Simply about Blockchain

If you have not spent the last couple of years in a hermitage, you’ve probably heard about bitcoins and blockchain. Now, even schoolchildren are actively engaged in mining. Let’s try to figure out what is really blockchain and why everyone is going crazy.

The heart of the matter

Blockchain technology is primarily designed for secure storage of data. Here you can store any important information, from credit obligations to new currencies. The reliability of the entire structure is due to the fact that the register of data is not concentrated somewhere in one place but is distributed among thousands of users around the world. Thus, the very possibility of a hacker attack and some kind of clandestine manipulation of information is excluded.

Cryptography

Actually, the blockchain is just a chain of cryptographically connected blocks. A new block is added to the end of the whole chain, all blocks together are connected by mathematical algorithms. This technology can be used not only to record financial transactions, but for everything that has value.

Hashing

The hash function is a special algorithm that takes input data (any, from image to binary code) and creates from it a code sequence of a specific length. Same files will produce the same hash on the output.

Database

The easiest way is to imagine the blockchain as a kind of database, duplicated tens of thousands of times throughout the network. The database is updated constantly, which ensures transparency and verification of information.

Safer than bank

That sounds ambitious, but according to many experts, the blockchain really became the guarantor of information accounting. The use of this technology excludes the influence of the human factor on the outcome of the transaction: without the agreement of the parties involved, even changes to the general register of data will not be made.

Protection against intrusion

Copies of the database are kept on all participating computers. Decentralised system makes hacker attack impossible. In addition, the hashing process is irreversible, which allows reliable security of personal data: an attempt to change a transaction or an original document will result in a new hash, different from the existing one in the system.

 

Who Created Wi-Fi Technology

Hedy Lamarr. Yes, we should thank that same actress for using the Internet Wi-Fi and GPS. How did it happen?

Hedy was born in Austria in 1913. Being a Jew, she hid her origins in every way. In 1933, Hedy starred in the film “Ecstasy”.  It was the first time in the history of cinema when a completely naked actress was shown. In many countries the film was banned. The parents of the actress worried about their daughter’s reputation. Therefore, they married her to the arms tycoon Fritz Mandl. He was also a Jew. In addition, most importantly, it was Fritz who produced grenades and cartridges for Hitler.

Her husband was very jealous, and Hedy had to leave the movie. But she accompanied her husband to military laboratories and quickly figured out the principle of the action of anti-ship weapons and guidance systems.

Lamarr was not happy with her husband. Once Hedy escaped. The girl ran first to London, and then to the USA. In Hollywood, she was noticed by Louis Mayer, the founder of Metro Golden Mayer.

When radio-guided missiles were adopted, a serious problem arose. Opponents easily violated the guidance of the torpedo, revealing its frequency. Then Hedy Lamarr, together with George Antheil, whom she had met in London, came up with how to protect the torpedo control over the radio (she also assisted with the creation of controlled torpedoes).

Here’s how it worked: a random code was used on the transmitter that would change the transmission channel. At the same time, frequency transitions were synchronized on the receiver. The invention of Lamarr and Antheil became the basis of Spread Spectrum – the connection with the extended spectrum, which is used everywhere. These are GPS and Wi-Fi.

Lamarr was forgotten in the last years of her life. She lived poorly. Moreover, Hedy was engaged in litigation about slander and unauthorized use of her name. For example, in 1998 Corel Draw, a program for graphic design, used a portrait of an actress. Hedy immediately filed a lawsuit, but her claim was dismissed.

The Founder of SpaceX Elon Musk Admitted That He Doesn’t Own Bitcoins

The head of SpaceX and Tesla Inc, Elon Musk, ranked 41st among Bloomberg billionaires with a fortune of $ 21.6 billion, said he does not own bitcoins, with the exception of the 0.25 BTC, which the comrade once sent him.

Previously, SpaceX former employee Sahil Gupta put forward the theory that Elon Musk is the mysterious creator of Bitcoin, Satoshi Nakamoto. Nevertheless, the community was sceptical about this hypothesis. Soon the statement was denied by the billionaire himself.

 

Residents of Arizona will be able to pay taxes with Bitcoin, Ripple and Ethereum

Arizona can become the first US state, whose residents will soon be able to pay taxes using cryptocurrency. The corresponding bill was passed by the State Senate this week.

16 senators endorsed the bill, 13 legislators opposed it, but in the end, a three-vote margin was enough to pass the document. Now the bill will be forwarded to the Arizona House of Representatives for further consideration.

How can it change the life in Arizona?

The representative of the Republican Party Jeff Waninger noted that changes in the state’s tax law will make Arizona a comfortable place to live for users of new technologies. He also believes that in this way Arizona sends a signal to everyone in the US and the rest of the world that in the future the state will be open to blockchain and digital currencies.

At the same time, the representative of the Democratic Party, Steve Farley, warns that the bill shifts the “load of volatility” of bitcoin prices to taxpayers who will continue to use the US dollar.

“It would mean that the money goes to the state and then the state has to take responsibility of how to exchange it,” said Steve Farley.

Nexus Earth Partners and SingularutyNET will Integrate Artificial Intelligence with Blockchain Technology

Nexus Earth Partners has announced a partnership with blockchain platform SingularityNET. They will conduct research on the joint use of artificial intelligence and blockchain technology. As reported on the company’s official website, this cooperation can lead to the creation of a blockchain AI as the most secure and flexible infrastructure.

The head of SingularityNET, David Hanson, stressed that this technology might become the most valuable in the history of mankind.

” It will become the single most valuable technology in all of history. This is the chance for us to change the world together,” Hanson said.

Both companies seek to decentralize artificial intelligence and increase its safety, create technologies that will benefit society, rather than individual corporations and governments. Moreover, they set themselves the task of reducing the cost of artificial intelligence and making it accessible to more people.

The world’s most famous humanoid robot Sofia is based on artificial intelligence, loaded into the SingularityNET blockchain platform.

Canadian VersaBank is Building a Digital Storage for Cryptocurrency

The smallest in terms of assets the Bank of Canada VersaBank announced the creation of a digital vault for cryptocurrency. The new service will be launched in June.

“We’re using what banks are all about — safety and security — only what we’re doing now is saying that physical box in the basement is getting obsolete,” said David Taylor, chief executive officer.

Secure and Super Private Place

To work on the new service, the bank attracted the BlackBerry specialist Gurpreet Sahota. He will lead the team of developers of virtual storage VersaVault. The digital assets will be stored on servers around the world. As in the case of safe deposit boxes, the bank doesn’t know what is inside. In addition, the financial institution will not even have access to the contents of the storage.

“Our differentiator in this market is to be secure and super private,” said Taylor.

The large funds have already shown interest in the novelty. The cost of services in the bank has not yet been determined, but it will not be “cheap”.
