Problems solved by technology

However, the storage space on the blockchain is extremely precious and limited, and the engineering orders of power companies involve massive amounts of unstructured data. The current blockchain nodes are sufficient to support high-capacity data streams. Blockchain nodes cause a huge computing burden, resulting in the inability to meet the needs of engineering order settlement

Abstract

The invention provides an engineering order settlement method and system based on block chain data storage, and the method comprises the steps: extracting structured data and unstructured data in an engineering order, and generating a block chain node for the engineering order; extracting feature data corresponding to the type of the non-structural data, and storing the feature data into a block chain node based on a link evidence storage mode; extracting an order object and an order type involved in the engineering order according to the structured data, generating a smart contract, and storing the smart contract and the structured data in a block chain node based on a content evidence storage mode; and when an engineering order settlement request is received, performing settlement of the engineering order according to the stored smart contract. The characteristics of decentralization and tampering incapability of the block chain technology are utilized, the defect that settlement records of different electric power companies are tampered at any time is overcome, the settlement risk is reduced, different data processing and uplink modes are adopted, and the storage space of unstructured data on the block chain is saved.

Description

technical field [0001] The invention belongs to the field of power transaction management, and in particular relates to a method and system for settlement of engineering orders based on block chain data storage. Background technique [0002] Traditional power companies often involve a large number of engineering orders in the process of project implementation, and need to review the paper documents of these engineering orders through layers of auditing departments to complete the settlement. Therefore, due to the engineering management process of different power companies and different work departments The difference in the settlement of engineering orders affects the settlement efficiency of engineering orders, and it is unavoidable that information is not shared and opaque, which makes it difficult to trace the source of engineering orders, and it is difficult to find the drawbacks of abnormal transactions in time. [0003] The blockchain is a decentralized database. The o...
