Blockchain Demo App

A SwiftUI iOS application that serves as a client interface for the Swift-Blockchain server implementation.

Overview

This iOS application provides a user-friendly interface to interact with a blockchain server built with Swift and the Vapor framework. The app allows users to:

• View the current state of the blockchain
• Mine new blocks
• Create and submit new transactions
• Manage blockchain nodes
• Visualize the blockchain data

Requirements

• iOS 15.0+ / macOS 12.0+
• Xcode 13.0+
• Swift 5.5+
• A running instance of the Swift-Blockchain server

Setup & Installation

1. Clone this repository and the Swift-Blockchain repository
2. Start the Swift-Blockchain server instance
3. Open Blockchain_demo.xcodeproj in Xcode
4. Configure the server URL in the app (default is http://localhost:8080)
5. Build and run the app on your device or simulator

Features

Blockchain View

The main view displays the current state of the blockchain, showing blocks, their hashes, and included transactions.

Mining View

Allows users to mine new blocks and see the mining process in real-time.

Transactions View

Interface for creating new transactions by specifying:

• Sender address
• Recipient address
• Amount

Nodes View

Manage consensus between different blockchain nodes:

• Register new nodes
• Resolve consensus issues by synchronizing with the longest valid chain

Connection to Swift-Blockchain Server

This app connects to the Swift-Blockchain backend server, which implements:

• Proof of Work algorithm
• Transaction validation
• Consensus mechanism for distributed nodes
• RESTful API for interaction

The app communicates with the server using the following endpoints:

• GET /chain - View the blockchain
• GET /mine - Mine a new block
• POST /transactions/new - Create a new transaction
• POST /nodes/register - Register new nodes
• GET /nodes/resolve - Resolve consensus issues
