Here is the full English translation of the proposal, keeping the structure and nuance:

---

✅ Goal

To combine smart contracts and image-generation AI so that revenue from derivative works automatically flows back to the original (primary) creators.

---

🎯 Key Points for Implementation

1. A system where primary creators register their rights
2. The AI can track which primary work a new image is based on
3. That information is passed to a smart contract
4. Revenue is automatically split when the derivative work is sold or used

---

🔧 Overall Architecture

[1] Rights Holder Registration Platform
      ↓ (Issues a “Work ID” as an NFT/token)
[2] Rights Metadata Registry (on-chain or hybrid)
      ↓ (AI can reference these rights)
[3] Image-Generation AI
      ↓ (Outputs which Work IDs were used + similarity scores)
[4] Smart Contract
      - Primary creator address
      - Secondary creator address
      - Royalty share
      - Referenced Work ID
      Automatically distributes revenue
      ↓
[5] Marketplace
      - Applies royalty split at sale time

---

🌱 1. Tokenizing Primary Works as “Work IDs”

Primary creators register like this:

▶ Mechanism

• Hash the original work (image → SHA-256)
• Mint an NFT (ERC-721 or ERC-1155) containing the hash as metadata
• NFT is linked to the creator’s wallet

▶ Benefits

• Ownership is publicly verifiable on-chain
• Disputes are reduced
• Derivative works can explicitly reference the original Work ID

---

🧠 2. AI Associates the Generated Image with a Primary Work

Method A: User specifies the primary Work ID

Example:
“Generate an image based on Work ID #123.”

The AI outputs: used_work_id = 123.

Method B: AI auto-detects similarity

• Extract features from the generated image
• Compare them to registered works
• If similarity > threshold (e.g., 0.80), auto-link the Work ID

This allows the AI to declare which primary work influenced the derivative.

---

💰 3. Revenue Sharing via Smart Contract

Required fields in the smart contract

struct RoyaltyInfo {
    address primary_creator;      // Primary creator
    address secondary_creator;    // Derivative creator
    uint256 primary_share;        // e.g., 30%
    uint256 secondary_share;      // e.g., 70%
    uint256 referenced_work_id;   // Original Work ID
}

Revenue flow

1. Derivative work is sold as an NFT
2. Payment goes into the smart contract
3. Contract automatically sends the appropriate portion to the primary creator
4. Remaining amount goes to the derivative creator

Royalties also apply to secondary sales (via ERC-2981 etc.)

---

🛒 4. Marketplace Integration

At sale time:

• Payment is sent to the contract
• Contract calculates royalties
• Funds are automatically distributed to primary & secondary creators

---

💡 Practical Issues & Solutions

① Legality of copyright

Minting NFTs of others’ works is illegal.
→ Use an official registration system where primary creators register their own works.

---

② Accuracy in detecting referenced works

→ Improve similarity models
→ Optionally let creators publish feature vectors of their works for better matching.

---

③ Gas fees

→ Use L2 chains like Polygon or Arbitrum for low-cost transactions.

---

🌟 Extensions & Advanced Ideas

1. Foundation for a new “creator economy”

Primary creator registers →
Fans create derivative works →
Each sale generates automatic royalties →
Sustainable creator ecosystem

---

2. Automatic “AI training license fees”

When the AI trains on a work with a registered Work ID:
→ Automatically send micro-payments to the rights holder.

---

3. Blockchain transparency of derivative creation

• Which primary work was referenced
• How much revenue was generated
• How much royalty was paid

All transparently recorded on-chain.

---

📌 Summary

Combining smart contracts + image-generation AI can realistically create a system where:

• Primary works have on-chain Work IDs
• AI indicates which Work ID it referenced
• Smart contracts automatically distribute royalties
• Marketplaces handle payments without manual intervention

This is technically feasible today.

🔧 If you want, I can also produce:

• A prototype Solidity smart contract
• Metadata schema (JSON)
• API design for the AI system
• Similarity detection pipeline
• Full architecture diagrams
