Nevertheless, zero-knowledge proofs are computationally complex and consume a high amount of gas. In a high gas cost environment, gas fees would prove to be prohibitively expensive. As the recent successes of Binance Smart Chain and Polygon have shown, the primary concern for users is fees, and users are willing to make certain trade-offs with regards to security when fees are low. As the zero-knowledge implementation is built into the liquidity pool and cannot be opted out of, this may disincentive users from using the liquidity pools.
