An elliptic curve designed by Daniel Bernstein for efficient Diffie-Hellman key exchange. It operates on a Montgomery curve over a 255-bit prime field, offering 128-bit security. Solana uses the related Edwards form (Ed25519) for transaction signatures. Curve25519 is favored for its speed, constant-time implementation, and resistance to timing attacks.
The process of converting plaintext data into ciphertext that can only be read with the correct decryption key. Symmetric encryption (AES) uses one key for both operations. Asymmetric encryption (RSA, ECIES) uses public/private key pairs. On Solana, encryption is used in confidential transfers (Twisted ElGamal), off-chain communication, and wallet security.
A cryptographic system using mathematically linked key pairs: a public key (shared freely) and a private key (kept secret). Used for digital signatures (sender signs with private key, anyone verifies with public key) and encryption (encrypt with public key, decrypt with private key). Solana uses Ed25519 for signatures and Curve25519/Ristretto255 for encryption.

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.
