Zero-Copy

A memory access pattern where data is read or manipulated directly from its original buffer location without allocating new memory or copying bytes. In Solana program development, zero-copy is used to access account data in-place from the runtime's memory-mapped byte slice, avoiding expensive heap allocations and Borsh deserialization overhead. Frameworks like Anchor (#[account(zero_copy)]) and Pinocchio use this pattern extensively to minimize compute unit consumption for large accounts.

Zero-Copy Deserialization

A technique for accessing on-chain account data directly from the underlying byte buffer without copying it into a new Rust struct, avoiding heap allocation and reducing compute unit usage. In Anchor, zero-copy is enabled via #[account(zero_copy)] on the account struct, which uses repr(C) layout and the AccountLoader type. Ideal for large accounts (>1KB) where Borsh deserialization would be expensive.

Borsh

Binary Object Representation Serializer for Hashing—the standard serialization format for Solana program data. Borsh produces deterministic, compact binary encodings with a fixed schema. It's used by Anchor for all account and instruction data serialization/deserialization. Borsh supports structs, enums, vectors, and other Rust types.

Serialização / Desserialização

Account Data

The byte array stored in an account that holds program-specific state. Data is typically serialized using Borsh and must be explicitly allocated at account creation. The maximum data size is 10MB. Programs are responsible for defining and managing their own data layout, including discriminators for type identification.

WebAssembly (WASM)

A portable binary instruction format designed as a compilation target for high-level languages, enabling near-native execution speed in web browsers and other environments. While Solana uses SBF (not WASM) for on-chain program execution, WASM is relevant to the ecosystem: some blockchain VMs (Polkadot, NEAR) use WASM, and Solana client-side tools may compile to WASM for browser-based dApps. Anchor IDL clients can run in WASM environments via @solana/web3.js.

Fundamentos de Programaçãocopy-on-write

Copy-on-Write

Memory optimization where data is shared between readers until a writer modifies it, at which point only the modified portion is copied. Solana's AccountsDB uses copy-on-write semantics — accounts are written to new AppendVec entries rather than modifying in place, enabling snapshot creation without pausing transaction processing.

Fundamentos de Programação

Rust

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.

TypeScript

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.

JavaScript

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.

Node.js

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.
