Problems solved by technology

[0005] In the existing reputation evaluation schemes, the data source is usually the user evaluation of the third-party platform. However, these user evaluations stored in the database of the third-party platform are easy to be tampered with, which will affect the accuracy of subsequent reputation evaluation.

specific Embodiment approach

[0043] Such as figure 1 As shown, it is a specific implementation of a transaction data chain storage method for reputation evaluation disclosed by the present invention, including:

[0044] S101. Establish a shipping transaction data chain. The shipping transaction data chain includes a plurality of sequentially linked shipping transaction data blocks. Each shipping transaction data block corresponds to a shipping transaction. Each shipping transaction data block includes a block header, transaction data storage Unit and block tail, the block header includes the storage location information of the shipping transaction data block and the transaction related party information; the transaction data storage unit includes a plurality of transaction link subunits, and the data of the transaction link subunits can only be written Once written, it will be solidified and stored without modification; the block tail is defined by the transaction data storage unit in the shipping transac...

Embodiment 2

[0065] This embodiment is a specific implementation of a transaction data block chain storage method for reputation evaluation disclosed in the present invention. The transaction data block chain storage method for reputation evaluation uses multiple nodes that communicate with each other For data storage, the transaction data block chain storage method for credit evaluation includes:

[0066] After any node obtains the data writing request of the target transaction link subunit, it sends the data writing request of the target transaction link subunit to all other nodes, and all nodes follow the method for reputation evaluation described in claim 1. Transaction data chain storage method for data writing.

[0067] In order to facilitate the sharing and utilization of data, in the present invention, data can be stored in the form of blockchain. Complete data storage is performed in each node, and each node stores data independently based on transaction information, and each nod...

Abstract

The invention discloses a transaction data chain type storage method and a block chain storage method for credit evaluation. Each transaction data storage unit comprises a plurality of transaction link subunits corresponding to different transaction links, and each transaction link subunit can only input data and cannot modify the data, so that the data cannot be modified once being recorded, andthe authenticity of the data is ensured. Furthermore, the information of different transactions is stored in blocks; the data content of the previous block and the storage position of the next block are encrypted to serve as an independent block tail to be stored in the previous block; under the condition that the encryption algorithm is not leaked, the content of the block tail is not tampered, the authenticity of the data is easy to verify, the difficulty of data tampering is further increased, and the security of data storage is improved.

Description

technical field [0001] The invention relates to the fields of shipping and data storage, in particular to a chain storage method and a blockchain storage method for transaction data used for reputation evaluation. Background technique [0002] Credibility refers to the degree of compliance and trustworthiness of transactions reflected from social reputation, economic conditions, and performance of commodity transactions. With the gradual development of the commodity economy, the trading activities of goods and services are becoming more and more frequent, and the credibility of the two parties is becoming more and more important to each other. Reputation evaluation is to evaluate the transaction participants based on the historical records in past transactions. [0003] Ship shipping refers to the logistics transportation mode of transporting goods by waterway. Compared with air and land transportation, ship shipping can transport a larger amount of goods per voyage, makin...
