Bitcoin experts to the crash : that was The craziest year in my life

Someone like Robert Küfner is also from the great Crash not to be swayed. On the Finger he wears a Golden Ring with the Bitcoin Symbol on the head is a wool cap with the word "Hodl". It is a slang term of the bitcoin disciples, originated from a typo, it means "hold on" and not to sell the digital currency, may crash the course. And after the huge Hype surrounding crypto-currencies, it goes on for months down. About a year ago, a Bitcoin was suddenly a 20 000 Dollar value, now he is heading towards $ 3,000. The US star economist Nouriel Roubini has referred to the digital money as the "biggest bubble in the history of mankind". Now it has burst.

"There was a lot of market manipulation," says Küfner, knows the scene for years. He has just written a book about the ten-year history of the Bitcoin. With its cross-Berger company Nakamo.to he himself has speculated for a long time with digital money and became a multi-millionaire. "That was the craziest year in my life," says the 30-Year-old. Although there were earlier extreme price fluctuations, which were in percentage terms, partially even higher. But due to the entry of the so-called "Housewives traders", people who wanted to understand the technology, but in the Boom earn, were pumped at once billions of real money in the market. Such investors have also suffered real losses, while people like Küfner, whose crypto-currencies were suddenly worth a fortune, gains and losses, especially virtual on-screen experience.

Long "crypto winter" expected

That the rates are going up soon again, he will not believe it. "I can't imagine that we will remain a long time in the crypto winter," says Küfner. And yet he believes in the long term, to the idea of a decentralized, digital currency. But above all, the technology behind it. The Blockchain, those of the decentralized database is on the computer network, all users are distributed and information is constant and, for each of the verifiable stores. "We are still at the very beginning, the wave of decentralization is just beginning," says Küfner. The Bitcoin was just the first example of application of a Blockchain, so its like once the E-Mail for the Internet. What was all possible, could hardly be imagined.

many of the Blockchain enjoys a reputation as a universal solvent for a variety of problems of this world. Even in politics, where alternative currencies are viewed with great skepticism, there are numerous Blockchain-Fans. The Federal Ministry of economic Affairs brought to you recently as a means of combating tax fraud into the conversation. "So you could make sure that each point, be sure to understand, who is the owner of a stock," said Secretary of state Christian shepherd. The Federal office for Migration and refugees examines whether one can carry out the asylum procedure authorities across the Blockchain technology better. In each case the current state is saved, other authorities can immediately understand whether there is, for example, positive or negative decisions. Currently, a pilot project is being developed with the foreigners authority and to the anchor-the center of Dresden.

One of the biggest Blockchain-Tests in the economy

In the economy is also a lot of experimenting with the Blockchain to order, there are numerous Considerations and pilot projects in many industries. One of the biggest has just been completed: 36 participants from trade, industry and logistics have tested a digital solution for the documentation of the Exchange of Euro-pallets. More than 500 million of the wooden cargo carrier in Europe are in circulation. Manufacturer, supplier and dealer swap constantly with each other. Because each pallet is a Deposit of approximately 30 euros is located, documented the exchange, with a range seem. Companies such as Dr. Oetker, Henkel, Lekkerland, or dm have therefore developed a digital solution and for two weeks at 20 locations across Germany were tested. "The pallet ticket with Blockchain digitize, and in App mapping," says Christian Grotowsky, Manager of Lekkerland's IT subsidiary. "The exchange process is in several Places more efficiently."

Also Küfner relies on such scenarios. With his company Nakamo.to and Advanced Blockchain, Inc., he helps companies to implement the technology or to develop prototypes. A concrete example is the odometer in your car. Küfner knows, enough people will switch directly to the on-Board computer, and then any number you can enter. "My children will not be familiar with the term mileage manipulation," says Küfner. In the future, the mileage of cars will is unchangeable and for all time in Blockchains stored.

the "block chains don't work"

he doesn't like the concept of Blockchain, and avoids it where it goes. "Block chains do not work in the current Form for the mass market," says Küfner. There is a scaling problem: The most widely used Blockchain Ethereum is quickly overloaded and could not handle for many applications, enough transactions at the same time. Even before you have started in great style to use, is obsolete, the block chain technology, according to Küfners. He speaks rather of the "distributed ledger", which translates roughly as: distributed the cash book. It is an umbrella term for the idea of distributed database networks.

Küfner and his comrades-in-arms tinkering now to a variant with the abbreviation DAG (Directed Acyclical Graph). To explain the differences would take us too far. However, it is similar to another project that will also be developed from Berlin: IOTA. Prominent partners from the German industry such as Bosch or Innogy want to experiment with it, about communications or transactions between machines. Critics say, however, the IOTA was not sure, because the network is truly decentralized. Küfner wants to find in his variant of a solution for this Problem. Whether it succeeds remains to be seen.
