First of all, as an ordinary person, you'd better not understand this kind of market. Professionals may not play well
in the past two days, I saw an article saying that all cryptocurrencies have false transaction volume, revealing the shocking deception in the circle of blockchain. Of course, as an ordinary person, I am very curious. Isn't it amazing that blockchain cryptocurrencies are spread on the Internet? Why does the trading volume of this kind of currency still have fraud? Isn't it just like Taobao merchants doing activities to swipe orders? Or is the price of the special offer unreasonably high
to get bitcoin, first of all, your computer should have the latest version of bitcoin client installed. After opening the client, it will automatically download all the transaction information data on the network to the local. Depending on the network speed, this process may take several hours. At this time, your account balance is 0, you can ask your friends to send you some coins, but there are two more feasible ways: one is to do miner mining, the other is to do merchant acquisition
nowadays, bitcoin mining is not as profitable as it used to be, but it is still profitable. Joining the mine pool is a good way to earn bitcoin. On the one hand, this method does not require very high computer performance, and does not require so high electricity costs. Here is a list of ore pools (for reference only). Joining the mine doesn't mean you can take bitcoin. Because mining is becoming more and more difficult, but if you are interested in mining, you can click here to see how to mine bitcoin
2. On the last day of the 19th century, famous European scientists gathered together. At the meeting, W? Thomson (Baron Kelvin) made a new year's speech. Looking back on the great achievements of physics, he said that the physics building has been completed, and only some decoration work remains. At the same time, while looking forward to the future of physics in the 20th century, he said thoughtfully: "the dynamic theory affirms that heat and light are two ways of motion. Now, its beautiful and clear sky is covered by two dark clouds." the first dark cloud appears in the wave theory of light, ”"The second dark cloud appears in the Maxwell Boltzmann theory of equipartition of energy." W. In April 1900, Thomson published an article entitled "dark clouds over the dynamic theory of heat and light in the 19th century". The first dark cloud he said mainly refers to the contradiction between the results of Michelson Morey experiment and the theory of ether drift; What he said about the second dark cloud mainly refers to the results of the theoretical interpretation of the specific heat of gas and the potential radiation spectrum by the energy equipartition rule in thermodynamics, which are different from the experimental results, especially the "ultraviolet disaster" in the blackbody radiation theory. Kelvin is an outstanding theoretical physics and experimental physicist in 19th century England. He is an influential authority in physics. His statement tells the basic situation of physics development to the end of 19th century and reflects the main trend of thought in the field of physics at that time
physics developed to the end of the 19th century, which can be said to be quite perfect and mature. All physical phenomena seem to be able to get satisfactory answers from the corresponding theories. For example, all mechanical phenomena can be explained from classical mechanics in principle. Newtonian mechanics and analytical mechanics have become effective tools to solve mechanical problems. For the analysis of electromagnetic phenomena, Maxwell's electromagnetic field theory has been formed, which is the unified theory of electromagnetic field. This theory can also be used to explain the basic problems of wave optics. As for the thermal phenomenon, there are phenomenological thermodynamics and statistical mechanics theories, which can make a reasonable explanation for the macroscopic law of the thermal motion of matter and the microscopic statistical law of the thermal motion of molecules. In a word, the classical physics building with classical mechanics, classical electromagnetic theory and classical statistical mechanics as the three pillars has been built, and the foundation is solid and magnificent! Under such circumstances, it is no wonder that physicists will feel intoxicated and feel that physics has achieved great success, thus asserting that they will not be able to do anything in the future. At that time, this kind of thought not only existed universally in physics, but also had a long history
Planck made a speech in 1924. In his speech, he recalled that when he was studying physics at the University of Munich in 1875, his physics teacher P. Jolie (1809-1884) advised him not to study pure theory, because physics "is a highly developed and almost perfect science". Now this science "seems very close to taking the most stable form.". Perhaps, there is a st or a small bubble in a corner, which can be studied and classified. However, as a complete system, it is established firmly enough. And theoretical physics is clearly approaching the level of perfection that geometry has had for hundreds of years. " Another famous teacher of Planck, G? Kirchhoff (1824-1887) also said a similar thing, he said that "physics has done nothing but add a few numbers after the decimal point of the known law." Although Kelvin's evaluation of the achievements of physics is too extreme, he can find "two dark clouds" in the clear sky and is worried about them, which shows that he is far sighted. The history of the development of physics shows that it is these two small dark clouds that finally led to a big storm
the first dark cloud -- Michelson Morey experiment and the collapse of "Ether" theory. Sunlight passes through a vacuum to the earth, and light from galaxies billions of light-years away also passes through space to the earth. Why can light wave propagate in vacuum? What is its medium of transmission? Physicists have found a medium for light transmission - "Ether"
Aristotle, the ancient Greek philosopher, first proposed "Ether". Aristotle thought that the lower boundary was composed of fire, water, earth and air; Add the fifth element to the upper bound, "Ether". After Newton discovered the universal gravitation, he met a difficult problem: in the vacuum of the universe, what medium does gravitation propagate? In order to find a complete solution, Newton revived Aristotle's "Ether" theory, and believed that "Ether" was the propagation medium of gravity in the cosmic vacuum. Later, physicists developed the theory of "Ether", believing that "Ether" is also the medium of light wave propagation. Light, like gravity, is transmitted by the ether. They also assume that the whole universe is full of "Ether", which is a thin, imperceptible medium composed of very small elastic spheres. In the 19th century, Maxwell's electromagnetic theory also described the medium that transmits light and electromagnetic waves as a kind of "Ether" that has no weight and can absolutely penetrate“ "Ether" not only has the nature of electromagnetism, but also is the transmitter of electromagnetic effect, and also has the nature of mechanical mechanics. It is an absolutely static reference frame, and all movements are relative to it. In this way, the electromagnetic theory is consistent with Newtonian mechanics“ The concept that "Ether" is the common carrier of light, electricity and magnetism is generally accepted by people, forming a "etherology"
however, after confirming the existence of "Ether", a new problem arises: if the earth moves around the sun at the speed of 30 kilometers per second, it must encounter the wind of 30 kilometers per second. At the same time, it must also have an impact on the propagation of light. The emergence of this problem causes people to explore whether "yitaifeng" exists or not< In 1887, Michelson (1852-1931) cooperated with American chemist and physicist Murray (1838-1923) to carry out a famous experiment in Cleveland: "Michelson Murray experiment", namely "ether drift experiment". The experimental results show that no matter the direction of the earth's motion is the same as or opposite to the direction of light, the measured speed of light is the same, and there is no relative motion between the earth and the "Ether". Therefore, there is no "Ether" or "absolutely static space". Because this experiment is easy to understand in theory and accurate and reliable in method, there is no doubt that the experimental result denies the existence of "Ether"
the Michelson Morey experiment puts scientists in a dilemma. They may have to abandon the etheric theory that has explained many phenomena of electromagnetism and light. If they dare not give up ether, then they must give up Copernican's theory of earth movement, which is older than etherology. Classical physics is at a loss in the face of this famous experiment
the second dark cloud -- blackbody radiation and "ultraviolet disaster"
at the same temperature, the brightness and color (wavelength) of different objects are different. Dark objects have strong ability to absorb radiation. For example, the absorption rate of coal to electromagnetic wave can reach about 80%. The so-called "blackbody" refers to the ideal object that can absorb all external radiation without any reflection and transmission, and the absorptivity is 100%. There is no real blackbody, but a cavity with a small hole on its surface can be regarded as an approximate blackbody. Because the radiation entering the cavity through the small hole will not leak out from the small hole after many times of reflection and absorption in the cavity
at the end of the 19th century, lummer (1860-1925) and others' famous experiment blackbody radiation experiment found that the energy of blackbody radiation is not continuous, and its distribution according to wavelength is only related to the temperature of blackbody. From the perspective of classical physics, the results of this experiment are incredible
how to explain the results of blackbody radiation experiment? At that time, people started from classical physics to find the laws of experiments. Incorrect premise and starting point lead to failure in the end. For example, Wien, a German physicist, established a formula for the distribution of blackbody radiation energy according to wavelength, but this formula is only consistent with the experimental facts when the wavelength is relatively short and the temperature is relatively low. British physicist Rayleigh and physicist, astronomer King think that energy is a continuous change of physical quantity, establish the blackbody radiation formula which is more consistent with the experimental facts when the wavelength is longer and the temperature is higher. However, according to the Rayleigh gins formula, in the short wavelength region (ultraviolet region), the radiation intensity can increase endlessly with the shortening of the wavelength, which is far from the experimental data. So this failure was called "ultraviolet disaster" by Ellen fester. Its failure undoubtedly indicates the failure of classical physics theory in the problem of blackbody radiation, so it is also the "disaster" of the whole classical physics.

3. Bitcoin was first popular with some programmers. When they exchanged data with them, they exchanged bitcoin.
4. "Blockchain is an important concept of bitcoin. Following the explosion of artificial intelligence and bitcoin, blockchain technology is also on fire! Even in the next 2018, there will be signs of high fever. Why is it so hot all of a sudden? Although blockchain has defects, its advantages are more obvious. A lot of capital will flow into the blockchain, because compared with other concepts, the concept of blockchain is easier to hype "
blockchain is a technology implementation of distributed storage based on cryptography, and its significance is to ensure the security and reliability of information circulation process, but blockchain is not absolutely perfect, it depends on many factors
the benefits of blockchain. It has to be said that as a supplement to the social credit system, blockchain has natural advantages
1. Smart contract, which is the foundation of blockchain platform. With the help of smart contracts, rules can be applied safely when dealing with transactions. They can be used to automatically perform verification steps to encode conditions previously contained in signed physical contracts
2. Distributed storage, distributed storage system, is to store data in multiple independent devices. Traditional network storage system uses centralized storage server to store all data. Storage server becomes the bottleneck of system performance and the focus of reliability and security, which can not meet the needs of large-scale storage applications
3. The pursuit of capital and the pursuit of profit by capital are just like Satan's hell fire burning all the evil sources. The greed of capital will surely threaten all the hype concepts and reap the green of leeks. Good capital injection can also bring back the rapid development of the instry
"blockchain is the most popular fintech (Financial Technology). This innovative technology from bitcoin is subverting the financial instry and our lives. In 2015, blockchain became the highest financing sector in US venture capital, breaking through US $1 billion. This kind of hot financing scene only appears in foreign countries“ Few people in China really understand blockchain technology, "said a senior practitioner. This is the reality. In China, most of the companies that are known as blockchain technology are unwilling to give up the dividend of bitcoin and still stay in the primary stage of currency speculation; The transformation of the financial sector, more in essence, is just speculation concept stocks; There are few people who sincerely do technology. "
"blockchain is the underlying technology of bitcoin, which solves the process of bitcoin from 0 to 1. At this stage, blockchain has become a high-frequency word in the big and small science and technology summit, and its popularity is no less than that of "o2o" in the previous two years. When people are discussing blockchain, they are more concerned about how to use blockchain, and they have no doubt about the application value of blockchain. " Blockchain is a decentralized trust mechanism. In the past, blockchain was mainly used in bitcoin. Until the last half year, blockchain has graally started to have some other applications, especially in the financial field
blockchain is a technical solution to maintain a reliable database collectively through centralization and distrust. Generally speaking, blockchain technology refers to a way for the whole people to participate in bookkeeping. There is a database behind all the systems. You can think of the database as a big ledger. So it's very important who keeps this account book. At present, whose system will keep accounts, wechat's account book is Tencent's account book, and Taobao's account book is Ali's account book. But now in the blockchain system, everyone in the system can have the opportunity to participate in bookkeeping. If there is any data change in a certain period of time, everyone in the system can conct bookkeeping. The system will judge the person who has the fastest and best bookkeeping in this period, write the content of his records into the account book, and send the content of the account book to all other people in the system for backup. In this way, everyone in the system has a complete account book. This way, we call it blockchain technology
bitcoin is one of the most successful applications of blockchain technology. Specifically, the blockchain is a series of data blocks generated by the use of cryptography Association, and each data block contains the information of effective confirmation of multiple bitcoin network transactions. The structure of blockchain storage data is a chain composed of "storage blocks" on the network. Each block contains all the information exchange data in the network within a certain period of time. Blockchain is the underlying technology of bitcoin, but its role is not limited to bitcoin. Through cluster or cloud mode operation, the nodes can expand horizontally, and continuously improve the overall network performance based on benign competition
bitcoin has no legal compensation and compulsion, and its circulation range is limited and unstable. Bitcoin also has strong substitutability, so it is difficult to be a general equivalent. No matter how skillful the blockchain technology is, it is impossible to proce a national currency, and the mass investors should not follow suit.

5.
The concept of bitcoin was first proposed by Nakamoto on November 1, 2008, and was officially born on January 3, 2009. According to the idea of Nakamoto, the open source software is designed and released, and the P2P network on it is constructed. Bitcoin is a virtual encrypted digital currency in the form of P2P. Point to point transmission means a decentralized payment system
the design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. The biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity
6. My friends were cheated by 740000 together, which has saved today,
7. First of all, bitcoin should have a professional miner. First of all, the home's ordinary computer mining should be configured. Even if the configuration is enough, you can't even pay the electricity bill for a day and a night's mining. Under the operation of the professional miner, it will take about a year to earn back the miner's money. So what's wrong with time deposit? Even if the fixed deposit is not good, the income of Monetary Fund and other procts is still good. Now there are too many network cable publicity. There are only two ways to make money. The first way is to make money, which will not be disclosed. So the way you don't know will always make money. The second way is to make money in laws and regulations. For the general public, it is steady to work, save and manage money.
8. Electric vehicle manufacturer Tesla and SpaceX CEO Elon middot; Elon Musk has joined many cryptocurrency supporters. He just modified his profile on twitter, leaving only & lt; Bitcoin & quot; One word. Some data show that after musk changed his twitter profile, bitcoin rose 15% in less than 30 minutes and its price was more than $37000 per coin
Musk's move makes bitcoin hot search again, and makes us ordinary people pay attention to it again
although bitcoin is popular today, we should carefully look at the truth and identify the right time before making a decision
9. The existing virtual currency is actually bitcoin, which gives people the opportunity to transfer money out of China and trade with international businesses and customers. For some students studying abroad, it's convenient to use bitcoin. It's very convenient to transfer bitcoin to or from abroad. Compared with the cumbersome examination and approval of banks, they prefer to use bitcoin platform, such as haobtc, okcoin and BTCC, which are relatively large bitcoin platforms in China. The above transactions are very convenient.
