1. For G20 mechanism, Hangzhou summit is the node of transformation from crisis response to long-term governance. The G20 summit mechanism initially emerged e to the urgent need to deal with the crisis, while the mission of achieving sustainable development in 2030 requires the G20 to transform to long-term governance. This year, the G20 has further improved its governance structure and established more ministerial meeting mechanisms to strengthen its long-term governance capability. In order to achieve global development, the G20 Hangzhou summit also invited ASEAN, African Union, new partnership for Africa's development and the group of 77 to participate in the meeting, which better reflects the theme of "inclusiveness"
at present, all countries are living in the community of human destiny of "you have me and I have you". No country can walk out of the economic crisis alone and achieve sustainable development. Only in "innovation, vitality, linkage and inclusiveness" can we achieve common prosperity.

2. This should be cautious, just in the coin circle several authoritative query platform did not find any CLT information, it is best to stay away from

A: the main application fields of blockchain technology are finance, Internet of things and logistics, public service, digital right, insurance and public welfare

First, in the field of finance,

blockchain has great potential application value in international exchange, letter of credit, equity registration, stock exchange and other financial fields

Second, the Internet of things and logistics

blockchain can also be naturally combined in the field of Internet of things and logistics. Through blockchain, we can rece logistics costs, trace the proction and delivery process of goods, and improve the efficiency of supply chain management

Third, in the field of public service, blockchain is closely related to people's proction and life in the fields of public management, energy and transportation. However, the centralization of these fields also brings some problems, which can be transformed by blockchain

Fourthly, in the field of digital right, through blockchain technology, works can be authenticated to prove the existence of text, video, audio and other works and ensure the authenticity and uniqueness of ownership

In the field of insurance, insurance institutions are responsible for fund collection, investment and claim settlement, and often have higher management and operation costs

Sixth, the data stored on the public welfare field

blockchain is highly reliable and tamperable, which is naturally suitable for social public welfare scenarios. The relevant information in the public welfare process, such as donation project, collection details, fund flow, recipient feedback, etc., can be stored on the blockchain, and can be made transparent and public, which is convenient for social supervision

Shenzhen's IT leaders summit has come to its 10th year. As the annual program of China's Internet giants gathering in Shenzhen, Shenzhen and its star enterprise Tencent are trying their best to entertain those bigwigs who come from afar

Zhang Shousheng, Professor of Stanford University, USA:

the generation of blockchain can create a data market. In my mind, the ideal future world is that everyone has their own data, which is a completely decentralized storage. In this way, it is impossible for hackers to hack everyone's personal data and then use some encryption algorithms, In the blockchain, it can really protect personal privacy and make very good calculation

artificial intelligence needs data, but data is often monopolized by centralized platforms, which hinders innovation. Encryption economics creates a data market with correct incentive mechanism for data providers, and artificial intelligence can take off on this data market. In a fair data market, the value of data is measured by cross entropy. In our society, some minorities will be discriminated against. However, in the encrypted data market, the data they provide will receive the most attention. Encryption economics can offset all kinds of prejudices in current social economics

Ni Zhengdong, founder and chairman of Qingke group:

blockchain is a direction of technology. Technically speaking, how much value blockchain can have is still a question mark, which may have great value, but today, the application has not been implemented. We don't deny the value brought by blockchain. In terms of technology, I think it is very valuable and promising, but no one can know how big the prospect is

in the financial field, blockchain is absolutely subject to supervision and is not a free world. Political orientation should be correct. In the field of blockchain, we should adhere to the leadership of the party and accept supervision. Digital currency can not be anarchism, it needs the correct guidance and supervision of the government

now we all focus on the real economy, whether it's entrepreneurship or investment. I think the blockchain itself should create value. If a company issues a coin and doesn't know what to do, it will suddenly be worth tens of billions of dollars, which is completely divorced from value creation

as for the title of classical investors, it's just a joke, or to grab an eye and create some concepts. I believe that 99% of the projects or 95% of the projects will be done by classical VC in 2018

Yan Yan, founding partner of Saifu Asia Investment Fund:

blockchain is very popular, but in fact, institutional investors participate very little. At present, many of them are indivial behaviors. More than 95% of ICO in China is money making, and the really large first-line institutional investors actually participate very little. To be honest, these people can become first-line institutional investors. They are not fooled. They know more than you, see more than you, and read more books than you. How can they be so stupid? They make money from people with lower IQ than you

Wu Ying, chairman of the digital China Federation:

pays close attention to the blockchain and has made a certain investment layout here. Among the three or four companies invested, there are 13 patents. Among the listed companies previously invested, 2 are doing blockchain business. However, it will take some time for blockchain to break out. On the whole, it will take about three years for blockchain to have a direct impact on the economy, but it may be faster than the United States in some aspects. Focus on the application of right protection of works of art, and set up an angel fund to invest in blockchain in the future

talk about big data: the obstacle of data exchange lies in the system rather than technology

Wang Jian, chairman of Technical Committee of Alibaba Group:

data is the material basis of digital economy. Data can neither be shared nor opened, but the value of data can be shared. Uber and didi are great changes in human behavior. What have they changed? In fact, Uber and didi are not sharing cars. In the past, they came out from home in the morning to tell their parents where to go. But with Uber and Didi, you can actually share with a company about where to go today. This is the real change

Guo Wei, chairman of the board of directors and chairman of Digital China Holdings Co., Ltd.

from the perspective of the government, he highly recognizes the value of data, but it is very difficult to implement it. Data itself has a natural segmentation, different people have different cognition of data. Another very important point is the division of interests. Due to the huge benefits brought by mastering the data, some people are not willing to release them. If released, it means the loss of privileges, which is the most difficult part in the process of data access today

from the perspective of today's technology, there is no problem to achieve data access with our technical ability, whether it is traditional technology or the latest developed technology. But the most important obstacle is the system

Yan Yan, founding managing partner of Saifu Asia Investment Fund:

the opening of data is a double-edged sword, and social data should not be open to everyone, because data is useless to more than 95% of people, and there are less than 1% of people, so it is harmful to the society to give them data

5. 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.

6. It's money laundering

7. A real virtual currency must first have open source code, decentralize, and issue in constant volume. If the initial mining scale of this kind of currency is large, it can be split. If the mining difficulty increases in the later stage, it should be split. In fact, it mainly depends on whether it can circulate, which is recognized by people.

8. Master yuan, the father of Xia Zongchang and Yuan Shaoyun, invited master Daonan to send a female cotton demon in front of him to lure him to live, suck his essence Yang, and he was found out; He also manipulated clay figurines and paper men with magic to kill and defeat them. Yu Sheng finds master Daonan and subes him. When he learns the truth, he vows to fight to death to defeat yuan Shaoyun.

According to the official website of the Trademark Office of the State Administration for Instry and commerce, Tencent Technology (Shenzhen) Co., Ltd. applied for a number of trademarks this month, including infocoin, Bodong star, Bodong star, Boyuan, qbanking, linkbanking, etc

Tencent blockchain business architecture Tencent blockchain pays more attention to scene landing, and has explored in the fields of supply chain finance, games, legal deposit, digital assets, public welfare search, logistics, taxation, etc. In March this year, Tencent announced that it is cooperating with China Federation of logistics and purchasing to develop the block supply chain alliance chain and cloud single platform. Based on the cloud single platform, the electronic waybill will replace the paper waybill, and the electronic signature will replace the manual paper signature. Through the blockchain technology, the electronic waybill will have the characteristics of distributed, encrypted and tamper proof, so as to ensure the authenticity and security of the waybill data, and achieve "credibility, security, efficiency and cost rection". In May this year, Tencent and Shenzhen State Administration of Taxation jointly established the "smart tax" innovation laboratory. Both sides are jointly promoting the first domestic digital invoice solution based on blockchain, exploring a new invoice ecology, hoping that every invoice can be checked, verified, trusted and traceable, and using blockchain technology to manage the whole process of invoice circulation, so as to make the whole scene circulation of invoice data a reality
