Optimistic rollups aim to solve Ethereum’s scalability challenges by moving transaction processing off-chain while still leveraging its security and finality. However, even among these faster Layer 2 solutions, developers and businesses must conduct due diligence to achieve lower costs, faster performance, and broader support for programming languages.

This is where Arbitrum stands out with its Nitro technology. Offering faster execution, significantly lower gas fees, and enhanced developer flexibility, Arbitrum Nitro addresses the limitations that traditional optimistic rollups face. In this guide, we'll explore Arbitrum and its Nitro technology, highlighting its benefits for developers and businesses, and how Quicknode simplifies the deployment of these rollups.

What is Arbitrum Nitro?

Arbitrum Nitro is the technology stack powering Arbitrum’s Layer 2 solutions. It provides a comprehensive toolkit for building and deploying scalable, efficient decentralized applications (dApps) while leveraging familiar tools and reducing gas fees.

Nitro consists of the following layers:

1. Base layer (Geth Core): Nitro uses the Go Ethereum (Geth) core for seamless EVM contract execution and state management, allowing developers to work with familiar Ethereum tools.

2. Middle layer (ArbOS): This custom layer manages key Layer 2 functions such as calldata compression, gas fee management, and bridging operations, making it easier and more efficient to run dApps.

3. Top layer (Node software): Based on Geth, this layer efficiently manages user requests and full node operations, allowing the node to process large volumes of Remote Procedure Call (RPC) requests smoothly, even during high traffic.

This structure is referred to as a "Geth Sandwich," where Geth forms the base and top layers, and ArbOS acts as the "filling" that manages specific Layer 2 features.

How Nitro Works

Here’s an overview of how Nitro sequences and processes transactions:

• Sequencing: The Sequencer orders transactions, compresses them, and posts the batch as calldata on Ethereum. Once these transactions are confirmed on Ethereum, they’re processed using the State Transition Function (STF).

• Execution: The STF is compiled into native machine code, enabling Nitro nodes to process transactions with maximum speed and efficiency.

• Settlement: After execution, the Layer 2 state is updated, and the batched transactions are submitted to Ethereum.

• Proving: In a dispute, two validators engage in an interactive call-and-response process, narrowing down their disagreement to a single computational step. This step is executed on Layer 1, proving which validator is correct.

Introduction to Arbitrum Orbit

Arbitrum Orbit is a permissionless framework for launching fully customizable, dedicated chains using Arbitrum technology. Orbit chains can be deployed as Layer 2 solutions that settle directly on Ethereum or as Layer 3 chains that settle on existing L2 chains like Arbitrum One.

With Orbit, developers and businesses can configure various components of their chain, including throughput, privacy settings, gas token usage, governance models, and data availability layers, offering limitless possibilities for customization.

Three Benefits of Using Arbitrum Orbit

While Arbitrum One and Arbitrum Nova are ideal for mainstream applications, some projects may require more control over their chain’s features, governance, and infrastructure.

Orbit chains allow projects to build their own AnyTrust or Rollup chains, giving them full control over their infrastructure.

Unlike Layer 2 public chains that share governance, Orbit chains can be fully customized to suit a project’s specific needs, all while leveraging Ethereum's security. Here are some other benefits of using Arbitration Orbit:

1. Customization and Flexibility

Arbitrum Orbit provides developers with unparalleled flexibility in designing and managing their own chains.

• Customizable Protocol Logic: Tailor settlement, execution, or governance protocols to specific needs while maintaining Ethereum’s security through Arbitrum's L2 chains.

• Flexible Technology Options: Choose between Rollup, AnyTrust, or custom stacks, optimizing for performance and decentralization.

• Permissioned access: Deploy contracts in an open, permissionless environment or restrict deployment to specific applications or users. This gives developers flexibility in managing the access and usage of their blockchain environment.

2. Improved Performance and Scalability

For developers building resource-intensive dApps, Arbitrum Orbit ensures dedicated throughput, providing high performance and consistent resource availability. This eliminates concerns about competing for computational and storage resources.

Additionally, Orbit chains offer stable and predictable gas prices by isolating your dApp’s transaction costs from external on-chain activities. This allows developers to deliver a smoother and more predictable user experience.

3. Simplified User Experience

Here are two features of Arbitrum that focus on making the dApp experience smoother and more user-friendly:

• Account abstraction: Simplifies user experience by allowing mechanisms like transaction fee subsidization, making dApps more accessible to users who may not have a deep understanding of blockchain technology.

• Custom gas token: Allows for the use of alternative ERC-20 tokens as gas fees, integrating with the dApp’s ecosystem and enhancing the overall user experience by aligning gas costs with the native economy of the application.

In addition to these benefits, developers gain access to all Nitro’s features additions, upgrades, and improvements, since it’s powered by the tech stack.

Now, let’s look at why developers should choose Arbitrum Nitro for dApp development

5 Reasons to Choose Arbitrum Nitro for dApp Development

From faster transaction execution to better user experiences and quick dispute resolution, Nitro offers a range of advanced benefits. Here's why Nitro might be ideal for developers and businesses building scalable dApps:

1. Faster Transaction Execution

A key challenge in designing a practical rollup system is balancing high-performance execution with the need to reliably prove execution results. Arbitrum Nitro resolves this by separating execution from proving. Transactions are executed quickly without waiting for fraud-proofing unless a dispute arises.

This approach allows Nitro to provide fast, efficient transaction processing, minimizing delays and improving overall performance—especially for high-frequency applications like DeFi, gaming, and other real-time dApps.

2. Lower Gas Fees

Layer 2 solutions can face delays due to batch processing and settling on Layer 1, leading to potential transaction failures and manual resubmissions. Nitro's flexible architecture leverages tried-and-tested libraries for calldata compression.

This reduces the cost of posting transaction batches while ensuring data integrity, making transactions more affordable and scalable for both developers and users.

3. Smoother User Experience

Arbitrum Nitro transactions receive near-instant confirmation, known as soft finality, within 1-2 seconds after being processed by the Sequencer. Nitro also retries failed transactions without requiring manual resubmissions.

This improves network reliability and reduces failed transactions, offering a smoother overall experience for end-users.

4. Better Developer Experience

Developers often face the challenge of modifying or rewriting existing Ethereum contracts when deploying on other platforms, causing delays and extra work. Arbitrum Nitro solves this by offering full EVM compatibility through its integration of the Geth codebase.

This allows Ethereum contracts to run seamlessly without modification, saving developers time and effort, and enabling faster deployment and smoother project transitions.

5. Quick Challenge Resolution

In traditional fraud-proof mechanisms, disputes require re-executing entire transactions or blocks, leading to longer resolution times and higher costs.

Arbitrum Nitro's interactive proving breaks disputes into smaller steps, re-executing only the disputed part. This speeds up dispute resolution, reduces costs, and enhances network security and performance.

Beyond Nitro: Introducing Arbitrum Stylus for Greater Flexibility

While Arbitrum Nitro already provides faster execution, lower gas fees, and an overall smoother experience, Arbitrum Stylus, the new upgrade, takes these benefits even further.

Stylus introduces a second virtual machine (WASM VM) alongside the traditional Ethereum Virtual Machine (EVM).

The WASM VM setup allows developers to write smart contracts in languages like Rust, C, and C++ rather than being limited to Solidity.

Here are some additional benefits that Stylus brings to the table:

• Cheaper execution: Lower gas fees for complex smart contracts through more efficient computation and memory usage.

• Enhanced security: WASM programs offer built-in reentrancy detection, improving contract safety by default.

• Interoperability: Solidity and WASM programs are fully composable, allowing seamless interaction between different languages.
