    But developers within the Bitcoin community are close to finishing a new layer of code for bitcoin software clients that makes using it more practical for shoppers and merchants.
    "This payment protocol represents a major advance in security and usability," said Jeff Garzik, senior software engineer at BitPay, an Atlanta-based company that builds Bitcoin software tools.
    The protocol will be open source, and it will be up to other developers to implement it in Bitcoin wallets, or software clients used to hold and spend the virtual currency.
    A bitcoin is essentially a secret number that is transferred from one software client to another using a 32-character alpha-numeric address. Although many entrepreneurs are developing merchant tools and software for bitcoin, overall, the system can be clunky and lack a seamless grace.
    For example, merchants can't describe what an invoice payable in bitcoin is for. People also can't give merchants a bitcoin address for refunds. The payment protocol allows for a user-friendly description of a payment request as well as where refunds should be sent.
    Shoppers also need to know the payment request is legitimate. For example, a hacker executing a man-in-the-middle attack could intervene in a transaction, swapping the company's legitimate bitcoin address with his own and irreversibly taking a person's bitcoins.
    To solve that problem, payment requests will use digital certificates, the same kind of security technology indicated by a padlock in a web browser. Specifically, the payment requests will use X.509 certificates, which underpin SSL (Secure Sockets Layer), which encrypts data traffic between two parties.
    While there are many weaknesses in SSL, "it's better than nothing," said Gavin Andresen, chief scientist for The Bitcoin Foundation and lead developer for the Bitcoin-QT client. If a better public key encryption scheme comes along, it can be swapped out in the payment protocol, he said.
    "With Bitcoin, we are trying to get things right from the beginning so the payment process is as simple as it possibly can be and still completely secure," Andresen said.
    The communication between a customer and company will be performed over SSL and will not be part of the so-called "blockchain," the public ledger that shows bitcoin transactions, Andresen said. The payment protocol will not touch the core code that drives Bitcoin's network.
    Andresen and other developers are working on a payment protocol implementation for the forthcoming 0.9 version of Bitcoin-QT, the first Bitcoin software client.
    Future development efforts will rely on the foundation set by the protocol, said Mike Hearn, a software developer who has worked on it. "The real potential will start to become apparent as we add features to it," he said.
    The protocol could eventually be developed to support payment scenarios such as recurring subscriptions, tipping for services-related transactions and authorization and hold situations, used by hotels and rental car companies to verify funds are available.
    "It's really the keystone for many future efforts," Hearn said

    bitcoin now illegal in Thailand


    Deeming bitcoin illegal in Thailand will turn it into a bitcoin black market

    On the surface, everyone knew that it would happen. Some country seeking to control capital would undoubtedly ban or rule illegal a decentralized currency like bitcoin. Now it has happened, but from an unexpected place.

    A baffling decision by Thailand

    If you would have made a guess a week ago about the first country to ban bitcoin, would Thailand even have been in the top five? The top ten? There are a number of autocratic countries in the world that many could have seen doing something like this, butThailand’s decision came seemingly out of nowhere.
    One of the tenets that Satoshi Nakamoto set in his seminal paper on the Bitcoin network was the abolition of third parties being required for payments. The concept of bitcoin is to avoid third parties, “allowing any two willing parties to transact directly with each other without the need for a trusted third party”. This third party, in effect, is a financial institution.

    In Thailand’s case, they did not want Bitcoin Co. Ltd. to circumvent that third party of control. In Thailand, that is the Bank of Thailand. The Bitcoin Co. Ltd. exchange had been trying to get the approval of the Bank of Thailand for some time. But, when they finally understood they would get looped out as the third party, that was enough to hear.

    Could corruption play a part?

    The CIA World Factbook states that the Thai economy has “a well-developed infrastructure, a free-enterprise economy [and] generally pro-investment policies”. Yet in 2012, Thailand had one of the highest prime lending rates in the world, at 7.1%. The prime lending rate is what central bankers use to set interest rates for loans and guide an economy.
    While unemployment figures are very low in Thailand, that interest rate number seems high. This is especially true for a country that suffered a devastating flood in 2011 that left a trail of economic disruption – traditionally banks would provide stimuli to encourage growth. But it may be because corruption is a normal and public fixture in Thailand. This may explain the central banks’ lending policies.
    The world corruption index ranks Thailand 88, which is middle of the pack but fairly low for a country that is well-developed and has a thriving services industry that makes up half of the economy. Those factors are commonly associated with a fairly advanced nation.

    Stopping bitcoin

    Think about this: one of the few bitcoin exchanges in Thailand is now closed because the buying and selling of bitcoins is deemed illegal. Does anyone really think that is going to stop Thai citizens from buying and selling them?
    The existence of Bitcoin Co. Ltd. is enough to show that there are a number of people in Thailand holding bitcoins. It’s entirely possible that Thailand would be a place that if it was legal, a bitcoin economy would flourish. Just because the baht-based exchange is now shuttered does not mean that bitcoins exchanged there are worthless.

    The actions of Bitcoin Co. Ltd. to meet with regulators shows a desire to be a part of the financial system. In fact, no matter what the authorities do, it already is. Yet the recent history of the people of Thailand staging uprisings in 2008, 2009 and 2010 has probably made the government wary.

    Controlling capital

    With what Thailand is trying to do, consider what exchanges in other countries that want to control capital are now thinking. Prior to the meeting with that bank’s officials, Thai officials had signaled to bitcoin.co.th that BTC did not need to be regulated, as it was not part of a money transmission business. It’s clear now that they did not fully understand what bitcoin really was.
    In the United States, many previously suspected that federal authorities would crack down on bitcoin. Surprisingly, that did not happen: in fact, the government decided to instead issue guidelines. Financial technology like bitcoin, they concluded, was not something that they could control. But they could regulate and monitor it.

    Thailand and its banking regulators should think about doing the same. It’s clear that they did not expect the amount of media attention that such a decision would cause. But it seems, given the fact that bitcoin was deemed illegal in the space of one day, perhaps a rash decision might have been made by officials there.

    The bitcoin black market

    Thailand is known for its underground economy and loose legal regulations. If anything, they haven’t killed bitcoin. Actually they’ve made it the number one spot for a bitcoin black market. Jon Matonis, Executive Director of the Bitcoin Foundation, recently wrote in an article for American Banker that trying to make bitcoin go away doesn’t really work. “A throttled and neutered bitcoin in the ‘official’ economy would ultimately enhance its overall effectiveness via increased anonymizing measures and more robust decentralization”.
    The Bank of Thailand’s Governor, Prasan Trairatworakun, has said that it cannot approve Bitcoin Co. Ltd’s business because it’s based on an exchange rate but bitcoin is not a physical currency (and therefore the company is not an actual currency exchange). What they have not realized or accepted is that bitcoin is a currency, just a digital rather than physical one.
    So congratulations, Thailand. You’ve created for yourself a new underground facet of your economy. In your effort to remain in control of your financial system, you’ve created the first bitcoin haven. This to the detriment of everyone working to legitimize and maintain the current state of the bitcoin network.
    Anyone who wants to avoid any sort of regulation that may eventually be placed upon bitcoin, anyone who disagrees with the efforts of the Bitcoin Foundation will just go to Thailand to do their bitcoin business. Because, as in what has happened in this instance, if you don’t understand bitcoin enough or take the time to consider it, how do you plan on stopping it?
    Do you agree with the decision by Thailand to attempt to boot bitcoin from its financial system? What do you think about the concept of a bitcoin black market, a place where regulation isn’t even possible?

    Bitcoin clamp down


    Bitcoin Clampdown Continues As Federal



     Judge Says It’s A Currency

    Wikipedia calls Bitcoin a cryptocurrency (a currency that relies on cryptography), but now it’s official. A federal judge in Texas has declared that Bitcoin is a currency and should therefore be regulated just like U.S. dollars or gold. The ruling represents yet another attempt to regulate Bitcoin transactions, threatening the original purpose of the currency.
    While it looks like a recognition that Bitcoins are worth something, the decision threatens once again Bitcoin’s utopian concept. As a reminder, the Department of Homeland Security recently issued a seizure warrant on Bitcoin exchange service Mt. Gox because it didn’t comply to money transfer regulations.
    Today’s decision goes in the same direction. BTCST, a Bitcoin-based hedge fund, claimed that “the BTCST investments are not securities because Bitcoin is not money, and is not part of anything regulated by the United States,” wrote Judge Amos Mazzant. She then stated the exact opposite of BTCST’s defense:
    First, the Court must determine whether the BTCST investments constitute an investment of money. It is clear that Bitcoin can be used as money. It can be used to purchase goods or services, and as Shavers stated, used to pay for individual living expenses. The only limitation of Bitcoin is that it is limited to those places that accept it as currency. However, it can also be exchanged for conventional currencies, such as the U.S. dollar, Euro, Yen, and Yuan. Therefore, Bitcoin is a currency or form of money, and investors wishing to invest in BTCST provided an investment of money.
    Bitcoin was born on the idea that nobody could regulate it. Instead of having a central bank, Bitcoins are just a chain of characters defined by algorithmic rules. Anybody can try to find new Bitcoins and anybody can verify if it is indeed a real Bitcoin or not. All of this is handled by opensource Bitcoin applications and a few proprietary variants.
    The Bitcoin network is a peer-to-peer payment network, and nobody can intefere with it. The only real value of a Bitcoin comes from its users. Because Bitcoin owners are treating it as a currency, it becomes one. That’s what makes it beautiful and scary at the same time. Yet, Bitcoin creatorSatoshi Nakamoto probably didn’t think that even the U.S. government would treat it as a currency and try to regulate it.
