As custom Layer2 and Layer3 blockchains grow in popularity and adoption, the demand for powerful rollup frameworks sees impressive responses, including Arbitrum Orbit. Orbit stands out with features such as simplified Layer3 adoption, expansion to MultiVM, and chain clusters fostering true interoperability. Moreover, it has the backing of the broad Arbitrum network, recording a whopping $2.585B TVL. And, now that many promising Layer3s are built using Arbitrum Orbit, let’s highlight all the advantages of Arbitrum Orbit for application-specific rollup chains in all the niches– be it Web3 gaming, DeFi, RWA tokenisation, or general-purpose applications. 

Arbitrum Orbit Explained 

Arbitrum Orbit is an Optimistic rollup-based framework designed to empower web3 businesses by allowing them to build custom, use case-specific Layer2 or Layer3 chains in a purely permissionless way. Orbit leverages the Arbitrum Nitro Tech stack that powers all the Arbitrum Orbit chains with unparalleled scalability, advanced compression, full EVM compatibility, and cross-chain interoperability (rolling out soon). For a clear understanding, we can think of Arbitrum Orbit as Nitro stack’s deployable and configurable instances that together form an ecosystem of independent chains. 

With Arbitrum Orbit, developers or enterprises have the choice to build a Layer2 or Layer3. Meaning, they get the flexibility to choose Ethereum as their settlement layer or any of Arbitrum’s L2 chains, for example- Arbitrum One. Plus, the ease of customizability allows for personalisation of the chain as per project-specific requirements. All the essential components of a rollup chain, including precompiles, transaction throughput, governance, privacy, sequencer, and data availability (DA) layers, can be configured effortlessly, plus the customisation possibilities are endless. 

Also, Arbitrum Orbit is often confused with application-specific blockchains or “appchains”. Here, the idea should be clear that an Orbit chain can work as an appchain, but they do more than just powering a single application, such as supporting smart contracts on one or more apps, an ecosystem of apps or absolutely no apps. Additionally, your dApps can utilise multiple L2/L3 Orbit chains to enable high availability and advanced features in its ecosystem. 

Key advantages Arbitrum Orbit offers for Layer3s

Customizable, dedicated throughout:

High-traction dApps, such as gaming and crypto trading platforms, demand massive scalability and they often need to adjust their ecosystem’s throughput capacity as per the traffic volume. With Orbit chains, your dApp is managed on its own independent chain so that you don’t need to compete with other dApps for storage or computation resources. This helps chains overcome scalability limitations and get a separate opt-in environment to ensure the high availability of all types of resources. 

EVM+ Compatibility of Stylus: 

L2/L3 Orbit chains benefit from the multiVM support features that Stylus introduces. This means developers can write smart contracts in their preferred languages, be it Rust, C++, C, or Solidity, while still maintaining full compatibility. Basically, any language that compiles to Arbitrum’s WASM VM is supported for smart contract programming. After the giga-update, Stylus has been optimised to offer 2-4x cheaper fees, compression of contract sizes, broader tooling support, reliable safety, and new host I/Os. 

Unparalleled customisation in all aspects:

Layer3s building with Arbitrum Orbit can customise various aspects of their network. For example, they can introduce a custom ERC-20 token as their chain’s native token, define their own governance protocol, or modify the chain logic (like execution, settlement, DA, etc) to meet specific needs. All these are possible while retaining the high level of security from Ethereum through DAO-governed L2s of Arbitrum. 

Predictable gas cost:

Predictability of transactions/gas cost is important for a lot of dApps that want to forecast their business cost and thereby implement cost-prohibitive strategies such as subsidisation of transaction fees. Doing this is easier for Orbit chains as they do not share a common ecosystem and remain isolated from underlying Layer1 like Ethereum or Arbitrum L2s. Managing an ecosystem of your own means your dApp won’t get affected by other dApp’s on-chain activity, which makes way for more reliable gas fees for dApp users. 

Broad Data availability (DA) options:

Arbitrum Orbit supports broad data availability choices, enabling L3s to build their chain as an Arbitrum rollup or Arbitrum AnyTrust chain. Rollups allow for the use of Ethereum Layer 1 as the DA layer, while AnyTrust leverages a data availability committee (DAC) for off-chain storage of raw transaction data, offering users extremely cheaper gas costs. On top of that, Orbit chains can use third-party DA layers such as Celestia for off-chain data availability. The ultimate decision depends upon your project’s requirements. 

Btw, you can launch your fully functioning Arbitrum Orbit L3 devNet on Zeeve RaaS in just a few clicks. Here, you have the options for DAC in the Arbitrum AnyTrust chain and off-chain DA of Celestia, NEAR, Avail, and Eigen. 

Let’s get back to the discussion. We were on the advantages of Orbit chains, and here’s the next one. 

Quick launch for faster time-to-market: 

Having witnessed the rising popularity of the low-code approach to launching rollups, Arbitrum Orbit allows developers to use the Orbit chain deployment portal or choose from a range of Rollups–as-a-Service (RaaS) providers that guarantee the quick launch of your Orbit chain through their low-code deployment platforms, pluggable integrations, and innovative developer tools. Hence, the time to market becomes quite fast, which also lowers the overall cost. 

Robust security guarantee:

With Ethereum’s inherited security and Arbitrum Nitro, Arbitrum continues to keep its commitment to powering the most Layer2s across diverse industries. L3s can use this same powerful and mature technology stack to maintain robust security on their chain. 

Flexible technology stack: 

Flexibility in Arbitrum Orbit stack refers to the Layer3’s ability to choosing to build between L2 rollup, AnyTrust chain, or a Layer3 chain. However, there are crucial parameters for making the right decision. For example, Layer2 rollups are ideal for use cases that prioritize security and reasonable scalability the most. Rollups allow them to inherit security from Layer1 and meanwhile ensure massive scalability through off-chain computation where cost is much lesser than Layer1. Speaking about Layer3s, this is good for enabling scalability and low computation cost, however security here cannot be unmatched as Layer1. Likewise, AnyTrust is preferred when your chain wants to maintain data privacy through storage of data off-chain and its on-demand release. Security in DAC is based on assumption, which again introduces slight security trade-offs.

Permissioning feature:

Orbit chains have the flexibility to either add permissioned access to their ecosystem or keep it open to everyone, just like Ethereum. Meaning that, you can restrict smart contract deployment for your chain so that only your dApps can utilize the chain or make it permissionless, depending on the level of privacy you seek. 

Support for rollups modularity:

Arbitrum Orbit significantly focuses on modularity; hence, the protocol allows for seamless integration of alternative rollup components into Orbit and Arbitrum Layer2 chains. For example, you can integrate an off-chain DA layer, use a decentralized sequencer, a wallet, and an explorer with distinct features—everything is on you.

Freedom to use execution environments:

Different Arbitrum chains can experiment with full or partial restriction in their execution environment. For example, Orbit chains optimize their project by restricting some of the smart contract functionalities despite the EVM-compatibility of Arbitrum chains. 

Independent product roadmap: 

Orbit makes it possible to separate your L3 chain’s roadmap from that of Layer1 Ethereum or Arbitrum L2s. This means if you want to introduce cutting-edge features such as Account Abstraction (AA) on your network, you can accomplish this even when the feature is not yet enabled on the base chain Arbitrum public chains. 

Interoperability with Chain clusters: 

Although Orbit chains exist within an ecosystem of interconnected L2 or L3s, natively, interoperability between them still seems a heavy lifting. To solve this, Arbitrum has introduced chain clusters, which are essentially a communication layer to enable fast cross-chain communication token/resources transfers across standalone layer 2 and layer 3s. The idea of this chain cluster is new; thus, it might see a lot of changes, but it has been seen as a component that can enable true interoperability for Arbitrum.
