The founder of Ethereum Vitalik Buterin warned investors about the risks existing at the cryptocurrency market and advised them not to invest all their savings in the new asset class.
Buterin not for the first time points to the community’s obsession with making a profit on the cryptocurrency market, as it, in his opinion, doesn’t contribute to achieving something real meaningful for the industry.
Earlier, Bitcoin Core developer Gregory Maxwell criticized Vitalik Buterin for supporting the “rescue hardforks” to restore stolen or frozen funds. Maxwell stressed that in this case the system has already failed.
If one day the micro robots will start travelling inside our bodies, they should be able to deal with obstacles. Scientists from Purdue University created a new magnetic robot called microTUM. It moves overturning and can overcome hollows and mounts in wet or dry environment.
Key features of device
Having dimensions of 800 microns in length and 400 in width, the magnetic robot looks very similar to the micro robots of the Max Planck Institute engineers. Both prototypes have elongated magnetic tips, which allow them to control the magnetic field. The robot is available for carrying medicines or other loads. It can carry them right to the organ where they are needed.
The human body is a diverse and inimical environment. Frictional forces can impede the movement of the bot. Moreover, biological fluids increase resistance. The engineers report that overturning is crucial for μTUM mobility. This requires a strong magnetic field. However, the minibot always keeps one side on the surface and can handle even steep slopes.
Having checked the device in various environments, the developers assured that the μTUM works well under any conditions. For instance, the oil slows it down. On the contrary, it allows to climb mounts and slopes with an angle of up to 60 degrees. Moreover, the micro bot moves faster outside due to the ability of rock climbing.
In future, μTUM can finally become an application for medicine delivery. Prior to this, the team is planning to give it a new management system based on machine vision, for more accurate movement and development of a non-magnetic mode of motion.
English mobile Internet consultant Terence Eden reported on his official Twitter page that in London a billboard was hacked. The hackers installed a program on the device and started mining cryptocurrency using a computer that ran a billboard.
Terence Eden photographed a huge advertising screen, which took almost the whole wall of the London shop. It is noteworthy that the Windows OS was installed on the computer that controlled the advertisement.
On the photo you can see the desktop of the computer with a lot of icons. One of the open programs was the NiceHash program – a program-miner for old computers. It is also known that the purse where the cryptocurrency came was started with the symbols 3Jgi6. In his message Terence Eden suggests that thanks to this information his “smarter” subscribers will be able to find out to whom it belongs. In addition, it is not known whether the software for the mining was installed by the store employees themselves or someone else.
The four–legged robot SpotMini developed by Boston Dynamics, which was completely updated in November last year, received a hand manipulator that allows it to perform many tasks, in particular, to open doors. Now employees in BD should be careful for the robot not to escape.
Boston Dynamics demonstrated its four–legged SpotMini for the first time in 2016. A fully electric robot with a height of 84 cm has a precise mechanics of animals. Moreover, it contains a lever with a five–degree manipulator. The latter receives signals from a set of sensors. It includes stereo cameras, IMU, as well as position and force sensors. Last time SpotMini showed how it was running along the open country with incredible agility as well as smooth movements. But the recent presentation gave even more horrible and exciting image of these machines‘ updated abilities.
One robot comes to the door, looks on it, and then waits for another robot to open it. The updated Spotmini easily stretches its “hand” to the door, open it, and politely holds it while the “comrade” enters the room. This video impressed a lot. The way they move and “behave” can not but frighten.
Breaking in the Italian BitGrail Exchange last week and stealing of $ 17,000,000 XRB sparked an active discussion between prominent representatives in society.
Blockstream co-founder and leading Bitcoin Core developer Gregory Maxwell criticized the founder of Ethereum Vitalik Buterin for supporting the so-called “rescue hardforks” for recovering stolen crypto during hacker attacks. This was preceded by a Twitter-dispute between the largest community of bitcoin-traders Whalepool and Buterin.
The lesson Ethereum’s operators are teaching is implicitly this: When Vitalik’s funds are lost due to a contract executed to the letter with unwelcome results: Great choice. – Maxwell wrote on Reddit.
The founder of Ethereum also said that hardfork can be a good way out for blockchains at an early stage of development in emergency circumstances.
Some people believe that it is the possibility of a “rescue hardfork” that gives the Altcoins an advantage over Bitcoin. Maxwell strongly disagrees with this position.
When Vitalik’s funds are not lost, but an even larger dollar value is lost due to terrible foot-gun “address” design and Ethereum software misbehaviour: Bad choice.
The point they’re missing? No one should have that power. If there is even a choice to make the system has already failed. Paypal and Visa do reversibility better and didn’t require a pre-mine now worth billions of dollars.- stressed Maxwell.
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.

The South Korean currency exchange Bithumb opened registration for new users after the introduction of the “know–your–customer” (KYC) procedure.
At the end of December, the government of South Korea reported on a demand to prohibit the opening of anonymous unverified accounts for users of crypto exchanges. It resulted in the development of laws and regulations, according to which at present registration on the Korean stock exchanges everybody must pass through the KYC.
The developers of the Bithumb reported that from February 9, users are able to verify their profiles via an open account in Nonghyup Bank. Moreover, the report says that the last revisions on the integration of the verification through Shinhan Bank will soon be completed.
The South Korean crypto exchange Bithumb was able to introduce the KYC system within ten days after the official ban of anonymous trading accounts in the whole country.
According to media reports, on January 30, 2018, new legislation was introduced in the country, created by the Financial Services Commission (FSC). It obliges crypto exchanges to introduce the KYC procedure for all the platform users. Thus, for the implementation of trading on the Bithumb, new users, as well as previously registered ones, must pass the KYC necessarily.
