Navigating the world of zero-knowledge rollups can be daunting, especially with innovative solutions like zkSync, Starknet, and Scroll leading the charge. Each of these platforms offers unique features and benefits, making the choice of which one to use a critical decision for developers and users alike. In this article, we'll dive into the intricacies of these ZK-rollups, compare their capabilities, and help you make an informed decision.
ZK-Rollup Comparison GuideWhen evaluating zkSync, Starknet, and Scroll, it's essential to understand their core functionalities and how they address the scalability issues of blockchain networks. zkSync, developed by Matter Labs, focuses on providing a seamless user experience with low transaction fees and high throughput. Starknet, on the other hand, is built by StarkWare and emphasizes smart contract functionality and scalability. Scroll, a newer entrant, aims to combine the best features of both while ensuring compatibility with the Ethereum Virtual Machine (EVM).
For instance, if you're a developer looking to build decentralized applications (dApps) with complex smart contracts, Starknet might be your go-to choice. However, if your priority is to ensure low-cost transactions for your users, zkSync could be more suitable. ScanGram's API can help you integrate these solutions seamlessly, providing real-time data and analytics to optimize your dApp's performance.
Layer 2 Scaling SolutionsLayer 2 scaling solutions are designed to enhance the throughput and reduce the costs of blockchain transactions. zkSync, Starknet, and Scroll are all Layer 2 solutions that leverage zero-knowledge proofs to achieve these goals. By moving computations off-chain and only submitting proof of their validity to the main chain, these solutions significantly reduce the load on the Ethereum network.
Consider a scenario where a popular dApp experiences a surge in user activity. Without a Layer 2 solution, the increased demand could lead to network congestion and high gas fees. By integrating zkSync, Starknet, or Scroll, the dApp can handle the increased load more efficiently. ScanGram's integrations can further streamline this process by offering tools to monitor and manage these Layer 2 solutions effectively.
Zero-Knowledge Proofs ExplainedZero-knowledge proofs (ZKPs) are cryptographic methods that allow one party to prove to another that a statement is true without revealing any additional information. In the context of blockchain, ZKPs enable transactions to be verified without exposing the underlying data, thereby enhancing privacy and security.
For example, imagine you want to prove that you have enough funds to complete a transaction without revealing your actual account balance. ZKPs make this possible. zkSync, Starknet, and Scroll all utilize ZKPs but implement them differently. zkSync uses zk-SNARKs, Starknet employs STARKs, and Scroll combines both to leverage their respective strengths. ScanGram's API can help you navigate these differences by providing detailed insights and analytics on each platform's performance.
[Features]
Determining the best ZK-rollup depends on your specific needs and use cases. If your primary goal is to minimize transaction costs and maximize throughput, zkSync is an excellent choice. Its focus on user experience and efficiency makes it ideal for applications with high transaction volumes.
On the other hand, if smart contract functionality and scalability are your top priorities, Starknet's robust infrastructure and developer-friendly environment might be more appealing. For those seeking EVM compatibility and a blend of different ZKP methods, Scroll offers a compelling solution. Utilizing ScanGram's integrations can help you evaluate and compare these platforms based on real-time data and performance metrics.
How to Use
Blockchain throughput refers to the number of transactions a network can process per second. High throughput is crucial for scalability and user experience. zkSync, Starknet, and Scroll all aim to improve blockchain throughput using their respective ZK-rollup technologies.
For instance, zkSync has demonstrated the ability to process thousands of transactions per second, making it a strong contender for high-volume applications. Starknet's focus on smart contracts and scalability also translates to impressive throughput capabilities. Scroll, with its combined approach, aims to match and potentially exceed these performance metrics. By leveraging ScanGram's analytics, you can conduct a detailed throughput analysis and choose the platform that best meets your requirements.

Frequently Asked QuestionszkSync, Starknet, and Scroll are Layer 2 scaling solutions for Ethereum, using zk-Rollup technology to increase transaction speed and reduce gas fees. zkSync, launched in 2020, offers zkSync 2.0 with up to 20,000 TPS. Starknet, launched in 2021, provides a decentralized, permissionless STARK-powered zk-Rollup with around 9,000 TPS. Scroll, currently in testnet, aims to provide a zkEVM-based solution with full EVM compatibility.
How do these platforms differ in terms of technology and approach?zkSync uses zk-SNARKs (Succinct Non-Interactive Argument of Knowledge) for its rollup technology, while Starknet employs zk-STARKs (Scalable Transparent Argument of Knowledge), which offer better scalability and do not require a trusted setup. Scroll differentiates itself by focusing on zkEVM (Zero-Knowledge Ethereum Virtual Machine) compatibility, allowing it to run existing Ethereum smart contracts with minimal modifications.
Which platform has the most user-friendly interface and developer support?zkSync currently has the most user-friendly interface, with a wallet and a growing ecosystem of dApps. It also offers comprehensive developer documentation and support.
