Homomorphic Encryption
Web3 / privacy technology
Homomorphic encryption is an advanced cryptographic technique that allows mathematical operations to be performed directly on encrypted data without requiring decryption first. The results of computations on encrypted data remain encrypted and, when decrypted, produce the same results as if the operations had been performed on plaintext data. This property enables cloud computing and data analysis on sensitive information while the data remains protected from the computing service itself, as the processor never accesses unencrypted values and cannot learn anything about the underlying data. Example: The Zama network developed homomorphic encryption solutions for blockchain and decentralized finance, allowing smart contracts to perform computations on encrypted user data. This enables privacy-preserving dApps where users can submit encrypted information and receive computed results without revealing their raw data to the contract or other parties. Why it matters for privacy technology: Homomorphic encryption solves the fundamental problem of maintaining privacy while requiring computation. It enables Web3 applications to process sensitive financial data, health information, or personal details without centralizing trust or exposing information during the computation process.
