Method and system for reverse pricing of buyer based on block chain

Abstract

The invention relates to the field of reverse pricing of a buyer, and provides a method and a system for reverse pricing of a buyer based on a block chain. The method comprises the following steps: receiving a buyer element by a first client, generating a buyer contract according to the buyer element, and recording the buyer contract in a block chain, the buyer element comprising a first element and a buyer price, and the first element comprising a to-be-purchased commodity name; receiving a seller element by at least one second client, generating a seller contract according to the seller element, and recording the seller contract in the block chain, the seller element comprising a second element, a seller price, and the second element comprising a to-be-sold commodity name; and judging whether the seller contract read from the block chain conforms to the buyer contract or not by a server, if yes, generating an intelligent contract for concluding a transaction, and recording the intelligent contract in the block chain, and if not, notifying the first client and the second client of a message characterizing the transaction failure. The invention avoids the control right of a centralized system management platform to the transaction between the buyer and the seller.

Description

technical field [0001] The present invention relates to the field of buyer's reverse pricing, in particular to a blockchain-based buyer's reverse pricing method and system. Background technique [0002] At present, with the development of the economy, the supply of social material goods and services is becoming more and more abundant, and the phenomenon of oversupply in many industries has become increasingly prominent. The excess of material goods and services has gradually become an inevitable trend of the development of the times, and the phenomenon of vacant resources has become increasingly prominent.

Problems solved by technology

Therefore, the centralized management platform of this buyer's reverse pricing system cannot provide the public with an open and transparent platform commission algorithm, which puts both buyers and sellers in a disadvantageous position. The gap between the rich and the poor in society is not conducive to building an open and transparent social wealth mechanism

[0008] In addition, the centralized system management platform plays the roles of price calculation, price display, transaction matching, payment guarantee, etc. during the transaction process. This method has the defect of relying on the platform, and the transaction amount cannot be settled in real time.

To a certain extent, increased transaction costs and risks

[0009] On the other hand, if the centralized system management platform is attacked or the platform operator commits fraud, the transaction between buyers and sellers is very insecure
