Post-quantum crypto stack, but novelty is in motivation not implementation.
Zero-deps Rust crypto with 1.61x benchmark wins over ring and rustls.
CoreML as an accelerator, not end-to-end runtime—1.8× speedup on M4 chips.
This reads like a GPU engineer's field notes — one ~3,400-line CUDA file implements a full per-thread crypto pipeline (key gen → EC multiply → SHA-256 → RIPEMD-160) and a two-stage bloom+binary-search matcher to check ~3,100 targets at ~100M keys per batch. The article digs into concrete low-level choices (LUT layout, memory hierarchy, __ldg reads, atomicCAS reporting, and per-mode keygen strategies), which is rare in public writeups; downside is it's closed-source and the dual-use/ethical implications should be called out more explicitly.
Post-quantum privacy blockchain built from scratch, but Monero already does ring signatures well.
Direct2D GPU PDF renderer with CPU fallback, but alpha-stage and Windows-only.
