When comparing zero-knowledge proofs (ZK) and fully homomorphic encryption (FHE), the maturity gap is striking. ZK technology has reached production-grade status, powering live mainnet solutions like Polygon zkEVM, zkSync Era, and Scroll—proven at scale across multiple ZK-rollup deployments. In stark contrast, FHE remains in its infancy: most implementations are still confined to testnets and prototypes, with active development ongoing in research labs. While promising projects are pushing boundaries, FHE hasn't yet achieved the operational maturity that ZK enjoys. This gap reflects not just technical readiness but real-world deployment experience—a crucial factor for blockchain infrastructure.

zk is already full, while FHE is still in the lab gnawing on steamed buns.

zk has already eaten the meat, and fhe is still gnawing on the bones... probably have to wait a few more years.

ZK has already been verified on mainnet, while FHE is still playing in the laboratory. The gap is quite significant. Based on on-chain data performance, governance proposal approval rates and ecosystem activity for projects like Polygon zkEVM and zkSync directly outperform FHE's various testnet projects. It is worth noting that this reflects not only technical issues but also the equilibrium differences in DAO governance and incentive mechanisms—FHE needs to resolve the incompatibility of its economic model before breaking out.

zk is already running on the mainnet, while FHE is still in the lab experimenting. The gap is not just a little or two.
