On the basis of the existing block chain technology, the embodiment of the invention is provided for shortening the time for inquiring the e-commerce data from the block chain, improving the efficiency for inquiring the e-commerce data from the block chain and improving the efficiency for inquiring the e-commerce data from the block chain.
The embodiment of the invention provides an e-commerce data query method and user equipment applied to a block chain, which are suitable for e-commerce scenes, such as the browsing times of commodities, the sales data of the commodities (such as the purchase data of the commodities and the return data of the commodities) and the like.
In the embodiment of the present invention, the data of the e-commerce, such as the data of the goods, may include the number of times each goods is browsed, the number of times each goods is purchased, the number of times each goods is returned, and the like. Then, when a user needs to obtain data of a certain product, the user obtains the data of the corresponding product from the database according to the attribute information (such as an identifier of the product) of the product through User Equipment (UE). Meanwhile, in order to ensure the safety of the commodity data, the user equipment calculates the hash value of the data of the obtained commodity, verifies the calculated hash value on the block chain, namely compares the calculated hash value with the hash value stored on the block chain, and determines that the data of the commodity obtained by the user equipment from the database is not tampered and is safe when the calculated hash value is consistent with the hash value stored on the block chain.
The following describes, with reference to a flowchart of a commodity data query method in fig. 1, an e-commerce data query method applied to a block chain according to an embodiment of the present invention.
As shown in fig. 1, the execution subject of the method is a user equipment, and the method comprises the following steps:
s101, the user equipment acquires data of the commodity from a database according to the attribute information of the commodity, wherein the data of the commodity in the database is acquired from the block chain.
In this embodiment, in order to shorten the time for the user equipment to query the data of the commodity from the blockchain and improve the efficiency for the user equipment to query the data of the commodity, the data of the commodity on the blockchain is downloaded, analyzed, and stored in a database, which may be a conventional database, for storing the data. The database may be embodied as a server, or other device for storing data.
When a user needs to inquire the data of a certain commodity, the data of the commodity corresponding to the commodity attribute information is inquired and obtained from the database according to the attribute information of the commodity through user equipment.
In one embodiment, the attribute information of the item may be an identification of the item, which is a unique identification. The attribute information of the product may be information such as a name of the product.
In one embodiment, the data for the item may be the number of times the item was viewed, sales data for the item, and the like. The sales data of the goods may include information such as the number of times the goods are purchased, the number of times the goods are returned, and the like.
For example, when the user needs to inquire the purchase times of the commodities with the commodity names A, the user inquires the purchase times of the commodities with the commodity names A through the user equipment, and in one embodiment, the user equipment sends an inquiry request to the database, wherein the inquiry request comprises the commodity names A and information of the purchase times of the commodities with the commodity names A needing to be inquired; and after receiving the query request, the database feeds back the data of the purchase times of the commodity name A to the user equipment.
And S102, the user equipment performs hash calculation according to the data of the commodity to obtain a first hash value.
When the user device receives data of a product, for example, when the user device receives data of the number of purchases with a product name of a, the user device performs a hash calculation on the data of the number of purchases with the product name of a to obtain a hash value, which is also referred to as a first hash value.
It should be noted that, in this embodiment of the present invention, "first" and "second" are used to distinguish information, such as hash values, but in this embodiment of the present invention, "first" and "second" are used only to distinguish things, and the information itself is not limited.
S103, the user equipment compares the first hash value with a second hash value stored on the block chain.
In order to ensure that the data of the commodity obtained from the database is consistent with the data of the commodity obtained from the blockchain, that is, to ensure that the data of the commodity in the database is not tampered, the data of the commodity obtained from the database needs to be compared with the data of the commodity stored in the blockchain.
When the commodity data is stored on the blockchain, a hash value obtained after conversion of the commodity data is stored, so that the user equipment calculates the data of the commodity obtained from the database to obtain the hash value (also called as a first hash value) of the commodity data, and then compares the hash value with a second hash value of the data of the commodity stored on the blockchain to determine that the data of the commodity obtained from the database is not falsified and is consistent with the data of the commodity on the blockchain, namely the data of the commodity obtained from the database is correct and safe.
In one embodiment, the comparing, by the user equipment, the first hash value with a second hash value stored on the blockchain includes: and the user equipment sends the first hash value to the block chain, and the first hash value is compared with the second hash value on the block chain.
In one embodiment, the comparing, by the user equipment, the first hash value with a second hash value stored on the blockchain includes:
and the user equipment acquires the second hash value from the block chain and then compares the first hash value with the second hash value. The specific process can be as follows: the user equipment sends an acquisition request to a certain node on the block chain to acquire a second hash value of the commodity data on the block chain; and when the user equipment acquires the second hash value of the commodity data from the block chain, comparing the first hash value with the second hash value.
And S104, when the first hash value is consistent with the second hash value, the user equipment determines that the data of the commodity acquired from the database according to the attribute information of the commodity is consistent with the data acquired from the block chain.
When the first hash value is consistent with the second hash value, the user equipment determines that the data of the commodity acquired from the database is safe, is not tampered and is consistent with the data of the commodity on the blockchain.
By adopting the method for querying data on the block chain provided by the embodiment of the invention, the data of the commodity on the block chain is analyzed into the database, and then the user equipment acquires the data of the commodity from the database as required, so that the time for acquiring the data of the commodity from the block chain by the user equipment is shortened, the efficiency for acquiring the data of the commodity by the user equipment is improved, and the user experience is improved.
