I made a zero dependency Bitcoin math implementation in C

In plain words

This is a C library that implements Bitcoin mathematical operations without requiring any external dependencies. It's designed for developers who need to perform cryptographic calculations related to Bitcoin in their applications. What stands out is its minimal approach—by eliminating dependencies, it reduces complexity and potential security concerns while making integration straightforward for systems-level programming projects.

WARNING: THIS PROGRAM USES THE rand_s FUNCTION FROM THE WINDOWS stdlib.h TO GENERATE PSEUDO RANDOM ENTROPY. MICROSOFT STATES THAT rand_s PRODUCES CRYPTOGRAPHICALLY SECURE RANDOM NUMBERS . HOWEVER, USERS SENDING COINS TO RANDOM ADDRESSES GENERATED BY THIS PROGRAM DO SO AT THEIR OWN RISK! I started the bitcoin_math project in order to teach myself the basics of Bitcoin math from first principles, without having to wade through the source code of any of the crypto or "bignum" libraries on which standard Bitcoin implementations in Python depend. My goal was to collect together a minimal set of functions in a single C source code file with no dependencies other than the following standard C…from github.com

  I built a minimal Forth-like stack interpreter library in C2025 · ▲47

  This weekend I created stacklib.h - a single-header library that brings Forth-style stack operations to C. It implements a basic interpreter with: - Stack operations (push/pop/dup/swap/over/drop) - Arithmetic (+, -, *, /) - Output (., emit, cr) - Stack inspection (.s, depth) Example usage: Stack s; stack_init(&s); dict_init(); exec(&s, "10 20 + ."); // Prints "30" exec(&s, "1 2 3 4 .s"); // Shows stack contents The library is self-contained, requires no dependencies, and handles basic error checking. It was inspired by wanting to understand…

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  I built a hardware processor that runs Python▲983

  Hi everyone, I built PyXL — a hardware processor that executes a custom assembly generated from Python programs, without using a traditional interpreter or virtual machine. It compiles Python -> CPython Bytecode -> Instruction set designed for direct hardware execution. I’m sharing an early benchmark: a GPIO test where PyXL achieves a 480ns round-trip toggle — compared to 14-25 micro seconds on a MicroPython Pyboard - even though PyXL runs at a lower clock (100MHz vs. 168MHz). The design is stack-based, fully pipelined, and preserves Python's dynamic typing without static type restrictions.…
