🔐 Obscura NFTs as Confidential Assets

Deep dive into the privacy technology powering Obscura NFTs.

What Are Confidential Assets?​

Obscura NFTs are built using Zano's Confidential Asset feature, providing full privacy by default. When you hold or transfer an NFT on Obscura, the blockchain hides:

  • 🎭 Ownership - No one can see which wallet owns which token
  • 🔄 Transfers - Transaction history remains private
  • 💰 Balances - Wallet holdings are completely hidden
  • 📊 Activity - Trading patterns cannot be tracked
Native Privacy

Confidential Assets are a native feature of the Zano blockchain, not an add-on or layer 2 solution. Privacy is built into the protocol itself.

How Privacy Works​

The Technology Stack​

Every transaction uses a one-time address, making it impossible to link recipients to their wallet addresses.

Result: Public blockchain observers cannot determine who received an NFT.

Privacy Comparison​

Traditional NFTs vs Obscura​

│ Owner Address: Public           →  Owner: Hidden ✓
│ Transfer History: Visible       →  Transfers: Private ✓

Key Difference

On traditional blockchains, anyone can see who owns which NFTs. On Obscura, only the owner knows what they hold.

Technical Deep Dive​

Issuance & Distribution​

When an Obscura NFT collection is created:

  1. Asset Registration - Creator registers a new confidential asset type
  2. Metadata Embedding - NFT data stored on IPFS, hash embedded in asset
  3. Private Minting - NFTs created with hidden supply and distribution
  4. Encrypted Transfers - All movements use Zano's privacy protocols

Verification Without Exposure​

Users can prove ownership without revealing their holdings:

// Conceptual flow
User wants to prove they own NFT #42

Option 1: View Key Sharing
└─ Share read-only view key
   └─ Verifier confirms NFT ownership
      └─ Cannot see: other holdings, balance, history

Option 2: Asset Signature
└─ Sign message with NFT ownership
   └─ Cryptographic proof of possession
      └─ No wallet data exposed
Selective Disclosure

Obscura supports voluntary transparency - owners can prove holdings when needed (e.g., for airdrops or verification) without making data permanently public.

Privacy Benefits​

For Collectors​

  • 🎭 Anonymous Collecting - Build collection without public profile
  • 🔒 Whale Privacy - Large holders stay hidden
  • 💼 Trading Privacy - Buy/sell without exposure
  • 🎯 No Targeting - Cannot be targeted based on holdings

For Creators​

  • 🎨 Private Distribution - Issue NFTs without exposing recipients
  • 📊 Hidden Metrics - Collection stats stay private
  • 🔐 Holder Privacy - Protect your community's identity
  • 💎 Fair Launches - No front-running based on whale wallets

Smart Contract Comparison​

Traditional Approach​

// Public NFT contract (Ethereum)
contract PublicNFT {
    mapping(uint256 => address) public owners;  // ❌ Public ownership
    
    function transfer(address to, uint256 tokenId) {
        // ❌ All transfers visible on-chain
        owners[tokenId] = to;
    }
}

Obscura Approach​

Obscura NFT (Zano Confidential Asset)
├─ No smart contract needed
├─ Native blockchain privacy
├─ Protocol-level encryption
└─ Zero on-chain exposure
No Smart Contract Vulnerabilities

Without smart contracts, there's no risk of exploits, reentrancy attacks, or approval vulnerabilities common in EVM-based NFTs.
