AI-Powered Accountability Platform that puts your money where your goals are.

Lock SOL to your deadline. AI validates your proof. Complete it? Get paid. Fail? Your money goes to winners.

Built with Solana, Snowflake Cortex AI, and Cloudflare for the OSU Hackathon 2025.

89% of people fail to achieve their goals. Why? No real stakes.

Traditional goal-tracking apps are free, so there's no consequence for giving up. Your broken promises cost you nothing.

DeadlineDAO introduces financial accountability through blockchain and AI-powered validation:

1. Stake SOL on your goal with a deadline
2. Submit proof when you complete it (text + image)
3. AI validates your proof instantly using Snowflake Cortex
4. Get paid if approved - your stake + share of failed goals' stakes
5. Lose stake if you fail - redistributed to winners

Real stakes. Real accountability. Real results.

Multi-layered AI validation using Snowflake's Cortex API:

5-Layer Validation Pipeline:

1. Text Analysis - Claude 3.5 Sonnet analyzes if proof matches goal
2. Sentiment Analysis - Detects emotional manipulation and fake enthusiasm
3. Fraud Detection - Mistral Large identifies generic/copy-pasted content
4. Specificity Check - Requires concrete details and verifiable information
5. Quality Scoring - Weighted algorithm combines all factors

Auto-decisioning:

• ✅ Approved (quality ≥75, confidence ≥70) → Instant payout
• ❌ Rejected (fraud detected, low quality) → Stake forfeited
• ⏸️ Needs Review (edge cases) → Manual review

AI Models Used:

• Claude 3.5 Sonnet (complex reasoning, text analysis)
• Mistral Large (fraud detection, specificity checks)

Fair economic model:

Your Payout = Your Stake + (Your Stake / Total Winners Stake) × Total Losers Stake

Example:

• You stake 0.5 SOL on "Learn TypeScript"
• 5 others stake 2.5 SOL total on similar goals
• 3 complete (including you), 2 fail
• You get: 0.5 SOL + (0.5/1.5) × 1.0 = 0.83 SOL (+66% profit!)

• Direct browser-to-R2 uploads via presigned URLs
• 10MB image limit with validation
• Automatic cleanup of old/orphaned files
• CDN-backed public access

Real-time dashboards tracking:

• Platform statistics (total goals, completion rates, stakes)
• AI validation metrics (approval rates, confidence scores)
• User performance (success rate, earnings, ROI)
• Leaderboard (top earners)

• RLS Enabled: Supabase Row Level Security for data protection

Phase 1: MVP ✅ (Current - Hackathon)

• Core functionality: goals, proofs, validation, payouts
• Snowflake AI integration
• Basic analytics

Phase 2: Enhanced Features

• Frontend UI (currently backend-only)
• Wallet integration (Phantom, Solflare)
• Real-time notifications
• Social features (share goals)

Phase 3: Advanced AI

• Historical proof analysis
• Success prediction
• Personalized recommendations
• Difficulty-based stake suggestions

Phase 4: Mainnet & Scale

• Solana mainnet deployment
