# Introduction

> Build high-performance games and applications on Solana with MagicBlock Engine and Ephemeral Rollups

# Welcome to MagicBlock Engine Examples

MagicBlock Engine is a scaling solution for performant, composable games and applications on Solana. This repository provides practical examples of how to integrate Ephemeral Rollups into your Solana programs.

## What are Ephemeral Rollups?

Ephemeral Rollups (ERs) are temporary, high-performance execution environments that run alongside the Solana base layer. They enable:

* **Low-latency transactions**: Execute transactions in milliseconds instead of seconds
* **Reduced costs**: Lower transaction fees for high-frequency operations
* **Seamless composability**: Accounts can move between base layer and Ephemeral Rollups
* **Automatic state sync**: Changes are committed back to Solana automatically

<Info>
  The Ephemeral Rollups are currently under testing. Reach out on [Discord](https://discord.com/invite/MBkdC3gxcv) to get access to the testing endpoint.

## Available examples

### Framework examples

* **[Anchor Counter](/examples/anchor-counter)** - Simple counter using Anchor framework
* **[Rust Counter](/examples/rust-counter)** - Native Rust implementation without frameworks
* **[Bolt Counter](/examples/bolt-counter)** - ECS-based counter using the Bolt framework
* **[Pinocchio Counter](/examples/pinocchio-counter)** - Lightweight counter with Pinocchio

### Advanced examples

* **[Crank Counter](/examples/crank-counter)** - Scheduled automatic execution with cranks
* **[Magic Actions](/examples/magic-actions)** - Trigger base chain actions from Ephemeral Rollups
* **[Session Keys](/examples/session-keys)** - Gasless transactions with delegated signing
* **[Token Transfer](/examples/token-transfer)** - SPL token operations in Ephemeral Rollups
* **[Roll Dice](/examples/roll-dice)** - VRF integration for randomness

## How it works

The typical workflow for using Ephemeral Rollups follows three steps:

<Steps>
  <Step title="Delegate accounts">
    Transfer account ownership to the delegation program using CPI calls in your Solana program.
  </Step>

  <Step title="Execute transactions">
    Run transactions against delegated accounts in the Ephemeral Rollup with millisecond latency.
  </Step>

  <Step title="Commit or undelegate">
    Sync state changes back to Solana either automatically, manually, or when undelegating.
  </Step>
</Steps>
