Abstract
The invention discloses a configuration control method for a block chain Hyperridge fabric, and relates to the field of block chain operation and maintenance. Aiming at the defects in the prior art, the invention provides a method for acquiring and modifying fabric configuration based on fabric, which can greatly improve the efficiency of block chaining and maintenance and the accuracy and convenience of configuration modification.
Description
Technical Field
The invention relates to a hyper-bridge fabric block chain allocation/control method
Background
With the increasing popularity of blockchains (alliance chains), many enterprises use blockchain technology to reshape transaction records during transactions and even to relocate transaction systems on the blockchain. And establishing a credible transaction environment by virtue of the characteristics of the block chain. Among many blockchain platforms, superridge fabric (hereinafter referred to as fabric) is an open source alliance blockchain underlying platform dominated by a plurality of international large-scale software companies such as IBM. There are two most basic components in the fabric, peer and orderer, where peer is responsible for running intelligent contracts, storing and querying blockchain data. orderer is responsible for consensus. All functions of a blockchain network are controlled by configs stored on the blockchain, including but not limited to admission control, permission checking, consensus patterns, etc. The current fabric is also in fast iteration. And fabric1.4 has become a long-term support for use as a production environment. However, the definition of the config of fabric is complicated, and it is time-consuming and error-prone to modify the config. The fabric provides a tool configxlator for converting configuration information in protobuf format of the fabric into data in json format (and vice versa). The user may manually modify this json data and then use the tool to reverse convert into protobuf format configuration data. And calculates the modified difference using configxlator, and finally submits to orderer using user signature so that the configuration can take effect. This is not efficient for the blockchain operation and maintenance personnel to modify the blockchain operational configuration, and the process of modifying the configuration is also highly error prone. The current blockchain configuration cannot be obtained quickly and efficiently. Great inconvenience is brought to block chaining operation and maintenance.
Disclosure of Invention
Aiming at the defects in the prior art, the invention provides a method for acquiring and modifying fabric configuration based on fabric sdk, which can greatly improve the efficiency of block chaining and maintenance and the convenience of the accuracy of configuration modification.
The data structure of the Fabric's configuration is defined using protobuf
A ConfigGroup is similar to a node of a multi-way tree, and each node may contain attributes (values) of the node, and the node may also have children. All configurations of the fabric are recorded on top of this tree structured data structure. We focus on the definition of the ConfigValue in the inner part
The value of ConfigValue is mainly where value is recorded in this field, but the type of value is bytes, i.e. the definition of value is not fixed, and different values have different formats. All subsequent us need to formulate one data structure for each value.
We now turn to sdk of fabric, which we use here fabric java sdk as an example. The fabric sdk provides a means by which fabric networks and nodes can be accessed. Through the fabric sdk, we can submit the transaction of the intelligent contract call, query, to the fabric network. The current fabric config may also be obtained or modified via fabric sdk.

Detailed Description
1. We obtain the corresponding fabric config after submitting the config fetch instruction to orderer via the fabric sdk. The config data is in protobuf format. At this time, we can decode the config data by configxlator proto _ decode to change it into json format data.
We currently already have the fabric config data in json format. The data is roughly as follows:
2. after the json format data is obtained, a specific value can be found through a specific path in a json node traversal mode. For example, we can locate the configuration of anchor peers of Org1MSP in fabric network by json path _ group. After finding this configuration, we can modify this value to the value we specify as needed. For example, port of the first anchor peer is modified to 10751. In order to operate all the fabric's config values easily, we will define a data structure for all the fabric's specific format, including but not limited to fabric identifier, fabric crypto config, fabric nodes, fabric msp config, anchor peers, etc. Thus, we can get and modify each specific config value quickly.
3. According to the requirement of the fabric, each time the configuration is modified, the corresponding version of the configuration needs to be updated, and then, here, the version of the anchor peer can be automatically added by one to meet the requirement of the fabric.
When the configuration modification is successful, we convert it back into protobuf format. And causes configxlator to calculate the modified difference.
4. The configuration modification difference data is signed by the user and then sent to the orderer via the fabric sdk, and then the new configuration item is validated.
According to the technical scheme, the implementation of the invention provides a method for acquiring, modifying and submitting the config value of fabric in a fully-automatic manner. The possibility of making mistakes in the modification of the fabric config configuration can be greatly reduced, which causes problems in the operation of the fabric network. Meanwhile, an effective tool for improving the efficiency is provided for operation and maintenance.
The above description is only for the preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
