Three questions blockchain (economic hot spot)

recently, news about bitcoin is very eye-catching, and blockchain is on fire. In the capital market, the rise and fall of various blockchain concept stocks is like a roller coaster. It can be seen from the sensitive capital market that the blockchain is on the way and is highly concerned by all parties

"blockchain technology is essentially a kind of database technology, specifically a kind of ledger technology. The account book records the asset changes and transactions of one or more accounts. In fact, it is a kind of database with the simplest structure. The daily accounts we usually record in the small account book and the statements sent by the bank are typical account books. " Wang Jun, chief researcher of Tencent Financial technology think tank, said that security is a major feature of blockchain technology, which is mainly reflected in two aspects: one is the distributed storage architecture. The more nodes there are, the higher the security of data storage is; The other is the ingenious design of tamper proof and decentralization, which makes it difficult for anyone to modify data without following the rules

take the online shopping transaction as an example, the traditional mode is that the buyer purchases the goods, and then sends the money to the intermediary platform of the third-party payment institution. After the seller delivers the goods and the buyer confirms the receipt, the buyer informs the payment institution to send the money to the seller's account. The transaction mode supported by blockchain technology is different. Buyers and sellers can trade directly without any intermediary platform. After the transaction between the buyer and the seller, the system publishes the transaction information in the form of broadcast, and all hosts receiving the information record the transaction after confirming that the information is correct, which means that all hosts have done data backup for the transaction. Even if a machine has problems in the future, it will not affect the data recording, because there are countless machines as backup

when it comes to blockchain, many people associate it with bitcoin, and many even equate blockchain with bitcoin. He Fei said that bitcoin is a way of presenting blockchain, but blockchain is not the same as bitcoin. Blockchain is the underlying technology and infrastructure of bitcoin, and bitcoin is a successful application of blockchain, but it does not mean that blockchain can only be applied to bitcoin

What is the use of

blockchain

can solve the pain points and difficulties in many fields such as finance, public welfare, supervision, anti-counterfeiting, but there are many applicable conditions

financial service is the first application field of blockchain technology. The application of blockchain technology can solve the pain points in payment, asset management, securities and other fields

taking the payment field as an example, the cost of reconciliation, clearing and settlement among financial institutions, especially cross-border financial institutions, is high, involving many manual processes, which not only leads to high costs for users and financial institutions' back-end business, but also makes it difficult to develop micro payment business. The application of blockchain technology helps to rece the cost of reconciliation and dispute resolution between financial institutions, and significantly improve the processing efficiency of payment business. In addition, the cost and efficiency advantages brought by blockchain technology in the field of payment enable financial institutions to better handle the small cross-border payment which was considered unrealistic e to high cost in the past, and contribute to the realization of Inclusive Finance

for example, in order to solve the problem of high reconciliation cost among financial institutions, in August 2016, Weizhong bank and Shanghai Huarui Bank launched the inter agency reconciliation platform of micro loan, which is also the first application scenario of banking alliance chain running in the proction environment in China. Zhang Kaixiang, chief architect of Weizhong bank's blockchain, believes that the high cost problem that the traditional "batch file reconciliation" model has failed to solve for a long time is exactly where blockchain technology can be used. Subsequently, Bank of Luoyang and Bank of Changsha have also been connected to the inter agency reconciliation platform. Through the blockchain technology, the inter agency reconciliation process in the micro loan business has been optimized, achieving the goals of quasi real-time reconciliation, improving operation efficiency and recing operation cost. Up to now, the platform has been running stably for more than one year, with zero failure, and the number of real transactions recorded has reached tens of millions

in the field of public welfare, blockchain technology is also promising. The first application scenario of ant financial services involving blockchain is public welfare, which helps a group of hearing-impaired children get a donation, and then uses blockchain technology to promote public welfare to be more open and transparent. Hu Danqing, senior proct expert of ant financial services technology laboratory, said: "the blockchain public welfare platform is like a post office dedicated to mailing funds on the Internet. Every sum of money donated by users will be packaged into a package, which will be delivered through the blockchain platform. Every node we pass through will be stamped with a postmark and finally delivered to the recipient. This can ensure that every sum of money donated by users is transparent, traceable and difficult to tamper with. "

blockchain technology can be used to crack down on counterfeit goods. Hu Danqing introced that ant financial services has applied blockchain technology to the traceability of authentic procts. At present, some seafood procts from Australia and New Zealand, such as milk powder, are swept away with Alipay, so they can know if they are genuine procts. Different from previous businesses' self input of commodity information, blockchain allows multiple "bookkeepers" to complete bookkeeping fairly, independently and non repudiately. "

for financial supervision, blockchain technology can also play a role. According to the white paper of FISCO bcos, the underlying platform of financial blockchain, issued by the financial blockchain cooperation alliance (Shenzhen) in 2017, blockchain provides consistent and easy to audit data for financial regulators. Through the data analysis of inter agency blockchain, it can supervise financial business faster and more accurately than the traditional audit process. For example, in the anti money laundering scenario, the balance and transaction records of each account are traceable, and any link of any transaction will not be separated from the regulatory line of sight, which will greatly improve the anti money laundering efforts

some people in the instry believe that blockchain 1.0 is mainly aimed at digital currency; Blockchain 2.0 aims at smart contracts and can be applied in financial markets; Blockchain 3.0 will apply to more scenarios, and even create a "blockchain era"

He Fei believes that blockchain can indeed solve the pain points and difficulties in many fields, but blockchain is not omnipotent and has many applicable conditions

for example, the decentralization of blockchain technology is suitable for multi-party participation scenarios, and if it is only unilateral or bilateral participation, the value is not great. Due to the need for each node to check, blockchain technology is not suitable for those high-frequency trading activities

for another example, blockchain emphasizes openness and transparency, which is not suitable for scenarios with high data privacy requirements

will blockchain become a new outlet

technology is not yet mature enough. We must be alert to the concept of speculation. In particular, we should distinguish between technological innovation or fund-raising innovation. We can not block the chain chain concept of

block chain so that we will not become a "Internet plus". p>

in recent years, the development ecology of blockchain has been graally improved and enriched. Instry insiders believe that with national policy support, extensive attention and financial support, blockchain technology can achieve graal and stable progress. Although the prospect of blockchain technology is broad, we should also keep an ordinary mind

"despite the current blockchain craze, we still believe that it is still in a very early stage." Hu Danqing said that at present, there is a virtual heat in the concept of blockchain. Instead of using technology to solve practical problems, it is hot to raise money and speculate on valuation. In particular, most of the so-called ICO (initial token issuance) that are hot are innovation of fund-raising tools, which has nothing to do with technological innovation

blockchain technology can indeed create great value, but some risks can not be ignored

"blockchain technology is not very mature, and its application scenarios are relatively limited, so we should be more alert to the concept of capital market speculation." He Fei said that behind the blockchain boom, there will inevitably be some companies that want to speculate. They do not really carry out business, but just try to make a profit in the capital market. They should be careful to prevent the emergence of "bad money drives out good money", which will lead to the withdrawal of institutions that really want to carry out business from the market and affect the application of blockchain technology

Hu Danqing suggested that for the current blockchain craze, regulatory authorities should be more active in intervening, distinguish between technological innovation and fund-raising innovation, encourage government organizations, credible experts and instry participants to help the public identify, comprehensively curb fund-raising innovation in the name of blockchain, and let the actual controller of ICO bear responsibility for fund-raising behavior“ The basis for judging whether it is technological innovation or fund-raising innovation is actually very clear, that is, whether it starts with trust and whether it creates practical value by solving the trust problem. "

in order to better promote and use blockchain technology in the future, we need to continue to improve the infrastructure and strengthen the formulation of relevant laws and policies

Wang Jun believes that there is still room for optimization and improvement of core technologies of blockchain such as consensus algorithm; On the other hand, the processing efficiency of blockchain is difficult to meet the requirements of some high-frequency application environments in reality. At present, the mainstream blockchain technology platforms are originated in foreign countries. Domestic blockchain technology service providers should patiently start from the bottom development, achieve independent and controllable technology, and strive to lead the development of global blockchain technology. Enterprises with blockchain application scenarios should actively embrace new things and scientifically evaluate the demand for blockchain, instead of blockchain for the sake of blockchain

He Fei believes that the government can issue relevant policies to guide the enterprises who are interested in the R & D and application of blockchain technology, and at the same time, clarify some suitable application scenarios of blockchain and areas encouraged by the state

the white paper 2016 on the development of China's blockchain technology and application suggests that government departments at all levels should learn from the advanced practices of developed countries and regions and, in combination with the development of China's blockchain technology and application, timely issue support policies for blockchain technology and instrial development, focusing on supporting key technology tackling, major demonstration projects, the construction of "innovation and entrepreneurship" platform, and the development of China's blockchain technology and application System solution development and public service platform construction. At the same time, it is suggested that domestic key enterprises, scientific research institutions, universities and user units should strengthen cooperation to speed up the research of core key technologies such as consensus mechanism, programmable contract, distributed storage and digital signature

can bring money to the enterprise will become the outlet

In early 2014, the Central Bank of China set up a special research group on legal digital currency to demonstrate the feasibility of issuing legal digital currency by the central bank. On January 29, 2017, the central bank officially established the digital currency Research Institute. After the successful development of the prototype of legal digital currency, the digital currency Research Institute of the people's Bank of China has tried to deploy institutions in many parts of the country, and through the integration with R & D institutions and instries, it has achieved the research results of financial development technology. In 2018, the digital currency Research Institute of the people's Bank of China successively settled in Nanjing and Shenzhen. In 2019, the people's Bank of China announced that digital currency will be piloted in Shenzhen, Suzhou, Cheng and xiong'an

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

6. The subversive characteristics of blockchain lie in the following four aspects: first, transparency. The data record of the blockchain system is transparent to the nodes of the whole network, and the update operation of the data record is also transparent to the nodes of the whole network, which is the basis of the trustworthiness of the blockchain system. Because the blockchain system uses open source programs, open rules and high participation, the data records and operation rules of the blockchain can be reviewed and traced by the nodes of the whole network, with high transparency< Second, openness. The blockchain system is open. In addition to the fact that the private information of the parties directly related to the data is always encrypted, the data of the blockchain is open to all (except the blockchain system with special permission requirements). Anyone or participating nodes can query blockchain data records or develop related applications through the open interface, so the information of the whole system is highly transparent< Third, information can not be tampered with. Once the information of the blockchain system is verified and added to the blockchain, it will be permanently stored and cannot be changed (except for private blockchain systems with special change requirements). Unless more than 51% of the nodes in the system can be controlled at the same time, the modification of the database on a single node is invalid, so the data stability and reliability of the blockchain are extremely high
Fourth, decentralization. Decentralization is the most basic feature of the blockchain, which means that the blockchain no longer depends on the central processing node and realizes the distributed recording, storage and updating of data. In the traditional centralized network, attacking a central node can destroy the whole system, while in a decentralized blockchain network, attacking a single node cannot control or destroy the whole network. More than 5% of the nodes in the master network are just the beginning of gaining control. 2019 is the first year for the commercial application of blockchain technology, and the stimulation of favorable policies will make the development of blockchain technology more stable
with the application of blockchain technology graally penetrating into many fields such as digital finance and Internet, we have a clearer understanding of the value of blockchain
blockchain has formed a situation of global competition, and all countries are seizing the development opportunities, let alone China; Therefore, there is no doubt that blockchain has become a national strategy.

Now, almost all of them cut off leeks one after another, saying that there is another new leek growing into...

the concept of blockchain is too new. A wave of smart people can easily use this concept to create some so-called creative gimmicks. In fact, it is essentially grafting the name of new concept to do something illegal without any egg

generally speaking, all the blockchain instries that are not combined with entities are hooligans

when it comes to on-the-spot projects, such as court power confirmation, agricultural proct traceability, electronic invoice, etc., have been implemented, but these are all about people's livelihood. There are also some project parties, such as tuken Mall (distributed scene e-commerce, online in May), gongxinbao (personal data right confirmation), Hashi future, etc., which are good on-the-spot projects, You can go to their official website or official account.

if you are looking for an investment, you have to take it easy. If you don't understand it, don't make a blind investment. If you understand it within the scope of your balance, you can make another investment... Remember

you can observe the projects mentioned just now, as long as the implementation can promote the real economy, I hope it can help you

8. Most lovers go to Zhuang by car first. What do you think Fengshen has at present? Many students communicate with each other to create a space project. There are all kinds of absolute landscape risks. Therefore, the doubles project has been closed to the county. There are all kinds of creation competitions. The youth project is a landscape project. There are all kinds of illusions of College Students' competitions. It has been sent to the East landscape risk.
9. Changsha high tech Zone has initiated the construction of a SMIC blockchain platform project, which aims to build a blockchain application platform for tens of thousands of enterprises in Changsha high tech Zone.
10. There are few special counseling centers for teenagers, but general counseling institutions can also do counseling for teenagers< The main tasks of adolescent psychological counseling are to stimulate interest in learning, correct learning attitude, eliminate weariness, truancy and learning obstacles, coordinate the relationship between classmates and parents, rece stress in college entrance examination, students' career planning, counseling for college entrance examination, adolescent sexual psychological ecation, and improve the quality of life Correction and improvement of bad conct, character building, treatment of adolescent neurosis< Br > < br > a good psychological counselor is very important, so we can choose Bowen psychology, which puts the frontier evidence-based medical knowledge into practice in psychotherapy, formulates better medical standards than the instry, starts from patients, and strictly follows the international diagnostic standards of mental disorders (dsm-5, ICD10). Provide meticulous and simple medical treatment process, multi-channel appointment service, rece the waiting time of patients. It has a private and humanized treatment environment, patiently listens to the needs of patients, and provides the whole process tracking service, which makes the medical treatment process more accurate, more convenient and more pleasant< br>
