Data Architecture

0n-Chain Data

Primary Storage:

• User profiles and registration data

• Asset metadata and ownership records

• Share token balances and distributions

• Royalty distribution history

• Verification votes and status

Optimized Storage Patterns:

// Efficient mapping structures
mapping(uint256 => Asset) public assets;
mapping(address => CreatorProfile) public creators;
mapping(uint256 => mapping(address => bool)) public userVotes;

// Packed structs for gas optimization
struct Asset {
    uint256 nftTokenId;        // 32 bytes
    address ipId;              // 20 bytes
    uint256 licenseTermsId;    // 32 bytes
    // ... other fields
}

Off-Chain Data

IPFS Storage:

• Asset media files (audio, video, images)

• Detailed metadata JSON

• Profile photos and media

• Documentation and descriptions

Centralized Storage (Optional):

• Cached data for faster UI loading

• Analytics and metrics

• User preferences and settings

Security Architecture

Access Control

Role-Based Permissions:

// Platform owner permissions
modifier onlyOwner() { ... }

// Creator permissions
modifier onlyCreator(uint256 assetId) { ... }

// Asset existence validation
modifier assetExists(uint256 assetId) { ... }

Security Patterns

Reentrancy Protection:

import "@openzeppelin/contracts/security/ReentrancyGuard.sol";

contract UniversalAssetTokenizationPlatform is ReentrancyGuard {
    function buyAssetShares() external payable nonReentrant {
        // Protected against reentrancy attacks
    }
}

State Validation:

• Input parameter validation

• Existence checks before operations

• Overflow/underflow protection

• Access permission verification

Economic Security

Platform Fees:

• 5% fee on royalty deposits

• Prevents spam and funds development

• Incentivizes quality content creation

Share Distribution Limits:

• Creators must retain 10-90% of shares

• Prevents complete ownership transfer

• Maintains creator incentive alignment
