Analysis on the Application of Blockchain Technology

Today, we will talk about the application analysis of blockchain technology in the field of public resource trading.

The transaction of public resources includes the purchase of public resources by public departments, such as government procurement, construction project bidding, etc. It also includes the sale of public resources by the public sector, such as bidding, auction, transfer of mining rights, sale of state-owned forest rights, disposal of state-owned financial assets and other public interests, public security and other public resources. The transaction of public resources is related to the national economy and people's livelihood, and involves the fundamental interests of the people. Therefore, the transaction management of public resources has always been an important management function of government affairs management in China.

In recent years, the National Information Center has continued to promote the construction of a public resource trading service platform, giving play to the role of comprehensive technical support for trading services, open access to data, and cross-regional transactions. The integration of public resources trading platforms based on digital technology has achieved remarkable results. Among them, blockchain technology has the characteristics of consistent data storage, not easy to tamper with and traceability, which provides a new idea and solution for solving the trust problem of public resource transaction data.

Information data management in the field of public resources transaction

Objectively speaking, the long-standing lack of credit in the field of public resources trading in China not only disrupts the normal market trading order, affects the fairness and justice of market competition, but also poses a serious risk threat to the quality of engineering construction and construction safety production. The reason is that the root of credit risk lies in the information asymmetry between the main bodies of the public resource transaction market, and in the limitations and defects of the traditional public resource transaction management in information data security and information data use.

Data security management issues

All kinds of transaction information and credit information in the field of public resources transaction contain great value. Under the trend of increasingly electronic management and service of public resources transactions in China, all kinds of information security risks, including user identity information of electronic bidding, information of potential bidders, information of bid evaluation committee, information of bidding documents, information of judges' bid evaluation, and information of bid evaluation results, have increasingly become an important issue affecting the efficiency, quality and fairness of public resources transactions.

Traditional data security technology can't effectively avoid all kinds of information data leakage, tampering, loss and other security management problems, especially under some technical means, it is difficult to trace the related data operations, which brings great trouble to data security management.

Data * * * Enjoy the application problem

The long-standing problems of various types of credit loss and dishonesty in the public resource trading market are mainly due to the limitations of relevant credit information of market entities in the application of * * *.

On the one hand, a large number of credit information of market entities has been deposited in various departments for a long time and has not been fully tapped;

On the other hand, the main credit information of public resources trading market involves many administrative departments, such as banks, public security, courts, housing and construction, human society, taxation and so on. The long-standing phenomenon of "data island" and "data Kirishima" between different administrative departments has hindered the efficient application of credit information in the public resource trading market.

Blockchain and public resource transaction information data management

According to the White Paper on the Development of Blockchain Technology and Application in China issued by the Ministry of Industry and Information Technology, in a broad sense, blockchain technology is a brand-new distributed infrastructure and computing paradigm. It uses blockchain data structure to verify and store data, uses distributed nodes to generate and update data, uses cryptography to ensure the security of data transmission and access, and uses intelligent contracts composed of automated script codes to program and manipulate data.

In essence, blockchain technology is a technical scheme to collectively maintain reliable databases through decentralization and high trust. In general, blockchain technology can be regarded as a bookkeeping method that supports the participation of the whole people.

Traditional data bookkeeping involves multiple bookkeeping entities and generates multiple data books. Under this accounting method, due to the lack of supervision, technical security and physical security, account data may be tampered with and lost, and related operations are difficult to trace. Therefore, it is difficult to guarantee the objectivity, fairness and security of account data.

Blockchain technology provides a technical scheme to support multiple accounting entities to participate in accounting. When any accounting entity modifies the account book, its modification behavior will form indelible marks (time stamps) in the account book records, and its modification results will be transmitted to all accounting entities' account books simultaneously, which can not only prevent the risk of tampering and loss of account book data, but also trace the relevant accounting behaviors and promote supervision.

In view of the above-mentioned information data management and credit problems in the field of public resource transactions, blockchain technology can effectively deal with and solve them through its own advantages and characteristics such as decentralization, distributed data storage, traceability, tamper resistance, openness and transparency.

Anti-tampering of transaction data of public resources

The public resource trading platform stores a large number of public resource trading data. In the traditional centralized data storage management, once data and backup are damaged or lost, it is difficult to recover, and there is a risk of data tampering due to loopholes in the supervision mechanism.

Blockchain technology adopts "decentralization" and "distributed data storage". The data damage or loss of one or more data storage nodes will not affect the data security of other data storage nodes. At the same time, the update of data account records is synchronous and open, which supports operation. Blockchain data will not be tampered with or destroyed unless all nodes are destroyed.

Establish a credible public resource transaction data environment.

Information asymmetry in the public resource trading market leads to adverse selection and moral hazard of market subjects, which affects the efficiency and quality of public resource trading and the orderly operation and development of public resource trading market.

Blockchain technology solves the problems of authenticity, security and openness of public resource transaction data, promotes the efficient application of credit information in public resource transaction market, promotes the establishment of trusted data environment for public resource transaction, prevents and evades various credit risks, and provides trusted data decision support for market transaction subjects and regulatory subjects.
