Zama is an open-source cryptography company working on Fully Homomorphic Encryption (FHE), a technology that lets you perform calculations on encrypted data without decrypting it first. This is crucial for keeping sensitive information private, especially in blockchain and AI, where data security is a big concern. Imagine doing math on a locked box without ever opening it—that’s FHE in action! As of July 13, 2025, Zama has raised $57 million in funding, becoming the first FHE unicorn with a valuation over $1 billion, and their public testnet is now live, letting developers build privacy-focused apps.

Why It MattersThe evidence leans toward FHE being a game-changer for blockchain privacy. Public blockchains are transparent, which can compromise user data, but FHE allows computations without exposing the data. This could make blockchain more secure for financial transactions, identity management, and more, addressing a key barrier to adoption. However, some in the crypto community debate its scalability and real-world use, so it’s not without challenges.

Use Cases and Impact on BlockchainHere are some ways FHE could change blockchain: Private Token Transfers: Transfer tokens without revealing your balance, keeping finances confidential. DeFi Apps: Build decentralized finance apps where financial data stays encrypted, protecting user privacy. Secure Medical Records: Process encrypted medical data on-chain without exposing patient information, ideal for healthcare. Research suggests FHE could become the standard for confidential transactions, making blockchain more private and user-friendly, but its adoption depends on overcoming technical hurdles.
