Distributed computing pattern where identical copies of a state machine are maintained across multiple nodes. Each node processes the same sequence of inputs deterministically, producing identical outputs. Solana validators are state machines: given the same ledger of transactions, every validator produces the same account state.

State Machine Replication (state-machine-replication) Categoría: Fundamentos de Programación Definición: Distributed computing pattern where identical copies of a state machine are maintained across multiple nodes. Each node processes the same sequence of inputs deterministically, producing identical outputs. Solana validators are state machines: given the same ledger of transactions, every validator produces the same account state.

A node that participates in the Solana network by validating transactions, voting on blocks, and (when selected as leader) producing new blocks. Validators run the Agave, Firedancer, or Jito client software, require significant hardware (128+ GB RAM, high-core CPU, NVMe SSD), and earn rewards from inflation and transaction fees.
The property that given identical inputs and initial state, a program will always produce the exact same output and state transitions regardless of which machine executes it. Deterministic execution is foundational to blockchain consensus because every validator must independently arrive at the same result when processing transactions. Sources of non-determinism (floating point, random numbers, system time) must be eliminated or controlled in blockchain runtimes.
The TVU component that replays received blocks by re-executing all transactions against the bank state. Replay stage verifies that transaction results match the leader's claimed results, updates the bank, and generates Tower BFT votes for valid blocks. If a replayed block is invalid, the validator marks that fork as dead.

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.
