Problems solved by technology

However, the design of storing unstructured data on the off-chain application side is difficult to prevent the risk of data loss. Data loss may cause the business logic in the smart contract to fail to close the loop and prevent business risks.

Abstract

An unstructured data storage method and a block chain system can be applied to the technical field of block chains and the financial field, and the method comprises the steps: receiving an intelligent contract transaction initiated by an external application, and obtaining the intelligent contract transaction to obtain corresponding execution node information; when the current block chain node is an execution node, performing consensus selection with other block chain nodes in the block chain system to obtain an unstructured data management node and a plurality of unstructured data storage nodes in a current period, and obtaining a preset split backup strategy according to a consensus message; providing the split backup strategy and the unstructured data to an unstructured data management node for splitting or merging to generate data fragments and index information; generating a threshold encryption parameter according to the data fragment; transmitting the threshold encryption parameter and the data fragment to a corresponding unstructured data storage node for storage, and generating a transaction result according to a storage result fed back by the unstructured data storage node; and feeding back the transaction result to the external application.

Description

technical field [0001] The invention relates to the technical field of block chains, can be applied to the fields of finance and data storage, and especially refers to an unstructured data storage method and a block chain system. Background technique [0002] In recent years, with more and more blockchain implementation scenarios, the types of data that need to be uploaded to the chain are becoming more and more extensive, and the data on the blockchain continues to grow and cannot be tampered with. Higher requirements are put forward for the design of blockchain data storage. requirements. The traditional blockchain node storage design is to store structured data in the local database, and store unstructured data outside the chain. Generally, the data storage and management are completed by the blockchain application side. The blockchain is only in the structured The hash of unstructured data outside the chain is recorded in the data to ensure that the data outside the cha...
