Understanding and views on virtual currency and blockchain

1. digital currency has a wide range of transactions, virtual currency is small, knowledge is limited, language expression ability is general, but we have tried our best to answer, hope the answer can help you!

2. blockchain technology uses mathematical methods to achieve distributed accounting and solve the trust problem, so as to complete the decentralization, which will bring far-reaching influence in many fields such as communication, finance, Internet of things, government management and so on
blockchain refers to the technical solution of collective maintenance of a reliable database through centralization and distrust in the past, and it is a technical way for the whole people to participate in bookkeeping. Previous bookkeeping methods were all centralized and needed centralized intermediary, whether it was traditional government, financial institutions, notarization institutions or emerging e-commerce platform and online payment platform
in economic hypothesis, information is sufficient. In fact, it is precisely because of insufficient information that there are very large intermediaries. The existence of intermediaries increases the transaction cost and raises the transaction threshold. In essence, blockchain technology is a large-scale collaboration tool. It makes direct value transfer possible by using pure technology for the first time, and continues the trend of Internet decentralization and disintermediation. Disintermediated blockchain technology will greatly subvert the information intermediary instry
blockchain technology is the basic technology for building bitcoin data structure and encrypted transmission of transaction information, which realizes the issue and transaction of bitcoin. The core of blockchain technology is that all the current participating nodes jointly maintain the transaction and database, so that the transaction is based on the principle of cryptography rather than trust, so that any agreed parties can directly carry out payment transactions without the participation of a third party
technically, a block is a data structure for recording transactions, reflecting the capital flow of a transaction. In the system, the transaction blocks are connected to form a main chain, and all the nodes participating in the calculation record the main chain or part of the main chain
a block contains the following three parts: transaction information, hash formed by the previous block and random number. Transaction information is the task data carried by the block, including the private keys of both parties, the number of transactions, the digital signature of electronic currency, etc; The hash hash formed by the previous block is used to connect the blocks and realize the sequence of past transactions; Random number is the core of the transaction. All nodes compete to calculate the answer of the random number. The node that gets the answer the fastest generates a new block and broadcasts it to all nodes for updating, so as to complete a transaction.

3. Here's bitcoin
bitcoin price has been cut by the waist
how to implement blockchain application is still the main problem. In addition to bitcoin, the large-scale application of blockchain in other scenarios has not yet reached the commercial stage. Looking back to the second half of 2017, the price of bitcoin almost reached a new high every day, and finally reached the peak in the South Korean exchange with the highest premium in the world - about 140000 yuan per piece. On June 3, 2018, as of press time, coinbase bitcoin trading platform quoted 49688 yuan, and the price of bitcoin has been cut. Since the beginning of this year, the price of bitcoin has rarely seen eye popping ups and downs, and the overall trend of monthly decline
bitcoin development status
according to the data of the in-depth analysis report on business model innovation and investment opportunities of the blockchain instry released by the foresight Instry Research Institute, bitcoin prices showed a downward trend in May, with the overall market value falling from US $157.3 billion at the beginning of the month to US $127.4 billion at the end of the month, a decrease of 19%; In addition, there are 444000 active addresses and 197000 transfers per day. From the trend point of view, the number of active addresses and daily transfers are positively correlated with the transaction price. In May, the overall trend is volatile, and the downward trend is very obvious
reasons for the steady decline of bitcoin in the past half year
how to understand the "steady decline" of bitcoin in the past half year? There are two main reasons: firstly, the most important reason is that institutional investors and speculators who have accumulated a large number of "profit" are cashing in their profits and leaving the market; Secondly, before the blockchain instry has no real application and profit model, the rise of bitcoin price can only be regarded as speculative speculation. In addition, it is an undeniable fact that the Central Bank of China has made a decisive move to close the bitcoin trading platform, which has achieved remarkable results in preventing bitcoin speculation
at present, the domestic bitcoin exchanges have basically moved to foreign countries, which has nothing to do with China. Investors operate on those platforms at their own risk
the current market is not very good. Only when the market is good, can investors find ways to participate in bitcoin investment. As the total market value of the coin circle is still small, with more blockchain applications, there is still potential in the future
over consumed blockchain
e to the "tepid" price of bitcoin, blockchain, as its underlying technology, has reached the level of "known to all women and children", and even surpassed bitcoin in recent years
recently, a series of related reports are suspected of making up for the number and full of hype, and blockchain has obviously been over consumed. In addition to bitcoin, the large-scale application of blockchain in other scenarios has not yet reached the commercial stage
with the graal deepening of the understanding of blockchain technology, domestic enterprises have laid out blockchain technology, platforms and applications, including Internet enterprises such as network, Tencent, Ali, Jingdong, Netease, major banks, financial enterprises such as Ping An of China and Huawei. In terms of application, China actively explores and promotes blockchain + applications in the form of alliance chain and private chain to help solve the pain points of related instries, improve efficiency and rece costs.

4. Bitcoin is an electronic payment currency. You can understand it as RMB on the Internet. Blockchain technology is the technology to develop this kind of currency. Generally speaking, bitcoin was invented with blockchain technology. At present, blockchain can be applied to the Internet of things, intelligent manufacturing, supply chain management, digital assets and other fields. It is useful to use this technology. Here we can recommend a Domenech jewelry's Maobei digital virtual currency, which is a good practical application scenario with the combination of physical jewelry and blockchain technology. Please adopt it

5. Virtual currency is a kind of blockchain technology. Some countries are legal, such as Japan, Russia, South Korea, etc. 66otc is currently the most fluent, reliable and best used OTC platform

6. Views on virtual currency
from q-coin and counting roll used to buy props to bitcoin which can be exchanged with us dollar and euro today. It shows that the utilization rate and universality of virtual currency are graally increasing. I think this kind of virtual currency has both advantages and disadvantages. Virtual currency makes up for the deficiency of currency, but it will not replace the real currency
1. Security of virtual currency. The day before yesterday, a bitcoin trading platform headquartered in Japan was favored by many people. However, e to the loss of 750000 bitcoins from customers and 100000 bitcoins of its own, the company had to file for bankruptcy protection. This fully shows that the security of virtual currency is difficult to guarantee
2. The use of money cannot be regulated. The problem is that there is no manager similar to the central bank. Due to the strong anonymity, it is easy to be used for illegal transactions such as speculation and drugs, as well as money laundering. Without the network of financial institutions, it is difficult to grasp their liquidity, which will bring difficulties to taxation
although it has many uncertainties, virtual currency is very effective and reliable to a certain extent
1. The possibility of inflation of virtual currency is small, and it is not affected by policy. Avoiding the influence of the central government on finance, virtual currency can prove the stability of its value because of its limited circulation. It will not raise prices and lower the value of money because of the increase of money supply
2. Strong circulation. People can use bitcoin to trade anywhere in the world where there are networks and computers, which is very convenient
it not only saves time, but also saves a lot of transaction costs
after comparison, I think that the virtual currency will be saturated and will not pose a threat to the real currency. On the one hand, in the backward regions and countries, they rely more on currency, resulting in a gap with the developed regions. On the other hand, with the development of network technology, the security of virtual currency will be more and more difficult to determine. It is also very difficult for people to use a lot of money in the form of virtual currency in huge investment. Especially in a country with traditional culture such as China, people are more confident that they will hand over their property to the financial instry such as banks, rather than in the online world like flowers in the mirror< There is no comparability between bitcoin and stock. Stock is people's profit expectation for a company. For example, a company constantly proces new procts to increase its wealth. People can obtain wealth growth with the company by holding shares of the company. And the stock is an investment proct, without monetary attribute, it is impossible to say how much ICBC stock an iPad is worth. On the contrary, like bitcoin, the stock can be converted into legal currency through the exchange to purchase the iPad. Similarly, in the so-called companies that accept bitcoin payment, all of them are marked with legal currency. They accept bitcoin through a third-party company, and finally receive legal currency from a third-party company
therefore, stock is people's expectation for the future development of a company, and it is an investment proct. There is no comparison with bitcoin, which clamors to become a currency
2. The existence of money lies in circulation and pricing. A thing that has been reced to a speculative tool since its existence, expecting appreciation and redistributing wealth can not become money
3. As cndx God said, bitcoin will have 2.0 in the future, which will be seamlessly connected with 1.0. That's funny. Why should the inventor of 2.0 connect with 1.0? Just as bitcoin does not connect with RMB, it is another opportunity for wealth redistribution
4. The existence of virtual currency can only meet the money laundering needs of a small number of people, so there is a market. For example, if someone wants to launder US $1 million recently, the ratio of bitcoin to legal currency will change, which is also in line with the market rules. Of course, money laundering is risky. If you buy one million dollars of bitcoin, you will hold it forever without losing any money
5. My legal currency is in the bank. If I lose it, I can still get it back with my ID card. Is my bitcoin password gone? Who should I go to
6. The currency expected by cndx will not be lost. At most, it will play in a certain circle just like Q currency
7. This thing is the proct of anarchism. If you want to embody value, you can only do it without government. The distribution of wealth depends on power and blood. For example, if you hold 10000 bitcoins, ZF says not to use them, and you say I'll use them. Bang, you're dead. Oh, bitcoin has appreciated again, because the total amount is less than 10000.

7. Regular blockchain enterprises are not money, and blockchain traces the source to crack down on fake and inferior information
in the past two years, the word blockchain is very popular, and blockchain e-commerce will undoubtedly be the biggest wind outlet in the next decade. However, the instry is in chaos. Many people think that blockchain is money and have many misunderstandings about blockchain. So before we talk about blockchain, we should first talk about the idea of blockchain
blockchain is now understood by most people as "currency". There are too many coin cards in the coin circle, bitcoin and bitcoin. In fact, blockchain has nothing to do with currency. It is a technology, a business ecology and an idea. It is mainly applied in every field. It is extremely similar to the Internet. Talking about blockchain now is like the Internet 20 years ago. What did we talk about the Internet 20 years ago? When talking about its technical architecture, operating system, language, server and so on, it was said at that time that Internet e-commerce was deceptive, because many people had not been exposed to this aspect. In fact, many people have misunderstood blockchain, especially after being confused by the currency circle
When did jiuzero blockchain start? Jiuling started to investigate and prepare from 2016, and has about half a year to investigate all aspects of the blockchain. In 2017, it began to enter the field of blockchain. By 2020, it will be the fifth year. It has gained a lot of experience and achieved a lot in application. We've never played with coins, never engaged in ICO. In the first few years, we didn't make a lot of noise, that is, we should do a good job in technology, platform and browser, and apply them in traceability. We have done a good job in the application of traceability since 2017, and many procts have been launched; In 2018, more than 10000 procts will be applied in traceability. In 2019, it will be further promoted. This year, it will be further developed, and all procts will be opened up in the whole process of visualization. So at the beginning, we used it in the field of traceability. Since 2018, we have used it in the whole blockchain ecology, including blockchain traceability, blockchain invoice, sharing economy, supply chain finance, general points and other applications, as well as the platform technology services we built. We have entered this field in an all-round way, And relatively speaking, it is relatively mature and completely implemented
What's more, why is blockchain on fire now? Why does the development of blockchain reach the height of "thinking"? This is in line with the trend of the times
let's review the history of China's economic development in recent decades. The wealth of Chiang Kai Shek's time was concentrated on the local tyrants, evil gentry and warlords. Mao Zedong liberated most of the common people as peasants, and United most of them was more suitable for the situation of China at that time. Therefore, he defeated Chiang Kai Shek, overthrew the bureaucracy of the local tyrants, evil gentry and warlords, redistributed their wealth, developed the proctive forces again, and completely redistributed their revolution and distribution, Mao Zedong really realized serving the people and let the people live a good life. In the era of large collectives, people go to work in the countryside to earn points. According to the points you earn, how much food can you get. In Deng Xiaoping's time, I felt that this was not right. It might be that the efficiency was not high, and I ate a big pot of rice. Later, I started the reform and opening up. After the reform and opening up, the fields were divided into households according to the number of people. After that, the output increased a lot, which stimulated everyone's enthusiasm, increased the output and improved the efficiency. After the reform and opening up, commercial instrial enterprises began to develop
we can see that economic development is based on the needs of the times. China's reform and opening up has gone for decades, from the traditional economic era to the E-commerce Internet economy, and now the blockchain has come out, also because of the new problems of wealth distribution in the Internet era
in the Internet era, social wealth is highly concentrated on several platforms, such as Alibaba, Tencent, Internet, Jingdong, etc. the Internet e-commerce leaders have too strong a say in finance, resources, procts and other aspects. Social development has completely lost its balance. The uneven distribution of wealth has made the rich richer and the poor poorer. The instrial enterprises without money, including the whole of China, are now difficult to survive except for the monopolized central enterprises. At this time, there needs to be another revolution in business. The proctive forces must be redistributed and readjusted. It happens that blockchain is born to meet the needs of the era of transportation
the rules and mechanisms of blockchain are completely open and fair, can not be tampered with, and can not be decentralized. The oligarchs of institutions are removed to form a sharing economy for common development. Why does the government support blockchain so much? Because the government can fully enter the field of blockchain for supervision, and the privacy of citizens can be protected. Personal information in the Internet is not protected, and personal information in the blockchain is in their own hands. In the era of Internet e-commerce, oligarchs monopolize information resources. There are too many fake and shoddy procts and too many false information, so we have no way to distinguish them
at this time, the rule mechanism of decentralized supervision of blockchain emerges as the times require. Blockchain is not only a technology (it has made some improvement and promotion in the original Internet technology), but more importantly, it can solve the problems that cannot be solved by the Internet, traditional e-commerce and traditional ecology, such as traceability. Traceability in the Internet age can be falsified. A traceability source can be pasted anywhere, but the traceability of blockchain is different. The technology of blockchain is real. Everyone can participate together. Through distributed storage, everyone can get the data, and then all things can be traced, including procts and invoices, Including a person to send a message can be traced, stored, fidelity
the traceability of blockchain starts with raw materials, then proction and processing, then warehousing, sales, etc. every link should be visualized, with pictures, videos and words, which will leave traces of every link. Only in this way can we make everyone trust completely and be fair, open and transparent when there are too many fake and shoddy procts and lack of trust. In short, blockchain is to solve the problem that the Internet can not solve
when it comes to blockchain, bitcoin is the first thing that many people think of. In fact, bitcoin's contribution to the world is to put forward a rule and mechanism. Bitcoin itself has no value. It has no proct and no support. But its technology and concept are very good, because this technology can't be fake. The source code of this technology is open source and can be shared. Its technology uses the idea of blockchain
as soon as the rules and mechanisms of blockchain come out, they are sought after by everyone. However, in recent years, they have been confused by money. That kind of money is deceptive and runs counter to blockchain. On the contrary, it makes people distrust blockchain because they don't know enough about blockchain and think blockchain is money. Because if you want to understand a field, just like jiuzero blockchain has entered its fifth year, you are engaged in blockchain ecology, blockchain traceability, blockchain digital integration, blockchain technology development, blockchain browser development and so on every day. In this field, you are still learning constantly, because it is not easy to learn a field thoroughly. The reason why we have been very motivated in the past few years is because we know that it is a big trend and coming. Just like the Internet 20 years ago, many people don't believe, understand and turn a deaf ear to it. But ten years ago, Tencent, Alibaba, Huawei and other big enterprises got up. At the same time, now this opportunity is in front of us. Can we seize it? This is a question worth thinking about
finally, let's make it clear that blockchain has nothing to do with currency
for regular blockchain enterprises, the government has requirements and certification standards
standards: three basic requirements (patent, soft work, registered company in national blockchain Park, paid in registered capital, dedicated blockchain R & D funds), four landing application standards (blockchain browser, website, blockchain application scenarios, blockchain procts), five kinds of blockchain professionals (blockchain finance professionals, Blockchain digital professionals, blockchain credit management professionals, blockchain software development professionals, blockchain encryption technology professionals, and employees with bachelor degree or above who have been employed for more than one year) can get six basic subsidies
in the blockchain instry, there are at least tens of thousands of companies doing money and ICU. They all say that they are regular, but can they take out these certificates. The document points out that as long as the company has digital currency or ICO, it is not a blockchain company
under the background of this era, the ideas, rules and mechanisms, decentralized supervision and privacy distribution of blockchain can protect everyone's interests, redistribute proctivity assets, prevent the interests from being too concentrated on certain oligarchs and institutions, let everyone participate together, and let everyone exert their energy together to fight against counterfeiting, tax evasion, tax evasion, tax evasion, etc The real purpose of blockchain is to crack down on false transactions and create a conscientious ecosystem that can protect the interests of the people and provide hematopoietic function.

8. Blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. Blockchain is an important concept of bitcoin. It is essentially a decentralized database. There are more and more applications of blockchain, but the main application is bitcoin. After all, it can make money by investment. If you are interested, you might as well open an account number at the okex bitcoin exchange.

9.

Often when we talk about value, we will naturally relate to price. Indeed, price is an important data to measure value. As a blockchain technology, bitcoin's price reached 140000 RMB when it was high, and now it has dropped by about 50%, but it is still as high as 80000 RMB

At this point, you may have understood: if people do not have a common understanding of a thing, and do not give value to a thing, many things will not become "valuable". Just like our understanding of air and food, it is necessary for us to live and survive! This is the "consensus". We all believe that if we want to live, these two are indispensable! Therefore, we can conclude that the essence of value is consensus. What is the value consensus of virtual currency? Most people think that the essence of currency is not consensus, but the credibility and authority of the ruling government. This is not unreasonable. The government can only be one of the sources of value consensus, so most people think it is not comprehensive. In today's society, our consensus on the value of things comes from many ways, such as: Endorsement of authoritative institutions, corporate credit, religious belief, support of scientific theory
