How much money does blockchain have
Publish: 2021-05-06 12:29:51
1. blockchain is not a commodity. It can't be measured with money and can't be bought. And it's not money, it's just the underlying technology of cryptocurrency, technology, important things to say three times. Blockchain technology can be used in many instries to improve work efficiency. To understand the application of blockchain, you can see it in mimacaijing.
2. Blockchain mainly solves the trust and security problems of transactions, so it proposes four technological innovations to solve this problem:
(1) distributed ledger, that is, transaction bookkeeping is completed by multiple nodes distributed in different places, and each node records complete accounts, so they can participate in monitoring the legitimacy of transactions, At the same time, they can testify together
different from traditional distributed storage, the uniqueness of distributed storage of blockchain is mainly reflected in two aspects: one is that each node of blockchain stores complete data according to block chain structure, while traditional distributed storage generally stores data in multiple copies according to certain rules. Second, the storage of each node in the blockchain is independent and has the same status, which relies on the consensus mechanism to ensure the consistency of storage, while the traditional distributed storage generally synchronizes data from the central node to other backup nodes[ 8]
no single node can record the account data separately, so as to avoid the possibility that a single bookkeeper is controlled or bribed to record false accounts. In theory, unless all the nodes are destroyed, the accounts will not be lost, so as to ensure the security of the account data
(2) asymmetric encryption and authorization technology, the transaction information stored on the blockchain is public, but the account identity information is highly encrypted, which can only be accessed under the authorization of the data owner, thus ensuring the data security and personal privacy
(3) consensus mechanism is how to reach a consensus among all accounting nodes to determine the validity of a record, which is not only a means of identification, but also a means of preventing tampering. Blockchain proposes four different consensus mechanisms, which are suitable for different application scenarios and achieve a balance between efficiency and security
the consensus mechanism of blockchain has the characteristics of "the minority is subordinate to the majority" and "everyone is equal", in which "the minority is subordinate to the majority" does not completely refer to the number of nodes, but also can be the computing power, the number of shares or other characteristics that can be compared by computers“ "Everyone is equal" means that when the nodes meet the conditions, all nodes have the right to put forward the consensus results first, and then directly recognized by other nodes, and finally may become the final consensus results. Taking bitcoin as an example, the workload proof is adopted. Only when more than 51% of the accounting nodes in the whole network are controlled can a nonexistent record be forged. When there are enough nodes in the blockchain, this is basically impossible, thus eliminating the possibility of fraud.
(4) smart contract, which is based on these trusted and tamperable data, can automatically execute some pre-defined rules and terms. Take insurance as an example. If everyone's information (including medical information and risk occurrence information) is true and reliable, it is easy to carry out automatic claim settlement in some standardized insurance procts

3. 1. Bitcoin
it is the birthplace of blockchain technology, and the market has confidence in it. It still maintains a stable growth under the adverse situation of major policies. Once it solves the problem of capacity expansion, the price rise can be predicted
2. Ethereum
compared with bitcoin, the advantage of Ethereum is that it has no policy problems. Although the event led to its bifurcation, the establishment of enterprise version Ethereum alliance may solve this problem. Its concept and Prospect of smart contract attract many developers to follow
the essence of community operation is that the majority decides the minority when indivials support eth
3. Zec
compared with bitcoin and Ethereum, the risk of z-coin will be greater, and its value will take a longer time to reflect. But in the long run, the value of anonymity will be one of the values that human beings generally pursue
4. BTS
bitstocks are very powerful and the system is very stable. Decentralized trading, anchoring system and so on. Although the founder bm's brain damage has hurt the community, the value of bitstocks is obviously undervalued. It is a wise choice to hold bitstocks on the cheap.

4. Blockchain digital currency refers to cryptocurrency. The underlying technology is blockchain. There are many cryptocurrencies. Bitcoin is more famous. Detailed digital currency can be found in cryptofinance mimacaijing.
5. There are not too many reliable domestic digital currencies. Generally, most excellent digital currencies are imported procts, such as bitcoin, Leyte currency, ether currency, etc
however, Yuanbao coin, Ruitai coin, bitcoin and the tokens of different crowdfunding projects in Europe are excellent digital currencies.

6. 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.

7. As for the so-called bitcoin, it is not protected by law now, so it can not be purchased because there are some illegal means to raise funds and operate illegally.
