Homomorphic Encryption

Definition ∞ Homomorphic encryption is a form of encryption that allows computations to be performed on encrypted data without decrypting it first. The results of these computations, when decrypted, match the results that would have been obtained if the computations were performed on the original unencrypted data. This enables secure processing of sensitive information.
Context ∞ The relevance of homomorphic encryption in the cryptocurrency and blockchain space is growing, particularly concerning privacy-preserving transactions and secure data analysis on decentralized networks. Current discussions often center on the computational cost associated with these schemes and the development of more efficient algorithms. Future advancements are anticipated in enabling complex smart contract operations and data analytics on encrypted blockchain data.
