1. "blockchain" is an important concept in the new era. In essence, it is a centralized database, and also an underlying technology such as digital currency. According to our popular explanation, "blockchain" can be regarded as an account book. Every bill is every block, but this account book is centralized, and it can be said that no enterprise or team has jurisdiction over it“ "Blockchain" technology is a unique information technology, such as centralization, information can not be changed in series. Now this technology has been applied to a series of applications such as electronic invoice, payment code and so on
in today's life, many people use this pretext to cheat, such as direct selling, capital, technology, etc. There is no right or wrong in technology, but in people
with the progress of the times and society, the beginning of the application of any technology will be questioned positively and negatively. However, with the relative application and maturity of technology and the improvement of technology, the various applications around people will continue to improve. I believe that in the near future, these doubts will graally dissipate
the following is a summary of some blockchain scams around us
trap 1: block chain is the coin trap
trap two: virtual currency transactions, promise low investment, high return
trap three: centralization can solve all problems
trap four: block chain extension procts can be laid down with a mining machine to earn money
trap five: WeChat, Alipay trading transactions virtual currency

2. Blockchain is a technology to achieve decentralization, and it is an application model of a variety of Internet basic technologies. In essence, blockchain is actually an application model similar to internet protocol. The HTTP we usually log in to is an internet protocol. The Internet connects the global network through the underlying protocol, while the application protocol of blockchain is a new way to connect the network nodes distributed around the world. In the future, more and more people will understand and accept blockchain.

Blockchain is on fire! It's so hot that I have no friends! In recent days, it has been swished by various popular science jokes of blockchain, just like crowdfunding, equity and original stocks in the past two years. If you go out and chat with others, you will be embarrassed to chat with others if you don't talk about blockchain. Textbook like explanation: an intelligent peer-to-peer network that uses distributed database to identify, disseminate and record information. It is a distributed database system with different nodes and an open ledger
the concept of "after the rules are settled, everyone will register spontaneously" in wechat organization corresponds to the concept of "decentralization, no single user can control it" in the blockchain. "Registration in wechat group" in wechat group corresponds to the concept of "peer-to-peer network" in blockchain. "As long as the network is connected, we can know the latest progress" in wechat organization Bureau, corresponding to the concept in blockchain, namely "game mechanism"
4. 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.

5. It's so funny that I cheat and fight
6. Call the police. It depends on your luck if you can get it back. If the police can recover the money after solving the case, they may give it to you.
7.
what is the latest "frequently named" blockchain? Blockchain is a new application mode of computer technology, such as distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm, etc. Blockchain is essentially a decentralized database
in fact, we are committed to liberating the blockchain from the masses to the masses. Its fundamental purpose is to expand or even reshape the trust system and improve efficiency. It is more like a way of thinking or concept that starts from people's vision. In fact, the core advantage of blockchain is that its credibility and written data can not be tampered with. As one of the hot spots of scientific and technological innovation, Hengyuan technology has gathered a large number of talents, capital and social resources in the blockchain instry. I believe that with the strong support of the central government and the strong promotion of policies, blockchain technology will play an important role in the construction of Digital China and achieve more fruitful results
8. I've heard that there's no way. The country that speculates in money is not allowed. Now it's going in the right direction guided by the state. All regions are vigorously developing the blockchain. Changsha high tech Zone has also set up a SMIC blockchain project, which is for enterprises to collect money on the chain. Only when this kind of official entry project is invested, can we feel at ease.
9. No, not even blockchain fraud
