This systematic literature review scrutinizes the implementation and analysis of zk-SNARK, zk-STARK, and Bulletproof non-interactive zero-knowledge proof (NIZKP) protocols in privacy-preserving applications across diverse sectors. Examining 43 research works published from 2015 to April 2023, we categorized findings into financial, medical, business, general, and other domains. Our analysis highlights significant variations in real-world performance across implementations utilizing NIZKP protocols. However, divergent methodologies in security analyses hindered conclusive comparisons. Addressing research gaps, our future endeavors aim to establish a real-world benchmark for these protocols.

“…Aside from data sharing, data trading can further explore the data value. A blockchain-based digital identity exchange scheme for financial institutions has been proposed [99], in which SNARG is utilized to prove the authenticity of identities in a privacypreserving manner. TEE can be utilized to build a data-trading platform [100,101] that preserves fairness for both buyers and sellers, and ensures on-chain privacy for data processing [102].…”

“…However, the protocol requires a set of trusted users whom the participants need to trust for holding and processing of private information. In [22], the authors proposed a decentralized system for the privacy-preserving exchange of information related to the identities of the users. The system specifically ensures privacy and correctness through the use of a blockchain system and zero-knowledge proof techniques.…”
