🧠 What's inside UltrafastSecp256k1:

• BMI2/ADX asm → 3-5× speedup
• CUDA batch: 4.63M keys/sec
• Montgomery batch inverse
• GLV endomorphism
• Zero heap allocs in hot paths
• Constant-time ct:: namespace
• All primitives from scratch

No boost. No openssl. No libsecp256k1. Just C++20.

C++ Insights - Episode 70: Efficiently passing a std::source_location object

In this episode, I'll answer a question from a viewer about how to efficiently pass a std::source_location object.

The blog post I mention in the video is: https://andreasfertig.com/blog/2025/12/cpp20s-stdsource_location-in-action/

Lập trình viên tối ưu Matching Engine (hệ thống khớp lệnh) đạt 150 triệu lệnh/giây chỉ với một nhân CPU bằng C++20.

Điểm nổi bật:
- Hiệu suất: 156M lệnh/giây (benchmark) và 132M lệnh/giây (dữ liệu thực Binance).
- Độ trễ: < 1 micro giây.
- Kỹ thuật: Zero Allocation (std::pmr), Lock-free (SPSC Ring Buffer), và tối ưu Cache (Flat vectors thay cho std::map).

Dự án mã nguồn mở trên GitHub dành cho ai quan tâm đến HFT và tối ưu hệ thống.
