5. Privacy Protection Capability Analysis
5.1 Transaction Process Privacy Protection
- Identity Privacy: No direct association between payer and recipient, completely hiding identities of both transaction parties
- Amount Privacy: Specific allocation amounts are only known to relevant parties, third parties cannot infer through on-chain data
- Relationship Privacy: Recipients are unaware of each other's existence, protecting transaction relationship networks
- Time Privacy: Transaction time information is protected, preventing behavioral inference through time pattern analysis
5.2 Digital Asset Privacy Protection
- Asset Origin Privacy: Hides the original source and circulation paths of assets, preventing on-chain tracking
- Asset Holding Privacy: Protects user asset holdings, preventing wealth exposure
- Asset Distribution Privacy: Protects asset distribution across different chains, preventing cross-chain correlation analysis
- Asset Portfolio Privacy: Protects investment portfolio information, preventing investment strategy leakage
5.3 On-Chain Wealth Management Privacy Protection
- Wealth Distribution Privacy: Protects users' wealth distribution across different chains
- Management Strategy Privacy: Protects wealth management strategies and decision processes
- Allocation Plan Privacy: Protects allocation plans and amounts to multiple recipients
- Fund Flow Privacy: Protects fund flow information, preventing on-chain analysis and tracking
5.4 Double-Spending Prevention
- Deposit Layer: Each Deposit ID can only be used once
- Proof Layer: Each proof hash can only be used once
- Commitment Layer: validCommitments ensures commitment validity
5.5 Anti-Replay Attack
- Uses proof hash to prevent proof replay
- Uses nonce mechanism to prevent transaction replay
- Timestamp verification prevents use of expired proofs
5.6 Formal Verification
Core smart contracts and zero-knowledge proof circuits have undergone formal verification to ensure security.
