News it's time for Click. Which would you rather trust with your

This week, Click grabs a fistful of Dollars and turns them into


Bitcoins. This strange new currency is controlled by no-one and


everyone. We will find out if it's an idea that's worth buying into.


He's changed the world once, can he help do it again? We'll sit down


with the inventor of the Web to talk about the good causes


technology is being aimed at now. That plus the latest Tech News, and


a date for your diary in Webscape as we film your schedule with apps


to keep you on time -- Phil. Welcome to Click, I'm Spencer Kelly.


Welcome to the financial heart of London. That's the Bank of England,


the place in charge of this stuff, the UK's finances. Although it's


the job of everyone around here to keep things ticking over nicely, of


course recently they have had a tougher time than normal. The


global economic crisis is hitting some nations really hard. Back in


March as Cyprus's economy teetered on the brink its banks closed down


for two weeks to prevent anxious savers from pulling out all their


cash. But in the last few months, as economies have fallen, a new


currency has begun to rise to fame. Bitcoin. It is the world's first


digital currency. And what's really unusual about it is that it's not


owned or regulated by any bank or any institution. You buy a Bitcoins


with real money at online exchanges. Each Bitcoin is a long you need


string of digits, which is stored on your computer or your own in a


file called a digital wallet. But don't confuse them with things like


Microsoft Points of Facebook credits, these are simply online


vouchers tied to real world currencies with fixed exchange


rates. Bitcoin has its own value. Its own exchange rate, which


fluctuates against other currencies. And also, even though it only


exists online, it actually behaves a lot more like the physical cash


that people trust. A transaction is as simple as me handing you these


notes. It's a guaranteed payment. No middleman. As soon as you hand


over the money, the deal is done. There's a lot of advantages to


taking Bitcoin over the payments, for example PayPal or credit card,


or any other form of mechanism short of a bank transfer. Any other


payment method can be reversed, if someone comes to your site and uses


a stolen credit card, three months down the line after you have


shipped the goods, potentially that could be charged back, you have


lost your goods, and you have reimbursed the card company. With


Bitcoin, all transactions are final. For those whose currencies have


been scripted, like Cyprus, or whose currencies are devaluing,


like Argentinas, Bitcoins have become a valuable investment. But


it isn't risk-free. No-one is controlling the exchange rate, that


means it fluctuates wildly. When Cypriots started turning their


euros into Bitcoins the value shot up. After a cyber attack designed


to manipulate the currency, the value crashed. The story of Bitcoin


is a rather mysterious one. In 2009, someone calling themselves Satoshi


Nakamoto published a paper online saying they had worked out how to


create a digital currency that was completely decentralised. There


would be no meant to create the coins. No authority to regulate


them. No thanks to store them or check if anyone was forging or


copying them. All of this would be done by the computer code which he


released on to the internet. But weirdly no-one knows who Satoshi


Nakamoto really is. All we know is that so far the theory and the


computer code seemed to be working. The way the cryptography has been


implemented is very sound. The vision behind it is remarkable. The


genius. The mathematics behind it is mind boggling. Security expert


Jacques Erasmus is one of those who downloaded the code and became a


Bitcoin miner. It is their machines which police the Bitcoin currency


by verifying the transactions of others. Their job is to spot and


invalidate forged Bitcoin serial numbers and attempts to spend the


same Bitcoin twice. For this service the miners get a


transaction fee, a small percentage in Bitcoins. But the mining


software does a second job. It creates Bitcoins. Creating a new


Bitcoin, with a valid ID number, involves trying trillions of


combinations of digits in the hope of finding one that fits a certain


pattern. It's mathematically very difficult, and intentionally so.


Macca moto Pro Plus programme is designed to you so much processing


power that all the mining hardware in the world will only create a few


Bitcoins between them every hour. This machine has been mining for


about four days non-stop flat out. As you can see over here, it's mind


0.04 of a Bitcoin. It will take you maybe a month, 40 to 50 days, to


mine one Bitcoin. That's not a very good rate of return. There are fast


food restaurants that pay less than that. Definitely.In fact, if you


really want to mine at a decent rate you need to buy tens of


thousands of dollars worth of dedicated hardware. But the fact


that Bitcoin behaves a lot like cash does present some problems.


For one, the only place you'll Bitcoins are stored is in your


digital wallet. How easy is it to steal a wallet from someone else's


computer? At the moment it is very easy. That is one of the main


weaknesses in the structure at the moment. There's a lot of now wear


out their that contains key logging capabilities that are actually


purposefully looking for wallets, Bitcoin wallets, and logging their


associated passwords that unlock the wallet. So if you have those


two pieces, the password and the physical wallet, you can load that


won it up in your own software and empty out. The thing it physical


cash also has another advantage. It's anonymous. There's no record


of who owns what, or who paid to if you don't want there to be. And


Bitcoin ticks those boxes as well. And that means is the currency of


choice on the black market. This is one of several websites offering


drugs and other legal services. You can only access it by using special


and on the Mize Inc software, and you can only pay using the equally


anonymous B?I ? anonymous Bnd it' association with crime that could


be Bitcoin's downfall. One of the reasons people trust state


currencies, for example dollars, is that they have some fundamental


value. You know at some point in your life you're going to receive a


tax bill, and you know the government accepts dollars in tax.


That means everyone trusts there going to be able to use the dollar


to do something useful. Bitcoin, the problem it faces, lots of its


uses are somewhat shady. There is a risk that suddenly trust in the


system collapses and the value could quickly go to zero.


enough enough for Bitcoin to become a real


established currency. Ironically it needs asked to have confidence in


it. Confidence which at the moment is hard to earn -- needs us. If you


use Bitcoin as we would love to hear from you. If you accept them,


treat them, if you've had some stolen, get in touch and share your


experiences. -- trade them. Next up, a look at this week's Tech News.

marketplace in India. Indian retail regulators have prevented Amazon


from selling its own products, but third parties will be able to sell


goods such as physical books, TV shows and movies. India's the


retail market is seen as worth $800 million, and that's with just 8% or


so of the country online. It does face competition from home-grown


company Flipcart, which has been open for several years and is one


of India's top 20 websites. Researchers at the University of


Washington are working on an algorithm that detects tiny shifts


in wifi signals when a user move through it. We seek uses the


changes in signals to recognise specific movements, and can control


everything from a sound system to a coffee maker even through walls.

answer is to start a company like Google. Another is to use your


corporate muscle to get others to do the same. That is what Google


has done. Earlier this year, it launched the global impact


challenge. This week, the results came in.


Google's mission statement. But that mantra does not always


convinced. Just ask British parliamentarians who last month


accused the technology giant of shirking its fiscal


responsibilities to the UK economy or privacy advocates who say that


into our personal lives. However, Google has always placed a high


responsibilities. responsibilities. To that end, it


launched the global impact challenge, asking British non-


profit organisations how they would use technology to change the world.


Last month in a teaching session not unlike the X Factor, the


applicants were whittled down to some winners. The applicants span


the spectrum from a project offering African communities of


greed and safe access to solar power. And a mobile tight form was


a short -- citizens in war-torn projects. Among the judges was Tim


Berners-Lee. He would be a reasonably good person to ask about


how other aspirational world -- world changes could do the same.


Are NGOs using technology as effectively as they could?


reason why this challenge is good is that they are not, typically.


Across the board, there are two problems. The first is that there


are many NGOs, many of them have been around for quite a while. We


addressed this. This is the edge of technology. Show us how you are


aware of that. Because it is not clear. Another way, which is


perhaps more important, is not just about modernising what you have


already been dealing but looking for a new agenda of things that we


can do. Looking at things that will bring in money to become the


business itself. From the point of view of funders, they are not


necessarily looking for money... If the message is that you can put


money in for a few years and then create something that will run


itself out there and sustain itself, that is often an interesting area.


As the inventor of the weather, you have a certain vision as to how it


may develop -- inventor of the internet. Has it gone differently


to what you imagined? Originally, it was supposed to be very


collaborative. The very first browser, that was not just a


browser but an editor. If you found something as you were looking at


the internet that you could improve upon, you could edit it. And you


could save that and think back. The idea was that it would be a


collaborative space so that if we were working on a project, the


project would be in hyperspace. We would build it together and by


showing that project, all of our ideas would be in the space. That


and do not happen. In some way, it has still not become that very


intuitive or collaborative medium. Is it as open as you would like in


terms of the idea of information being freely available across


browsers? When you look at the rich media whether to. A world that we


inhabit, watching videos and all sorts of Material... -- Web 2.0


world we inhabit. With HTML5, we are in a better position. There is


certainly constructive tension between every browser manufacturer,


trying to make something better and smarter. The major browser


manufacturers, the five you have heard of in the West and the five


in China are collaborating very fiercely. And we have got that


tension between the competition which makes people want to advance


and push their own browser head of the other. But you have to have


open standards for the internet to work as well. It is like the forces,


the pressure on the keel of a boat. When it is white, the vessel goes


zooming forward. When it is not right, it goes nowhere. You are not


worried about countries like Iran that say that they will... Or other


systems that may not be entirely compatible with the internet?


not so much the internet but the browsers. The browsers lie on


underlying internet connectivity. What many people did not realise


until the Mubarak regime turned off the internet in Egypt, that was the


first time they realised that it the internet should spend some time


worrying about that. Worrying about who could turn off the internet and


who is spying on you. In countries where it has not been turned off,


someone could be signed when you. A strong government allows people to


communicate and sees the state of the world and allows people to have


dissenting voices. And we have seen when things take a step backwards,


long period of time, I think that openness and democracy are pushing


us towards greater openness and so on. I am hopeful. The genie is out


of the bottle. Now, I would like to introduce you


to my personal assistant. Of course, it is this thing. These days, we


trust smartphones to run more and more of our lives. When it comes to


keeping a diary, what should you do? Stick with the pre- installed


calendar application or go for something third party.


I am Ace slave to my diary and have to consult my smartphone before


Ribery in to do anything. So, I thought I would give some of the


best Callander applications in the world a shot to see if they could


simplify my schedule. This is simple to set up and imports data


from most popular calendars. It uses colour coding to help organise


your life but at $2, I do not think it adds that much to the native


iPhone calendar. Fantastical is $4 on iPhone. I like the look of the


navigation, something that can be fiddly on a small smartphones rain.


You can add defence with context using voice recognition. It will


you can add it events. This kind of virtual assistant feature is where


the power of third-party applications really is for me. Yes,


there are plenty of free options out there but if paying a couple of


dollars is going to simplify my life, I am all for it.


For Android users, there is nothing to pay for this one. It is clear


and simple with no bells or whistles and while it does not do


anything particularly ground- breaking, it synchronise as with


Google calendar, providing a unified experience at cost desktop


and Android devices. If you want to give the native Android calendar a


boost, the agenda which it is a nice, customised add-on with free


and pay to versions that sit on your home screen, keeping you


informed of any schedule entries as well as upcoming birthdays or


especially France. -- special events. Smartphones of


all flavours come with good native might not have to operate at all


assistant assistant features offered by a


third party or have paid Apple. If you use Out?I ? you use Out


calendar, they have their own apps for a seamless a desktop T-Mobile


experience. Windows phone comes with an elegant native calendar but


if you want to go for a different look with some additional features,


Cronos is a good option for a couple of dollars. It synchronise


us seamlessly with your Microsoft account, of course, and lifestyle


Tile. That is the calendar sorted out.
