Description
Technical Field
The invention relates to the technical field of bidding, in particular to a bidding purchasing method based on a block chain technology.
Background
Bidding is an international practice, is a product of high development of commodity economy, is a mode of preferential bargaining developed by organizations by applying the functions of a technical method, an economic method and a competitive mechanism of market economy. In the purchasing behavior of goods, engineering and services, the bidder attracts a plurality of bidders to perform equal competition according to the same conditions through the pre-published purchase and requirements, and experts in the aspects of technology, economy, law and the like are organized according to the specified procedures to perform comprehensive review on the plurality of bidders, so that the behavior process of the bidder who selects the project preferentially is selected. It is essential to obtain the best goods, projects and services at a lower price.
At present, the traditional bidding platform has the following problems: 1) the trust mechanism is lacked, and the benefits of the bidding and tendering parties cannot be guaranteed; 2) the bidding process is opaque, and dark box operation exists; 3) ensuring that the gold is not returned or the returning procedure is complicated; 4) the quality of the bidders is good and uneven.
The block chain technology is a billing technology which is commonly maintained by multiple parties, uses cryptography to ensure transmission and access safety, can realize consistent storage, is difficult to tamper and prevents repudiation, and is also called as a distributed ledger technology. In a blockchain system, all committed transactions are stored in the chain, which increases the length of the chain when a new transaction is confirmed, without modification of previous data, thereby ensuring data integrity.
The block chain technology is combined with a traditional bidding platform, the dark box operation in the bidding process can be reduced to a certain extent, however, the existing bidding platform based on the block chain technology only carries out data chaining aiming at a certain specific link in the bidding process, the whole process of bidding is not involved, the problem of partial link opaqueness does not exist, in addition, the quality problems of the guaranteed gold refund and the bidder are not involved, and the benefits of both sides of bidding can not be guaranteed.
Therefore, the technical staff in the field needs to solve the problem of how to provide a block chain-based bid method which is transparent in the whole process, guarantees the benefits of both bid and tenderer parties, and can return the deposit in time.
