Frequently asked questions (FAQs)

How do ZK rollups work?

A generalized mode of functioning looks more or less like this:
  • Batch collection stage, where ZK rollups assemble transactions in batches.
  • Off-chain transaction computation, validation, data transfer, and smart contract operations.
  • Once the batch is processed, ZK rollups produce cryptographic proofs attesting the validity of bundled transactions.
  • Submission to the main Ethereum network.
  • Main chain nodes verify the submitted proof.
  • As soon as blockchain verifies and accepts the proof, the transactions within the batch get finalized.

What features do ZK rollups offer?

By bundling multiple transactions into a single transaction and validating them through zero-knowledge proofs, ZK rollups enhance efficiency, reduce costs, and improve transaction speeds.

zkEVMs can be seen as upgraded versions of zkRollups, specifically designed to be compatible with the Ethereum Virtual Machine (EVM). While zkRollups reduce the amount of computing load on the Ethereum mainnet by compressing transactions, zkEVMs go one step further by computing smart contract operations off-chain in addition to the transaction processing.

Typically, zkEVMs build their own virtual machines to handle smart contract operations off-chain. The designs of these virtual machines differ based on several variables, including the type of zk proofs and ZK rollup infrastructure that supports them. That is, existing zkEVMs operate on a spectrum of high to low compatibility with Ethereum, introducing trade-offs in terms of proof generation time, gas costs, and other factors. As a result, certain tasks may be better suited to specific ZK rollups and zkEVMs than others. Let's explore the unique features and use cases of four major ZK rollup solutions: zkSync, Polygon zkEVM, Scroll zkEVM, and StarkNet.

Note that the following design features may soon be altered due to the ongoing R&D.

Features: Offers high Ethereum compatibility, a robust developer toolkit, and account abstraction for improved user and developer experience. It's gas-efficient, providing lower transaction fees and strong security with zero-knowledge proofs.
Use cases: Ideal for general-purpose dApps that require Ethereum compatibility and scalability. It's well-suited for projects seeking a balance between efficiency, security, and cost-effectiveness.

Polygon zkEVM
Features: Integrates seamlessly with the existing Polygon ecosystem. It supports almost all existing Ethereum smart contracts, combining the scalability of ZK rollups with the robustness of Polygon.
Use cases: Best for existing projects on Polygon needing scalability solutions, and new projects that prioritize compatibility and ecosystem support. It's attractive for those looking for an established network with scalability options.

Features: Known for its scalability and high transaction throughput. It utilizes Cairo, a powerful language for writing zero-knowledge proofs, focusing on security and privacy. However, StarkNet is the least EVM-compatible ZK rollup.
Use cases: Suitable for applications that demand high scalability, advanced cryptographic features, and data privacy. It's a go-to for projects that need advanced security and cryptographic capabilities.

Scroll zkEVM
Features: Focuses on EVM compatibility with an emphasis on developer experience and can be used to support any type of Ethereum application. It combines the benefits of ZK proofs with a user-friendly approach while offering two unique features: decentralized proving and low cost of proving.
Use cases: Ideal for Ethereum projects seeking scalability without significant code alterations. It appeals to new projects that value ease of development alongside scalability benefits.

Each ZK rollup brings unique strengths to the table, catering to different needs within the blockchain ecosystem. Whether you prioritize ease of development, compatibility with existing systems, transaction efficiency, or advanced security features, there's a ZK rollup solution that fits your project's needs.

What are the shortcomings of ZK rollups?

We’d first note that the following disadvantages may soon be addressed or mitigated due to the ongoing R&D and ZK rollups’ version updates. Today, the major challenges are:
  • Engineering-related complexity, as to build ZK rollups, developers are to have a good knowledge of cryptographic techniques. Thus, a limited number of experts can handle it effectively.
  • ZK rollup management and updates can pose certain challenges, as it requires wide user consensus.
  • Some ZK rollups support limited smart contract types. Meaning, certain apps relying on sophisticated smart contract functionality might not be able to use some features while relying on ZK rollups.
  • Due to the level of privacy provided by ZK proofs, some jurisdictions may imply potential regulatory scrutiny, leading to extra compliance requirements.
  • Withdrawal time concerns arise, as submission of validity proofs to the Ethereum mainnet extends waiting for the user, which can be a problem when it’s critical to access funds instantly.

How to choose the right ZK rollup?

While choosing the right ZK rollup, consider the following key factors:
  • Proven and tested-out security features audited by trusted external experts and communities
  • Advanced scalability, maximum throughput, suitable transaction confirmation times
  • High level of decentralization is preferable for consistently distributed and censorship-resistant networks
  • Solid privacy should be provided with zero-knowledge proofs that sit well with your security requirements
  • Seamless compatibility with other layer-2 platforms and the Ethereum network
  • Availability of documentation and developer community support
  • Adequate transaction fees and gas costs
  • Consistent smart contract execution support in case your apps or projects rely on smart contract functionality
  • Types of tokens supported by the ZK rollup should be relevant to your specific use cases
  • Adoption level, active community that ensures continuous ZK rollup development, updates, and user support

What is the promise behind ZK rollups?

The future of ZK rollups looks bright, given the advancements in zero-knowledge tech, EVM, and universal app compatibility. Enhanced privacy and low transaction costs make ZK rollups a go-to option for layer-2 scaling.
