In this course, students will learn Rust programming language by implementing concepts used in bitcoin and interacting with bitcoin software and related crates(libraries) in rust.
Rust is a static strongly typed Systems programming language giving programmers control of computer resources like CPU, memory, threads etc., directly in a safe way. It achieves safety with the help of an expressive type system using Generics and traits and borrow checking.
It is a widely accepted belief in the bitcoin community that bitcoin and related software should be efficient and consume less computing resources so that it can be run on relatively cheap hardware.
C, C++ etc., gives the ability to write efficient, less resource-intensive code but does not guard the programmers from introducing memory vulnerabilities. This is why Rust is now the go-to choice for implementing bitcoin-related software.
This course expects the students to have prior programming knowledge and understanding of basic concepts like variables, loops, functions, user defined types etc., Reading of Chapters 1 to 4 of Rust book, it's not required have thorough understanding, but get your setup up and ready for coding in rust. Understanding of concepts like stack and heap memory, how malloc, every programming language relies on some version of malloc to do memory allocation. Chapter 4 of rust book also discusses about this topic.

This course is sponsored by Chaincode to get more programmers into Rust Bitcoin FOSS. So we expect you to be a self-learner and come up with your own ideas. Every assignment is open ended and can be extended as you wish. If you submit the assignment within the deadline your implementation will be reviewed and you'll get timely feedback.
Three students from the first run of this course have successfully contributed to rust-coinselection repository so far.
During regular sessions groups will be formed. Each group will be provided a set of questions related to rust and bitcoin. Each student will be allocated a question and their job is to explain the concepts to others. Moderators will be provided.
The initial 20 minutes introduction will be conducted by the instructor, followed by 20 minutes of group discussion and the last 20 minutes will be reserved for clarifying open questions and issues.
This is a time specifically to address questions related to rust and bitcoin. A form will be posted where you can add your questions in advance so that the instructor can be prepared.
