Cracking the "Wonderful Proof" Problem

How to prove "your mother is your mother"? Four years ago, at an executive meeting of the State Council, the Prime Minister mentioned this case.

He said that he saw media reports that some citizens wanted to travel abroad and needed to fill in the name of an emergency contact, so he wrote his mother's name. As a result, the relevant departments asked the citizen to provide materials to prove that "your mother is your mother".

"How can this be proven? It's a big joke!" he said.

This case shows from the side how difficult it is for ordinary people to do things.

The superficial appearance of the strange certificate is that some local government agencies have a weak sense of service; the underlying reason is that some local government agencies have difficulties in obtaining evidence when issuing certificates and are unwilling to take responsibility.

Take the "circular proof" that is the most troublesome for the masses as an example-the masses want to issue A proof, they must first have B proof; and if they want to issue B proof, they must first have A proof. The essence of this type of problem is that the data between units A and B cannot communicate, and neither party wants to take responsibility without evidence.

In this regard, the solution for government agencies is to open up data and allow data to flow between multiple departments.

But blindly opening up data has also brought new problems: who has the right to enter, modify, and query data? Who should protect the data privacy of citizens?

In addition, the traceability of the operation of the blockchain ensures the authenticity of platform data and the inviolability of citizens' personal privacy.

According to the Central Government Network, in 2017, Chancheng District, Foshan City, Guangdong Province launched the "Intelligent City" plan, and Chancheng District became the first county in China to explore the application of blockchain in government affairs.

The core of this plan is the IMI identity authentication platform based on blockchain technology. "IMI", which means "I am I".

At present, this system is connected to the District Civil Affairs Bureau, Local Taxation Bureau, Social Security Fund Management Bureau and other departments, and citizens can complete the issuance of notarized information by themselves on the platform.

Chancheng IMI Identity Authentication Platform

Specifically, on the IMI identity authentication platform, after the information of natural persons and legal persons is encrypted, it will be automatically uploaded to the chain to realize distributed storage. After obtaining the authorization of the parties, each node in the platform can query data and issue certificates.

Today, residents of Chancheng can easily handle affairs through mobile APPs.

At the beginning of this year, "Nanfang Daily" reported that the Chancheng IMI identity authentication platform promoted the open sharing of more than 7 million pieces of data from 24 departments and 299 data sets, covering road traffic, science education, health and people's livelihood. 14 themes such as service.

Extensive landing

In fact, blockchain + smart cities have already blossomed everywhere in China.

In Nanjing, the National Development and Reform Commission, the Public Security Bureau, the Human Resources and Social Security Bureau, and the Transportation Bureau jointly launched the mobile app "My Nanjing". Inside, you can pay living expenses, deal with traffic violations, and inquire about personal provident funds.

"My Nanjing" has a built-in blockchain electronic license sharing platform. When the user submits the application form online, the system will automatically verify the information of his or her electronic certificate, without the need for the user to come to the door.

In addition, "My Nanjing" also has a built-in "financial supermarket" - Nanjing Blockchain Inclusive Finance Platform. This platform connects government data with financial institutions through blockchain technology, realizing the credible flow of data and allowing financial companies to better issue credit loans to individuals and businesses.

According to public information, as of September this year, the personal credit loans issued by the platform have reached 11.7 billion yuan. On this platform, from application to payment, users spend less than 10 minutes, and the bank's labor cost per 100 million loans has also saved 340 people/day.

In Shanghai, the Yangpu District Government is exploring the application of blockchain in the application of the Internet of Things, and obtains safe, efficient and non-tamperable data through blockchain + Internet of Things to make decisions for urban public management.

In Hunan, in November 2018, the Loudi Land and Resources Bureau issued the country's first real estate blockchain electronic certificate, realizing the on-chain real estate information. It not only marks the geographic location information of the real estate, but also additionally indicates the blockchain address of the certificate.

In Xiong'an New District, blockchain technology has been applied to many fields such as rental platforms, government bidding, and personal point management.

Among them, the Xiongan blockchain fund management platform has realized the transparent management of financing, capital control, and salary payment for multiple construction projects. It can not only supervise the capital flow of urban construction projects, but also realize the automatic allocation of wages and project funds to avoid arrears.

In Guangdong, in August 2018, Shenzhen issued the country's first blockchain electronic invoice, realizing the storage, circulation, and reimbursement of invoice information on the chain. The tourist attractions in Lijiang and the medical institutions in Zhejiang have also realized electronic bills on the chain.

Recently, Shenzhen also issued the country's first traffic fine blockchain electronic bill, realizing the whole chain of traffic fine information.

In terms of smart city construction, local governments, as city governors, play an important role, but non-governmental forces cannot be ignored.

For example, the judicial blockchain unified platform led by the Supreme Law is based on the Ant Blockchain of Ant Financial. The blockchain platform in the Nanjing Smart City project was built by Nanjing local companies Rongze Technology and Zhongxiang Jinlian.

On the other hand, civil power, as an important part of the urban organism, is also promoting the further implementation of blockchain smart cities.

This summer, Professor Qi Yong from Nanjing University of Science and Technology led a student team to introduce blockchain technology in multiple parking lots near Nanjing University of Science and Technology, realizing the shared management of parking spaces and alleviating parking difficulties.

There are also listed companies trying to introduce blockchain technology into electric vehicle charging management, using blockchain to realize the transfer of power resources and funds, and to improve the utilization rate of charging piles in cities.

Difficulties in the future

After the collective study meeting of the Political Bureau of the Central Committee on October 24, the blockchain + smart city has once again attracted the attention of local governments.

"After the leader's speech, the company received a significant increase in cooperation intentions from local governments." The person in charge of a blockchain technology company told a blockchain.

But he also said that local governments also have some concerns about the construction of blockchain smart cities.

These local governments are paying attention to whether the central government will provide a unified solution for the implementation of blockchain smart cities in some areas. Because if the local government builds its own platform prematurely, it may cause a waste of local fiscal budget.

For example, in the judicial field, in August this year, it was reported that the Supreme People's Court is building its own unified blockchain platform.

At the beginning of November, according to ChainDD, the Supreme Court has stopped local courts from building their own blockchain systems—the completed platforms are allowed to continue to be used; while all newly-built platforms are suspended until they are connected to the Supreme Court. Unified blockchain platform.

In the local government system, the public security, law, and taxation systems are more independent than the administrative system, and it is more likely to establish a provincial and national unified blockchain platform.

And these areas are precisely the first areas where the blockchain is implemented in smart cities.

In other words, the best way is for the central government to formulate a unified standard, and each local government invites bids, purchases, and connects to the system according to the relevant standards.

Taking the provident fund system as an example, Chen Chun, academician of the Chinese Academy of Engineering and chairman of Qulian Company, said in an interview with the media that the Ministry of Housing and Urban-Rural Development has now built a unified blockchain platform to upload the data of 491 cities across the country to the convenience of residents. Use provident funds across regions.

According to a bidding document released by the China Government Procurement Network, in June 2019, the Wuhan Housing Provident Fund Management Center completed the bidding and procurement of the blockchain data platform project of the Ministry of Housing and Urban-Rural Development.

The document shows that the blockchain data system of the Ministry of Housing and Urban-Rural Development includes two platforms: an access platform and an interactive platform, and the platform includes modules such as data collection, transmission, verification, chaining, encryption and decryption, and query.
