Answer

The consortium chain network environment includes a blockchain system that supports and maintains the blockchain. The system consists of multiple nodes that communicate with each other through a peer-to-peer network. Each node can perform operations such as storing account identifiers, creating and verifying blockchain transactions, creating and verifying blocks, and executing blockchain contracts. Devices can join the network and interact with nodes to participate in blockchain operations.

The console acts as a bridge between users and the blockchain. It receives user input, converts it into commands compatible with the blockchain, sends these commands to the blockchain network, and then converts any output received back into a form that can be understood by the user.

The main framework acts as the entry point for the console. It initializes and loads other components of the console, including the CLI, command manager, blockchain SDK, and tool manager.

The command manager interprets user input and determines relevant blockchain operations. It maintains a list of registered commands and generates blockchain-specific commands using appropriate command plugins, which are then sent to the blockchain SDK.

The transaction plugin manages commands related to blockchain transactions, such as adding a transaction or querying transaction information. The block plugin handles commands related to blocks, such as querying block information or block headers. The event plugin manages commands for subscribing to and receiving blockchain events.

The blockchain SDK provides a set of APIs to interact with the blockchain. It receives commands from the command manager, interacts with blockchain nodes, and returns any requested information.

The console adapts to different blockchains by replacing the existing blockchain SDK with a new SDK associated with the new blockchain. The new SDK follows the same protocol, allowing users to interact with different blockchains using the same command interface.

The tool manager provides functionality to support other console components. For example, it can calculate hashes, generate digital signatures, or verify blockchain transactions. When other components need these functions, they can call the tool manager.

Initializing the console involves starting the main framework, creating a CLI instance, loading and initializing the blockchain SDK, and registering the command manager and command plugins.

The user enters a query in the CLI, which is interpreted by the command manager. The command manager calls the block plugin, which generates a command for retrieving block information. The command is sent to the blockchain SDK, which interacts with the blockchain node to retrieve the requested information. Finally, the information is displayed to the user in the CLI.

Paper Title
