TrustworthyComputing/T2-FHE-Compiler-and-Benchmarks

The T2 FHE Compiler represents a significant research effort from the mid-2010s, likely originating from Microsoft Research (given the 'TrustworthyComputing' handle and 'T2' branding). With only 39 stars and zero recent activity over a 5.6-year lifespan, it is functionally a legacy project. While it successfully bridged high-level code to FHE circuits using LLVM, the field has moved toward more modern IRs and specialized hardware acceleration. Current leaders like Zama (Concrete/TFHE-rs) and Google (HEIR/XLS) offer significantly more robust, active, and performant toolchains. The project's defensibility is low because it lacks a community, modern FHE scheme support (like advanced CKKS optimizations), and integration with hardware accelerators (GPUs/TPUs/ASICs). Platform domination risk is high as major cloud providers (Microsoft, Google, AWS) are developing their own integrated privacy-preserving stacks that will likely abstract away the need for standalone third-party research compilers.
