Rust Utils: Strengthening Qubic’s Core Protocol

Qubic runs on a custom-built protocol. Every transaction, contract execution, and consensus mechanism depends on precise, efficient, and reliable networking. But up until now, one key piece has been missing - a fully developed Rust-based implementation of the Qubic protocol.

That’s where Rust Utils comes in.

This project completes the protocol and networking layer for Qubic, ensuring faster, safer, and more modular infrastructure. Built for performance and security, it finalises essential networking features while setting the stage for future improvements in miners, pools, and smart contracts.

And now, thanks to the Qubic Grants Program, Rust Utils is being completed.

What Rust Utils Does

Rust Utils is about building a solid foundation for Qubic. Here’s what’s already done:

• FourQ Cryptography → A pure Rust implementation, ensuring secure and efficient cryptographic operations.

• Wallet Features → Seed/private key generation, public key creation, signing - everything needed for secure wallet interactions.

• Core Protocol Functions → Handling headers, messages, and serialisation so that transactions and network requests flow smoothly.

• Networking Stack → The ability to send and receive packets over TCP, both in persistent connections and on-demand requests.

• Smart Contract Interactions → Querying QX, SendMany, voting contracts, and other core network features.

Everything is modular. Meaning? Custom networking, serialisation, and signing methods can be easily integrated.

Now, the final step: completing the protocol and testing it for real-world deployment.

Who is Building Rust Utils?

Rust Utils is developed by Gabriel Cruz, a software engineer specializing in Rust, C, and Python, with a strong background in distributed systems. Based in São Carlos, Brazil, he has worked extensively on performance-focused networking tools and cryptographic implementations.

His previous work includes building nesquic, a Netcat-like tool for QUIC, and conducting deep technical research on Rust’s async mechanisms. He has also contributed to various open-source projects involving low-level programming, security, and performance optimisations.

With Rust Utils, Gabriel is finalizing a critical piece of Qubic’s infrastructure, ensuring the network’s protocol is fast, secure, and built for long-term scalability.

Why It Matters for Qubic

Qubic is evolving, but for mass adoption, the protocol must be rock-solid. Rust Utils plays a critical role in making that happen.

• Stronger Security → Rust eliminates entire classes of bugs common in lower-level languages.

• Better Performance → Faster networking means quicker transactions, more efficient mining pools, and reduced latency.

• Easier Development → With Rust Utils, developers have a ready-to-use framework for building on Qubic - whether it’s miners, smart contracts, or wallets.

• Interoperability → The modular design makes it possible to extend and improve the Qubic ecosystem without rewriting core components.

Simply put: Rust Utils is a fundamental building block for Qubic’s future.

What’s Next?

The heavy lifting is almost done. The last piece of work involves:

• Finalising the protocol implementation → Making sure every networking request works seamlessly.

• Testing and Optimisation → Stress-testing it under real-world conditions.

• Smart Contract Refinements → Possibly refactoring certain contracts for better efficiency and maintainability.

Once complete, Rust Utils will fully unlock a faster, more flexible, and more secure Qubic network.

Final Thoughts

Infrastructure matters. Qubic needs a stable, high-performance protocol, and Rust Utils delivers exactly that.

This project finalises critical pieces of the network, making Qubic easier to build on, faster to use, and more secure for the future. It’s a necessary step toward making Qubic a high-performance blockchain ecosystem.

Rust Utils is coming. And with it, Qubic moves one step closer to being unstoppable.
