On December 17, baidu super chain college and Huayi kangdao Technology Co., Ltd. jointly hosted a seminar on “technology enabling cross-border integration – blockchain technology application and industrial integration innovation” in Chongqing. At the meeting, Yang Feng, director of Chongqing Yuzhong District Economic and information technology committee, Luo Lin, deputy secretary of the Party group of Chongqing Yuzhong District new petrochemical District Management Committee, Zhong Hong, President of Qinghua X-lab sinomenine Chain Alliance Research Institute, Yu Yanan, person in charge of Baidu blockchain products, Chen Haoyang, chairman of Chongqing Huayi kangdao Technology Co., Ltd. and other industry, University and research representatives attended, We will jointly explore new initiatives of blockchain and cross-border integration, and provide a good reference and recipe for the innovation and development of blockchain + industries.

In fact, Baidu has a long history with Chongqing. In August this year, Baidu and Chongqing Municipal People’s government signed a cooperation agreement on jointly promoting the innovation and development of big data integration. The two sides plan to cooperate in autonomous driving, smart city, smart government, smart city and smart cityBlockchainAnd so on. Chongqing gathers medical resources in the central and western regions, and has leading practical experience in medical alliance,Therefore, blockchain cooperation starts with medical treatment. Baidu gives full play to its technical advantages in the application of blockchain, bases on the construction of the innovation ecosystem of environment, heavy industry and medicine, integrates the resources of medical technology enterprises in its jurisdiction, and builds a blockchain medical network information platform.

Based on Chongqing, analyze the opportunities and challenges of blockchain development

Yang Feng, director of the economic and Information Technology Committee of Yuzhong District, Chongqing, and Luo Lin, deputy secretary of the Party group of the Management Committee of Sinopec new area, Yuzhong District, Chongqing, first spoke, respectively emphasizing the importance of the development of blockchain industry for the economic development of Yuzhong District, Chongqing, as well as the opportunities and challenges it faces.

Director Yang Feng said that in order to promote the deep integration of blockchain and economy and society, and seize the commanding height of the development of the national blockchain industry, the district government will strengthen the research and development of the core technology of blockchain, establish and improve the standard system, etc. In the future, we should help some promising enterprises to become bigger and stronger by setting up a leading group for the development of blockchain industry, formulating the overall plan for the development of blockchain industry, and introducing supportive policies for blockchain industry.

Zhong Hong, President of Qinghua X-lab Ivy League Research Institute, provides Chongqing with a good recipe for blockchain development from the perspective of top-level design. He pointed out that for the digital economy, 1.0 is the computer era, 2.0 is the Internet era, and 3.0 is the blockchain era. As a national digital economy innovation demonstration zone, Chongqing already has policy advantages, and the blockchain technology can realize the right confirmation and effective flow of data, so the data is transformed from resources into assets, and finally into the innovation mode and system of capital. This is a huge opportunity Chongqing needs to grasp.

Technology driven, to explore the industrial change caused by “blockchain +”

In the future, the state will focus on promoting “technology independent innovation” and “application governance innovation”, while Chongqing has the advantages of blockchain industry integration in industry, ecology, policy and other aspects. Baidu super chain focuses on the research of domestic self-developed blockchain technology, and has carried out in-depth exploration in industrial practice. Yu Yanan, who is in charge of blockchain products from Baidu, and sun Junyi, a senior R & D Engineer, shared their experience and offered suggestions for Chongqing.

Yu Yanan believes that in the future, the blockchain will become the infrastructure of a trusted city and the “hydropower coal” of the society. Relying on the completely domestic self-developed underlying blockchain Technology (xuperchain), combined with the industry-leading AI and big data capabilities, baidu builds the smart city sovereignty chain by deploying blockchain nodes in various departments, institutions and IOT devices in the city. Based on the trusted blockchain network, baidu super chain has promoted the intelligent development of government affairs, justice, people’s livelihood and finance.

In the field of intelligent people’s livelihood, baidu super chain and Huayi kangdao launched the medical electronic prescription circulation platform in Yuzhong District of Chongqing. First of all, through the blockchain + AI technology to realize the integration of all links and prescriptions, and realize data traceability in the whole prescription circulation process. At the same time, the relevant government departments, including the health care Commission, the medical insurance bureau and the Drug Administration regulatory nodes, are added to the blockchain network to ensure that the data circulation can be supervised. In addition, baidu super chain combines blockchain, big data technology and DRGs of medical insurance bureau to realize intelligent management of medical insurance fee control.

In the field of intelligent justice, baidu super chain has opened up the whole link of evidence storage, monitoring, evidence collection and rights protection. Beijing Internet court and Guangzhou Internet court have jointly built a judicial evidence storage platform, realizing cross chain collaboration and evidence synchronization.

Sun Junyi interpreted the characteristics and advantages of domestic self-developed technology in simple terms from the perspective of technology. With “self research” and “open source” as keywords, baidu adheres to “independent research and development and innovation of blockchain core technology”. Its xuberchain technology is supported by six core technologies: super node technology, in chain parallel technology, three-dimensional network technology, account authority system, pluggable consensus mechanism and integrated intelligent contract technology.

He also synchronized the latest development of Baidu super chain open source. In just over half a year, the open source code of Baidu super chain has been used by more than 10000 people, and under the joint construction and maintenance of developers, it is still iterating continuously. It has been updated to v3.5, with a cumulative submission of nearly 300 times, of which the contribution rate of developers has reached more than 10%. At present, developers have applied Baidu super chain open source technology to various commercial applications such as justice, traceability, medical treatment, big data trading, etc. In order to help developers better apply, the super chain open source team has also launched multi language SDKs such as go, C #, python, Java, etc. to meet the needs of developers in different languages. The follow-up plan is to continuously optimize the bottom chain, applicability and testing tools.

In addition, Zou faan, CTO of jinwowo, also introduced the design idea of jinchain, which can realize 10000 level concurrency through multi chain transaction and sub parent chain technology.

Improving people’s livelihood and enabling the medical industry with blockchain

In addition to discussing the integration of blockchain and industry, the meeting also focused on the important field of people’s livelihood “medical and health”. In recent years, the state has implemented the Internet-based medical and health services, but it is facing the hidden dangers of medical process information security and data security management.

Chen Haoyang, chairman of Chongqing Huayi kangdao Technology Co., Ltd., mainly shared how to combine blockchain with medical entity scenarios. The problems of the medical industry lie in asymmetric information, unbalanced supply and demand, and unbalanced utilization of resources. The demands of the demander and the supplier can not match, and it is difficult and expensive to see a doctor, so it is difficult to find a better way to solve them. Internet Medical based on blockchain can make information manageable, controllable and traceable. In addition, chronic disease management and community service platform involve multi department collaboration, not a set of system, a technology, or a subject can confirm the right, through the blockchain technology can achieve effective data circulation and interaction.

Yu Yanan, product director of Baidu blockchain, and Li Jianfeng, CTO of Chongqing Huayi kangdao Technology Co., Ltd., introduced the leading practice of the block chain electronic prescription circulation platform in Yuzhong District of Chongqing. Internet medicine has realized the online system of the hospital to open electronic prescriptions, and patients can get medicine directly from the pharmacy, but the ownership, storage and management of electronic prescriptions have not been solved. At the same time, each hospital establishes an electronic prescription circulation platform, and the data is not exchanged with each other, resulting in repeated registration of patients. Through the blockchain technology, we can establish a multi-party governance and data flow driven medical and health business cooperation platform. Hospitals, pharmacies, regulatory units and other nodes are multi center nodes, each node has different permissions through access control and account separation, and ultimately achieve multi-party data security interoperability, which is more in line with regulatory needs.

Finally, leaders from the Municipal Supervision Bureau and the hospital also had a round table discussion with Baidu and Chinese medical representatives. Experts said that the value of blockchain data, artificial intelligence and other technologies to health care reform is beyond doubt, but it is undeniable that the integration of health care and blockchain still faces many obstacles. At this time, more need to be done to design the superstructure and select the right medical scene. Field experts also put forward more ideas on the application scenarios. Using blockchain can also solve the difficulties faced by the medical alliance and even the home-based care, and ultimately achieve enabling medical supervision and benefiting the people.

So far, Chongqing station, the lecture hall of Baidu super chain college, has come to an end, but the heated discussion on blockchain continues. In the coming 2020, the blockchain will move from the “era of recklessness” to the “era of specialization”, with more industries deeply integrated with the blockchain and growing vigorously. Blockchain, the future can be expected!
