RsNano V1.0 Release Announcement

We’re thrilled to announce the release of RsNano V1.0, the first official release of the Rust port of the original Nano node! 🎉

What is RsNano?

RsNano is a complete reimplementation of the Nano node, originally written in C++, now fully ported to Rust. Started on May 10, 2021, as a hobby project by Gustav Schauwecker, RsNano has grown into a robust, production-ready node after over 4 years, 7,000+ commits, and 100,000 lines of code. The entire codebase is now 100% Rust, bringing enhanced security, modularity, and testability to the Nano ecosystem.

Why RsNano?

RsNano strengthens the Nano network by:

• Increasing network security: Memory-safe code reduces vulnerabilities.
• Decentralizing development: Diversifying the tech stack for broader participation.
• Learning and innovation: A platform to explore Nano’s internals.
• Having fun: Built with passion for coding and the Nano ecosystem!

Why Rust?

Rust offers performance comparable to C++ but with compile-time guarantees for memory safety and thread safety, eliminating entire classes of bugs like:

• Buffer overflows
• Dangling pointers
• Use-after-free errors
• Null pointer dereferences

Rust’s modern design also simplifies multi-threaded programming, reduces bugs (like the ~70% of Microsoft’s bugs tied to memory safety), and makes refactoring easier. By using Rust, RsNano attracts a new wave of developers, fostering decentralized development and fresh contributions to the Nano community.

Journey to V1.0

What began as a fun side project evolved into a full-time endeavor. The porting process was live-streamed on YouTube, offering transparency and community engagement. Post-porting efforts focused on:

• Enhancing unit tests for reliability
• Improving code modularity and readability for future maintainability

What’s inside V1.0?

RsNano V1.0 is compatible with nano_node V28.1, but it only supports LMDB as the dababase backend. The database file is compatible too, so it is possible, although not recommended, to reuse an existing database file from nano_node.

For running it with docker, just execute:

docker run -p 7075:7075 -v ~/Nano:/root/Nano simpago/rsnano:V1.0 --network=live node run

More options for building or running the node can be found in the README

As this is the first release, please consider it as bleeding edge and please be aware that it may still contain issues.

Thank You, Nano Community!

A huge thank you to the Nano community for their unwavering support and generous donations over the years. Your encouragement made RsNano V1.0 possible!

Special thanks to

• Rui (Fiono11) for porting many different parts (for example the whole RPC-module!) and for the many insightful discussions about Nano’s protocol
• Luxbe for creating the rsnano.com website
• Bob (gr0vity-dev) for testing RsNano
• ArTombado for being the first supporter and for contributing fixes to the RPC module
• stjet from the banano community for contributing to the RPC module

What’s Next?

RsNano V1.0 marks a major milestone, but the journey continues. We’re excited to keep improving the node, welcoming new contributors, and strengthening the Nano network.
