Cities are actively embracing digital technologies such as blockchain, Internet of Things, artificial intelligence, etc. to accelerate urban economic growth and improve the quality of urban life and the sustainable development capacity of the environment. The digital transformation of the city also provides a good experimental field for the value mining and application of blockchain technology.

The construction of a digital city needs not only the coverage of connected devices in the whole city, but also the whole process of data collection and decision-making automation. The data on the blockchain has the advantages of being difficult to tamper with, safe and credible, and can help the construction of digital cities in the following aspects:

The blockchain adopts a distributed storage structure, so every node in the system has all the data on the system, which makes the data open and transparent and convenient to manage. At the same time, cryptographic technologies such as blockchain integrated privacy calculation can realize data security without revealing data privacy, or allow authorized nodes to obtain corresponding data by setting access rights, thus ensuring data security.

Thanks to the distributed network structure, even if a single node or a small number of nodes fail, the whole blockchain network can still operate normally, greatly reducing the risk of system failure caused by network attacks or technical problems. Compared with traditional cities, digital cities are more dependent on technology, and improving system stability is also helpful to maintain the normal operation of digital city life.

innovative case of blockchain-enabled digital city

Dubai's digital city project integrates a variety of new digital technologies such as blockchain, Internet of Things and artificial intelligence, and is committed to making Dubai "the happiest city in the world".

One of the major innovations in Dubai's digital city is to strive to realize the winding operation and management of all government data transactions in 221, and realize the electronization of 1 million paper processes every year. This digital reform of blockchain empowerment is expected to save $1.5 billion worth of process management costs, save 25 million hours of process processing time, and reduce 114 million tons of carbon emissions. In addition, the Dubai government is actively cooperating with many blockchain companies, focusing on key areas and landing a number of blockchain application cases.

The European Commission also recognized the importance of blockchain in the reform of government services, and established the European Blockchain Partnership in 218, covering local law enforcement agencies, governments and private enterprises in Europe. Members of the Digital Economy and Social Department of the European Commission are also full of confidence in the value of blockchain technology in the construction of digital cities, and indicate: "We believe that all public services in the future will be built on the infrastructure of blockchain."

For example, the government of South Tyrol, Italy, realized the electronization of citizens' data through blockchain technology. Residents only need to register their basic personal information once to enjoy the services provided by different government departments, streamline government affairs processing procedures, reduce costs and increase efficiency.

At the same time, based on blockchain technology, Estonia has built a national health information electronic system. Through this blockchain platform, doctors can conveniently inquire about patients' blood tests, recent treatments, X-ray examinations and other related data when authorized. Patients can also clearly query their own medical records, prescriptions issued by doctors and other information. The data on the blockchain is difficult to tamper with and can be traced all the way, which can guarantee the security and integrity of the data on the platform.

Wanxiang blockchain has also begun to actively explore the construction of blockchain-enabled digital cities, building a safe and credible digital base with blockchain integrating new digital technologies such as the Internet of Things and artificial intelligence, and managing production and life in a more refined and dynamic way through technologies such as privacy computing, knowledge mapping, digital twinning and distributed business incentives, thus forming an intelligent, low-carbon and flexible city with technology integration, comprehensive application and high-end development, and helping to build a prosperous and flexible economy.

Wanxiang Blockchain is committed to building a digital city that truly understands you. Through the trusted digital base built by the integration of blockchain and new technologies, every resident can have an exclusive digital avatar, truly master the data sovereignty, and enjoy a comfortable urban life without prying into privacy.
