<ul data-eligibleForWebStory="false">Fully Homomorphic Encryption (FHE) allows computations on encrypted data without needing to decrypt it first.Zama, a French startup, is working on open-source infrastructure to make FHE usable for developers in web3 applications.The combination of blockchain and FHE offers potential use cases like private DeFi, healthcare on-chain, private voting, and decentralized identities.Zama's tools, like fhEVM, enable developers to build privacy-preserving decentralized applications without entirely changing their tech stack.
