Xiao Feng's speech on blockchain

1. What is the most essential difference in economic activities before and after the blockchain comes out
before blockchain, any transaction activity needs an intermediary. Without an intermediary, two strangers can not reach a transaction. Here comes the blockchain, replacing the intermediary with a robot, and using a set of mathematical algorithms to ensure that two strangers complete a transaction
blockchain is a machine of trust, which is its essence
"decentralization" is a result of blockchain. In economic transaction activities, the so-called "decentralisation" is nothing more than these meanings:
first, when we complete a transaction, we no longer need a third party, which is a center
secondly, all the economic activities on the blockchain no longer need the organization and system of "company" to help us complete various transactions
thirdly, when serving for a centralized organization, the centralized organization gives us jobs and wages to encourage us to better serve the cause, but the incentive mechanism on the blockchain is not established by the centralized organization.

2. From now on, the possibility of implementation is relatively small, perhaps because of this

3. Ueex blockchain technology application summit, through keynote speeches, round table forums, innovative projects and other forms,

4. There are two ways to store bitcoin: one is to put it in a cold wallet, which is relatively safe; the other is a hot wallet, which is platform account

5. Take the "blockchain Instry Conference" as the key words search, and you can see that there are many press releases. He still takes a positive attitude towards blockchain technology, and the financial godfather's point of view is really beneficial.

6. No problem

7. With the increasing maturity of blockchain, more and more enterprises begin to look forward to using this technology for innovation. So, what is the impact of blockchain on enterprises? What can it bring to enterprises<

blockchain has the ability to innovate trade, transaction and business processes

the two basic concepts supporting blockchain are "business network" and "account book" -- it is thanks to these two concepts that blockchain can become a wise and unchangeable way of trade, transaction and business process execution

network members exchange various assets through an account book that can be accessed by all members. When the network synchronizes the account book, all members need to confirm the transaction of tangible or intangible assets. This shared view helps to establish legitimacy and transparency, even when the parties are not familiar with each other

blockchain can improve visibility and trust in business

by providing visibility to all participants, blockchain can rece transaction settlement time from days or weeks to seconds. The technology can also eliminate the intermediate third party that is usually needed to verify transactions in the past, so as to rece the excessive cost

because blockchain is built on the concept of trust, it can help enterprises rece the risk of illegal behavior on the payment network, thus helping to rece fraud and cyber crime

speed, cost, efficiency and transparency are the most important advantages of blockchain within enterprises and in the company ecosystem where trade activities are carried out. It is precisely because of such advantages that far sighted enterprises are more looking forward to using blockchain technology to innovate infrastructure and better carry out business

the value of blockchain development lies in the growth of the ecosystem

as a business network, blockchain can accommodate a variety of different types of participants. According to the number of participants in the blockchain network, the value of the assets exchanged, and the need to authorize members with different credentials, the adopters of blockchain technology should pay attention to the differences between "licensed" and "unlicensed" blockchain networks

when these business networks continue to expand, the real value of blockchain will be realized. With a strong ecosystem, business networks can reach critical scale more easily, enabling users to build new business models and innovate transaction processes.

8. Development trend:
1. Development trend of core key technologies
from the point of view of the current technology and application of blockchain, its core is distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other existing computer technologies. With the deepening of blockchain application, new and higher requirements will be put forward for these core technologies. The research results in consensus mechanism, security algorithm, privacy protection and other related technology fields will play an important role in the leapfrog development of blockchain technology and application, and will be very critical to the continuous innovation and breakthrough of these technologies
(1) the development trend of consensus mechanism
in the public chain, the common consensus mechanism has the disadvantages of low performance and high energy consumption“ The "side chain" technology can only solve some problems under certain conditions. At present, most of the mainstream consensus mechanisms in alliance chain are based on pbft and its variants. Although access control can greatly improve the performance, it also sacrifices the efficiency, constraints, fault tolerance and other aspects of the consensus. It can be predicted that consensus algorithms and decision-making with universality and better performance for some typical scenarios will continue to appear
(2) the development trend of security algorithm
security is particularly important for financial application systems. On the one hand, most of the traditional security algorithms currently used have potential "backdoor" risks, which need to be replaced by more secure national security algorithms, and the strength of the algorithms also needs to be upgraded; On the other hand, we should also prevent some new technologies, such as quantum computing, from impacting or even subverting the traditional security algorithms
(3) development trend of privacy protection
at present, the privacy protection related to blockchain is still relatively weak. Especially for sensitive data, we need to balance privacy protection and compliance supervision. Information privacy protection technology, such as zero knowledge proof, homomorphic encryption, is also an important direction of follow-up development
the above core technologies tend to be low-level computer technologies, and their development requires considerable personnel and time investment, which will be a progressive process. The research achievements and cooperation of related enterprises, scientific research institutions and colleges and universities in these fields are very important for the development of blockchain technology
2. Development trend of general development platform
at present, many IT enterprises, consulting companies, communities and technology alliances have invested in the application research and development of blockchain, established and improved the general development platform, which has a great role in promoting the application of the whole blockchain technology
similar to IAAs (infrastructure as a service) and PAAS (platform as a service) of cloud computing, the blockchain general development platform is composed of infrastructure support layer, blockchain core component service layer, and corresponding development test suite, which can provide one-stop, low-cost technical services for building and deploying blockchain applications. At present, there are some such platforms. With the rapid development of blockchain applications and the strong investment of relevant participants, its service coverage, R & D convenience, operation and maintenance intelligence, as well as high stability, large capacity and low cost are the predictable development direction.

Wu Xiaoqiu, vice president of Renmin University of China and director of the Institute of finance, said at a media conference on the 8th that he has always kept a wait-and-see attitude towards blockchain, but highly praised the penetration of Internet finance. Wu Xiaoqiu stressed: the things people like must have its logic. I don't think these Regulations are appropriate to limit the amount of our third-party payment. I think our supervision and management should understand the trend of financial development and follow the trend

Therefore, if this assumption is not tenable, we must not make a literal interpretation of some things, and do not force them into the middle of the tradition. What the common people like must have its logic, and you must study why the common people like it? You should not put things that people like. For example, I also see restrictions on the amount of third-party payment. 500 yuan is the end of a day. Sometimes, two meals are more than 500 yuan. I don't think these Regulations are appropriate. I think our supervision and management should recognize the trend of financial development, follow the trend, and not go against the trend
