swjng/gkr

The 'swjng/gkr' project is a research-oriented implementation of the GKR protocol. While the GKR protocol is a sophisticated piece of interactive proof machinery, this specific repository is effectively stagnant with no velocity (0.0/hr) and very low engagement (73 stars, 5 forks) over a 3.5-year period. In the fast-moving Zero-Knowledge (ZK) landscape, it has been largely superseded by production-grade frameworks like Gnark (which includes GKR optimizations), Plonky2, or specialized hardware-accelerated provers. The defensibility is low because there is no evidence of a community, ongoing audits, or performance benchmarks that would make it a competitive choice for modern ZK-Rollups or verifiable compute applications. The frontier lab risk is low simply because ZK proof aggregation for general circuits is a niche domain primarily relevant to blockchain infrastructure and privacy-preserving compute, areas OpenAI and Google currently treat as peripheral or solve via different primitives. Market consolidation is a major threat here; the ZK space is gravitating toward a few highly-funded, highly-optimized stacks (e.g., Succinct, RISC Zero, Polygon Zero), leaving isolated reference implementations like this one obsolete.
