Race to Enhance Scalability: Comparision of OP Stack and ZK Stack

Table of Contents

Welcome to the ever-evolving world of blockchain technology, where the race to tackle Ethereum's scalability challenges is gaining momentum through Layer 2 solutions. In this dynamic landscape, two major contenders, OP Stack and ZK Stack, are at the forefront of innovation, each employing distinct approaches to enhance Ethereum's scalability

I. Layer 2 Scaling Solutions of the Top Two Technologies: Optimistic and Zero Knowledge

Both OP Stack and ZK Stack are innovative products aimed at enhancing Layer 2 scalability on the Ethereum network. While their ultimate goals are similar, they employ distinct approaches to achieve this feat, making the competition between the two projects particularly intriguing.

The competition between OP Stack and ZK Stack is fierce, with both projects garnering attention from developers and the blockchain community. The winner of this race will have a profound impact on Ethereum's future scalability, enabling faster and more cost-efficient transactions on the network.

II. Overview of OP Stack

1. What is OP Stack?

Developed and maintained by the Optimism Collective, OP Stack (Over Powered Stack) is designed with key principles: usability, simplicity, and scalability, enabling an open-source shared system to deploy new rollup networks.

The primary focus of OP Stack is to create a high-quality open-source platform for launching highly optimized rollup networks. This becomes increasingly crucial as the concept of the Superchain gains traction, requiring secure new networks to interact seamlessly within the proposed Superchain ecosystem. By adhering to shared standards, Optimism Collective aims to foster collaboration and avoid redundancy in the software development process, thus streamlining the deployment of Layer 2 blockchain.

Currently, in its Bedrock version, OP Stack provides developers with the necessary tools to launch highly optimized rollup networks. It has been carefully designed to support the Optimism Superchain, a network comprising interconnected Layer 2 solutions sharing security, communication layer, and a common development stack – the OP Stack. Bedrock empowers developers to rapidly create and deploy fully customizable rollup networks that are fully compatible with the Superchain ecosystem. However, it is important to note that the current Bedrock release lacks the flexibility for easy modifications, which would be essential to support future iterations of the OP Stack.

2. Features of OP Stack

One of the most noteworthy aspects of OP Stack is the groundbreaking concept it introduces – the "Open Garden." This concept allows OP chains to achieve cross-rollup atomic composability, as long as they voluntarily choose to participate in the same shared sequencing system. Essentially, it enables seamless collaboration between different chains in the ecosystem. For OP chains that do not wish to maintain their sequencing order, they have the option to use Optimism's shared sequencing mechanism with a certain fee, providing a revenue model for Optimism.

Looking ahead, the vision for OP Stack revolves around the concept of a unified Superchain, where all OP chains can fully interact with each other within the Optimism platform. By sharing modules within the OP Stack, developers can recycle and reuse code, making the entire system more robust and resistant to vulnerabilities and errors.

3. Strong Backing from Industry Giants

Soon after its launch, OP Stack received widespread support from prominent players in the Web3 space. Coinbase, a leading cryptocurrency exchange, announced its collaboration with OP Stack to build a multi-chain Layer 2 (L2) platform. The collaboration aims to upgrade the core networks Optimism, Base, and other L2s to establish an initial super-chain structure, enabling seamless transaction connections and categorization. As part of this collaboration, Base, built on OP Stack, provides enhanced scalability and security to support decentralized applications while maintaining full compatibility with the Ethereum Virtual Machine (EVM) at minimal costs, thereby facilitating developer platform growth.

4. Ethereum's Role

At the core of OP Stack, Ethereum serves as a specialized Data Availability (DA) layer, responsible for storing and securing data. Ethereum's Proof of Stake (PoS) consensus mechanism ensures the integrity and security of the data that OP Stack relies on.

OP Stack's layered architecture includes the Execution layer, which leverages the Ethereum Virtual Machine (EVM) to process transactions and effect state changes. The Derivative layer is responsible for fetching input data from the DA layer to record the state, ensuring smooth operation and interaction capabilities.

As the ecosystem expands, OP Stack remains committed to continuous improvement. The team plans to introduce a modular sequencing scheme to prepare for multiple rollup networks built with OP Stack, enhancing interaction capabilities and scalability. The Governance layer, consisting of governance tokens and multi-signature smart contracts, manages the OP Stack, including system configurations, upgrades, and decision-making processes.

III. Overview of ZK Stack

1. What is ZK Stack?

In an exciting leap for decentralized technology, ZK Stack has emerged as a revolutionary open-source modular framework designed to create customized Layer 2 (L2) and Layer 3 (L3) chains under ZK control, known as Hyperchains. Based on zkSync Era's code, this advanced platform provides unparalleled sovereignty, seamless connectivity, and super scalability, redefining the context of blockchain solutions.

2. Objectives of ZK Stack

The focus of ZK Stack lies in its key features, empowering creators with absolute autonomy to customize and shape every aspect of their chains. This framework operates under the fully permissive MIT/Apache open-source license, ensuring that developers can freely contribute to and utilize its capabilities as they see fit.

A central feature of ZK Stack is its emphasis on sovereignty and seamless connectivity. The Hyperchains built on this framework maintain their independence while relying on Ethereum L1 for security and operation. The connectivity of these Hyperchains is facilitated through a network of Hyperbridges, enabling reliable, low-latency, and cost-efficient interaction.

3. Outstanding Features of ZK Stack

Pioneering the realm of highly scalable unified liquidity networks is zkSync Era, playing the role of the leading Hyperchain. For developers seeking to combine their projects with existing protocols in the ecosystem, deploying their projects on zkSync Era proves to be a straightforward choice, with additional features like easy-to-access fast withdrawals.

However, ZK Stack offers an appealing alternative in specific use cases. Developers looking for tailored fit for their chain or those comfortable with asynchronous interaction within a broader ecosystem can leverage this framework's full potential. It serves diverse use cases, ranging from lightweight sequencing for gaming and social networks to low-latency ordering for exchange application chains like dYdX, and even private chains for enterprises seeking ecosystem connectivity while maintaining privacy.

The decision to build on ZK Stack stems from its inherent suitability for its future. Zero-knowledge technology unlocks unique superpowers beyond what traditional non-ZK solutions can achieve. The framework's design leverages low-gas calldata in its ZK-supporting architecture, ensuring a particularly user-friendly experience through Abstract Account Model.

Furthermore, ZK Stack achieves notable compression capabilities through ZK proofs, resulting in specific types of transactions, such as cheap fast upgrades, being up to 1,000 times cheaper than other aggregate platforms. Additionally, the framework provides low-cost expansion utility options through zkPorter accounts, catering to specific use cases with budget constraints.

4. Differences between ZK Stack and Other Scaling Approaches

The core philosophy of super scalability sets ZK Stack apart. By allowing developers to create sovereign Hyperchains without compromising interaction and composability, this framework promotes a non-fragmented liquidity network. The Hyperchains within this ecosystem can seamlessly transfer assets among themselves within minutes, all in an unreliable and cost-free manner, thanks to Hyperbridges.

Moreover, cross-chain asynchronous smart contract calls further enhance the seamless user experience, contributing to the overall flexibility of the decentralized ecosystem.

The competition between OP Stack and ZK Stack is not only fascinating but also crucial for the advancement of blockchain technology, as it seeks to address Ethereum's scalability concerns and pave the way for a more efficient and scalable decentralized future.
