This readme provides an overview of the Iroha 2 blockchain explorer backend and instructions on how to install, run, and utilize the explorer's backend features.

Demo

Check out the Hyperledger Iroha 2 Blockchain Explorer Demo video here.

Installation

To set up the Iroha 2 blockchain explorer backend, follow these steps:

1. Install Rust 1.70.0

2. For full functionality of the explorer backend, build Iroha v2.0.0-pre-rc.9 and ensure it is running. You can find the build instructions for Iroha here.

3. Build the explorer backend binary:

cargo build --release

4. To prepare the Iroha client configuration, you have two options:

   Option 1: Define the client configuration manually.

   To configure Iroha client, refer to Configuration Reference or Iroha documentation.

   Option 2: Copy the configuration file from explorer-deploy-dev-tool.

Running the Backend

To run the Iroha 2 blockchain explorer backend, you have two options:

Option 1: Execute the following command in your terminal:

./target/release/iroha2_explorer_web \
  -c /path/to/client_config.json \
  -p 8080  # may be env PORT, default is 4000

Option 2: Alternatively, you can use the cargo run command with additional options. This command will display the help information, including the available options and their descriptions.

cargo run -- -h

Here is a breakdown of the options you can use:

• -c, --client-config <CLIENT_CONFIG>: Specifies the path to the iroha_client JSON configuration file. The default path is set to client_config.json if not provided explicitly.

• -h, --help: Prints the help information, which provides an overview of the available options.

• -p, --port <PORT>: Allows you to specify the port number on which the server will listen. You can set the port by providing the value after the flag, for example, -p 8080. If you don't provide this flag, the default 4000 port will be used. Additionally, you can set the PORT environment variable to specify the port.

• -V, --version: Prints the version information of the Iroha 2 Explorer Backend.

Feel free to adjust the command and options according to your specific setup and requirements.
