FHE-SQL: Fully Homomorphic Encrypted SQL Database

FHE-SQL targets a significant weakness in first-generation encrypted databases like CryptDB: leakage through access patterns and frequency analysis. However, as an open-source project with 0 stars and 3 forks, it currently lacks any market traction or community momentum. While the underlying cryptography (FHE) is deep-tech, the implementation is essentially an academic reference for a paper (arXiv:2510.15413v1). The defensibility is low because the project is easily reproducible by researchers and lacks the production-grade optimizations required for commercial FHE use (which is notoriously slow). From a competitive standpoint, it faces heavy pressure from well-funded specialized firms like Zama (Concrete SQL), Enveil, and Duality Technologies, as well as big-tech initiatives like Microsoft's SEAL-based applications and Google's Confidential Computing. Platform domination risk is high because cloud providers (AWS, Azure, GCP) are the natural aggregators for 'Confidential SQL' as a managed service once FHE performance reaches a viable threshold. The project is valuable as a pedagogical tool or a starting point for research but is currently a high-risk bet for technical investment without significant performance breakthroughs or community adoption.
