Abstract

The invention discloses a block chain data processing method and device, equipment and a storage medium. The method can be executed by a blockchain node, and comprises the following steps: respondingto a blockchain branch request sent by a proof node in a blockchain network, the blockchain branch request being generated when the proof node detects that a current blockchain satisfies a branch condition; according to a chaining rule, performing child-mother chaining on the current block chain, and storing the chained mother chain in the proving node; and processing the data of each block in themother chain, constructing a provenance block of a sub-block chain according to a processing result, and taking the sub-block chain as a new current block chain. The data storage space of the block chain network can be reduced, so that the data synchronization and data query efficiency of each node is improved.

Description

technical field [0001] The embodiments of the present invention relate to data processing technology, and in particular to a method, device, device and storage medium for processing blockchain data. Background technique [0002] The blockchain network has the advantages of distributed decentralization, no trust system and no tampering, and has gradually become an urgently needed database technology in the financial industry. [0003] At present, in order to achieve the consistency of data stored by each node in the blockchain network, it is necessary to synchronize the stored data to each node of the blockchain network. However, with the continuous expansion of blockchain applications, the data stored in the blockchain network is also increasing sharply, occupying a large amount of storage space, resulting in long time-consuming and Problems such as low data query efficiency in the blockchain need to be improved urgently. Contents of the invention [0004] The embodiment...
