Arbitrum Orbit Mainnet goes online, entering the Layer2 RaaS game with a strong presence.

Arbitrum Launches Orbit Mainnet, Establishing Dominance in the Layer2 RaaS Arena.

Yesterday, the Arbitrum Foundation released a tweet with the caption “Tomorrow,” suggesting a significant announcement today. And today, according to BlockBeats, the Arbitrum “Orbit” mainnet is ready.

Arbitrum Orbit is a project launched earlier this year, where blockchain developers can utilize Arbitrum’s technology to launch their own Layer 2 or Layer 3 networks. Steven Goldfeder, CEO of Arbitrum’s parent company Offchain Labs, stated that these new Layer 3 networks were previously only running on the Arbitrum testnet.

According to Offchain Labs, Orbit allows developers to “create their own dedicated chains on Arbitrum One, Arbitrum Nova, Arbitrum Goerli, and Arbitrum Sepolia to fit one of Arbitrum’s Layer 2 or L2 chains.”

Orbit+Stylus+BoLD, Arbitrum’s “L3 Blueprint”

Orbit Plan was one of the first announcements made by the Arbitrum Foundation when it was established in March. It is designed to create and deploy L3 development frameworks on top of Arbitrum’s mainnet, where the transactions on these L3 will be settled through Arbitrum’s L2 (such as Arbitrum One or Nova).

In order to better utilize the Orbit chain, Arbitrum has introduced a series of technical solutions.

On June 22nd, Offchain Labs released the Arbitrum Orbit development tool to assist developers in easier development on the L3 blockchain Arbitrum Orbit and manage their own Arbitrum Rollup and AnyTrust chains. In addition, Offchain Labs provided a quick start guide and on-chain tools for Orbit DevNet.

In August, Arbitrum had a series of intensive updates. Early in the month, they released the new validation protocol Bounded Liquidity Delay (BoLD), which allows permissionless validation on Arbitrum to minimize the settlement state’s delay. Arbitrum has relied on Ethereum to confirm the accuracy of its state. Ed Felten, co-founder and Chief Scientist of Offchain Labs, stated that the introduction of BoLD would eliminate the risk of delay attacks in this process, enabling anyone to become a validator without worrying about fraudulent behavior.

On August 31st, Arbitrum launched the Arbitrum Stylus code and public testnet, allowing developers to build applications on the Arbitrum Nitro chain using traditional EVM tools and WASM-compatible languages like Rust, C, and C++. Additionally, Stylus significantly lowers Gas costs by improving computational, storage, and memory efficiency, and it supports new blockchain use cases such as alternative signature schemes, larger generative art libraries, C++ based games, and previously computationally intensive AI models.

Since the launch of Arbitrum Orbit, multiple projects have joined the Orbit Chain ecosystem.

On April 27th, AltLayer, an Ethereum scalability solution, announced support for Arbitrum Orbit, a Layer 3 blockchain, through their Rollups-as-a-Service (RaaS) solution. Users can launch any L3 application bound to Arbitrum within minutes using their no-code tool.

On September 5th, RaaS company Caldera announced the launch of their initial batch of Arbitrum Orbit chains. Three partners, Syndr, Sanko GameCorp, and Volatilis Technology, plan to launch production-grade mainnet Orbit chains through Caldera in the coming weeks.

On October 26th, Celestia became the first modular data availability (DA) network integrated with Arbitrum Orbit and the entire Nitro stack.

It is foreseeable that Orbit will transform Arbitrum into a settlement layer similar to Ethereum, adding more value to its core chain and enhancing the long-term scalability of the entire Arbitrum ecosystem.

Has the RaaS track become a red ocean?

In addition to Arbitrum, other leading L2 solutions such as Optimism, zkSync, Starknet, and Polygon have also introduced Stack frameworks, aiming to open-source core components and promote RaaS solutions to seize the strategic high ground in Layer 2 and even Layer 3.

The rollup solution OP Stack, developed by OP Mainnet (formerly Optimism), has taken the lead among various L2 solutions.

OP Stack builds Optimism’s L2 rollup to create a shared, interoperable, and collaborative L2 blockchain network. Builders can modify existing modules or create new ones to adapt to their needs. Ultimately, Optimism aims to have highly compatible L2 chains, known as OP chains, which will be part of a Superchain.

In June of this year, Optimism announced the mainnet upgrade Bedrock, the first official release version of OP Stack, representing a complete modular rewrite of Optimism’s rollup architecture. Today, Optimism’s flagship rollup is built on the modular OP Stack, and Bedrock not only represents an upgrade to Optimism’s rollup but also provides tools for launching an Optimism L2 rollup blockchain.

Aside from the OP ecosystem, the two giants in the zk track have made their breakthroughs.

On June 26th, the zkSync development team at Matter Labs announced the launch of ZK Stack, a modular open-source framework for building custom zkRollups. ZK Stack empowers developers with full autonomy, from choosing data availability modes to using their own token decentralization sequencer.

ZK Stack offers two key functionalities: sovereignty and seamless connectivity. Creators have full rights to the code and enjoy unrestricted autonomy to customize and shape various aspects of the zkRollup chain. These zkRollup chains operate independently, relying only on Ethereum L1 for liquidity and security, while cross-chain bridges facilitate interconnectivity for each chain, enabling trustless, fast, and cost-effective (low transaction fees) interoperability.

In addition, there is also zkSync hyperchains, which, like Arbitrum, has its eyes set on L3. The implementation of hyperchains uses a modular approach, providing developers with a superchain software development toolkit (SDK) framework where they can choose various components to build their own blockchain or develop their own components.

Turning to Starknet, on July 19, StarkWare co-founder Eli Ben-Sasson announced at the EthCC (Ethereum Community Conference) in Paris that Starknet is about to launch Starknet Appchains. Starknet Appchains offer customizability, decentralization, and other features. By creating Starknet Appchains, applications can provide users with improved throughput and enhanced user experience.

The Polygon team, widely recognized for its business development (BD) capabilities in the crypto sphere, has brought together Canto (previously based on Cosmos) and Manta (which traversed Polkadot and OP).

From the above overview, we can see that although the visions of these L2 solutions differ, their core lies in customization and application-specific chains. Overall, the technological development in the crypto industry has evolved from “one-click token issuance” to “one-click chain deployment.”

“Today, there are already many ready-to-use RaaS (Rollup as a Service) solutions in the market. I have also used another RaaS product called Conduit, which helped Zora launch their testnet and mainnet based on the OP Stack. After testing, I can confidently say that setting up an OP L2 test chain only requires a single click of the mouse.”

The multi-chain and multi-rollup landscape in the crypto world is definitely a inevitable trend, and the giants entering the RaaS race bring more possibilities for the future of on-chain ecosystems. With the guidance of these industry leaders, RaaS is gradually but clearly becoming a highly demanded new segment. Regardless of the technology or management approach adopted, the value of L3, superchains, and hyperscalability is evident and seems to point towards the ultimate ideal of infinite scalability.
