Since the publication of bitcoin: a peer-to-peer e-cash system in mid-2008, the underlying blockchain technology adopted by bitcoin has developed for more than ten years.

Therefore, when it comes to blockchain, it must be related to virtual currency. But in fact, blockchain is not equivalent to “virtual currency” or “digital currency”. As an emerging technology, blockchain itself does not create wealth, but it has great potential in new smart cities and other fields because of its advantages such as decentralization, non tampering, leaving traces in the whole process and traceability.

As we all know, “smart city” is a systematic project that uses various new technologies and concepts to optimize urban management and services, and blockchain is gradually becoming an important element in building a smart city and is increasingly included in the upgrade path of smart city. Aaron Wagener, co-founder of MXC, said, “smart city is no longer a buzzword, but a practical solution based on the Internet of things and blockchain”.

On November 8, 2019, the Chinese Academy of information and communications released the white paper on blockchain enabled new smart city (hereinafter referred to as the “white paper”). The white paper points out that the development of smart city is based on informatization and digitization. Blockchain has great potential in three aspects: infrastructure, data resources and intelligent application.

Industry experts believe that the important factor to measure whether blockchain technology can play a real social value is to have a lot of grounding gas and change people’s lives. Generally speaking, the current application scenarios of blockchain technology in the construction of new smart cities can be divided into four categories: first, data security and privacy protection, such as the protection of personal health and medical data, and the protection of tenants’ privacy information; Second, data tracing, such as electronic invoice, real estate transaction data management, etc; Third, data storage and authentication, such as personal identity authentication, electronic license storage and so on; Fourth, low-cost and reliable data transactions, such as open sharing of personal, enterprise and government data.

It is worth mentioning that in 2019, many regions in China successively used blockchain technology to develop smart cities: in January, Fuzhou, Fujian Province, cooperated with bitland to jointly build Fuzhou’s “urban brain” by using blockchain technology; In February, Yangpu District of Shanghai cooperated with the Berlin Polar Internet of things foundation, and the Macao science development fund signed a contract with Weizhong bank. The cooperation includes the use of blockchain technology to help the development of smart cities; In March, Hangzhou Metro and Alipay launched electronic invoice based on blockchain technology; In November, the xiong’an New Area blockchain innovation and development seminar was held. At the meeting, Zhang Qiang, the information officer of xiong’an new area, announced that the construction fund blockchain system of xiong’an new area was officially put into trial operation. A few days later, Quanzhou realized the synchronous issuance of paper licenses and electronic licenses of blockchain.

Conclusion: the pace of life in the metropolis will not fall for a minute, and the introduction and implementation of new technologies will take a certain time. In Gartner’s 2019 information officer agenda survey, 60% of information officers expect that the adoption of blockchain technology will reach a certain level in the next three years. Therefore, it may take several years for blockchain to deeply integrate and interact with Internet of things, artificial intelligence and big data projects, and then it can be widely used to manage urban services and public infrastructure.
