Open Quantum Safe organization build librarys for prototyping and experimenting with quantum-resistant cryptography, including post-quantum signature algorithm Falcon. The librarys is implement in many program languages, such C, C++, JAVA, PYTHON, GO, RUST, C#, etc. It's a very good reference for tidecoin app developers. For example, java's falcon library is:
