Abstract

Embodiments of the present application disclose an information storage method and apparatus for a block chain. A specific embodiment of the method includes buffering transaction information to be stored to generate a buffer block chain; reading a target cache block and a first cache block in the cache block chain in response to determining that a generation time of a target cache block in the cache block chain is within a preset time range, wherein the first cache block is a cache block in the cache block chain located after the target cache block; in response to determining that the revocation information of the target transaction information is present in the first cache block, writing the transaction information other than the target transaction information in the target cache block tothe memory block chain. This embodiment can avoid the excessive growth of the transaction information stored in the database that stores the block chain.

Description

technical field [0001] The embodiment of the present application relates to the field of computer technology, in particular to an information storage method and device for blockchain. Background technique [0002] A blockchain can essentially be a distributed computing and storage system. A blockchain usually has multiple nodes. Different nodes reach a consensus through certain calculation rules, and store the consensus transaction information in the database in the form of blocks. Multiple blocks form a blockchain. [0003] In general, in order to ensure the credibility of the blockchain, the database of the blockchain needs to record all the transaction information written into the block, so that the blockchain can replay the stored transaction information when the new node is synchronized and audited. data. But this method will cause the transaction information stored in the blockchain database to grow too fast. Contents of the invention [0004] The embodiment of th...
