SpaceDAO - The Decentralized Space Force

http://sdao.me

Overview

SpaceDAO is a decentralized autonomous organization (DAO) built on blockchain technology that enables collaborative funding and governance of space exploration missions. Users can propose missions, invest in mission shares, vote on governance proposals, and earn returns from successful missions.

Key Features

• Decentralized Mission Funding: Crowdfund space exploration missions through tokenized shares (ERC-1155)
• DAO Governance: Vote on proposals with $SPACE tokens to guide the future of SpaceDAO
• Mission Shares: Acquire ownership in missions as NFTs with revenue-sharing capabilities
• Escrow Payments: Mission funds are secured in escrow and released based on milestone completion
• Transparent Governance: All proposals, votes, and treasury movements are publicly visible on-chain

Tech Stack

Frontend

• React.js with TypeScript
• Vite for fast development and build optimization
• TanStack Query (React Query) for data fetching and caching
• Wouter for lightweight routing
• Ethers.js for blockchain interactions
• Tailwind CSS + shadcn/ui for styling
• React Hook Form + Zod for form validation

Backend

• Node.js with Express for API endpoints
• In-memory storage (simulated database) for demo purposes
• Drizzle ORM with PostgreSQL schema definitions (ready for database implementation)

Blockchain

• Ethereum/Polygon compatible (currently in mock mode for demo)
• Smart Contracts (Solidity) - ERC-20 for governance token, ERC-1155 for mission shares
• OpenZeppelin Governor contract pattern for DAO governance

Local Development Setup

Prerequisites

• Node.js 20.x or higher
• npm 9.x or higher

Installation

1. Clone the repository

git clone https://github.com/yourusername/spacedao.git
cd spacedao

2. Install dependencies

npm install

3. Start the development server

npm run dev

4. Open your browser at http://localhost:5000

Production Setup

Unix/Linux/Mac

Option 1: npm script

npm run build
npm start

Option 2: Shell script

npm run build
chmod +x ./start-unix.sh  # Make executable (first time only)
./start-unix.sh

Windows

We've provided several options for Windows users:

Option 1: Command Prompt

npm run build
start-windows.bat

Option 2: PowerShell

npm run build
.\start-windows.ps1

Option 3: Node.js

npm run build
node start-windows.js

How It Works

Data Flow

1. Users connect their wallet to the application
2. They can view active missions, governance proposals, and NFT shares
3. Using their $SPACE tokens, they can vote on governance proposals
4. They can invest in missions to receive tokenized shares (NFTs)
5. As missions reach milestones and generate revenue, holders receive proportional returns

Wallet Connection

The application interfaces with Web3 wallets like MetaMask through Ethers.js. In the demo mode, a mock wallet is implemented to showcase functionality without requiring an actual blockchain connection.

Mission Funding Process

1. A mission proposal is submitted through the DAO governance
2. DAO members vote on the proposal with their $SPACE tokens
3. If approved, the mission opens for funding with a target amount and deadline
4. Investors receive tokenized shares (ERC-1155) in proportion to their investment
5. Funds are held in escrow and released based on achieved milestones
6. Upon mission completion, any revenue is distributed to shareholders

Governance Model

• Proposals require a minimum of 10,000 $SPACE tokens to submit
• Voting period lasts 7 days
• A quorum of 30% of total $SPACE supply is required for execution
• Voting power is proportional to $SPACE token holdings

Future Enhancements

• Integration with real blockchain networks (Ethereum/Polygon)
• Implement milestone verification through Chainlink oracles
• Add multi-signature wallet for treasury management
• Develop mobile application
• Integrate with real space industry partners for mission execution

Deployment

The application can be deployed on any Node.js hosting service:

1. Build the application

npm run build

2. Start the production server

npm start

Environment Variables

Create a .env file in the root directory with the following variables:

# Server
PORT=5000
NODE_ENV=development

# For production with a real database
# DATABASE_URL=postgresql://username:password@localhost:5432/spacedao

# Smart contract addresses (for production)
# SPACE_TOKEN_ADDRESS=0x...
# MISSION_SHARES_ADDRESS=0x...
# DAO_GOVERNANCE_ADDRESS=0x...
