Predicate Queries

Definition ∞ Predicate queries involve retrieving data from a dataset based on a specific condition or set of criteria, rather than an exact identifier. Instead of seeking a single known item, these queries search for all data elements that satisfy a given logical statement. This allows for more flexible and complex data filtering.
Context ∞ In the context of blockchain and privacy-preserving data, predicate queries are a significant area of research and development. Technologies like zero-knowledge proofs are being explored to allow users to query data based on conditions without revealing the query itself or the underlying data. News reports might discuss advancements in secure computation that enable such conditional data access while maintaining user privacy and data confidentiality.
