Bulk commodity spot transaction system based on blockchain smart contract

Abstract

The invention relates to the technical field of block chains, in particular to a bulk commodity spot transaction system based on a block chain smart contract. A method comprises the following steps: initiating a user account registration request; creating an account, and completing digitization of user account information; initiating a cargo information creation request, and creating cargo data; according to the cargo data, initiating a cargo transaction process, and after the cargo transaction process is completed, outputting the cargo transaction data through an API in the blockchain platform; the data layer receiving the cargo transaction data, performing persistence processing and encryption processing on the cargo transaction data, and pushing the encrypted cargo transaction data to the blockchain bottom layer through the blockchain API; and the blockchain bottom layer receiving the encrypted cargo transaction data, performing distributed accounting to write the cargo transactiondata into the block, and returning the transaction ID to the data layer for storage. According to the invention, the problem that the goods transaction data is tampered is avoided, and a guarantee isprovided for the authenticity of spot goods transaction information.

Description

technical field [0001] The present invention relates to the technical field of block chains, in particular to a bulk commodity spot trading system based on block chain smart contracts. Background technique [0002] Blockchain is a new application mode of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. With the development of blockchain technology, its application is becoming more and more extensive. [0003] In the existing bulk commodity industry, spot transactions are mostly conducted through offline transactions and spot trading platforms. In the process of offline transactions, most of the transactions are conducted through acquaintances, and only rely on offline contracts for constraints. The transaction data is easy to falsify and it is difficult to pursue responsibility, which can easily cause heavy losses; However, most of the centralized databases are independently operated and have ...

Problems solved by technology

In the process of offline transactions, most of the transactions are conducted through acquaintances, and only rely on offline contracts for constraints. The transaction data is easy to falsify and it is difficult to pursue responsibility, which can easily cause heavy losses; However, most of the centralized databases are independently operated and have no third-party supervision. Service providers can easily tamper with transaction data and are easily affected by external forces, such as fire in the computer room, damage to data hard drives, etc. Once the data is destroyed, It is impossible to recover, and it is easy to cause heavy losses to the enterprise.
