Description
Technical Field
The invention relates to the technical field of block chains, in particular to a commodity transaction method, a system, equipment and a storage medium for a block chain intelligent contract.
Background
With rapid development of internet science and technology, internet-type commodity sales become more and more widespread, at present, internet-type commodity sales are mainly based on platforms, and a sales company or a product production party builds a network platform, needs to build a cloud server, and can support product platform sales by building the server. The statistical information of the product sale is too simple, the detailed list of the product sale and the consumer information are relatively independent, a large amount of manual statistics and order printing processes are needed for acquiring complete sale data, and all detailed conditions of the commodity sale cannot be monitored in real time. At present, network platform sales are mainly transaction models constructed by centralized thinking, the value of the transaction models is remarkable, namely authority is established, multi-party trust is obtained through authority endorsement, and simultaneously the reliable and safe data is ensured by depending on capital and technical strength behind the authority. Once the central platform has a BUG or is under attack, there is a great risk that all data is lost, and in addition, the central platform has the possibility that the data is tampered.
the Blockchain (Blockchain) is a novel application mode of computer technologies such as distributed data storage, point-to-point transmission, a consensus mechanism, an encryption algorithm and the like. The consensus mechanism is a mathematical algorithm for establishing trust and obtaining rights and interests among different nodes in the blockchain system. The blockchain is also a bottom-up innovation technology, is not directed at the reformation and the upgrade of a certain kind of application, but can generate subversive changes on all scenes related to data storage and information exchange processes, and the application prospect of the blockchain is expected by people.
The concept of smart contracts, proposed by nissabo in 1994, refers to contracts in which the terms are recorded in computer language instead of legal language, which defines in mathematical and programmed form a series of contracts' rights and obligations, which, once triggered by a particular transaction, can be automatically executed. Due to the lack of system and technical support at that time, the concept of intelligent contracts is not realized until the appearance of Etherns in 2013, so that the intelligent contracts can be executed in a trusted decentralized blockchain environment. The intelligent contract based on the block chain system not only has the advantages of cost efficiency and the like, but also can avoid the interference of malicious behaviors on the normal execution of the intelligent contract, has the characteristics of automation, decentralization and result determination, and cannot be stopped once being deployed on the block chain, so that the intelligent contract ensures that the processes of storage, reading, execution and the like are transparent, the record can be tracked and cannot be tampered.

Each tile user can purchase goods (products or services) as a buyer and provide goods (products or services) as a seller, and a certain tile user can be only a seller or a buyer; when point-to-point commodity transaction is directly carried out between any two block users, when the block users serve as sellers, the block users are called as supplier users, and commodities are provided; when the block user is a buyer, it is called an acquirer user.
(2) the on-line transaction relationship is confirmed to generate a transaction order by the point-to-point commodity transaction between the requiring party user and the providing party user:
the demander user initiates a commodity purchase request to the supplier user in a point-to-point mode, pays the confirmed cost (the confirmed cost can be a token equivalent to the sale price of a product of the supplier user or the confirmed cost after the supplier user and the demander user are further communicated) to the supplier user, receives the paid cost of the demander user, automatically establishes the online transaction relationship between the demander user and the supplier user, and generates a transaction order. In the embodiment of the invention, the supplier user pays the fee by paying the token, preferably, the token is a legal token, and the payment mode is bank transfer; note that the token is not limited to the embodiment of the present invention, and may be digital money (also referred to as virtual money).
(3) The supplier user and the demander user execute a block chain intelligent contract, before the demander user confirms that goods are received or confirms that the supplier user fulfills goods service, the supplier user initiates a freezing request of the transaction order trust guarantee by itself or the block chain system, and the freezing request is to freeze a plurality of certificates of the supplier user as the trust guarantee of the goods transaction;
The freezing request also comprises a freezing period, and a plurality of certificates which are used as trust guarantees of the commodity transaction are in a freezing state from the beginning to the end of the freezing period. The holders (i.e. the supplier users) of the plurality of certificates cannot handle the certificates in the frozen state, the handling includes transaction, presentation, extraction and the like, and the events handled by the certificates in the frozen state are all listed as invalid events by the block chain system.
(4) Once the acquirer user confirms the receipt of the goods or confirms that the supplier user is performing the goods service, the acquirer user initiates a unfreezing request of the transaction order trust guarantee by himself or the blockchain system. It should be noted that the service of confirming the goods receipt of the demander user or the goods fulfillment of the supplier user may actively confirm the goods receipt of the demander user or the goods fulfillment of the supplier user, or after a set period of threshold time, the blockchain system defaults that the demander user receives the goods or the supplier user fulfills the goods service, and the blockchain system automatically initiates a thawing request of the transaction order trust guarantee.
