The blockchain infrastructure layer is buzzing with innovation across different verticals. Scalability has been a major theme driving this innovation, unlocking utility and the next wave of growth. Over the past few years, the blockchain scalability landscape has evolved significantly, attracting hordes of developer and user activity. L2 rollups continue to show consistent growth, with adoption rising and activity hitting an all-time high. Indeed, Vitalik’s vision of a rollup-centric Ethereum roadmap is now in full swing. As the L2 market continues to mature toward its next phase, in order to unlock the next phase of growth, L2 rollups are beginning to map out their visions to assert supremacy in the rollup-dominated future.

The proliferation of rollups on Ethereum as the path to scaling blockchains today is a double-edged sword. While it bootstraps security and decentralization, deploying many “disconnected” rollups on Ethereum creates information asymmetry and fractures composability. In a bid to solve this, Optimism’s OP Stack is pioneering the path towards a highly interoperable network of blockchains by abstracting away the notion of singular chains and creating a unified web of chains, known as the Superchain. In this report, we explore the OP Stack and take a closer look at the Superchain thesis, as well as the possibilities it will bring to the Ethereum ecosystem.

In October 2022, Optimism Labs introduced the OP Stack — also known as optimism stack, a standardized, shared, and open-source development stack that powers the Optimism network and its ecosystem (i.e. a set of software). The Optimism collective describes it as a “modular, open-source blueprint for highly scalable, highly interoperable blockchains of all kinds.” The OP Stack is an evolving concept, designed to grow into suiting the needs of the evolving Optimism ecosystem.

Primarily, the OP Stack is focused around the creation of a shared, high-quality, and fully open-source system for creating new L2 blockchains. The main idea is to simplify the process of creating L2 blockchains. As such, the Optimism team has adopted a plug-and-play approach that allows the modification of components of the OP Stack to build novel L2 systems. Essentially, the OP Stack deconstructs all of the different components that go into building an L2 and packages them as separate modules. This flexibility enables developers to combine the most suitable modules to construct their own custom L2 that cater for either general-purpose or application-specific needs.

The current iteration of the OP Stack is Bedrock. Bedrock the first deployment of the OP stack, which provides the tools for launching optimistic rollup networks. It is a set of free and open-source modular components that work together to power Optimism. The Bedrock release introduces several major enhancements to the network and sets the stage for OP Superchain. The prime advantages of Bedrock over its predecessor include lower transaction fees (over 77% cheaper per transaction on average), shorter deposit times, improved proof of modularity, and improved node performance.

The Superchain concept was born out of a battle-tested scalability vision, premised on Optimism’s alignment with Ethereum’s values of decentralization and unification of all rollup architectures. With a clear picture of "how to architect a truly scalable blockchain," the OP team embarked on the journey to creating the Superchain. The ultimate goal is not merely to construct a single blockchain but to foster a comprehensive Digital Society that thrives on seamless and efficient interaction between different Op-chains.

“The Superchain seeks to integrate otherwise siloed L2s into a single interoperable and composable system.”

The Superchain conceptualizes a horizontally scalable network of chains (called OP Chains) built on top of the OP stack, which share security, a communication layer, and an open source technology stack. The Superchain will be built on the OP Stack codebase, a modular development stack for decentralized infrastructure. By harnessing the power of layer 2 rollups and a shared development stack, the Superchain can offer unprecedented levels of scalability and flexibility. This enables developers to build applications which target the Superchain as a whole, and abstract away the underlying chains the apps are running on.

The power of the OP Stack lies in its ability to distill each component of a Layer 2 into a standardized module. The individual chains on the Optimism Superchain are called OP chains. Unlike multi-chain architectures, these chains have a standardized architecture, and are intended to be used as interchangeable resources. The Superchain structure is intended to provide an interoperable environment for layer 2 networks to communicate and interact with one another. This inter-chain communication forms the bedrock for establishing an omnichain system that facilitates smooth cross-chain transactions.

At its core, the architecture consists of a shared base layer for DA, a shared bridge between the base layer and OP chains to ensure standardization of security, a cheap and flexible framework for the deployment of the OP chains, the OP chains and a cross-chain messaging protocol for the transfer of data and digital assets between OP chains. This structure makes the Superchain an ideal platform for developing decentralized applications that target multiple networks.

Upgrading Optimism to become a Superchain requires the application of a number of changes needed to create a initial Superchain that makes it possible to deploy and upgrade OP chains. The foremost change is to upgrade the Bedrock bridge to become an OP chain factory capable of deriving data from OP chains. Sequel to this, it is required to create a permissionless proof system to enable withdrawals, then the implementation of multiple sequencers to enable configurable sequencers for OP chains.

For the Superchain vision of a fully scalable blockchain to be realized, there are certain foreseeable issues that needs to be addressed within the Optimism Network and the OP stack. These include the reliance of withdrawal claims on a trusted set of chain attestors, slow cross-chain transactions, cross-chain transactions, and lack of scalability. In a bid to address these issues, a proposal of potential future enhancements have been made such as Multi-Proof Security design to replace the present trusted set of chain attestors, Synchronous cross-chain transactions, an alternative Data Availability layer to Ethereum (Plasma), and Multi-Chain dApp Frameworks. If all of these issues are addressed, it would enhance the possibility of building decentralized alternatives to even the most complex web2 applications.

The value proposition of the Superchain is about solving the several bottlenecks associated with traditional multi-chain architectures. Where each chain introduces a new security model, resulting in compounding systemic risk as new chains are added into the ecosystem, coupled with the cost of setting up new nodes. The Superchain enables horizontal scalability, hence solving these issues without creating additional blockchains. Instead, new layer 2 networks are built on an analogous base layer that enables homogenous security and relies on the same sequencer set. This solves the problems associated with multi-chain architectures.

The Superchain endgame is straightforward: a collective of Ethereum-aligned chains, interacting with one another over a shared infrastructure. The Superchain represents a major landmark in the platform’s development journey and is expected to become more decentralized as the underlying Bedrock infrastructure reaches its full potential. It is vital to note that the Superchain is currently just a concept and very much a work in progress, one in which the Optimism team describes as a “multi-year journey.”

As of now, it’s difficult to predict the exact future of Superchain, however, given the track record and capabilities of the Optimism team, the Superchain vision is expected to materialize as planned. As Superchain takes its first successful steps towards the future, the challenges faced by the Optimism team have proven to be instrumental in shaping the platform’s robustness and potential for widespread adoption. With a modular architecture and EVM Equivalence, Superchain is poised to offer a powerful and user-friendly ecosystem for developers and users alike.
