Welcome to the intriguing world of BandChain, a robust decentralized data delivery network. This article will guide you through the steps to set up BandChain, explore its modules, and troubleshoot any issues that may arise. Let’s get started!

Understanding BandChain Modules

Before diving into the setup, it’s essential to familiarize yourself with the various modules available in BandChain. Think of these modules as different departments in a company, each with its own responsibilities and expertise:

• Chain: The core reference implementation of the BandChain blockchain.
• Bridges: Lightweight client bridges connecting to other smart contract platforms.
• Lambda: AWS Lambda package to execute data source programs.
• Go-Owasm: A Go library to execute oracle scripts using Wasmer.
• Helpers: Client-side utilities for enhanced functionality.
• OBI: Implements Oracle Binary Encoding.
• Owasm: A library for writing WebAssembly oracle scripts.
• Scan: A web interface to explore the Decentralized Data Delivery Network (D3N).

Running BandChain with Docker

To bring BandChain to life, you’ll use Docker, a tool that simplifies application deployment. Here are two methods for running BandChain:

1. Run on 4 Validators

• Navigate to the directory: chaindocker-config
• Execute the command: generate-genesis.sh
• Run the command: docker-compose up multi-validator

2. Run 1 Validator (for Development)

• Navigate to the directory: chaindocker-config
• Execute the command: generate-genesis.sh
• Run the command: docker-compose up single-validator

Optional: Run Owasm Studio

If you want to interactively work with your setup, you can run Owasm Studio using the command:

docker-compose up single or multi owasm-studio

Tear Down

To bring down your setup, simply run the command:

docker-compose down -v

Becoming a Validator

If you’re interested in stability and credibility in the BandChain network, consider becoming a validator. Check out this Guide to Becoming a Validator for more information.

Troubleshooting Tips

While setting up BandChain, you might encounter some issues along the way. Here are a few common problems and their solutions:

• Docker Issues: Ensure that Docker is properly installed and running. Use docker ps to check if your containers are active.
• Script Errors: If you get errors when running generate-genesis scripts, verify that your paths are correct and the scripts have execution permissions.
• Connection Problems: If unable to connect to the network, ensure your firewall or security settings are not blocking Docker’s network.
