Computational efficiency in secure multi-party computation (MPC) for privacy transaction auditing faces inherent trade-offs between security and speed. Optimizations include using arithmetic-friendly elliptic curves (e.g., BLS12-381) to reduce modular exponentiation overhead. Implement batch verification techniques to process multiple transactions simultaneously, cutting latency by 40-60%. Leverage preprocessing phases in protocols like SPDZ to shift computation offline. Employ GPU acceleration for matrix operations in zero-knowledge proofs, achieving 3-5x speedups. Balance security parameters (e.g., 128-bit vs 256-bit encryption) based on risk assessments, with hybrid models using stronger crypto for high-value transactions.
