Technological innovation has become an important engine for the development of the "two districts". The rapid promotion of new technology application scenarios
Beijing multi-field application of "Changan Chain" new technology
As the first driving force for Beijing's high-quality development, technological innovation is an important engine for the development of the "two districts".
Beijing has not only produced a large number of the latest scientific research results, but also the rapid promotion of new technology application scenarios, allowing the people to enjoy the scientific and technological innovation results.
In January of this year, Beijing released my country's first autonomous and controllable blockchain software and hardware technology system-"Chang'an Chain", which became one of the highlights of Beijing's high-standard promotion of the "two districts" construction.
A reporter from Beijing Youth Daily learned that the "Changan Chain" has outstanding characteristics such as traceability and non-tampering. It has been widely used in many fields such as the "Beijing Cold Chain" food traceability platform, Beijing electronic seal platform, and Haidian District government services. Help Beijing build an international science and technology innovation center.
Imported cold chain food: source can be traced and whereabouts can be found
Recently, the Haidian District Market Supervision and Administration Bureau has carried out several special inspections of imported cold chain foods.
In the Haidian Metro Supermarket, sales areas such as imported ice cream and cheese are posted with the exclusive QR code of "Beijing Cold Chain". Consumers can "scan" through WeChat to inquire about the quality and safety of imported cold chain food and product traceability information .
Scan the two-dimensional code, the basic information of these ice creams, entry cargo inspection and quarantine certificate, nucleic acid test report, disinfection information and other content are clear at a glance.
In order to implement the requirements for normalized prevention and control of the new crown pneumonia epidemic, since November last year, Beijing has begun to promote the application of the “Beijing Cold Chain” food traceability platform. Imported refrigerated and frozen meat, aquatic products and all storage temperatures are below 0°C (including 0°C). ℃) imported cold chain foods shall be retrospectively managed.
A reporter from the Beijing Youth Daily learned that the traceability platform was built by the Beijing Microchip Research Institute based on the "Changan Chain" technology to promote the digital smart economy and support the digital smart city with digital intelligent trusted traceability technology.
What is "Changan Chain"?
According to Guo Jingjing, a researcher at Beijing Microchip Research Institute, it is the first independent and controllable blockchain software and hardware integrated technology system in China, which plays the role of linking data elements.
Imported cold-chain foods have to go through multiple links such as circulation and warehousing from production and processing to supermarket sales.
The "Beijing Cold Chain" food traceability platform based on "Chang'an Chain" technology must scan the code to record the corresponding information and upload it to the chain during the circulation process.
In this way, if a certain batch of imported food is detected with the new coronavirus, the entire circulation link of the batch can be traced through the data on the chain, and the high-risk "closely connected" units and individuals can be quickly locked, from "chasing objects" to "Chasing people" to achieve a closed-loop system of epidemic prevention management to curb the risk of further spread of the epidemic.
According to the latest statistics, as of March 21, "Beijing Cold Chain" has recorded a total of 39,176 imported cold chain food products with 81,492 batches, involving 104 countries and all provincial administrative regions in China, with a total of 393,000 tons of products in circulation. .
Beijing electronic seal: the whole process data on the chain
Beijing electronic seal is also one of the application scenarios of "Changan Chain" technology.
On January 20 this year, the first set of electronic seals in Beijing began to be issued. Newly established enterprises can obtain a set of electronic seals for free while obtaining an electronic license, realizing the "three major pieces" of electronic business licenses, seals, and invoices. Full coverage.
A reporter from Beijing Youth Daily learned that there are 5 electronic seals in a set, including a legal name seal, a special invoice seal, a special financial seal, a special contract seal, and a legal representative name seal.
Electronic seals and physical seals have the same legal effect.
"The most important thing to use an electronic seal is to distinguish the authenticity and prevent forgery. This is the core value of the'Chang'an Chain'." said Yin Shu, a researcher at the Beijing Microchip Research Institute.
Electronic seals using the "Chang'an Chain" technology can upload the entire process data of seal making and issuing, signing and verifying seals, and construct a closed loop from seal application to use, so that the application information of the seal can be checked, controlled, and Retrospective.
According to statistics, on the first day of the issuance of electronic seals on January 20, 835 companies applied for a total of 4175 electronic seals.
The rapid popularization of the blockchain electronic seal platform represented by Beijing electronic seal will promote corporate legal persons to move more of the work of using seals to be completed online, while optimizing the business environment, and promoting the development of Beijing's digital economy. The whole society can be digitally upgraded.
Haidian government service: 87 scenarios online
In Haidian District, the "Changan Chain" technology has been implemented in 601 government service application scenarios, and the effect of "four reductions and one promotion" is remarkable, that is, it has realized "reduction of materials, reduction of time limit, reduction of links, reduction of running, and promotion of network" to varying degrees. do".
"I want to open a gallery" is the first theme scene in Haidian District with a large amount of software. After applying the "Chang'an Chain" technology, the whole process of online office is realized without running at a time.
Last year, Mr. Tang planned to open a gallery in Baishuiwa Village, Shangzhuang Town, Haidian District.
At that time, Haidian District took the lead in launching 5 scenarios on-chain applications including "I want to open a gallery".
Mr. Tang downloaded the "Haidian Tong" APP on his mobile phone, checked the specific work guide, and followed the prompts to complete the declaration of the "I want to open a gallery" event scene.
After receiving the application, the staff of the Bureau of Culture and Tourism of Haidian District will promptly examine and approve specific matters and contact Mr. Tang to confirm the method of obtaining evidence.
In the past, it took 6 working days to approve the opening of a gallery, but Mr. Tang completed the entire process in just 2 days.
Up to now, there have been 63 galleries bidding in Haidian District.
"Chang'an Chain + Teacher Qualification Certification" is the first scene application of "Chang'an Chain" technology in the education system of the city and even the whole country.
Through the "Changan Chain" technology to pull information such as ID cards, residence permits, and household registration books, the clerk can get the teacher qualification certificate at home with his fingertips, and realize the whole process of "no-face approval", changing from running multiple times to "one time" No need to run."
According to Chen Lei, Section Chief of the Science and Technology Information Division of the Haidian District Government Service Administration, during the centralized acceptance period for the "Haidian District Application for Kindergarten, Primary School, and Junior Middle School Teacher Qualifications" in 2020, a total of 1,220 applications will be processed, using the "Haidian Pass". The APP handled 622 cases.
According to statistics, through the application of "Chang'an Chain" technology, 141 online scenes in Haidian District reduced the submission of materials by more than 40% on average, 87 scenes realized the whole process of online office, and 57 scenes realized "only run once".
In the next step, the Haidian District Government Service Bureau will further expand the application scenarios and build a new ecosystem of Haidian government services with full chain, full scene and full time.
Promote the "Cross-province operation" work model based on "Chang'an Chain" technology with unique Haidian characteristics, and promote cross-regional handling of matters.
