Open up the second line of the governor and build a city of wisdom on the blockchain

“The first subway construction in London 160 years ago, the first time that Manhattan was built in 135 years ago, the urban brain will become a brand new urban infrastructure.” Two years ago, Wang Jian published a thought on the urban brain in People’s Daily. As the outlook is like.

The urban brain has come from a vague and great idea to today's clear outlines and open branches. The era of smart cities has arrived.

Urban development and technological progress, as if determining the double helix of biological evolution, jointly promote the development of human civilization, and the smart city is the product of this double helix. When the speed, scale and resource carrying capacity of urban development do not match, problems such as rapid population growth, serious traffic congestion, environmental pollution, and information security will frequently occur.

Although Wang Jian has repeatedly emphasized the difference between the concept of urban brain and smart city, they all belong to a new concept or model that uses cutting-edge information and communication technologies to solve urban disease problems.

Specifically, they are driven by the three elements of the Internet's complete infrastructure, unprecedented computing power of cloud computing, and massive data resources. Through some data in the middle, the perception, communication and analysis of all aspects of urban information, Coordinate the benign operation of many application subjects in the city to solve the existing pains of urban diseases.

In recent years, the application of blockchain technology has gradually become a boom.

According to the PricewaterhouseCoopers research report, blockchain technology will be the next innovation to promote smart city construction.

Countries such as Estonia, Georgia, the United Arab Emirates, Sweden, the United States, and the United Kingdom have begun to apply blockchain technology to smart city construction.

Kevin Kelly believes at the Guiyang Digital Expo that the changes brought by blockchain technology are not revolutionary, but gradual. Numerous cases show that blockchain technology is quietly promoting the real landing and transformation of smart city construction.

Wisdom government: breaking the information island, the residents run at most once

The iResearch 2019 Smart City Report states that the overall architecture of a smart city consists of five levels: the perception layer, the communication and network layer, the urban data and control layer, the urban application layer and the support layer.

Among them, the application layer types of smart cities are divided into four parts: smart city infrastructure, urban basic public services, urban governance mode enhancement, and smart city connotation sublimation.

Smart government is undoubtedly part of the application level of smart city infrastructure. Since there are many projects in the infrastructure and basic public service sectors, the government and enterprises are the two important players involved in the construction of smart cities.

Liu Yi, a CTO of a company, introduced a series of data carried out by the government to improve the licenses and certificates of government and people's livelihood, which were promulgated and managed by the government. Many areas such as property rights registration, industrial and commercial registration, and judicial justice often form data islands, which cannot be opened up. The procedures for urban residents are cumbersome, and there are often cases of “kicking the ball”.

On the other hand, how to promote the transparency and openness of government power through innovative technologies, strengthen the supervision and control of power, and let power operate in the sun has become a common concern in society.

The concept of smart city construction is to establish a data center, promote the integration and sharing of government information systems, open up information islands, improve inter-departmental collaborative service capabilities, and improve the efficiency of work for enterprises and the public, thus improving people's livelihood.

So how does blockchain technology empower smart government?

Liu Yi explained, “Using the blockchain technology to pass the license data to the mode of light certification, it can realize the self-management of the license data and the mutual trust and mutual trust of the materials. Authorized use, so that most of the items do not need to run, some of the items run at most. The license data needs to be authorized by the data provider and the data owner to share the usage on demand, and obtain real-time authentication on the chain, thus preventing individuals Data leakage and protection of personal data privacy."

For individuals, urban residents can implement trusted digital identity authentication on the chain to solve digital life problems. Compared to centralized data exchange sharing, blockchain-based data sharing can solve the trust of data sharing and use between departments. Breakpoints not only improve the convenience of government agencies, but also trigger cross-departmental approval model changes in the future.

Liu Yi said that at present, they have participated in the construction of smart platforms and government service platforms in nearly 10 key cities such as Beijing, Fuzhou and Zhangzhou. The pilot has realized the application of blockchain technology in the field of smart government.

According to the zinc link, the landing case of the government blockchain is not unique in China. As early as June 2017, Chancheng District, Foshan City, Guangdong Province hosted the “IQI Zen City IMI” identity authentication platform, which uses blockchain technology to build a unique digital identity ID to prove the city residents “I am me. ".

In February of the following year, Xiong'an New District actively built a blockchain rental platform, recorded the listing information and lease contract information on the blockchain, and could not be tampered with by multiple parties. Since then, Xiong'an has launched a new blockchain management platform to solve the problems of fund misappropriation and contract breach of traditional engineering projects.

In these cases, the blockchain technology is located in the urban data and control layer of the overall structure of the smart city, and explores and innovates to improve the smart city government affairs.

Smart transportation: an important step to improve people's livelihood

If smart government is an important measure for the government to embrace new technologies and improve government management and power issues, urban traffic problems are the most important areas where smart city construction and people's livelihood are most closely integrated.

On March 18, 2019, Shenzhen Taxation Bureau, Shenzhen Transportation Bureau, Shenzhen Metro and Tencent Company held a small ceremony to use the bus code to take the subway and use WeChat to issue blockchain electronic invoices at Shenzhen Futian MRT Station.

Zinc Link Learned that after taking the subway code, go to the “View Travel Record” page, click “Invoice”, and after “Drawing Type” and “Invoice Header” on the “Open Blockchain Electronic Invoice” page You can issue a “blockchain electronic invoice”.

At that time, Cai Tongge, the head of the blockchain of Tencent, introduced the zinc link. This blockchain electronic invoice mode is invoiced on the chain. The tickets issued will be strongly bound to the transactions and payments before the billing. For verification, this ensures the authenticity of the invoice from the transaction and payment links, and eliminates the existence of fake invoices.

Public transportation is an area closely related to improving people's livelihood and an important scene for residents' lives. Tencent data shows that after the blockchain electronic invoice is launched, passengers no longer need to queue to the station customer service center to receive paper invoices, saving the invoice paper cost of 400,000 yuan per year for the Shenzhen Metro.

Song Lingyun, general manager of Tencent Smart Transportation, said that public transportation and subway are equivalent to the human body's "Ren Duo two veins" in the field of smart transportation. Using financial technology, using blockchain technology and the bottom of the passenger code, "based on user traffic, there will be very A good historical precipitation is a major innovation in Tencent's development of smart transportation."

In addition, in addition to blockchain electronic invoices, blockchain technology can also be applied to the integration of transportation systems. The original concept of the construction of Hangzhou urban brain system is derived from the governance of traffic jams in Hangzhou.

Xiao Ziwen, PlatON's chief strategy officer, introduced the zinc link. “Transport integration is a very important part of the smart transportation system. Ships, airplanes, cars, etc. in transportation, as well as road networks, stations, ports and airports for transportation. In the organization, management and scheduling, the sharing of traffic information resources is the key."

For a long time, the transportation industry has been subdivided into different departments, and the departments have shown system independence. Multiple systems have formed information islands. Xiao Ziwen said that the combination of blockchain privacy and security computing technology can ensure that data sharing is realized between major systems without data leakage. Data can only be valued if it is circulated.

Dong Zhifei, chief engineer of Dahua Securities Smart City Research Institute, explained the zinc link, the construction and management of the city, and the process of economic activities and operations, trust is the most important component. How to establish a trust mechanism and how to protect it is very important. Regardless of government affairs, transportation, medical care, finance, etc., blockchain technology can make information inherently credible, and redefine trust relationships, from traditional trust intermediary to de-intermediation.

In the form of the underlying technology, the blockchain reshapes the smart city information use framework, and will also promote the innovation and development of the new digital economy and new models.

Smart home: Each device has an IoT "passport"

The construction of smart cities started in urban governance, but it is not the final solution of urban diseases. With the development of the industry, the scope of smart city construction has further expanded.

Under the division of iResearch, the smart city infrastructure relative to government affairs, the urban basic public services of transportation, and the smart family belong to derivative business applications and lifestyle applications, which is the embodiment of the sublimation of smart cities.

Smart home is a private space of relative privacy. It collects data and information through the form of smart home, forming the interaction between people and machines, machines and machines, and facilitating people's family life.

Even in relatively private areas, smart homes have different brands, and the cross-institutional and cross-brand communication and sharing of data and information between them faces difficulties.

Haier Group divides the smart home field into smart living, smart bathroom, smart care, smart kitchen food, and smart security. Haier Haichuang Chain Zhangye introduced the zinc link. In the future, in a certain scene of smart home, such as smart kitchen appliances need to interact, not a product can be solved, but by many home appliances gas stoves, range hoods, microwave ovens If you link together, you can solve the problem.

Sichuan Changhong also found that the greater value of blockchain technology lies in the establishment of an ecological relationship between brands and devices. Tang Bo, chief scientist of Changhong Blockchain Lab, said that to establish a cross-platform ecology, it is inevitable that multi-platforms will need to achieve technical interoperability in commercial games, and reach a consensus on the sovereignty of terminals and the right to use data. Blockchain technology can achieve mutual trust, transparency and incentive between platforms.

Each device is equivalent to having an IoT “passport”, which can be interconnected through a blockchain.

In addition to this, there is a smart door lock. The blockchain chip is placed on the smart door lock. It is equivalent to having an “ID card”, a password, and information entering and leaving the house can be synchronized to the blockchain for distributed storage in real time. It can not only manage the house through the door lock, but also avoid the centralized cloud storage and lead to data privacy leakage.

Dong Zhifei introduced the zinc link. The large-scale popularization of 5G technology will promote the construction of Internet of Things with wide coverage, low power consumption and low cost. It will truly integrate 5G and the Internet of Things to achieve information and connect objects. The blockchain transforms the trust of people and people into adult trust in the machine, greatly reducing the cost of trust and improving the efficiency of the society.

The concept of “city” has evolved over thousands of years, from the original population-concentrated commodity trading region to a geographical space composed of core elements such as people, environment and information.

With the advent of the digital information age, the world has entered a new ternary world from the dual world of human society and physical world. In the economic operation of the world, big data is raw materials, cloud computing is productivity, artificial intelligence production The way, the blockchain represents the production relationship.

Blockchain technology promotes the change of new production relations, playing the role of “data manager” in the era of smart city, whether it is smart government, smart transportation, smart family and other important scenes in smart city construction, blockchain Technology, like the Internet, finance, and communication technologies, has become an indispensable and increasingly basic underlying technology in the ternary world. The real landing and transformation must happen quietly.
