The future of digital democracy isn't just about putting votes on a blockchain—it's about making that interaction as natural as having a conversation. Today, I want to share how I built a Web3 voting application that combines the transparency of blockchain with the intuitive power of AI using Gaia, a decentralized AI infrastructure.
The Vision: Democracy Should Be Conversational
Traditional blockchain interfaces can be intimidating. Users need to understand smart contracts, gas fees, and complex UIs just to cast a simple vote. What if instead, you could just say: "Create a vote about our next team lunch location with options: Pizza, Sushi, Mexican food, lasting for 1 day" and the AI would handle all the blockchain complexity?
That's exactly what this voting DApp does—it bridges the gap between complex blockchain operations and natural human conversation.
Why Gaia? Decentralized AI for Web3
Gaia isn't just another AI API—it's a decentralized computing infrastructure that lets you create, deploy, and scale AI agents. Here's why it was perfect for this project:
True Decentralization
Unlike centralized AI services, Gaia runs on distributed nodes, making it ideal for Web3 applications where decentralization matters. You can run your own node or use the network.
Tool-Calling Capabilities
Gaia's Llama-3-Groq-8B-Tool model excels at function calling, which is crucial for blockchain interactions. The AI can understand natural language commands and translate them into specific smart contract calls.
Blockchain-Native Design
Built with Web3 in mind, Gaia understands the unique requirements of blockchain applications—from handling wallet connections to managing transaction states.
Architecture: Where AI Meets Smart Contracts
The application follows a clean separation of concerns:
Frontend Layer
Built with Next.js and featuring a dual interface:
- AI Chat Interface: Natural language interaction with the voting system
- Manual Interface: Traditional web forms for users who prefer direct control
AI Integration Layer
The heart of the system is the AI route handler that processes natural language and translates it to blockchain actions:
// AI agent configuration
const openai = createOpenAI({
baseURL: GAIA_API_ENDPOINT,
apiKey: "" // Can be empty for local nodes
});
export async function POST(request: Request) {
const { messages } = await request.json();
const result = streamText({
model: openai(GAIA_MODEL),
system: systemPrompt,
messages,
maxSteps: 5,
tools, // Blockchain interaction tools
});
return result.toDataStreamResponse();
}
Blockchain Layer
Smart contracts deployed on Linea Sepolia using a factory pattern:
- VotingFactory: Creates new voting instances
- VotingBase: Individual voting contracts with options and time limits
Natural Language Commands That Work
The AI agent understands various natural language patterns:
Creating Votes
"Create voting 'What should our next project be?' options: Web App, Mobile App, AI Tool duration: 2"
Viewing Results
"Show all active votings"
"List votings"
"What's the current status of all votes?"
Casting Votes
"Vote for 0x1234...5678 option 2"
"I want to vote for the second option in the contract 0x..."
The AI handles the complexity of:
- Parsing natural language intent
- Validating contract addresses
- Managing transaction states
- Providing user feedback
Technical Deep Dive: AI Tools for Blockchain
The magic happens in the AI tools configuration. Here's how the system translates natural language into blockchain actions:
// Example tool for creating votes
{
name: "createVoting",
description: "Create a new voting with options and duration",
parameters: {
description: "string",
options: "array of strings",
durationType: "number (1=1hour, 2=1day, 3=1week)"
}
}
When a user says "create a vote about lunch," the AI:
- Parses the intent using the Llama-3-Groq-8B-Tool model
- Extracts parameters (description, options, duration)
- Calls the appropriate tool function
- Executes the blockchain transaction via wagmi/viem
- Provides natural language feedback to the user
Setting Up Your Own Gaia Node
One of the coolest aspects of this project is that you can run your own AI infrastructure. Here's how:
# Install GaiaNet node
curl -sSfL 'https://github.com/GaiaNet-AI/gaianet-node/releases/latest/download/install.sh' | bash
# Initialize with Llama-3-Groq-8B model (perfect for tool calling)
gaianet init --config https://raw.githubusercontent.com/GaiaNet-AI/node-configs/main/llama-3-groq-8b-tool/config.json
# Start your node
gaianet start
Now your voting DApp runs on completely decentralized infrastructure—no centralized AI service required!
Real-World Impact: Making Web3 Accessible
This project addresses a fundamental challenge in Web3 adoption: complexity barriers. By providing a conversational interface, we enable:
Non-Technical Users
People who find blockchain intimidating can participate naturally through conversation.
Rapid Prototyping
Teams can quickly create polls and votes without navigating complex interfaces.
Educational Value
Users learn about blockchain concepts through guided, conversational interactions.
Challenges Solved and Lessons Learned
State Management Complexity
Managing the relationship between AI conversation state, blockchain transaction state, and UI state required careful architecture. The solution was to keep each layer focused on its core responsibility.
Natural Language Ambiguity
Users don't always express intents clearly. The AI system includes validation and clarification flows to ensure accuracy.
Transaction Feedback
Blockchain transactions take time. The AI provides updates and manages user expectations throughout the process.
Performance and Scalability
The system performs remarkably well:
- AI Response Time: ~2-3 seconds for complex operations
- Blockchain Integration: Seamless transaction handling with proper error management
- User Experience: Natural conversation flow with real-time updates
Future Enhancements
The foundation is strong, and there are exciting possibilities ahead:
Knowledge Base Integration
Gaia supports knowledge bases that could include:
- Voting best practices and patterns
- Blockchain education materials
- Historical voting data and insights
- Governance framework documentation
Multi-Chain Support
Expanding beyond Linea to support multiple blockchain networks through the same conversational interface.
Advanced AI Capabilities
Implementing more sophisticated features like:
- Vote outcome prediction
- Participation analytics
- Automated governance suggestions
Open Source and Community
The entire project is open source and available for the community to build upon. Whether you're interested in:
- AI and natural language processing
- Blockchain development and smart contracts
- UX design for Web3 applications
- Decentralized infrastructure
There's something here for everyone to learn from and contribute to.

Conclusion: The Future is Conversational
This project represents more than just a voting application—it's a glimpse into a future where interacting with blockchain technology is as natural as having a conversation. By combining Gaia's decentralized AI infrastructure with thoughtful smart contract design, we're not just building applications; we're building the foundation for a more accessible, democratic Web3.
The intersection of AI and blockchain isn't coming—it's here. And with tools like Gaia making decentralized AI infrastructure accessible to developers, the possibilities are limitless.
