qxtrue
qxtrue is a protocol and reference implementation for verifiable queries in distributed data systems. It provides a framework for clients to confirm the correctness of query results and the provenance of data without re-executing computations or downloading entire datasets. The design uses authenticated data structures and succinct cryptographic proofs. Each data operation yields a compact proof that accompanies the response, allowing verification against public parameters. This approach supports integrity, authenticity, and traceability, using components such as authenticated logs, Merkle proofs, and optional zero-knowledge elements to protect sensitive inputs.
History and scope: The concept emerged in open-source discussions on verifiable computation in the early 2020s
Applications and reception: qxtrue targets distributed databases, data marketplaces, and edge computing environments where multiple parties
Limitations: The protocol adds overhead for proof generation and verification and may require trusted setup or
