Beyond Latency: A System-Level Characterization of MPC and FHE for PPML

The project is currently a research-centric artifact with 0 stars and minimal activity, typical of a newly released academic paper (ArXiv source). Its defensibility is low because it functions as a benchmarking methodology rather than a product with a moat; any researcher or engineer can replicate the characterization setup using standard libraries like MP-SPDZ or OpenFHE. However, it addresses a genuine pain point in the PPML community: the lack of holistic performance metrics beyond simple 'online latency' (e.g., energy consumption, memory overhead, and communication costs). Frontier labs like OpenAI or Google are unlikely to compete directly with a benchmarking suite, as they typically release the underlying primitives (like Microsoft's SEAL or Google's FHE transpiler) rather than objective comparison tools. The 'displacement horizon' is relatively short because the rapid evolution of hardware accelerators (ASICs/FPGAs for FHE) and new cryptographic protocols often renders specific software-level benchmarks obsolete within 18-24 months. The project serves as a valuable reference for system architects but currently lacks the community or software-ecosystem 'gravity' to be considered a defensible platform.
