Rollups as a service

Rollups-as-a-service is the latest trend in the blockchain space. That’s because RaaS simplifies Layer2 deployment, empowering web3 enterprises and projects to build Rollups chains at significantly lower costs quickly. Also, rollup-as-a-service platforms do not require heavy infrastructure and extensive resources to launch Rollups; instead, they offer a quick build and deployment approach through low-code platforms.

As we know, the biggest trilemma for blockchains is the ‘scalability’. We have already witnessed the situation of the Crypto Kitties congestion crisis that occurred due to over 2-4 billion transactions occurring in a single day, which led to the freezing of 30,000 transactions. Now that the demand for innovative decentralized applications (dApps)is growing rapidly, this scalability issue of Layer-1 blockchains becomes a major barrier to adoption.  

That’s why Layer-2 scaling solutions– Rollups existed and they are now rising in demand. Knowing this, numerous web3 infrastructure providers have started offering Rollups-as-a-service, enabling seamless creation, deployment, and management of Layer2/Layer3 chains. Let’s dive deeper into the Rollups-as-a-service (Raas) concept to understand its core concept, types, working mechanism, benefits, use cases, and more. 

However, to understand Rollups-as-a-service, you must understand the concept of Layer-1 and Layer-2 blockchains and AppChains. So, if you want to learn about these concepts, read our all-inclusive guide below:

Briefing Rollups and Its Advantages 

Rollups are the innovative Layer2 scaling solution designed to tackle the scalability issues of Layer-1 blockchain networks, which guarantees a faster, cheaper, and highly sustainable blockchain ecosystem for dApps. Rollups work by processing the bulk of blockchain transactions on a separate, faster network (Layer-2s), bundling the transactions into a single rollup, and then porting the bundled transactions back on the main blockchain (Layer-1) at a minimal gas fee cost. 

Rollups as a service

This approach of computing transactions off-chain could be beneficial for a lot of web3 applications in many ways. For example, it increases the transaction throughput capacity of the parent chain, and provides a more economical and sustainable ecosystem for dApp development while maintaining a high degree of security and full decentralization on Layer-2 by inheriting the security from the main Layer-1 chain

Polygon CDK, OP Stack, ZkSync Era, and Arbitrum Orbit are the top rollup frameworks that support the development of custom rollup chains. However, you can also deploy your application on a rollup-powered public mainnet such as Polygon zkEVM or OP Mainnet. This is helpful for projects that do not want their own chain for customization and performance.

What is Rollups-as-a-Service (RaaS)?

Rollups-as-a-Service (RaaS) is a comprehensive stack that allows web3 enterprises and dApp projects to build, deploy, and maintain their customized, production-grade Rollup chains and AppRollups (application-specific Rollups) in a less complex and hassle-free way; usually within few clicks.

RaaS provides an abstraction layer over the complex, coding-based approach of launching Rollups using SDKs and frameworks. RaaS works similarly to software-as-a-service products that do not require users to manage complex hardware and software infrastructure for hosting services.

Similarly, rollup-as-a-service platforms  eliminate the heavy lifting of building AppRollups from scratch which mainly include writing logics, infrastructure management, or scaling the nodes. Instead, RaaS offers a dashboard-like platform with advanced pre-configured components for instant launch of custom Rollups without intensive engineering or gathering technical expertise.

Types of Rollups-as-a-Service (RaaS)

There are two main types of Rollups-as-a-Service — Optimistic rollups and ZK-Rollups that are widely adopted. Both these Rollups offer unique benefits, hence, enterprises can choose one that aligns perfectly with their project requirements. 

Optimistic RaaS refers to the stack that Layer-1, L2, and Appchains use to implement Optimistic Rollup on their blockchain ecosystem. Transactions in the case of Optimistic are processed on a separate Layer-2 network, and then batched transactions are submitted to Ethereum or Layer-1 mainnet, assuming that the transactions are valid. Here, two parties are involved– one that submits the rolled-up transaction on mainnet and another that submits fraud-proof for those transactions. Both these parties have their token staked on the main network. If any invalid transactions are spotted, a dispute resolution will be conducted using their tokens. However, the chances of invalid transactions are rare in Optimistic Rollup since it adopts a dual-validation model. Popular optimistic rollup stacks are OP Stack and Arbitrum Orbit.

ZK-Raas refers to a solution that allows the implementation of zkRollups for blockchains and AppChains. Unlike Optimistic, zkRollups does not offer a dispute resolution mechanism. Instead, it is based on advanced cryptography technology— Zero-Knowledge proofs. Within this model, the batches of rolled-up transactions include a cryptographic proof called SNARK ( Succinct Non-Interactive Argument of Knowledge ), which is undertaken and verified by contract deployed on the main L1 blockchain. This means that a validity proof of transactions must be submitted on the main network, making Rollups quicker and more efficient. Prominent zero-knowledge rollup stacks are Polygon CDK, StarkNet, and zkSync Era.

How Does Rollups-as-a-Service or RaaS Platform Work?

RaaS platforms offer a complete set of features that allows web3 developers to create and implement custom Rollups in a few simple steps. Following is a simplified overview of how Rollups-as-a-Service typically works:

  •  Projects onboarding: Web3 projects can quickly sign up with a RaaS platform and gain access to their complete stack of SDKs, templates, and plug-n-play tools.
  • Customization: Rollupus-as-a-service platform supports full customization of Rollups chains based on project’s specific needs. Customization can include adjusting the security parameters, increasing the transaction processing capacity, setting transaction fees, and modifying the performance standards.
  •  Integration of rollup components: To enable modularity in rollups, RaaS platforms allow for various integrations for data availability (DA)layer, sequencer, settlement layer, etc. Also, you can choose third-party explorers, wallets, account abstraction (AA), and a lot more.
  • Monitoring and Maintenance: RaaS platforms also offer monitoring and maintenance services to ensure the optimal performance and reliable security of the Rollup solution.
  • Scaling and upgrade: As the project expands, RaaS platforms allow the network p scale for handling higher traffic, process more transactions, and optimize its speed.

Here’s a graphical overview of how RaaS platforms work at a basic level:

How Web3 Projects Can Utilize Rollups-as-a-Service?

Web3 projects can leverage RaaS in the following main ways: 

Application to Layer-1 and Layer-2 Networks

Layer-1 blockchain networks are actively exploring Rollup solutions to improve scalability. These chains can utilize Rollups-as-a-service platforms for quick launch of their custom rollup chain without the heavy lifting of infrastructure management or setting up the components such as nodes, wallets, explorers, etc. Similarly to Layer-1, Layer-2 blockchains can also use RaaS to build and implement use case-specific rollup chains for higher scalability, performance, and customization. 

Alternative to Application-specific blockchains

As we know, AppChains or Application-Specific Blockchains are standalone blockchains that manage large dApps on their ecosystem instead of sharing infrastructure with multiple dApps. While AppChains are a great way to achieve scalability, their development requires significant cost, infrastructure management hassle, etc. dApps can instead launch Rollups for their network’s ecosystem using Rollups-as-a-service platforms with access to high-end developer tools, plugins, and ready-to-use frameworks. However, web3 projects should do a detailed analysis of whether they need Rollups or an AppChain ecosystem. The comparison can be done on various parameters such as TPS, decentralization, interoperability requirements, customization, and cost-effectiveness.  

Rollups implementation for existing web3 projects 

High-traction gaming and non-fungible token (NFT) projects that manage millions of active users may face scalability issues due to increasing network congestion and huge transaction processing. These projects can launch custom rollup chains and migrate from their existing infrastructure, achieving high transaction speed, congestion-free environment, and highly secure infrastructure. Again, launching Rollups-based chains becomes easy for NFT and gaming web3 projects with Rollups-as-a-service platforms with ready-to-use stack, tools, and Rollups SDKs.
