Problems solved by technology

However, levelDB is a non-relational database, so it cannot effectively handle the relational operations between complex data, that is, the reading speed and timeliness of the data cannot meet the growing demand of the distributed ledger scale of the blockchain.

Abstract

The invention relates to a block chain storage method and system based on a distributed index, and the method comprises the steps: determining the number of non-tampered minimum cells and a block generation interval according to a consensus protocol of a target block chain, and determining each forked verification period according to the number of non-tampered minimum cells and the block generation interval; in each round of bifurcation verification period, dynamically dividing a plurality of nodes on the block chain into a plurality of clusters based on a clustering algorithm, and establishing a routing index on each node in each cluster according to a Dijkstra algorithm; and enabling that each node in the target block chain reads or writes data in the block chain according to the routing index and the hash index of the node. According to the method, the updating time and the updating mode of the block chain storage index are determined through bifurcation generation and the clustering algorithm, and then the distributed indexes are established according to different roles of the nodes in the block chain, so that the read-write efficiency of the block chain and the timeliness of the indexes are improved.

Description

technical field [0001] The invention belongs to the technical field of blockchain storage, and in particular relates to a distributed index-based blockchain storage method and system. Background technique [0002] A blockchain is essentially a public distributed ledger shared by all participants in the system. In the blockchain network, there are thousands of nodes, and each node saves all the blocks and transaction data of the entire network. Once a node joins the network, it will continuously receive and verify blocks, consuming computing resources and storage resources. [0003] Research on the current status of blockchain development has proposed four bottlenecks in the current blockchain development, namely insufficient storage space, slow transaction processing, bandwidth limitations, and endless ledger issues. And these four bottlenecks are also understood as the performance of the CAP theorem in the blockchain, that is, it is impossible to find a way to solve the a...
