A method for sharing commodity transaction information based on block chain technology

Abstract

The invention discloses a commodity transaction information sharing method based on a block chain technology, and the method comprises the following steps: building an original block group, enabling anewly added user or information data to generate a new block, and enabling the new block and the original block to form a block chain; Writing an intelligent contract into the block chain, generatinga transaction instruction when two transaction parties initiate a transaction request, and storing new transaction data into a newly generated information intermediate storage block; In the whole flowing process of the commodity, commodity information and flowing information in each flowing step are stored in a newly generated information middle storage block; The two transaction parties initiatetransaction requests; According to the method, all participants on a commodity transaction chain can easily inquire all information of commodity transactions by setting a shared third party, so thatthe commodity transaction information is shared more fully, and meanwhile, through node classification and timestamps, all parties can inquire and supervise transaction data conveniently.

Description

technical field [0001] The invention relates to the field of block chains, in particular to a method for sharing commodity transaction information based on block chain technology. Background technique [0002] Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. In a narrow sense, a blockchain is a chained data structure that combines data blocks in a sequential manner in chronological order, and is a non-tamperable and unforgeable distributed ledger that is cryptographically guaranteed. In terms of blockchain technology, it uses block chain data structures to verify and store data, uses distributed node consensus algorithms to generate and update data, uses cryptography to ensure the security of data transmission and access, and uses automated script codes to A new distributed infrastructure and computing method that consists of smart contracts to program...

Problems solved by technology

[0006] (1) Most of the participants in the commodity trading chain are in the state of information islands, and it is difficult to interact with data, so information sharing is not sufficient, and it is easy for one party to tamper with transaction information, which is not conducive to the quality and authenticity of commodities;

[0007] (2) There are many steps in the flow of goods in the transaction process, and the information and data that need to be shared are also very cumbersome, so it is not conducive to the inquiry and supervision of all parties, and when there is a transaction problem, it is difficult to trace the source of the transaction, which is not conducive to accountability and problem solving
