Abstract

A block data segmentation storage method provided by the present invention includes: when a block chain node generates a new block, obtaining the transaction time interval corresponding to the current sub-ledger; judging whether there is a transaction in the transaction time interval of the current sub-ledger data; if yes, generate a common block and add the common block to the current sub-ledger; if not, judge whether the current system time is greater than the transaction time interval of the current sub-ledger; if so, generate the first block and add the first block The block is added to the newly created next sub-ledger, and the newly created next sub-ledger is set as the current sub-ledger; if not, no transaction data is returned. A continuous block chain storage account book is stored in segments according to time, which ensures the continuity and integrity of block data, and can also ensure relative independence, avoiding unlimited growth of block chain data, and improving block data management and query. The efficiency and convenience of operations such as , archiving, and node synchronization reduce the operating cost of the system.

Description

technical field [0001] The present invention relates to the technical field of data storage, in particular to a segmented storage method based on block data, a terminal and a medium. Background technique [0002] Blockchain is a decentralized distributed database technology that is participated by various nodes. The information recorded in the blockchain network adopts a block chain storage structure. Blocks are the data elements in the chain storage structure. The blockchain is connected to each other to form a one-way chain structure. The first block is called is the genesis block. Such a block chain structure is associated with each other through the hash value, which ensures the tamper-proof and traceability of the data. Each blockchain node will store complete record information of the blockchain system. With the operation of the system, the number of blocks and the number of transactions in the blockchain continue to increase, and there will be performance and effic...
