Memory-safe, high-performance systems programming
Rust is a systems programming language that guarantees memory safety without a garbage collector, giving it performance comparable to C or C++ without an entire category of memory-related bugs (use-after-free, buffer overflows) that plague lower-level languages. It's become a default choice for blockchain protocol development and other performance-critical infrastructure.
For code where a crash or a memory bug has real consequences a blockchain node, a high-throughput service Rust's compiler catches an entire class of production incidents before the code ever runs, at the cost of a steeper learning curve during development.
We reach for Rust for performance-critical services and blockchain-adjacent infrastructure where its safety guarantees and raw performance justify the additional development time over a higher-level language.
