 I'm Jinjian from the China Academy of Information and Communications Technology, shortly CAST in China. I'm going to give a speech on blockchain infrastructure in China, specifically how blockchain facilitator industry in China and further achieves the interest of everything. Since my presentation time is a press title, Q&A parties are not prepared, so if you have any questions, please leave your comments in your chat room or you can contact us via my email. Let's start with an overview of China blockchain industry and then a basic introduction on how blockchain works in the industry in China. Basically, a new blockchain infrastructure and a facility, BIFU, finally our industry alliance named the Alliance of Blockchain Industry, ZIPAC, and some co-operations between ABI and HyperLager. Literally, blockchain has become one of the key industries in digital economy development in China. Their Chinese government came up with the policies to clearly illustrate that blockchain is key to accelerate digital development and further build to digital China. The left two diagrams show our raw size of digital economy in China. In 2019, their digital economy accounted for 36% of GDP in China. This growing rapidly, the right diagram displays key industry areas given by Chinese government in this year. And as you can tell, China will put more efforts to the development of the blockchain industry. Here is a number of blockchain policies and their distribution for different provinces. In last year, there are total 220 policies published in China. Most of them are from Beijing, Chongqing and Guangdong province. In terms of enterprises in 2020, there are almost 4,000 blockchain enterprises in the world, among which 30% are Chinese blockchain enterprises. Because of COVID-19, the number of enterprises has slowed down in the year of 2020. These slides are some applications for enterprise formula comparison between global and Chinese industry distribution of blockchain applications. We can say that globally digital assets are the most considered area of blockchain adoption. Other notable areas include the traditional financial industry, intractor, supply chain, and logistic. Wherefore China 24% of Chinese blockchain companies are in the financial sector and 10.6% are in the digital assets and the intractor sector. In addition, companies in supply chain finance, trace bridge, supply chain and logistic, government affairs and public service also account for a higher proportion than those in the world. Investment and financing are both an element of consideration in the blockchain industry. From 2010 to 2020, United States, Canada, China, Switzerland and South Korea are five countries with a large amount of investment and financing in the global blockchain industry. In terms of the number of investment and financing transactions, the number of investment and financing transactions in the United States, China, the United Kingdom, Singapore, and Canada is more than that of other countries. Then let's take a deeper look at China. Over the past decade, the scale of investment on financing in China's blockchain industry has expanded rapidly. In 2020, due to the pandemic, there were 31 investment and financing transactions of blockchain enterprises in China, amounting to 149 U.S. donors, down 48% and 39% respectively, compared with 2019. As we can see from these pictures, the tendency of blockchain related to paper is increasing each year. Between 2013 and 2020, the total number of high-level papers published in the field of blockchain was over 9,000 globally, with 26% published in China. In 2020, over 3,000 papers were published globally, and the third percent were published in China. As for different countries, China and America published their most papers in the world. Because of the rampant development, the number of blockchain patent applications in major countries around the world remains at a high level from 2019 to 2020, by 2020, the total number of applications will be close to 20,000. China has the highest number of blockchain patent applications in the world. We can see that words such as smart contracts, keypads, are the words in the blockchain patent. Also, blockchain industry parks play a key role in the industry development in China so far. China has set up a search eight blockchain industry parks in 18 provinces. You can see the park distribution. Next, I'm going to give you the latest development information on the industry in China. Here, the industry is mainly about manufacturing. After the release of the action plan for the innovation and development of the industry in China 2018 to 2020, the industry is playing an increasing role in providing the network basis, central platform, code data, and protection. New industry infrastructure has been strengthened and the processor is fruitful. For the achievements, high quality outer network covers over 360. 50 generation plus industry insider projects underway totals 1,000 and 100. Finally, those are working very well and the disaster-prepared needs nowadays in Nanjing and Guiyang starts to be built. 98 secondary loads are in test operation currently in 22 provinces and 33 industry sectors. Industry insider platform with the influence in markets exceeds 80. It has connected 60 million pieces of equipment under development 3.5 million applications. National security sensor platforms covers 31 provinces and 35, 110,000 industry business. As you can see from the left, this is the national industry insider identifier system. We have five identifier loads in top level loads in Beijing, Shanghai, Guiyang, Guangzhou, Wuhan, Chongqing, and two backup and recovery loads in Nanjing and Guiyang. We have 20 beginner identifiers have been registered and allocated over 12 million times of identifier resolution per day. First, secondary loads total 134, covering 22 provinces and 44 industries, including shipbuilding, containers, petrochemicals, food, and medical instruments. For enterprise nodes, over 15,000 business are being connected to the identifier system of industry insider. I'm not sure the slides are okay. Yeah, it's just, now you consider, next slide. Okay, thank you. Oh, I'm sorry. Now it's, yeah. Okay, next. Moreover, we are trying to apply blockchain into this existing running system as a trust infrastructure. Blockchain will create a more trustworthy environment for their identifier resolution, also supply and change automatically integration. So we build blockchain infrastructure based on identifier resolution, which will provide a blockchain-based service, including identifier resource allocation, management, and interability. Blockchain combines industry interact, will dramatically change how people and the machine interact with each other and with themselves. It will achieve an interact of everything world. Okay, next, I will give more introduction of this new blockchain identifier infrastructure, BEFU. BEFU is short for blockchain identifier infrastructure as well as blockchain infrastructure and facility. It means we hope BEFU would become a new global blockchain infrastructure, which integrate blockchain technology to promote the transformation and development of enterprise and industries. When you combine digital infrastructure, industry, and blockchain, then you'll get this innovation blocked through BEFU. BEFU is a permission of public blockchain about BEFU architecture, providing cross-chain interoperability services through identifier management system. BEFU has a two-nature architecture consisting of primary chain and sub-chain. Primary chain is composed of several super nodes. Super node is used for in-tangent computation and serve as a root node for industry interact. We also have a concept of backbone node. Backbone node is used for their connection between primary chain and all kinds of other blockchains, from regional blockchain to industry global blockchain. Okay, I'm sorry, slides. I think now it's slide 18. Now the slide is page 18. Okay, thank you. Here are some technical features of BEFU. BEFU is a combination of public blockchain and a permission of blockchain. BEFU has the ability to integrate with different kinds of blockchain architectures, and it also supports different consensus algorithm. For data storage, BEFU supports massive data storage and cross-platform data rate and writeability. Plugable smart contract agent supports mainstream of smart contracts, decentralized identifier DID to achieve a licensed service. BEFU system consists of enterprise of technical components and expression, you know, which application and the public service, promoting the construction of super nodes, backbone node and open blockchain applications. Here is a basic timeline of BEFU development in August 2020. BEFU was officially launched. After one month, the first super node was signed with Chongqing local government, then we had Beijing super node launched, Kunshan backbone node launched, and we also integrated with different regional blockchains applications and industry blockchains such as the income chain from China income, Sichuan province blockchain, Shuxin chain, and China merchant banks blockchain integrated with BEFU. The last part is some basic introduction about one of China's largest blockchain alliance, alliance of blockchain industry repark. ABI was established in 2016. It's an independent legal entity jointly initiated by our 70 enterprise universities and research institutes, and it's the first non-profit legal entity in China's blockchain area. ABI now is operated by China Academy of Information and Communications Technology, CACT, aiming to become a world famous blockchain community. The right to the diagram shows the ABS organization structure. There are 10 working groups, seven industry promotion communities that aim to promote blockchain technology. We also formed a regional cyber alliance to accelerate blockchain adoption in different local areas in China. As of May 2021, the alliance has enrolled more than 210 members with more than 80 core units located in 22 provinces. Myeongchang city panids are auto nanomics regions across China. It covers telecom operators, largest state-owned enterprises, central enterprises, key universities, and institutions. In fact, giant companies top-level blockchain enterprise and other well-known enterprises and institutions in their information and communication field and industry, as well as relevant institutions and organizations. In addition to the traditional international cooperation in the ICT field, ABI relies on ThinkPunk and the industry resource of the CACT to actively explore cooperation and exchange in this field. It has established linkages and carried out exchanges with overseas core technology organization, industry alliance, well-known universities, and so on, to expand channels for enhancing international discourse power of domestic blockchain field. At the beginning of this year, ABI joined the high-plagiar, ABI and high-plagiar together, trying to facilitate the development of China's blockchain industry and build a bridge between Chinese blockchain and international blockchain development. On April, ABI and the high-plagiar co-hosted an international online meeting, China blockchain industry embracing the world. It was a big success, attracting audiences from 30.
