Data uploading method and device for business data block chain

Abstract

The invention provides a data uploading method and device for a business data block chain and, relates to the technical field of block chains. The method comprises the following steps that: a block chain node determines a user operation to be linked, the business data block chain comprises a linked user operation, the business data block chain corresponds to a tree structure, and the tree structure is used for representing the logic of the linked user operation; wherein the tree structure comprises a state tree and a relationship tree; the user operation to be linked is verified based on the tree structure; and after the verification is passed, a block is generated based on a user operation to be linked, and the tree structure is updated based on the block. The user operation data is stored through the block, the tree structure stores the state of the user operation and the relationship between the states, and the user operation to be linked is verified based on the logic of the user operation recorded in the tree structure, so that the linking efficiency can be improved. The authenticity and effectiveness of the data are ensured, and the security of the data is improved.

Description

technical field [0001] The present invention relates to the technical field of block chains, in particular to a method and device for uploading data to a block chain of business data. Background technique [0002] At present, blockchain technology is a distributed storage ledger that uses technologies such as encryption algorithms and consensus mechanisms. With the application of blockchain technology, more and more Internet data will be stored on the blockchain. [0003] In the existing blockchain, only transaction data can be stored, and the transaction data includes the address of the transfer party, the address of the receiver, and the transfer amount; for various business data (such as: deposit data, traceability data, financial data, travel data, search data, self-media data, research data, advertising data, e-commerce data, community data, knowledge quiz data, knowledge payment data, shared bicycle data, recruitment data, life service data, rental data, voting data, ...
