Problems solved by technology

However, since the world state tree is mostly composed of Merkle bucket trees, which have the disadvantage of high computational cost, frequent hash calculations for Merkle bucket trees will greatly affect the processing performance of the blockchain system. At the same time, it will bring serious data write amplification phenomenon.

Abstract

The invention discloses a method and device for storing world state slices based on incremental buckets. The method slices the block data on the chain into several generations according to the generation division method. The method mainly includes generation management, data storage and data query Three parts; the generation management part is mainly responsible for the setting of the generation and the change of the generation, the distribution of the generation number and the effect of physical separation of the data; the data storage part is mainly responsible for the incremental storage of the data in the generation and the real-time update of the world state; the data query part It is mainly responsible for the data query between the current generation and the historical generation. Using the independent Bloom filter in the generation can achieve the purpose of fast data retrieval. The present invention can effectively disperse the storage pressure through the incremental storage method, and can also enrich the hot data into a newer generation, while reducing the data retrieval pressure, and improving the query efficiency of the hot data.

Description

technical field [0001] The invention belongs to the field of computer systems, relates to block chain technology, and in particular to a world state slice storage method and device based on incremental buckets. Background technique [0002] Blockchain technology, also known as distributed ledger technology, the blockchain system can safely store data, and the stored information cannot be forged and tampered with. The transaction confirmation on the blockchain is shared by all nodes on the blockchain. Complete, and its consistency is guaranteed by the consensus algorithm. [0003] The world state is the sum of the state information generated by the blockchain system based on the account model after the transaction is executed, including the status information of all accounts and smart contracts on the blockchain. Thus, almost all transaction requests will change the current world state. The world state generated after the transaction execution of each block is the execution...
