The document "Guiding Opinions on Deepening the Integration and Sharing of Public Resource Trading Platforms" (State Office Letter [2019] No. 41) points out the need to optimize services such as witnessing, venues, information, archives, and expert extraction.
However, at present, public resource transaction process witnessing is mainly based on manual on-site witnessing, which has limited witnessing intensity, high occupation of human resources, and limited witnessing effect.
Due to its centralized characteristics, the traditional digital witness system is prone to data tampering, and the data is easily damaged or lost during the storage and migration process, which has certain flaws in terms of security and usability.
Utilize the distributed, difficult to tamper, and traceable characteristics of the blockchain to solidify and store the data generated in each transaction link, and accurately record the time, content, and data source of the data through time stamp technology, summary algorithm, and electronic signature technology.
According to the technical characteristics of the blockchain, simple structured data can be directly saved on the blockchain. For unstructured layout files, videos, audio and other large files, the summary information and original files can be saved through the blockchain.
Save via a distributed file storage service.
When there are disputes or problems in a transaction, the blockchain can provide a set of credible transaction process data and clarify the responsibilities of all parties involved in the transaction.
Achieve the goals of risk prevention and control in all aspects, traceability of the entire process, and improvement of all-round services.
Promote the rationalization of electronic guarantee rates. Promote the financial services and corporate financing of bidding enterprises. Promote the rationalization of electronic guarantee rates. At present, electronic bidding deposit guarantee letters have certain applications in the field of bidding, solving the problem of capital occupation of bidding deposits for bidding enterprises.
However, because financial institutions currently do not have reliable historical bidding behavior data of bidders, they are unable to judge the default risks of different bidders. As a result, the guarantee services charged to bidders adopt fixed rates, which makes a small number of bids with high default risks
The cost of personal guarantee is allocated to most bidders with low default risk, which increases the guarantee rates for most bidders to a certain extent.
At present, it is up to the bidder to choose whether to use an electronic letter of guarantee, and the rate is the main basis for the bidder's choice. If the bidder's performance record is shared through the blockchain, the performance risks of different bidders can be analyzed, and different bidders can be provided with
Different guarantee rates not only reduce the risks of financial institutions, but also reduce the use costs of most bidders and promote the use of bid guarantees. To a certain extent, they can also encourage bidders to abide by their promises and maintain the order of the bidding market.
Facilitating Bidding Enterprise Financial Services The bidding behavior of bidders is dispersed in various trading centers. Simply aggregating data into a centralized information system has the risk of data tampering (untrustworthy), and valuable bidder transaction behavior data cannot be safe and reliable.
Gather together and enjoy everywhere.
Through blockchain technology, bidders from multiple trading centers are brought together, and historical bidding, winning bids, defaults, violations and other behavioral records provide data support for financial institutions to evaluate bidders' credit in subdivided industries.
Traditional corporate loans solve the financing problem of winning bidders mainly by assessing the company's solvency: there are requirements for collateral, audited statements, sustained profitability, etc. However, most small and medium-sized enterprises cannot provide these "proofs" at all, making financing difficult and
Expensiveness has become a problem faced by many small and medium-sized enterprises in bidding activities.
Using the methods of the past will no longer work. To solve the financing difficulties of small and medium-sized enterprises, we can only rely on new technologies and new tools.
With the help of the non-tamperable characteristics of blockchain, primary business data from multiple trading centers are gathered, and big data analysis technology is combined to build a portrait of a credible bidder.
On the one hand, it improves the risk control level of financial institutions and taps high-quality bidding companies. On the other hand, it lowers the loan threshold for bidding companies and optimizes the service experience.
Drawing on the supply chain finance model, the tenderer is a core enterprise with good credit in government departments and national enterprises and institutions. The winning contract obtained by the successful bidder as a supplier is considered by financial institutions to be a high-quality asset and applies for loans from financial institutions.
Under the traditional paper-based model, there is a risk of order and contract fraud and the process is cumbersome, and a centralized information system requires strong authority from the operator.
The distributed ledger and difficult-to-tamper characteristics of the blockchain will help solve the above problems. The contract signing between the tenderer and the bidder and the subsequent financial service links will be realized on the blockchain, which not only solves the problem of data credibility but also reduces the risk of corruption.
The entire system relies on a centralized authority.
