About Sunscreen
Sunscreen is working to bring fully homomorphic encryption (FHE) to the masses, starting with web3. Their goal is to enable a new class of applications operating on private shared state by making FHE both fast and usable for developers. They are building an FHE compiler and a ZKP compiler to empower developers to bring privacy to any application they are creating. Sunscreen's work enables applications across finance, prediction markets, and machine learning, with specific use cases demonstrated in private verifiable auctions and truly dark dark pools. The company also runs a grants program to encourage further research and development into FHE. The core team consists of experts in cryptography, engineering, high-performance computing, and strategy from companies like NuCypher, Tableau, Microsoft, Meta Research, Caldera, and Two Sigma.
