Why are so many blockchains emerging now

1.

What is the prospect of blockchain technology? The following is just personal experience and opinions, for reference and learning only

I have been in touch with the blockchain instry for many years, and I have my own views and understanding from its ups and downs. I personally think blockchain technology is still very good. The reasons are as follows:

first, blockchain technology as a rookie after the Internet, the Internet is the transmission of information, and blockchain is the exchange of value. The development trend of blockchain is similar to that of Internet

2. After the blockchain has gone through great waves and been widely misunderstood, there are still many blockchain explorers and practitioners in the instry making continuous efforts

Third, with the attention of the country and other countries to the blockchain instry, governments all over the country have set up blockchain development funds to promote the development of the local blockchain instry, so as to occupy the highland of the blockchain instry

Fourthly, the Internet of things is the development trend in the future. In the face of the growing demand of the Internet of things ecosystem, the computing power of the central server is severely challenged, and decentralization becomes the key to solve this problem

the above content is only a new point of view, or it needs specific analysis of specific issues. After all, practice is the only standard to test the truth

2.

Blockchain is not deceiving, but deceiving people under the guise of blockchain. In fact, blockchain scam is to make use of people's ignorance of the technology, and then fraudsters rely on various and fancy means to set up scams. Many people only look at the surface when making investments, and finally fall into the trap of high profits

in the current society, more and more people are willing to take this risk to make investment in order to get rich returns, but not all of them can make profits. After all, where there are interests, there are many people waiting, and they will set traps for people to take the t

extended data:

precautions

blockchain is a technology. In short, this technology is a new way of data management based on cryptography. Blockchain technology has broad application prospects because it has the advantages of decentralization, non tampering, tracing and so on. And issuing currency is a kind of behavior derived from blockchain technology. At present, the vast majority of blockchain applications which mainly focus on currency issuance and speculation are suspected of illegal fund-raising

blockchain technology is still in early development, and it is difficult to apply it. If you only rely on a white paper to claim that there is an application, it is a deception in itself

3.

Because the blockchain technology is not mature at this stage, and the infrastructure is not perfect, many applications are limited, and the overall application is still in a very early stage

First of all, the main function of blockchain is to store information. Any information that needs to be saved can be written to or read from the blockchain, so it is a database. Secondly, anyone can set up a server and join the blockchain network to become a node. In the world of blockchain, there is no central node (decentralization). Every node is equal and keeps the whole database. You can write / read data to any node, because all nodes will be synchronized in the end to ensure the consistency of the blockchain

4. Personally, I think the development of blockchain is still very good. Now it has risen to the level of national development strategy. In terms of ecology, you can learn about Wen ecology. I think the relatively complete ecological construction that I have come into contact with at present is Wen ecology.

5. 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. At the same time, as the underlying technology of bitcoin, it is a series of data blocks generated by using cryptographic methods. Each data block contains a batch of information about bitcoin network transactions, Used to verify the validity of its information (anti-counterfeiting) and generate the next block.

6. It depends on what you think of blockchain. Some people are optimistic about blockchain, while others say it's a fraud. If you recognize this technology, you can invest in it. In fact, I personally think blockchain can be implemented in the future, which is of great value. For example, the prospect of commercial application and the profit model of Honghua coin, which unites the Chinese instry in the world, are very clear.

7. The application of blockchain finance is the key field that it plays a role in reality. The financial instry needs such high-end technology, and the traditional mode of operation will have profound changes because of such technology. The application of blockchain finance has many distinctive characteristics, which makes people talk about it with relish. Moreover, it attracts people's attention because of the actual effect, which has a growing impact

Abstract: developed countries and technology companies have been ahead in the research and application of blockchain technology. From the perspective of patent application, there may be a gap of about one and a half years between China and the United States in terms of blockchain technology. Based on the above situation, how can China achieve "asymmetric" catch-up? First of all, we should see the situation clearly, seize the opportunity and meet the challenge. Secondly, after understanding the necessity of building the bottom layer of the blockchain for the existing business and future development of the financial instry, a consensus of "China's financial blockchain alliance" was reached among financial enterprises. Finally, we should work together to meet the change

how to understand blockchain

bitcoin: a peer-to-peer e-cash system. In 2009, after the paper was published, bitcoin was born as a virtual currency in the digital world of the Internet. At present, bitcoin's total market value is about US $6.5 billion. Although its market value is constantly changing, it is still the largest virtual currency in the world

another important concept is blockchain. Blockchain is an underlying technology of bitcoin, and bitcoin is only an application of blockchain. As we all know, bitcoin can achieve point-to-point value transmission. In addition to bitcoin blockchain, there are many other blockchains, such as Ethereum blockchain. Therefore, we should distinguish the concepts of bitcoin, bitcoin blockchain, blockchain and blockchain technology

at present, there are several misunderstandings about blockchain. Blockchain can be described in English as "decentralized blockchain", in which decentralized is translated as "decentralized". However, I think that the blockchain has realized the value dissemination without intermediary, that is, the point-to-point value dissemination. This does not mean that after entering the era of blockchain, there is no need for the center, but it should develop from a single centralization to the parallel between centers. Then, the existing center is likely to become a sub center or weak center. At present, all banks have their own data centers. If the financial blockchain alliance is established in the future, they can become the nodes in the blockchain alliance, so the blockchain does not need a center<

blockchain does not need credit

we often see some articles that think that blockchain is to "de credit". In fact, blockchain is to build trust through consensus algorithm and ensure the correctness of transactions through consensus among nodes. Build trust with low cost through mathematics and algorithm, rather than "de credit". However, the digital asset transaction between people does not need two people to know each other, or trust each other, and does not need a third-party credit institution. It only needs everyone to trust the trusted network of blockchain

why is it credible? Because it is a distributed database, there is a set of consensus based mechanism: a set of encryption algorithm, making it tamperable. On the one hand, the public key makes the information transparent and traceable; On the other hand, private key can protect privacy

blockchain is not a mature technology, nor is it omnipotent. At present, blockchain technology is still in the early stage of development. At the beginning of this year, we sent a delegation to study in the blockchain Research Laboratory of Barclays in South Africa. At the seminar, experts on the African blockchain of Barclays believed that it would take at least five to ten years for the blockchain technology to become a truly mature technology. At present, blockchain has the disadvantages of relatively slow computing speed and small storage space, and not all data processing needs to use blockchain

the research and application of blockchain in foreign countries

we find that the old financial developed countries have been ahead in the research of blockchain technology. The British government believes that it is very important for the government to participate in the legislation of digital currency and blockchain network, and encourages in-depth research on blockchain technology. The UK government is actively evaluating the potential of blockchain technology and considering using it to rece financial fraud and cost. In addition, the UK government plans to develop applications that can be used between the government and public institutions

in February this year, the European Commission put crypto digital currency at the top of the fast development target area, which promoted the policy research of various institutions on digital currency. Technology companies are also ahead in the research of blockchain technology

IBM launched the "open ledger project" to develop enterprise level blockchain software structure, promote the commercial use of blockchain technology, and support the docking of external data through the bluemix and API infrastructure of IBM cloud computing platform. IBM still has a lot of practice in blockchain technology. Recently, it and a South Korean company have made creative experiments using blockchain technology and Internet of things, and achieved some results

Microsoft uses Azure Platform to provide users with "blockchain as a service", which enables R3 and its bank members to speed up the process of experiment and learning, and accelerate the development, testing and deployment of distributed accounts

Intel also released sawtoothlake, an efficient molar platform for building, deploying and running distributed ledger; At the same time, Intel also studies to create a trusted execution environment for hardware chips of blockchain applications, providing higher security and privacy< At the same time, Wall Street is taking positive actions. Although it was established relatively late, the core function of R3 is to formulate instry standards for the development of banking blockchain technology, explore practical uses, and establish banking blockchain alliance

from what we know, in addition to these two new companies catering to the arrival of digital finance era, large financial institutions are studying blockchain technology and building their own blockchain concept and technical team

at present, there are practical application cases of blockchain technology

in Canada, blockchain start-up blockchain Tech Ltd has been listed on the growth enterprise market of Toronto Stock Exchange; The Estonian government will launch the government's blockchain healthcare record

domestic attention and Research on blockchain technology

blockchain is an optional technology. Prior to that, the people's Bank of China also held a seminar on digital currency. In addition to the central bank, Zhejiang Province, Beijing and other relevant departments also expressed their support for blockchain application research last year

from the perspective of enterprises, Bubi blockchain has been applied to equity, supply chain, points and other fields, and is concting experiments and application tests with exchanges and banks. Bubi blockchain focuses on the innovation of blockchain technology and procts, has a number of core technologies, and has developed its own blockchain service platform. Moreover, many blockchain innovation and entrepreneurship enterprises continue to emerge

in addition, a number of instry alliances are being established. In terms of financial institutions, the cases of blockchain application by large banks and financial institutions in China still need to be solved
by the end of 2015, Bank of America had obtained 15 patents on blockchain. There may be a gap of about a year and a half between China and the United States in blockchain technology
the application of blockchain finance is entering a new stage in an all-round way, various applications will be more and more in-depth, and the relevant changes will be more and more attention, and a great new trend will be formed.

8. The simplest way for Xiao to buy currency is to buy it on Ouyi okex. It can get to the account quickly and operate foolishly. It is the largest trading platform in China at present and it is very convenient to use.

9. Bitcoin plate is big, equivalent to the stock market, I think it is not suitable for novices. Virtual currency is still worth playing now. For example, the flow of virtual currency is relatively small, which is more suitable for people who are not willing to save and who are not willing to take too much risk.
