Welcome to an engaging exploration of the implementation of the Practical Byzantine Fault Tolerant (PBFT) Algorithm! In this guide, we will not only walk through the implementation steps but also highlight the beautifully crafted web interface that makes monitoring this system a breeze. So, let’s get started!

Understanding PBFT

The PBFT is a consensus algorithm that enables a network of nodes to reach a majority agreement, even when some nodes may behave maliciously or fail. Think of it as a group of friends at a dinner table deciding on a restaurant, where some might try to sway the decision for their own preferences. The goal is to ensure that a majority agrees on a restaurant despite disagreements.

Setting Up Your Environment

To begin implementing the PBFT algorithm with a web interface, follow these steps:

1. Clone the Project Repository

Open your terminal and run the following command:

bash
git clone --recursive https://github.com/luckydonald/pbft.git

Remember, the --recursive flag is crucial; it ensures the phppgadmin container is available.

2. Build Docker Containers

Ensure you have Docker installed on your machine, then build the containers with:

shell
docker-compose build

3. Start Services in Order

Because some services may take longer to start, it is best to follow this order:

1. Database and Database Browser:

shell
docker-compose up -d postgres postgres_browser

2. Start the API:

shell
docker-compose up -d api

3. Start the Web GUI:

shell
docker-compose up -d web

4. Scale the nodes (e.g., to 4 instances):
1. Older compose syntax:

shell
docker-compose scale node=4

2. Newer compose syntax:

shell
docker-compose up --scale node=4

5. Start the nodes:

shell
docker-compose up -d node

6. To stop and reset everything:

shell
docker-compose down

7. Remove unused containers:

shell
docker rmi $(docker images --filter dangling=true -q --no-trunc)

Accessing the Web GUI

Once everything is set up, you can access various interfaces through the following URLs:

Server	URL
API	http://localhost:80
Database	http://localhost:8080/phppgadmin
Web GUI	http://localhost:8000

Troubleshooting Tips

If you encounter any issues during the setup or while accessing the system, here are a few troubleshooting ideas:

• Ensure Docker is running correctly on your system.
• Check your network settings to confirm accessibility to localhost URLs.
• Review the terminal output for any errors during the Docker containers’ startup process.
• If you face persistent issues, look into the bug tracker to see if others have had similar problems.
• Feel free to explore the project repository for existing fixes or improvements.
