When Smart Contracts Need Private Data Smart contracts are good at executing transparent rules. But what happens when those rules depend on information that shouldn’t be public? A lending application may need to assess financial data. A business may need to verify its reserves. An institution may need to process sensitive records onchain. Making all that information public is not always practical. @primus_labs explores how FHE can enable computation on encrypted data, helping applications work with information without exposing its underlying values. This opens an important design possibility smart contracts that can work with sensitive information without requiring everyone to see it.
