He explains how Rust's memory safety, strong type system, and lack of garbage collection made it a good fit for BPF and virtual-machine development, while his Haskell background influenced Solana's design philosophy of thinking functionally but coding with ownership in mind. He details use of algebraic data types, the 'wincode' zero-copy encoder built on the bincode format, #[repr(C)] for precise memory layouts, and advice for Haskell engineers moving into Rust systems work, including a mention of the Alpenglow consensus protocol and its recently completed 50,000 SOL bug bounty. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### Why did Solana's founders choose Rust instead of Haskell or C for the blockchain runtime? Rust offered memory safety without garbage collection plus a strong type system, while Haskell's ecosystem lacked the maturity needed for a high-performance runtime and C's memory bugs were seen as too costly to productivity. Solana's cofounders had experience with both C and Haskell but found Rust's learning curve smooth given that background, with LLVM familiarity as a safety net against compiler immaturity. _Anyone weighing Rust against Haskell or C for a systems project can compare real production tradeoffs on daily.dev._ ### What is wincode in Solana's Rust codebase? Wincode is a zero-cost encoder/decoder built by the Solana team that implements the bincode binary format while using Google's ZeroCopy to minimize memory allocations. It was created to compress network messages into a compact binary format for bandwidth efficiency while keeping the interface easy to work with through algebraic data types, and its code is published at docs.rs. _Developers building low-allocation binary serialization in Rust can track tools like wincode on daily.dev._ ### How does Rust handle memory-safety issues when compiling to BPF for blockchain virtual machines? Rust's memory safety guarantees mean that once code compiles for BPF, it generally works correctly, unlike C where memory errors surface as obscure runtime errors in the BPF interpreter. Developers still need to use no_std for embedded constraints, manage stack usage carefully, and rely on #[repr(C)] to define precise memory layouts at the interface between the VM and runtime. _Engineers targeting constrained VMs like BPF can weigh Rust's safety tradeoffs against C on daily.dev._ ## Similar posts on daily.dev - [Why I Chose Rust for 0xInsider](https://daily.dev/posts/why-i-chose-rust-for-0xinsider-bzitxczjz) · Trevor Lasn · 21 upvotes · 6 comments - [Rust at the Core: Accelerating Polyglot SDK Development by Spencer Judge at QCon SF 2025](https://daily.dev/posts/rust-at-the-core-accelerating-polyglot-sdk-development-by-spencer-judge-at-qcon-sf-2025-uau5c7a49) · InfoQ · 2 upvotes · 0 comments --- Tags: [#rust](https://daily.dev/tags/rust), [#blockchain](https://daily.dev/tags/blockchain), [#haskell](https://daily.dev/tags/haskell), [#solana](https://daily.dev/tags/solana), [#language-design](https://daily.dev/tags/language-design) [View this post on daily.dev](https://daily.dev/posts/rust-haskell-and-the-architecture-behind-solana-interview-with-greg-fitzgerald-o4a8fkohx) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Rust, Haskell, and the Architecture Behind Solana: Interview with Greg Fitzgerald","url":"https://daily.dev/posts/rust-haskell-and-the-architecture-behind-solana-interview-with-greg-fitzgerald-o4a8fkohx","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/rust-haskell-and-the-architecture-behind-solana-interview-with-greg-fitzgerald-o4a8fkohx"},"datePublished":"2026-08-31T21:46:23.063Z","dateModified":"2026-09-13T19:46:54.466Z","description":"Solana cofounder Greg Fitzgerald discusses why the team chose Rust over C and Haskell for building Solana's high-performance blockchain runtime.
