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.
