Binance – The rollups-as-a-Service Primer

The Binance Research primer on Binance's rollups-as-a-Service (RaaS) discusses the importance of rollups as Ethereum Layer-2 scaling solutions. Rollups are the main platforms for carrying out activities outside of the Layer-1 of Ethereum. There are two types of rollup solutions available: optimistic and zero-knowledge (zk). Recently, several major rollup solutions have emerged, allowing developers to launch their own rollups using their technologies. Some examples include Arbitrum's Orbit chains, Optimism's OP Stack chains, and zkSync's Hyperchains. RaaS providers are the next step in the ecosystem as they assist users in deploying and managing their own rollups. These providers offer a range of solutions and services, such as rollup management and no-code deployment, to make the process easier. When developers are deciding where to deploy their decentralized applications (dApps), they have various options, including existing Layer-1s, Layer-2s, creating their own appchains, or launching a rollup. While each option has its own advantages and considerations, launching a rollup with the help of RaaS providers may offer a balance between customization, performance, and effort. The introduction highlights some notable players in the RaaS space. Conduit has been involved in launching OP Stack and Arbitrum Orbit rollups, while Caldera focuses on optimistic rollups. AltLayer introduces disposable app-specific rollups called Flash Layers, and Gelato offers RaaS for both zero-knowledge and optimistic rollups. Additionally, Lumoz focuses exclusively on zero-knowledge rollups and brings an interesting hybrid consensus mechanism to the table.
