## What Is Mantle?

Mantle is a modular Layer 2 blockchain designed to improve Ethereum's scalability without compromising decentralization or security.

Instead of processing every transaction directly on Ethereum, Mantle executes transactions on Layer 2 and periodically submits compressed transaction batches to Ethereum for final settlement. This significantly reduces gas fees while increasing throughput.

Unlike many traditional Layer 2 networks, Mantle separates blockchain responsibilities into specialized layers, allowing each component to scale independently and operate more efficiently.

## How Mantle Works

### Optimistic Rollups

Mantle processes transactions using Optimistic Rollups.

Transactions are executed on Layer 2, grouped into large batches, and submitted to Ethereum. Rather than verifying every transaction immediately, the protocol assumes submitted batches are valid unless challenged through fraud proofs.

This approach dramatically increases network capacity while preserving Ethereum's security guarantees.

### Sequencer

The Sequencer is responsible for:

- **collecting user transactions**
- **ordering transactions**
- **creating rollup batches**
- **submitting state updates to Ethereum.**

The Sequencer improves transaction confirmation speed before final settlement occurs on Layer 1.

## Modular Blockchain Architecture

Mantle is built around modular blockchain design.

Rather than having every node perform every blockchain function, responsibilities are distributed across specialized layers.

### Execution Layer

Mantle performs transaction execution on Layer 2, greatly reducing Ethereum congestion while increasing throughput.

### Settlement Layer

Ethereum remains responsible for final settlement, ensuring that all finalized transactions inherit Ethereum's security model.

### Consensus Layer

Consensus continues to rely on Ethereum, allowing Mantle to benefit from the security and decentralization of the Ethereum mainnet.

### Data Availability Layer

Instead of storing transaction data directly on Ethereum, Mantle uses EigenDA for decentralized data availability.

This significantly lowers storage costs while keeping transaction data accessible for verification and fraud-proof mechanisms.

## Key Technologies Behind Mantle

### EigenDA

EigenDA provides Mantle's decentralized Data Availability layer.

Rather than storing large amounts of transaction data directly on Ethereum, EigenDA maintains transaction data off-chain while publishing proofs to Ethereum.

This architecture offers several advantages:

- **lower transaction costs**
- **higher throughput**
- **scalable storage**
- **efficient fraud-proof verification**
- **reduced Layer 1 congestion.**

### Fraud Proofs

Mantle inherits the security model of Optimistic Rollups through fraud proofs.

During the challenge period, validators can verify submitted transaction batches and detect invalid state transitions. If fraudulent activity is identified, incorrect batches can be rejected before final settlement.

### Multi-Party Computation (MPC)

Mantle introduces Multi-Party Computation (MPC) nodes to improve block verification.

Independent MPC nodes verify the Sequencer's state transitions before final settlement, increasing confidence in transaction correctness and potentially reducing the traditional Optimistic Rollup challenge period.

### EVM Compatibility

Mantle is fully compatible with the Ethereum Virtual Machine.

Developers can deploy existing Solidity smart contracts without rewriting application logic, enabling straightforward migration from Ethereum and other EVM-compatible networks.

Supported developer tools include standard Ethereum wallets, RPC endpoints, Solidity contracts, and common Web3 development frameworks.

## Advantages of Mantle

- **Lower Transaction Fees:** By combining Optimistic Rollups with EigenDA, Mantle significantly reduces the amount of data posted directly to Ethereum, resulting in substantially lower gas costs compared to Ethereum Layer 1.
- **Higher Throughput:** Batch transaction execution allows Mantle to process significantly more transactions than Ethereum while maintaining low latency and efficient resource utilization.
- **Ethereum Security:** Although execution occurs on Layer 2, transaction settlement and consensus remain anchored to Ethereum, allowing Mantle to inherit the security of the Ethereum mainnet.
- **Developer-Friendly Infrastructure:** Because Mantle supports the existing Ethereum development ecosystem, developers can migrate decentralized applications with minimal modifications, reducing development complexity and deployment time.
- **Scalable Modular Design:** Separating execution, consensus, settlement, and data availability allows Mantle to optimize each layer independently, making the network more adaptable to future scaling improvements than traditional monolithic blockchains.

## Frequently Asked Questions

### What is Mantle?

Mantle is an Ethereum Layer 2 blockchain that uses Optimistic Rollups and modular blockchain architecture to improve scalability while maintaining Ethereum's security.

### How does Mantle work?

Mantle executes transactions on Layer 2, batches them using Optimistic Rollups, stores transaction data through EigenDA, and settles verified state updates on Ethereum.

### What makes Mantle different from other Layer 2 networks?

Mantle separates execution, settlement, consensus, and data availability into independent layers. This modular architecture improves scalability, reduces fees, and allows each component to evolve independently.

### Is Mantle EVM-compatible?

Yes. Mantle fully supports the Ethereum Virtual Machine, enabling developers to deploy Solidity smart contracts and migrate existing Ethereum applications with minimal changes.

### What is EigenDA in Mantle?

EigenDA is Mantle's decentralized Data Availability layer. It stores rollup transaction data outside Ethereum while keeping cryptographic proofs available for verification, helping reduce costs and improve network scalability.
