Transaction data storage method, tracing method and blockchain network

Abstract

The invention provides a transaction data storage method, a tracing method and a blockchain network. A blockchain in the blockchain network is of a double-chain storage structure and comprises a root chain and a transaction chain, each block and last block information of each block are stored in the root chain, and all transaction records of the same commodity arranged according to the commodity transaction time sequence are stored in the transaction chain; when the commodity transaction records are tracked and traced, the block information of the block in which the last transaction is located can be found according to the commodity id, and the corresponding block is found in the root chain according to the block information; and all transactions in the block are traversed to find the last transaction of the commodity, the last transaction is decomposed to obtain the block information of the last transaction of the commodity, and by parity of reasoning, all historical transaction records of the commodity are found, thereby achieving the purpose of tracking and tracing, and enabling tracing and positioning to be accurate.

Description

technical field [0001] The present invention relates to the field of block chains, and more specifically, to a transaction data storage method, a traceability method, and a block chain network. Background technique [0002] Different trading fields have extremely high requirements for traceability supervision, and related technology platforms are also constantly developing and improving. The reason why counterfeiters can succeed in counterfeiting is that supervision is difficult to cover, and that timely information traceability inspection is difficult. Blockchain technology provides an idea for solving the problem of information traceability inspection. Blockchain data is stored in blocks, and the storage of these data is mainly based on transactions. In other words, these data blocks are actually composed of a series of composed of transactions. [0003] The traditional way to trace the source of transactions is that the system traverses from the current block, judges wh...

Problems solved by technology

[0003] The traditional way to trace the source of transactions is that the system traverses from the current block, judges whether there is a target transaction in the block, and then searches the previous blocks in turn until the corresponding transaction is found, but this mode has low efficiency and high time cost. problem, it is difficult to rely solely on a storage structure such as the blockchain to meet query requirements

[0004] Therefore, in order to solve the problem of difficult positioning of data traceability, it is an urgent problem to propose a new blockchain chain storage structure
