The Chinese government has unveiled a Blockchain-based ID system as part of the country’s future smart cities. As reported by the Chinese daily tabloid newspaper Global Times, three partnering institutes in Shijiazhuang and the northern Hebei Province of China, are creating the system.

The institutions have therefore reached out to different cities around the globe, requesting them to submit their city identification codes so they could join the initiative.

According to Zhang Chao, who doubles as the Director of the Zhongguancun Industry and the lead developer of the project, the technology is entirely indigenous. Furthermore, he said that the blockchain-based ID system for smart cities would have a unified distribution rule, a resolution of distributed storage, and a tamper-resistant code.

Deploying Blockchain-Based ID System 

The new digital infrastructure allows cities to share data more efficiently securely and transparently. The technology will form the core of China’s push towards the creation of smart cities in the most populous country on earth. 

Besides, the Chinese government is pushing towards the digitization of its cities because of the continuing rural-urban migration. Nevertheless, a Smart city is a concept currently being piloted in a few localities in China. 

By implication, the baseline infrastructure in China like sanitation and hygiene, electricity, transportation system, environmental protection, and the health system are in dire need of repair. As a result, Smart cities could be the solution to the infrastructural decays. 

The idea of the creation of smart cities using the Blockchain-based ID system may be a noble one. However, there are fears of China’s propensity for surveillance. 

There are questions as to whether the country’s focus on Blockchain technology will come with dystopian consequences. QT will soon bring you an in-depth analysis of that.  

On the other hand, there has been a tremendous boom in China regarding Blockchain adoption. But the primary fear is that it may end up creating the type of society and system that the technology is against from the very beginning.

The Rise Of Smart Cities Across The Globe 

A smart city integrates and employs a variety of technologies for making municipal operations more efficient and effective. It comes with certain things such as renewable energy, self-driving cars, energy-efficient houses, and communication systems. 

In July this year, the UAE unveiled its Smart Dubai. The initiative aims to make Dubai the first city to be fully powered by Blockchain technology and AI by 2021.

The concept of smart cities is up-and-coming as they involve the deployment of a network of interactive sensors for efficiency. According to the International Data Corporation, smart city technology spending will grow to USD 135 billion by the year 2021. 

Currently, Google is creating a smart city in Toronto. Likewise, Limestone Network, a Singaporean startup, has also announced a new Blockchain-based smart city project in the Cambodian capital of Phnom Penh. 

The project is estimated to go live by early 2022. It will have partners like data analytic institutes, financial institutions, ride-hailing apps, among others. 

The Role Of Blockchain In Smart Cities

For any smart city to function effectively and efficiently, it will need a system that permits devices to monetize certain activities. This mechanism includes verifying and confirming the authenticity of significant transactions. 

That is where Blockchain technology comes in to play a vital role. Accordingly, the Blockchain system will serve as a payment centre for public transport such as trains, buses, as well as subway tickets. 

Meanwhile, the Island of Malta is already in partnership with Omnitude to develop a Blockchain infrastructure for public transport management. 


The unveiling of the Blockchain-based ID system for smart cities in China further reiterates that Blockchain application is ubiquitous. It shows that there is an exponential increase in the mainstream adoption of the technology.
