TechFlow, Oct 18 — Ethereum co-founder Vitalik Buterin posted on social media today, suggesting that developers in the zero-knowledge proof (ZK) and fully homomorphic encryption (FHE) fields adopt more practical performance evaluation metrics. He proposed using an "efficiency ratio"—the ratio of encrypted computation time to original computation time—instead of the traditional "operations per second" metric.
Buterin noted that this method is hardware-independent, clearly reveals the efficiency cost of using encryption techniques, and allows developers to make simple estimations based on known original computation times. Although he acknowledged limitations due to differences in SIMD/parallelization and memory access patterns, he believes this metric remains valuable.
