Problem Statement 6 – Better Finance for Everyone with Stellar

What problem does your project solve, and who does it serve?
Lumos solves the inefficiencies, biases, and lack of transparency in traditional grant distribution processes. Today, grant applications are often reviewed behind closed doors, with opaque criteria, manual filtering, favoritism, and long wait times.

Who It Serves: Lumos empowers individual builders, startups, researchers, and open-source contributors who seek fair, transparent, and decentralized access to funding — especially those without strong traditional network connections.

Real-World Use Case: Using Groq AI, spam and low-quality grant submissions are automatically filtered and ranked. The community then votes transparently on Base network, ensuring democratic decision-making without centralized control. Winners receive grant payouts instantly through Stellar, eliminating the need for complicated banking processes and global remittance issues.

• Why you chose this problem: The traditional system of grant funding has several inefficiencies, including lack of transparency, slow processing, and susceptibility to spam proposals. We identified an opportunity to innovate by creating a decentralized system that enhances the grant funding process, making it more transparent, efficient, and fair.
• Key challenges you addressed:

1. Spam Proposal Filtering: One of the core challenges was to effectively filter out spam proposals that clutter the system and undermine its integrity.
2. Proposal Ranking: We needed to develop a reliable and fair ranking mechanism to ensure that the best proposals receive the highest priority.
3. Decentralized Voting: Ensuring that the voting process is secure, transparent, and decentralized was another significant hurdle.
4. Stellar Wallet Integration: Integrating Stellar XLM tokens for grant funding posed its own challenges, particularly ensuring a seamless, secure transaction system.

• Any pivots, brainstorms, or breakthroughs during hacking: Groq AI and Llama 70B Model: Initially, ranking proposals using AI was a challenging task. However, by utilizing the Llama 70B model, we were able to filter and rank the proposals efficiently, achieving the desired results. Voting System Integration: The Base Voting System took time to integrate due to the complexities of decentralized governance. However, after experimenting with different networks, Base Sepolia Network emerged as the most suitable option for our needs.

• [✅] Groq: Our project, Lumos, perfectly aligns with the Groq track by leveraging Groq's powerful AI capabilities to automate proposal evaluation and ranking. We use Groq to filter out spammy or low-quality submissions and objectively assess each grant proposal based on relevance, impact, feasibility, and innovation. This intelligent ranking system ensures that only the most deserving projects reach the voting phase, creating a transparent, scalable, and efficient grant funding process. Groq's AI models help us maintain fairness, save community time, and enhance the overall quality of the decentralized grant platform.
• [✅] Base: Lumos leverages the Base network to power its decentralized and transparent voting mechanism. Grant proposals, after being filtered and ranked by Groq AI, enter a community-led voting phase entirely on-chain via Base Sepolia. Each participant’s vote is securely recorded on Base’s scalable Layer 2 infrastructure, ensuring immutability, low gas costs, and a fair, tamper-proof process. By using Base, Lumos empowers a global community to collectively decide which projects deserve funding without relying on centralized intermediaries. The fast finality and Ethereum-grade security of Base ensure that governance stays transparent, censorship-resistant, and highly participatory — fitting perfectly with Lumos' mission of democratizing grant funding.
• [✅] Stellar: Lumos uses the Stellar network to handle decentralized grant payouts, ensuring instant, transparent, and borderless fund transfers. After a proposal wins through the on-chain Base voting, Stellar is used to disburse the allocated grant amount directly into the recipient’s Stellar wallet in XLM tokens. Stellar’s low transaction fees, rapid settlement speeds, and global accessibility ensure that winners — no matter where they are — receive their grants fairly and quickly. By integrating Stellar, Lumos removes banking barriers, promotes financial inclusion, and ensures that funding remains open and borderless, aligned with the decentralized spirit of Web3. Additionally, Stellar’s compliance-friendly infrastructure provides a foundation for scaling real-world grant programs in a trusted and auditable manner.

Our hackathon journey with Lumos was an exciting challenge, from integrating Base Voting and Stellar Wallet to using Groq AI and Llama 70B for proposal ranking. Overcoming these technical hurdles led to the rewarding moment of funding our first proposal with XLM tokens. Big shoutouts to HackHazards, the hackathon organized by Namespace, for fostering collaboration, Stellar for seamless integration, Groq for advanced AI, and Base for powering our decentralized voting system!
