1. Fundamentals of ZKP Technology

Zero-knowledge proofs enable cryptographic verification without data disclosure, with three primary variants demonstrating blockchain applicability:

zk-SNARKs Offer compact proof sizes and efficient verification, though requiring trusted setup ceremonies that introduce centralization risks.

zk-STARKs Provide quantum resistance and transparent setups at the cost of larger proof sizes compared to SNARKs.

Bulletproofs Specialize in efficient range proofs for confidential transactions without requiring trusted setups.

2. Sui Compatibility Assessment

The Move language's architecture presents both opportunities and challenges for ZKP implementation:

Integration Advantages

• Move's modular design permits ZKP circuit incorporation
• Object model could enable privacy-preserving dynamic NFTs
• Parallel execution may accelerate proof verification

Technical Hurdles

• Limited ZKP tooling compatibility with Move
• Prover node requirements may offset Sui's efficiency gains
• Parallel processing complicates rollup implementations

3. Prospective Implementation Use Cases

Confidential DeFi Operations

• Shielded transaction amounts
• Private liquidity pool participation
• Obfuscated trading strategies

Compliant Anonymity Systems

• KYC verification without personal data exposure
• Age-gated access proofs
• Pseudonymous DAO participation

Scalability Enhancements
