The Anchor macro applied to structs to define on-chain account data layouts. `#[account]` auto-derives Borsh serialization, adds an 8-byte discriminator prefix (SHA-256 of 'account:<Name>'), and implements space calculation. Optional attributes: `#[account(zero_copy)]` for zero-copy deserialization of large accounts.

The most popular framework for building Solana programs in Rust. Anchor provides macros (#[program], #[account], #[derive(Accounts)]) that auto-generate boilerplate for account validation, serialization, discriminators, and error handling. It includes a CLI (anchor init/build/test/deploy), IDL generation, and TypeScript client generation. Reduces program code by ~80% compared to native development.
An 8-byte identifier prepended to account data and instruction data to distinguish types. Anchor computes it as the first 8 bytes of `sha256('account:<AccountName>')` for accounts and `sha256('global:<function_name>')` for instructions. Discriminators prevent type cosplay attacks by ensuring data is deserialized as the correct type.
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.

Anchor CLI commands for project lifecycle. `anchor init <name>` scaffolds a new project (program, tests, Anchor.toml). `anchor build` compiles to SBF and generates the IDL. `anchor test` builds, starts a local validator, deploys, and runs Mocha/Jest tests. `anchor deploy` deploys to the configured cluster. `anchor verify` checks deployed bytecode.
A major release (March 2025) of the Anchor framework introducing custom discriminators (overriding the default 8-byte discriminator to save transaction space), LazyAccount for on-demand deserialization to reduce compute costs, and stack memory optimizations for init constraints. Positioned as a major milestone on the roadmap toward v1.0.

The Anchor macro that defines the accounts struct for an instruction. Each field specifies an account with validation constraints. Account types include: `Account<'info, T>` (deserialized), `Signer<'info>` (must sign), `Program<'info, T>` (program reference), `SystemAccount<'info>`, and `UncheckedAccount<'info>` (no validation, use carefully).
Declarative validation rules on Anchor account fields. Key constraints: `#[account(mut)]` (writable), `#[account(init, payer=x, space=n)]` (create), `#[account(seeds=[...], bump)]` (PDA validation), `#[account(has_one=field)]` (field equality), `#[account(constraint = expr)]` (custom boolean), `#[account(close=target)]` (close and reclaim rent).
Anchor's error handling system. `#[error_code]` defines an enum of custom errors (auto-numbered from 6000). `require!(condition, ErrorCode)` and `require_keys_eq!()` macros provide concise validation. Errors include the program name and error name in logs. Custom errors return in the transaction metadata and can be parsed by clients via the IDL.
