🧠 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.

Exploring the world of the artist known as ECDSA!

In the latest TechAptitude post we dive into the primary cryptographic algorithm used in many blockchain based systems including Bitcoin and Ethereum, Binance Smart Chain, and Avalanche - Elliptic Curve Digital Signature Algorithm (ECDSA).

We review ECDSA and how it secures cryptocurrencies like BitCoin and Ethereum.

Một lập trình viên đã tối ưu tốc độ thư viện đường cong Elliptic, chỉ sử dụng lý thuyết nhóm thuần túy trong toán học, mà không cần đến lập trình cấp thấp (assembly) hay tăng tốc GPU (CUDA). Đây là một thành tựu đáng chú ý trong việc cải thiện hiệu suất mật mã.

The #Monero community is excited to announce the launch of the FCMP++ (Full-Chain Membership Proofs) Optimization Coding Competition!

The best solution for each implementation will be awarded 250 XMR (currently ~53k USD) and 100 XMR (~21k USD)

See all contest details here: https://github.com/j-berman/fcmp-plus-plus-optimization-competition

What isn't linked from those four pages above, however, is the one gem I had been pointed to some time ago. And hadn't made the connection that this was the same person!

Michael Driscoll's «The Animated Elliptic Curve» really helped me in understanding Elliptic Curve Cryptography with its wonderful, well-described animations which you can replay until you understand them.
