DeCleanup Network - Stellar Implementation Analysis

Project Overview

DeCleanup Network is a blockchain-powered environmental stewardship platform that incentivizes real-world cleanup efforts through tokenized rewards and verifiable achievements. The system creates a gamified experience where users can submit proof of their environmental cleanup activities and receive rewards in the form of tokens ($DCU) and DeCleanup Impact Products (dynamic NFTs, evolving with every cleanup)

Core System Architecture

The DeCleanup system consists of several interconnected components:

1. DCU Token System ($DCU)

• Purpose: Native reward token for cleanup activities
• Pre-TGE Phase: Non-transferable internal accounting system
• Post-TGE Phase: Full ERC-20 compatible transferable token
• Key Features:
  • Reward distribution based on verified cleanup submissions
  • Balance tracking and retrieval
  • Event emission for indexing and leaderboard systems
  • Controlled minting with authorization mechanisms

2. DeCleanup Impact Products (dIP)

• Purpose: Achievement NFTs representing cleanup milestones
• Characteristics:
  • ERC-721 based
  • Level-based progression system (Level 1, 2, 3, etc. until 10)
  • Metadata structure for impact verification
  • Upgrade mechanisms for progression through levels
  • Anti-fraud measures to prevent unauthorized minting

3. Proof of Impact (PoI) System

• Purpose: Verification mechanism for cleanup submissions
• Components:
  • Submission approval workflow
  • Claim verification logic
  • Evidence validation (photos, location data, etc.)
  • Reward calculation based on verified impact

4. Reward Distribution Engine

• Purpose: Automated reward calculation and distribution
• Features:
  • Multi-tiered reward structure
  • Future-proofed claim system with upgradeability
  • Integration with indexing systems for leaderboards
  • Event tracking for comprehensive analytics

Key Technical Challenges

Security Issues Addressed:

1. Input Validation: Ensuring all user inputs are properly sanitized
2. Authorization Controls: Preventing unauthorized DCU minting and dIP creation
3. Self-Call Vulnerabilities: Protecting against contract manipulation
4. Reward Sequence Issues: Maintaining proper order of operations

Optimization Concerns:

1. Gas Efficiency: Storage layout optimization and loop efficiency
2. Upgradeable Architecture: Future-proof contract design patterns
3. Error Handling: Standardized error messages across contracts

Functionality Requirements:

1. Multi-Contract Architecture: Separation of concerns across different contracts
2. Event Integration: Comprehensive event emission for external indexing
3. Testing Coverage: Robust unit testing and deployment procedures
4. CI/CD Integration: Automated testing validation on pull requests

Stellar-Specific Implementation Considerations

Advantages of Stellar for DeCleanup:

1. Low Transaction Costs: Ideal for frequent small reward distributions
2. Built-in Asset Creation: Native support for custom tokens without complex smart contracts
3. Stellar Consensus Protocol: Fast finality perfect for real-time reward distribution
4. Account-based Model: Simplified user experience for environmental activists
5. Soroban Smart Contracts: Modern WebAssembly-based contract platform for complex logic

Stellar Architecture Adaptations:

1. DCU Token Implementation

• Use Stellar native assets for the DCU token
• Implement distribution logic through Soroban contracts
• Leverage Stellar's built-in asset controls for pre/post-TGE phases
• Utilize claimable balances for pending rewards

2. dIP NFT System on Stellar

• Implement through Soroban contracts with unique asset creation
• Use Stellar's account-based model for soulbound characteristics
• Leverage data entries for comprehensive metadata storage
• Implement upgrade logic through contract interactions

3. PoI Verification System

• Soroban contract for submission and verification logic
• Integration with off-chain verification services
• Use of Stellar's memo field for submission references
• Multi-signature verification for high-value claims

4. Reward Distribution

• Automated distribution through Stellar's payment operations
• Path payments for complex reward calculations
• Scheduled payments using Stellar's time-based features
• Integration with DEX for token liquidity post-TGE
