Blockkedjor – much more than just bitcoin

Raindrops shimmer in the cobwebs in our hands between the blueberry bushes and ferns. Septemberhimlen has burst up, the sun can be seen as glitterstänk on the sea beyond the forest. Here, in the scent of moss and the sound of gentle birdsong, sits the programmer Thomas Backlund, and working on his laptop, sittstol and thermos.

He got the nickname ”skogskodaren” when he was five years ago, said his work as a software developer and moved out into the terrain in order to write code.

" I was not at work but realized that as long as I had to pay rent, I could not terminate me. So I said up the apartment and left the job and moved out of the forest.

today, he lives in a house in Nacka, but still goes to the forest to get the focus and the working concentration for a couple of days a week. Backlund now runs his startup, ”Superblocks”, which develops tools for the so-called blockkedjetekniken. The technology is best known for being behind the kryptovalutan bitcoin, but has several other uses.

visited Technology Review, forskarinstitutet MIT's magazine, a refugee camp in Jordan to see how blockkedjeteknik used where. It is fascinating to read, which set up a temporary ”bank” in the camp for migrants to shop for supplies without the papers or cash. Since the transactions on a blockkedja takes place between the two parties, and does not need to go through banks or other intermediaries, the approach of a key programme in humanitarian kriszoner: to be able to enter into financial and legal agreements without a bank account or state identitetspapper, such as undocumented people on the run often lack.

To explain the actual technology behind the blockkedjor is quite difficult. A blockkedja is a kind of database where large amounts of information can be stored. But the information is stored either on a server or in the so-called cloud, but on thousands of computers scattered all over the world at the same time. It makes it possible for people and machines to communicate among themselves, write the contracts and organize themselves, without the need of intermediaries. Imagine a worksheet that has been copied to multiple computers at the same time, where every change or transaction to be saved after all the other parts of the network and have verified the change.

At the World Economic Forum, the annual conference that brings together some of the world's most powerful decision-makers in politics and business, is blockkedjetekniken extensively discussed. According to their forecast, ten per cent of the world's total GDP to be registered in a blockkedja within seven years. And recently they released the report ”Building block(chain) ' s for a better planet”, which lists 65 examples of how technology can be used for a more effective protection of the environment, mainly through the sharing of information on, for example, voting for klimataktioner, the measurement of seas, monitoring system for air quality.

Changes in the blockkedjor recorded permanently, and all users have visibility into the database and changed it. It makes the technology also suitable for, for example, charity and donations, " says Backlund.

– When would transparency make you can make sure that only a small part of the sum goes to the administration, and the remainder to the purpose. It can increase the donor to want to donate if they can get more insight into where the money is going, " says Thomas Backlund.

right now how blockkedjor can be used to secure the democratic choice. The national land survey made in the spring of their first transaction in their digital cadastre based on (. There are also attempts in Sweden to incorporate technology for a better health service.

– It may be about to take your vårdjournaler on (and share them to different instances. It is not only smooth to your data is available for all doctors in Sweden, but also to know that they can protect their data and control who has the right to see them. There are projects for it, to come with their data, and lock them up for the doctor, instead of being stored locally.

Backlund says that it is also being worked on to combine even medical läkardata with the one collected in the hälsoappar: then one can see how health values and heart rate changed over time, so that the experts get more exhaustive information to look at.

The philanthropic idea of redistributing power from the few instances to many users has attracted visionaries to experiment with the young technology. And perhaps that is what you must have in the head: that it is still in its infancy.

– Blockkedjetekniken now is that the compare with was the internet was in 1995, the technology works, but is not finished or optimized. Many people think: ”It's awesome, but I don't know what to have it”, much like they did websites to add up the funny stories in the network's infancy. It was hard to imagine the network 20 years later, and what the social network would be, " says Thomas Backlund.

As with the early internet and the subsequent dotcom bubble, it can make use of hajpkurvan, a graphic picture is made by analyst firm Gartner that shows how a phenomenon moving through the people's intressefaser – from exaggerated hopes to the future significance – and see how blockkedjor right now is to.

will also speculations; in addition to the technical, and everything you can do, even the financial. If there is something blockkedjor and its offspring bitcoin shopped if so is it the money, bullish, and hajp. Reuters revealed in February how the company that for the past few years has changed the name to something with ”blockkedja ' in has seen its shares triple in value. In a column in may, DN wrote:s Katrine Marcal on a particularly noteworthy case: ”Long Island ice tea – which to my knowledge it manufactures soft drinks – changed last year name to the Long Blockchain. What happened? The shares tripled in value in less than a day. And one thing you can say about (: it has nothing to do with iced tea.”

”the Blockchain” has become börsklipparnas buzzword – as much as it has become a joke for the sceptics.

– So here it is with all the new technology that involves money. There are always fortune hunters, in combination with ignorance. In the beginning of the credit card payments on the internet, there were many examples of people who have been ripped off and then it takes a while before the picture becomes more balanced when more serious players are entering, " says Christian Landgren.

He is the ceo of the company Iteam that has taken forward a proposal to the Riksbank for a digital equivalent to cash, kryptovalutan e-the crown, which is based on the blockkedja. He mentions the safety aspect of blockkedjans transactions.

Bitcoin has been in existence for nine years and so far, security has been held, despite a potential profit of several trillion dollars for the one who would succeed in hacking the algorithm. Then you can also look at bitcoins course that has withstood many speculations that it would all be a bubble.

Landgren refers to the hajpkurvan when he's talking about blockkedjor: after hajpens the tip of a sharp valley on the graph, ”lowered expectations in the realistic”. And it follows, hopefully, a maturing technology and growing knowledge – there believe Landgren that we are on the road now, up from baksmällans dip.

the Blockchain is on the way up from the valley that come directly after a hajp. We will start to see the really simple, and secure applications within a number of years.

would be able to have the benefit of blockkedjor. If you distribute a work, in several different countries or continents is needed in the moment is often different agreements for each geographical area, often with several intermediaries. It means less money to the author, who don't have control over the context of the work ports.

working to change it is the british singer Imogen Heap. She has launched the initiative Mycelia used for music makers to keep track of how their works are disseminated and how the royalty will be paid, without costly rättighetskrångel – because (works directly from person to person, is there a way to hijack the intermediate level. The transparency allows one to see who the author is, and what the possibilities are to buy or license the work.

– music makers every year are missing out on millions of dollars because of payments to the wrong kind of people and the right information, if the music is not available, " she says.

– We just need to clearly explain the current problem – the lack of business opportunities, such as getting paid for his work, " she says.

And then add:

– the Key is to not use the word ”blockkedja”.
