Is Solana written in Rust?

Yes, Solana’s core components are written in Rust. Rust is arguably the most well-known performance programming language for which memory safety plays a key role in its design. Rust contributes to high-speed, secure, and efficient systems that actually fit quite well with the design goals Solana had in mind. Solana also supports C-based languages and provides an alternative development framework in Anchor for easier smart contract creation in Rust. By using Rust, Solana aims to assure that reliable transaction processing at speed is delivered because this is key to its high-throughput decentralized applications and blockchain solutions.
