[0106] Based on the first embodiment of the method for accessing blockchain data of the present invention, the method for accessing blockchain data further includes:

[0107] Step S40, the first acquisition module acquires the performance information of each blockchain node;

[0108] Step S50, the migration module migrates the blockchain application module to a blockchain node with small storage space and high performance, and migrates the blockchain storage module to a blockchain node with large storage space.

[0109] In order to enable better operation and maintenance of the blockchain management system, the blockchain storage module in this embodiment adopts distributed storage. Specifically, due to the fact that the business layer has higher requirements on the CPU and memory of the node where it is located, the data layer has higher requirements on storage capacity and I / O performance, that is, the blockchain application module has higher requirements on the CPU and memo...

[0126] Based on the third embodiment of the access method of blockchain data in the present invention, the access method may also include:

[0127] Step S70, the second acquiring module acquires current time information;

[0128] Step S80, the backup module performs data backup between the primary blockchain storage module and the backup blockchain storage module when the current time information matches the preset backup time.

[0129] In this embodiment, scheduled backup can also be supported. Specifically, the backup time can be preset according to time dimensions such as hours, days, or months, and the blockchain management system can obtain current time information and compare the current time with the preset backup time. When matching, data backup is performed between the primary blockchain storage module and the standby blockchain storage module. Specifically, in order to ensure the accuracy of backup data, the minimum granularity of data backup is a complete block, an...

Abstract

The invention discloses an access method for block chain data and a block chain management system. The method is applied to the block chain management system. The block chain management system comprises a plurality of block chain nodes, wherein each block chain node at least comprises a block chain application module, a block chain access module and / or a block chain storage module. The method comprises the following steps that: a block chain application module sends a data access request to a block chain access module; the block chain access module sends the access request to a block chain storage module according to configuration information; and the block chain storage module processes the access request, and feeds back data processed according to the request to the block chain application module through the block chain access module. Through adoption of the access method, existing block chain data are isolated into separate modules according to functions; the modules can be arranged in different nodes; and cross-network access is supported. Moreover, monitoring can be performed specific to each module; upgrade, repair and the like specific to a single module are supported; and operation and maintenance can be carried out more easily.

Description

technical field [0001] The invention relates to the technical field of block chains in the financial industry, in particular to a method for accessing block chain data and a block chain management system. Background technique [0002] Existing blockchain data is distributed by nodes, and each node stores full or partial blockchain data. When there are multiple nodes in the blockchain, each node saves an independent piece of data, and the data is stored on the physical hard disk of the node. This storage structure is simple and cannot provide cross-network access; at the same time, the existing blockchain software The modules in the blockchain are tightly coupled and deployed on the same node. When an operation error occurs, it is impossible to monitor a single module, and it is impossible to deal with the module that has an operation error, which leads to difficulties in the operation and maintenance of the blockchain. . Contents of the invention [0003] The main purpos...
