A Noob's Journey to Blockchain Development in Rust

Introduction

When I picked up Rust, I wanted more than just another programming language. My goal was to build a foundation strong enough to carry me into blockchain development. I also decided to explore low-level programming , as opposed to Python and Javascript, which I was already familiar with (I know some will say Rust is a partial low-level language). I wanted to challenge and change how I think about systems programming.

This drive led me to my first hands-on project, setting the stage for bigger things ahead. This article is the first chapter of that journey. I'll share how I built a ticket validator CLI in pure Rust, what I learned along the way, and how this project fits into my larger roadmap: moving from Rust fundamentals to Solana, Near, and eventually Substrate (yeah, it seems like a lot, but I plan to explore features in these blockchains mentioned, with primary focus on Solana).

I'm taking a domain-based path here, applying what I learn directly to blockchain scenarios so I don't just memorize syntax and forget it. This approach helps me retain knowledge by building projects related to my goals.

The Reason I Picked Rust

Rust seemed like a good option due to current articles, videos, and reviews about its usage in production, highlighting its performance, safety, and memory management. Its strictness seemed like a nice choice if I intend to create a reliable blockchain that is to have a no-trust system.

I considered Go and Python, but Go seems not to be heavily used in the crypto world, and Python's dynamic types were a no, as I planned to go with a statically typed language. It is not as performant as Rust (and yes, I love Python). This is a personal opinion, as I have no desire to involve myself in language or framework wars.

Rust's borrow checker has caught memory bugs in my code that Python's flexibility might overlook, and its speed edges out Go in high-stakes blockchain environments where every millisecond counts.

With Rust chosen, the real test began: struggling and understanding its unique rules and rethinking my coding habits.

Learning Curve

Rust had me on the ropes😅🥲. The ownership system made me rethink my approach to data and usage before I even began coding. Each piece of data became extremely important to understand, not just another variable to use. I learnt to approach my code thinking about each data's lifetime to avoid using a value that has been dropped from memory and might create a dangling pointer (accessing data in memory that has been deleted).

Rust does not have a garbage collector, so it enforces rules that make you consider each piece of data and the memory it occupies on the system, be it on the stack or heap, since Rust automatically cleans data that goes out of scope.

This gave me more insight into how data used in my code is stored and accessed. For example, in my CLI project, I hit a wall trying to borrow a string after moving it to a function. Rust forced me to clone it instead, teaching me to plan data ownership upfront and avoid runtime errors that could plague a blockchain app.

Resources That Helped

The official Rust Book was my holy grail. I read it online chapter by chapter, focusing on text to skip bandwidth-heavy videos due to data limitations😅. Paired with Rustlings exercises (a ~50MB download of interactive CLI drills), it reinforced concepts like borrowing through hands-on fixes. This combo kept things practical and domain-focused, letting me apply lessons straight to blockchain ideas instead of being stuck in tutorial hell.

You can spin up an offline version of the rust book with rustup after installation:

rustup doc --book

for the standard library

rustup doc --std

Journey So Far

After getting to Chapter 12 of the Rust Book, I decided to create a ticket validator CLI app to implement what I've learned, as my goal is to link it to the blockchain and make a working app which allows users to buy and sell tickets for events, with minimal gas fees to maximize profits.

What does it do so far? In pure Rust, it handles basic ticket creation, validation, and hashing using crates like serde for JSON serialization and ed25519-dalek for signing secure checks, making it modular and efficient for future Web3 integration.

For now, this CLI serves as a solid proof of concept, showing Rust's power in action. I'll share more details about my progress with the ticket CLI app in future posts. This article is just an introduction.

Conclusion

Building the ticket validator taught me more than syntax. It showed me how Rust enforces discipline through ownership, error handling, and modular design. These lessons are exactly what I’ll need as I move into blockchain frameworks where reliability and security are non-negotiable. This project is just the beginning. Next, I’ll be working with Solana’s Anchor framework to mint tickets at scale.

If you’re also learning Rust or curious about blockchain, I hope my journey gives you a clear example of how starting small can lead to bigger systems. Follow along, and let’s grow together.
