9. Technical Implementation

9.1 Smart Contract Architecture

9.1.1 Core Contracts

• ZKPay.sol: Main contract, implements privacy payment functionality
• EnclaveToken.sol: Token contract, implements mining and burning
• NFTManager.sol: NFT management contract, implements node management
• NodeNFT.sol: NFT contract, implements node identification
• TokenVesting.sol: Lock-up contract, implements token lock-up
• Treasury.sol: Fund management contract, implements fund management

9.1.2 Auxiliary Contracts

• ZKPayVault.sol: Vault contract
• TreasuryConfigCore.sol: Configuration core contract
• IntentManager.sol: Intent management contract
• Workers: Various Worker contracts (cross-chain, swap, etc.)

9.2 Zero-Knowledge Proofs

9.2.1 SP1 Verifier

• Verification Key: Use verification key to verify proofs
• Public Values: Verify correctness of public values
• Proof Verification: Verify zero-knowledge proofs

9.2.2 Proof Generation

• Node Proof Generator: Each node runs a zero-knowledge proof generator
  • Responsible for generating zero-knowledge proofs required by the Enclave Privacy system
  • Supports generation of Commitment Proof and Withdraw Proof
  • Ensures timeliness and accuracy of proof generation
  • One node can provide proof generation services for multiple NFTs
• NFT Binding Mechanism: One node can bind up to 10 NFTs
  • NFT serves as the unique identifier for node identity
  • Multiple NFTs can share the same node's proof generation service
  • Binding relationship is managed through on-chain contracts
  • Each NFT independently calculates rewards and status
  • Improves resource utilization efficiency and reduces operational costs
• Proof Types:
  • Commitment Proof: Generate allocation commitment proof
  • Withdraw Proof: Generate withdrawal proof
  • Batch Proof: Generate batch operation proof

9.3 Cross-Chain Support

9.3.1 Cross-Chain Bridging

• DeBridge: Supports DeBridge cross-chain
• Other Bridges: Supports other cross-chain bridges
• Native Cross-Chain: Supports native cross-chain functionality

9.3.2 Multi-Chain Deployment

• BSC: Mainly deployed on BSC
• Other Chains: Supports deployment to other chains
• Cross-Chain Interoperability: Implements cross-chain interoperability
