fully proven sha256 implementation in Bend 2. Next AUTOResearch it to improve its performance and make it at least only 2x slower than the optimized version (very positive with early result): https://github.com/Giulio2002/bend-sha256 I created an agentic pipeline for this so other cool projects are running through…

another 2x to bend-sha256: https://github.com/Giulio2002/bend-sha256/commit/6dcf2ae0fabac2591b7d90106e3ea5cc479ba1e1, now this is 1.5x to C on Arm (hashlib, Go's is mogs us harder) and still behind by 8x on arm 😅 (need the SHA hw acceleration). The benchmarks are getting ridiculous tho. now lean is around 20x slower.
