Welcome to the world of blockchain! This guide aims to walk you through a simple implementation of the blockchain concept and show you how to set it up effectively. With a user-friendly design, this project is aimed at demystifying blockchain technology.
Design Concept
The project consists of two main components: the agent and the interface.
Agent
An agent represents one peer in the blockchain network. Think of it as a diligent librarian in a library who ensures that all books (blocks) are not only properly stored but also shared with other librarians (agents) in the library (network). Each agent is connected to every other agent, creating a peer-to-peer (P2P) distributed network.
- Agents can send messages to each other to broadcast newly mined blocks.
- They can receive messages to collect blocks mined by other agents.
- Agents mine, validate, and grow their blockchain independently.
- Each agent syncs the latest blockchain with its peers.
The mining algorithm lays at the heart of any blockchain. In this project, we use the SHA256 hash to simulate this mining procedure.
Interface
The user interface utilizes Spring Boot, which may give an impression of being centralized. However, it’s crucial to understand that agents are capable of running independently as well. The interface is RESTful and returns data in JSON format. Additionally, a single-page application is provided to illustrate the blockchain concept visually.
Quick Start
Start Server
To get the server running, navigate to the project root directory and execute:
$ gradle bootRunUse Web Interface
Open http://localhost:8080 in your browser to access the web interface. You can perform the following basic actions:
- Add an agent to the network.
- Delete an agent from the network.
- Mine a new block and broadcast it to the network.
A color scheme distinguishes the blocks created by different agents.
Use REST Interface
You can also interact with the server using command-line tools like curl. Here are some commands to create agents and manage blocks:
Create New Agent
curl -X POST http://localhost:8080/agent?name=A1&port=1001curl -X POST http://localhost:8080/agent?name=A2&port=1002curl -X POST http://localhost:8080/agent?name=A3&port=1003Mine Block
curl -X POST http://localhost:8080/agent/mine?agent=A1Show Agents and Blocks
curl http://localhost:8080/agent?name=A1Remove Agent
curl -X DELETE http://localhost:8080/agent/allTroubleshooting
If you encounter issues while setting up or running the project, here are some troubleshooting suggestions:
- Ensure that your server is running properly and is reachable at http://localhost:8080.
- Check for any typos in your curl commands; a misplaced character can lead to HTTP errors.
- Ensure that the ports you specify when adding agents are not already in use by another application.
