Recently, a change has occurred in the writing habit of Chen Hongchen, an internet writer: After completing the creation of a part of the manuscript, in addition to saving the content of the work, she also uploads the manuscript information to an invisible and intangible data link, adding to her intangible property A "lock". This "judicial blockchain" technology platform was built by the Hangzhou Internet Court.

"Xinhua Perspectives" reporters found that the blockchain technology that the public "often talks and always does not understand" has quietly landed in such scenes as judicial evidence, government administration, people's livelihood services, food traceability, and supply chain management. At the same time, bottlenecks such as difficulty in data interconnection, interoperability, and coordination are also prominent in popularization and application.

Writing, online shopping, invoicing … Blockchain technology is entering everyday life

The characteristics of "openness and transparency", "non-tamperable" and "non-deletable" make the blockchain technology show a broad application space in the fields of judicial certification and traceability of commodities.

"As long as the document is uploaded, the system will automatically generate a set of data: this password value, which is only 3KB in size and called the hash value, is the only electronic ID of the document. With this electronic ID, my work has With the certificate approved by the court, you will not be afraid of infringement disputes. "Chen Hongchen said.

Hangzhou citizen Mr. Huang just bought a can of imported milk powder recently. After receiving the goods, he found a small two-dimensional code on the milk powder can, and swiped the mobile phone to see all the logistics information of this can of milk powder from Australia to Hangzhou. It is understood that during the "Double Eleven" this year, through blockchain technology, Tmall platform has nearly 400 million Haitao products from more than 100 countries around the world, and has such an "identity card."

Recently, the reporter drove to the parking lot of Bao'an Sports Center in Shenzhen to experience the process of issuing electronic invoices on the blockchain: scan the QR code at the scene, enter the license plate and pay the parking fee with the mobile phone, and the WeChat public account of the parking system will automatically push the “invoice application Notice "entry. The reporter clicked to enter, entered the invoice header and tax number, and issued an electronic invoice with one click. The entire payment and invoicing process takes less than 2 minutes.

It is understood that at present, blockchain electronic invoices have been applied in some banks, supermarkets, subways, taxis, and airport buses in Shenzhen, involving more than 7,600 enterprises, with the number of invoices exceeding 10 million, and the amount of invoices exceeding 7 billion.

According to Tencent, the Tencent Cloud Blockchain Open Platform has been implemented in multiple scenarios in the past two years, including insurance direct compensation, fund settlement, electronic bills, supply chain finance, smart healthcare, and charity.

According to the "2018-2019 China Blockchain Development Annual Report" issued by the China Blockchain Ecological Alliance, blockchain technology is most actively used in the financial field, and has been formed in cross-border payments, asset management, and supply chain finance. A group of new products that can bear the actual business; have achieved staged results in the fields of electronic certificate and public welfare charity; began to explore in the fields of medical services, government management, transportation and logistics, but the products are not mature enough.

The "on-chain" effect is obvious in some areas, and some "pseudo-applications" cannot be ignored

The reporter's investigation found that in the financial and fiscal fields, the application of blockchain technology is conducive to reducing computing costs and enhancing asset credibility.

Taking electronic invoices as an example, Guo Jingli, chairman of Shengshi Foundation, which is responsible for the parking lot management and operation of Baoan Sports Center, said that multiple parking lots in Baoan Sports Center require about 100,000 invoices per month, and financial personnel need to manually count, distribute, and record Accounts, the workload is huge, and error-prone. Now, the workload is greatly reduced, reducing labor costs. "More importantly, blockchain electronic invoices allow our business data to be integrated 'on the chain' and become digital assets-when we negotiate operational cooperation, electronic invoice records are proof of business strength."

Cui Yan, a staff member of Shenzhen Taxation Administration and Technology Development Office, said that the blockchain electronic invoice realizes the entire process of invoice issuance, circulation, reimbursement and declaration on the chain, ensuring that the entire cycle of the invoice can be checked, verified and verified on the chain. It can be traced back, which solves the problems of over-voting, falsely reporting, and difficult to check the authenticity in the invoice circulation process.

In addition to the field of finance and economics, at present, the application of blockchain in the field of electronic certificate in China is developing rapidly, and the application effect in many related industries is obvious. Wang Jiangqiao, executive vice president of the Hangzhou Internet Court, said: "For example, the two parties signed a sales contract. Because the contract signing process, contract execution and other data are stored on the chain and there are multiple node witnesses on the judicial blockchain, after one party initiated the case, we It can be introduced into the Internet court through the platform, and the fact of breach can be clearly identified. "

According to data from the Hangzhou Internet Court, due to the clearer and simpler factual determination of the judicial blockchain platform, the rate of mediation and withdrawal of intellectual property disputes has exceeded 90%.

The reporter's investigation found that there are also some “pseudo-applications” in the promotion process of blockchain applications. For example, some of the so-called blockchain-based applications such as "blockchain chicken raising", "blockchain cultural relics identification", and so on. The data is only stored on the company's server, not synchronized to upstream and downstream, and can be tampered at any time. Solve trust issues.

Data interconnection is difficult, and large-scale applications need further technological breakthroughs

The reporter's investigation found that because the blockchain technology involves the interconnection and interoperability of multi-entity data, application landing and promotion need to coordinate multi-party institutions, and the construction and coordination of the blockchain platform is difficult.

"At present, the Internet courts in Hangzhou, Beijing, and Guangzhou have launched blockchain applications, but there are problems with platforms that are difficult to be compatible and case promotion difficult." A legal system practitioner said that at present, some blockchain platforms are based on associations and industries. The unit is on the chain, and the coverage of the application is relatively limited, which is only equivalent to "local area network" and not "Internet"; the blockchain technology standards provided by different companies are different, and there are difficulties in cross-chain connection.

The Shenzhen tax department also stated that the local blockchain electronic invoices and other electronic invoices from other places have not yet been recognized and communicated.

In addition, to support large-scale applications, the core technology of the blockchain needs further improvement and breakthroughs. Cai Liang, executive deputy director of the Blockchain Research Center of Zhejiang University, said that taking performance as an example, the general application scenario of blockchain has reached tens of thousands of transactions per second, but the current level of technology is still difficult to support large-scale, large-scale Applications. "It is critical to be able to break through bottlenecks such as networking that supports large-scale various networks, and software and hardware collaboration technologies."

Li Ming, director of the Blockchain Research Office of the Electronic Industry Standardization Institute of the Ministry of Industry and Information Technology, said that at present, blockchain applications are still in the early, niche, and trial operation stages, and there has not yet been a "killer" large-scale application. However, various industries are actively exploring and trying. With the implementation of 5G technology, the increase of market data volume and the improvement of technical problems, more application cases are expected to appear in the future.
