The project is an experimental prototype focused on a highly specialized niche: the intersection of Zero-Knowledge Proofs and Linked Data. With only 21 stars and zero velocity over more than four years, it lacks any meaningful community adoption or ecosystem moat. While the concept of selective disclosure for RDF graphs is technically interesting for Decentralized Identity (DID), the industry has largely pivoted towards more standardized approaches like SD-JWT (Selective Disclosure for JWT) and BBS+ signatures, which are supported by larger consortiums like the Decentralized Identity Foundation (DIF) and W3C. Competitors include established identity players like SpruceID, Transmute, and Matter Labs (for more general ZK infrastructure). This repository serves as a historical or academic reference rather than a production-ready tool, and its low defensibility stems from its lack of maintenance and the emergence of superior, standardized alternatives.
