Homomorphic Aggregation

Algorithm

Homomorphic aggregation represents a cryptographic technique enabling computations on encrypted data without decryption. This process allows for secure aggregation of data from multiple sources, a critical feature in decentralized finance (DeFi) and privacy-preserving applications. The core principle involves performing operations on ciphertexts, producing an encrypted result that, when decrypted, matches the outcome of the same operations performed on the original, unencrypted data. Such functionality is particularly valuable in scenarios involving sensitive financial data, such as calculating aggregated portfolio risk or determining consensus in a blockchain network.
