    Hey everyone! I’m grinding for a blockchain developer interview and trying to level up my Rust skills. Could use some real-world advice:

    1. Project ideas? I want to build stuff that’s actually relevant to blockchain—like messing with smart contracts or crypto functions (hashing, signatures). What’s worked for you?

    2. Ownership/memory safety is kicking my butt. How did you finally ‘get’ this part of Rust? Any exercises, analogies, or “aha” moments that made it click?

    3. Rust + blockchain folks: If you’ve used Rust in this space or aced a similar interview, drop your go-to resources, tips, or “I wish I knew this earlier” advice.

    Seriously, even a one-liner helps. Thanks in advance! 🙏

    If you're preparing for a blockchain developer interview and improving Rust skills, start by building a basic blockchain (tutorial: Building a Blockchain in Rust). For smart contracts, use Ink! on Polkadot (Ink! Docs). Combine this with Rustlings exercises (Rustlings) to master ownership and memory safety concepts.

    Create projects like a cryptographic wallet with ECDSA (ECDSA in Rust Guide) or prototype a decentralized IoT network. Contribute to open-source projects like Substrate (Substrate GitHub) to gain practical experience. Solve Rust problems on LeetCode to improve algorithmic skills.

    For learning, follow The Rust Programming Language (Rust Book) and explore Polkadot-specific tutorials (Polkadot Dev Docs). Join forums like Rust Reddit or Discord to engage with developers. Use tools like Clippy (Clippy Guide) and Cargo (Cargo Docs) to improve coding efficiency.

    If you’re preparing for a blockchain developer interview and focusing on Rust, here’s what worked for me:

    Practical Projects: Build a custom token smart contract on platforms like Solana or Near to demonstrate blockchain expertise. Another great idea is creating a multi-signature wallet, which will teach you cryptographic functions in Rust.

    Ownership Model and Memory Safety: Focus on small exercises like implementing linked lists or custom data structures. Tools like Rustlings are perfect for practicing borrowing, lifetimes, and error handling (Result and Option).

    Resources: I highly recommend Zero to Production in Rust for overall mastery and Solana’s developer guide for blockchain-specific use cases.

    These steps helped me solidify my Rust knowledge and build confidence for interviews. Good luck—you’ve got this!

    If you're preparing for a blockchain developer interview with a focus on Rust, here’s what I’d suggest:

    Project Ideas: Try building your own ECDSA (Elliptic Curve Digital Signature Algorithm) or a simple consensus algorithm like PBFT. These are practical ways to see how cryptography fits into blockchain while showcasing your Rust skills.

    Ownership Model: Dive into cryptography-related code to understand Rust’s ownership and lifetimes. Play around with libraries like ring or ed25519-dalek—they’re great for hands-on experience with memory safety in cryptographic operations.

    Resources: Check out RustCrypto libraries on GitHub for inspiration. I also recommend reading cryptography papers and coding small parts of the algorithms in Rust. It’s a great way to learn both theory and practice.

    Let me know if you need links or other suggestions!
