Build a cryptocurrency! - Blockchain in Rust #01: Blocks
Have you ever wanted to build your own cryptocurrency? Or learn Rust? Well, now you can. This is the first video in a series in which we will build a basic blockchain-based cryptocurrency in the programming language Rust. Dont know Rust? No problem! Ill be explaining some of the basics of Rust programming along the way. This tutorial series will be easier to follow if you have experience with lower-level/systems programming in languages like Assembly, C, or C and/or if you have experience with languages that have strict/complex type systems like Java or Haskell (at least stricter than Python or JavaScript).

NOTE: YES, THERE IS A LONG INTRO. I wanted to make sure I explained enough concepts for people new to Rust or blockchain to understand. Most of my videos are about web development, so I do not expect my typical viewers to have experience in these realms! 15:54 is where I start actually coding.
