In a tweet that could make even the most die-hard crypto nerd pause and say, “Wait, what?”, Vitalik urged developers to measure “overhead as a ratio” when assessing zero-knowledge (ZK) and fully homomorphic encryption (FHE) systems. Why? Because comparing operations per second is, apparently, a bit too pedestrian for Vitalik’s taste. According to him, a ratio reveals the true loss of computational efficiency when you switch from a traditional trust-based system to a fancy, cryptographic one. Seems like a good way to finally figure out how much pain you’re enduring for the sake of security.
