The IOTA Foundation aims to allow machines of all performance levels to contribute to the IOTA network, from microcontrollers to phones, web browsers, and servers.

Therefore, we are developing Bee as a modular collection of extendable crates, which expose foreign function interfaces (FFIs) for the next iteration of client libraries.


You can find details about future development plans in our roadmap.



Bee will be a central reference implementation for the most important data structures and algorithms. This implementation will be verified during a Request for Comments (RFC) process, and eventually certified.

By using this approach, we hope that improvements to core components will quickly propagate to all other client libraries, rather than having to fix each one individually.


We have chosen the Rust programming language for Bee because of its C/C++ like performance, and its strong memory safety guarantees. Learn more about Rust.
