Technique where applications access network hardware directly, bypassing the OS kernel's networking stack to eliminate syscall overhead and achieve microsecond-level latency. Firedancer uses kernel bypass (via XDP/AF_XDP or DPDK-style techniques) for its networking layer, enabling significantly higher packet throughput than Agave's userspace networking.
A from-scratch Solana validator client written in C by Jump Crypto. Firedancer aims for significant performance improvements through a tiled, zero-copy architecture and hardware-optimized networking. It provides client diversity—critical for network resilience—and targets 1M+ TPS. Frankendancer is the intermediate version running Firedancer's networking stack with the Agave execution engine.
Processing technique where multiple stages of a task execute in overlapping fashion, like an assembly line. Solana's validator pipeline processes transactions through fetch, SigVerify, banking, and broadcast stages simultaneously, achieving higher throughput than sequential processing. Essential to Solana's 400ms slot production.

A systems programming language emphasizing memory safety, zero-cost abstractions, and concurrency without a garbage collector. Rust uses an ownership model with borrow checking at compile time to prevent data races and null pointer bugs. It is the primary language for Solana program development (via Anchor or native solana-program crate) and the Agave validator client.
A statically typed superset of JavaScript that compiles to plain JavaScript. TypeScript adds type annotations, interfaces, generics, and enums to catch errors at compile time. It is the standard language for Solana client-side development—wallet adapters, dApp frontends, test suites, and SDK interactions (web3.js, Anchor client) are typically written in TypeScript.
The ubiquitous scripting language for web development, running in browsers and Node.js. JavaScript is dynamically typed and event-driven. Most Solana dApp frontends and scripts use JavaScript/TypeScript with libraries like @solana/web3.js. Node.js enables server-side JS for backend services, indexers, and bot development.
A JavaScript runtime built on Chrome's V8 engine that enables server-side JavaScript execution. Node.js uses an event-driven, non-blocking I/O model. In the Solana ecosystem, Node.js is used for: running Anchor tests (Mocha/Jest), backend services, transaction bots, indexers, and CLI tools. npm/yarn/pnpm manage JavaScript package dependencies.
