LittleBit is an educational library of Bitcoin primitives, with implementations in Python and Rust.
- Help the reader understand how Bitcoin really works at a fundamental level.
- Focus on readability in the Python implementation; on correctness, and performance in the Rust implementation.
- Zero (ish) dependency on third-party packages.
DISCLAIMER: This software comes sans warranty. Do NOT use this code for anything other than educational purposes. I beg you.
