Can blockchain smart phones be used in the mainland
in terms of application scenarios, the white paper points out that 5g blockchain mobile phone has five application scenarios: digital identity authentication, financial application, supply chain traceability application, judicial application and express instry application
taking digital identity authentication as an example, blockchain technology provides a new technology route for decentralized digital identity, which can verify the identity of users through an ID. users do not need to remember traditional authentication marks such as user name and password. Any website can use ID as a way of user login, and can also be used as the identity provider of ID. it not only solves the problem, but also does not need to rely on the centralized website to confirm the digital identity
at the innovative scheme design level, China Telecom blockchain and digital economy Joint Laboratory proposes a blockchain mobile phone research scheme of "security platform, independent identity authentication, multi-level application" in combination with blockchain, 5g and other technologies, aiming at the key problems of "number change" fraud, telephone harassment, mobile phone loss, and unreliable information in traditional mobile phones
according to the public report, China Telecom also participated in the writing of the white paper on blockchain telecom instry application (version 1.0). In May of this year, the Third Plenary Session of the trusted blockchain promotion plan was held, and experts from China Mobile, China Telecom and China Unicom, the co leaders of the telecom application project team, on behalf of the project team, officially released the white paper on blockchain telecom instry application (version 1.0)
the white paper is the world's first white paper on the application of blockchain telecommunications instry, which was led by three major basic telecommunications enterprises and jointly written by more than 10 units, including Huawei, ZTE, fun chain technology and Huaqi communications.

HTC is developing an Android mobile phone driven by blockchain technology. The phone, codenamed exos, will provide a system level wallet function with built-in security hardware to support digital cryptocurrency and decentralized applications
at present, HTC's proct focus is virtual reality helmet vive. Phil Chen will be responsible for all blockchain and cryptocurrency related projects within HTC, including the exos phone
However, e to the lack of a real phone, it is not clear what kind of functions this kind of blockchain mobile phone can provide that are different from conventional mobile phones, so as to improve the transaction experience of digital cryptocurrencyit is said that the blockchain mobile phone will improve the security and user experience ring transaction by integrating the native wallet function in the mobile phone. It can also conct direct digital cryptocurrency transactions among users in the network composed of the mobile phone, eliminating the cost of mining
however, the above mentioned functions can be realized on ordinary smart phones by installing software. The transaction of bitcoin and other digital cryptocurrencies will generate mining costs, which can not be avoided on ordinary mobile phones or blockchain mobile phones. Web browsers and chat applications that provide privacy protection can also be implemented by installing applications
The great Magellanic nebula is about 180000 light-years away, the Magellanic nebula is 210000 light-years away, and the bright star on the lower left is the base of the ship α Old man star, a resident of the galaxy, is only 310 light-years away. Both big and small clouds are in the southern half of the sky, and the sphere is about 20 meters away from the southern pole ° Right and left. Located at the junction of the two constellations, Xiphophorus and Yamagata, the cloud spans the two constellations and occupies 8 °× seven ° The area of the sky is equivalent to the apparent area of more than 200 full moons. The wheat cloud is located in Rhododendron, occupying 4 °× two ° It's the area of 30 full moons. The distance between the barley cloud and the wheat cloud is about 20 meters ° In the southern hemisphere, the big and small wheat clouds hang high near the zenith of the southern sky all the year round. They never fall below the horizon. As we see in the northern hemisphere, the Big Dipper will never fall below the horizon. They are a pair of treasures of Nantian. Unfortunately, most of the northern hemisphere can't see them. In the Spratly Islands area of China, they are only found near the southern horizon.
the Magellanic nebula is a small and irregular galaxy. It is a satellite galaxy of the Milky way and orbits around the Milky way once every 1.5 billion years. Because it has no standard fixed shape, the Magellan Nebula has become the most controversial object in the southern hemisphere, even the most imaginative object. Some astronomers say that the Magellanic Nebula seems to interact with dark matter in the universe to form a galaxy bend
what is galactic curvature? I think this is more difficult to explain. To put it simply, the operation of nearby nebulae may have an impact on our galaxy, just like the agitation of the other end of the carpet, which can cause a wave like shape distortion. At present, the Galactic silver plate has become a bowl
apart from the rosy Keyhole Nebula and the shining Southern Cross, the most famous celestial bodies in the southern hemisphere belong to the large and Small Magellanic galaxies. The Milky way is not visible in the Chinese mainland. These two celestial bodies are the galaxy of the galaxy. Like M32, NGC205, next to the M31, is a small galaxy near the big galaxy. LMC is 160000 light-years away from the earth, and SMC is 190000 light-years away from the earth
when German Amateur Astronomer Tonghao came to Australia to observe stars, he mistook LMC and SMC for two "clouds" in the sky. How can the wind not blow away? It was a joke. Ngc104 next to SMC is another good object to watch, and the spider Nebula next to LMC should not be missed
like our Milky way, Magellanic Clouds also include gas and stars. Barley cloud belongs to the dwarf spiral galaxy or irregular galaxy, and its mass is 1 / 20 of that of the Milky way. Wheat cloud is an irregular galaxy or an irregular rod dwarf galaxy with only 1 / 100 of the mass of the Milky way. There are abundant gases in magellanic clouds; The mass of neutral hydrogen is 9% and 32% of their total mass respectively, which is much larger than that of the Milky way. This suggests that they are less evolved than the Milky way. Their interstellar st content is less than that in the Milky way, while the young group I has a large number of objects, with a large number of high luminosity O-B stars; In addition, new stars, supernova remnants and X-ray binaries have been observed. For example, a supernova (SN 1987A) in the Large Magellanic Cloud was discovered on February 23, 1987. Its maximum brightness is 250 million times that of the sun. It is considered to be the brightest supernova in 383 years. Magellanic Clouds orbit the Milky way once every 1.5 billion years. Every time it gets closer to the Milky way, its stars and gases will change under the gravity of the Milky way. The Magellanic Cloud has now been torn apart and its stars will become part of the Milky way. The big magellanic cloud will eventually be the same fate
the large and Small Magellanic nebulae are the closest neighbors to the Milky Way galaxy. For hundreds of years, these two nebulae have been considered as companion galaxies of the Milky way. But a new study by Harvard astrophysicist gurtina besla and his colleagues shows that the Magellanic Cloud is a recent arrival and the first visitor to the galaxy
the two nebulae are not only irregular in appearance, but also like volcanic clouds. The Large Magellanic nebula is 160000 light-years away from the earth, and its diameter is about 1 / 20 of that of the Milky way; The Magellanic nebula is 200000 light-years away from earth and is only a few hundredths the size of the Milky way
many years ago, astronauts claimed that the three-dimensional velocity field of the Magellanic Nebula passing through the Milky way is much larger than before. There are two explanations for this phenomenon: 1) the Milky way is much larger than before; 2) the Magellanic nebula is not constrained by the gravity field of the Milky way. But further research by besla and his colleagues confirms the second view, and they claim that the Magellanic Nebula passed through the Milky way for the first time
however, such observations are still questionable. Because if we take the Milky way as the reference plane, the warping depth can reach 10000 light-years up and down. But these two nebulae only arrived once a billion or three billion years ago, so their gravity tides are unlikely to cause such warping. Faced with such a situation, besla said: "we still have a lot of unsolved mysteries. When an answer appears, there may be more problems."
In the 10th century, when Arabs and Portuguese sailed to the south of the equator in the 15th century, they noticed these two cloud like objects in the southern sky, which were called "Cape of good hope clouds". Portuguese navigator Magellan first described them accurately when he sailed around the world in 1521, and later named them after him. The big cloud is called the big Magellanic nebula, or LMC for short; The small cloud is called wheat cloud (SMC); Collectively known as Magellanic Cloud. In 1912, American astronomer Leavitt discovered the relationship between the circumference of the Cepheid variable of the wheat cloud. Herzpolon and Shapley then determined the distance of the wheat cloud, becoming the first confirmed extragalactic galaxy. The distance of big wheat cloud is 160000 light years, and that of wheat cloud is 190000 light years. They are 50000 light years apart in space. Large and small clouds are among the most recent galaxies, which enables us to analyze their member celestial bodies carefully. Therefore, they are important astronomical observation objects and important sources of galactic astrophysical data
recently, triangle mobile phone, a necessary artifact for blockchain users, officially appeared on its official website. The mobile phone puts forward the innovative idea of using blockchain thinking as a mobile phone: each mobile phone is a node, and each node will own more than 51% of the rights and interests generated by the behavior data contributed by the network, That is to let every user become the creator and sharer of the brand.
there are many solutions to the security problems of digital currency. Using personal intelligent terminal devices is not the best solution with the lowest cost. I think it's HTC
as a POW, smart phones have no future. After all, POS costs less
HTC should also realize this internally, but as an attempt, it is not bad for HTC to lower the shipment volume.
In May, HTC announced for the first time that it was developing a blockchain smartphone called exos. This news was announced after it had a bad start this year, which is a quite eye-catching project. HTC shipped more than 2 million units in the first quarter of last year. According to IDC, a market research firm, the company shipped only 630000 units in the first quarter of this year
considering the financial situation of HTC, the launch of exos mobile phone is very important. Currently, the verge has learned from HTC's Phil Chen about the launch date and estimated price of the mobile phone. Although he was vague about the details, he revealed that the phone is expected to be launched by the end of this year and the price will be announced by the end of the third quarter. When the verge mentioned that Finney, the world's first blockchain mobile phone (developed by sirin labs), was selling for $1000, Phil Chen said the exos price was "similar."
According to foreign media reports, HTC is the latest company to join the blockchain entrepreneurship boom. HTC announced plans to proce a new Android smartphone with blockchain technology. The company named the phone "exos" and equipped it with a universal digital wallet and security hardware to support cryptocurrency and distributed applications
HTC virtual reality head show project, Chen Xinsheng, founder of HTC vive, will be responsible for all the blockchain projects of the company. At the consensus 2018 global blockchain conference held in New York today, Chen Xinsheng said: "we envisage building a mobile phone on which you have your own electronic key, your own identity and data, and your mobile phone is the center."
HTC's exos mobile phone may be the second blockchain smart phone in the world. The first blockchain smartphone, named Finney, was launched by sirinlabs, an Israeli technology company. It allows people to store and use digital currency without paying transaction fees. The phone costs $1000
