A framework for building on-chain games on Solana using Ephemeral Rollups. MagicBlock allows game state to temporarily move to a dedicated SVM instance for high-frequency updates (sub-second ticks), then settle back to Solana mainnet. This enables real-time multiplayer games while maintaining Solana's composability and security.

Use the quick analogy first so the term is easier to reason about when you meet it in code, docs, or prompts.
Think of it as a tool or abstraction that removes friction from shipping on Solana.
Place the term inside its Solana layer so the definition is easier to reason about.
Anchor, local validators, explorers, SDKs, and testing workflows.
Turn the term from vocabulary into something operational for product and engineering work.
This term unlocks adjacent concepts quickly, so it works best when you treat it as a junction instead of an isolated definition.

The Solana Virtual Machine—the execution environment that runs on-chain programs. SVM loads SBF bytecode, provides syscalls for account access and cryptographic operations, enforces compute budgets, and manages memory. The SVM is being modularized (via the SVM API) to enable use in rollups and other environments outside the main Solana validator.
The ecosystem of on-chain games and gaming infrastructure on Solana. Key technologies: MagicBlock (ephemeral rollups for real-time games), Bolt (ECS framework), Solana Unity SDK (Unity integration), and session keys (for gasless UX). Solana's low fees and fast finality make it suitable for gaming where frequent state updates are needed.
These are the next concepts worth opening if you want this term to make more sense inside a real Solana workflow.

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.
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 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).
