What is EVM?
The Ethereum Virtual Machine (EVM) is the core engine of the Ethereum blockchain, acting as a decentralized computing platform. It supports cross-chain compatibility and executes smart contracts.
The EVM provides the infrastructure for decentralized applications (DApps), enabling the creation of ERC-20 tokens, NFTs, decentralized exchanges, and various other applications.
What is Zero-Knowledge Proof (zkRollup)?
Zero-Knowledge Proof (ZKP) is a cryptographic method that allows one party to prove that a piece of information is true without revealing the actual data. Essentially, the verifier only knows whether the statement is true, without being able to see the specific details of the information.
In the context of blockchain, ZKP enhances privacy and security. For example, it can validate transactions or contracts without disclosing sensitive data. This technology is a key tool for ensuring privacy on public blockchains, especially when information needs to remain confidential or when proprietary data is used to trigger smart contracts.
What is zkEVM?
zkEVM (Zero-Knowledge Ethereum Virtual Machine) combines the Ethereum Virtual Machine (EVM) with Zero-Knowledge Proof technology. It allows Ethereum smart contracts to be executed while ensuring the correctness of each action using ZKP, without exposing the underlying details.
zkEVM is part of Ethereum’s Layer 2 scaling solution, zk-Rollup. It moves computational work off-chain and only uploads the essential data and proofs to the main chain. This improves transaction speed, reduces fees, and enhances privacy. In simple terms, zkEVM makes Ethereum more efficient and private, while remaining fully compatible with existing smart contracts.
Scroll aims to create a zk-Rollup that is fully compatible with the Ethereum Virtual Machine (EVM). It strives to align closely with Ethereum to ensure full consistency with EVM standards and achieve maximum compatibility. This will allow existing Ethereum applications and tools to migrate seamlessly without the need for code rewrites, providing a more compatible development and user environment.
Currently, the Ethereum ecosystem is dominated by high-risk applications like DeFi and NFT trading, making it difficult for regular users with less capital to get involved. Scroll addresses this by leveraging innovative ZK technology to increase transaction throughput and drastically reduce transaction fees. Its mission is to offer a more accessible and affordable blockchain experience to billions of users worldwide, driving broader blockchain adoption and use.

Ye Zhang holds a bachelor’s degree from Peking University. Since 2018, he has been researching zero-knowledge (ZK) proofs, focusing on hardware acceleration and cryptographic algorithms. During his Ph.D., he continued investigating ZK technology, aiming to solve its inefficiencies. In 2021, Ye met his co-founders and decided to apply ZK technology to enhance Ethereum’s scalability.
Haichen Shen graduated from Tsinghua University’s Yao Class and completed a Ph.D. at the University of Washington, specializing in low-level systems. After graduation, he worked at Amazon on machine learning system architecture, demonstrating outstanding engineering skills and an ability to apply theoretical concepts practically.
Sandy Peng graduated from the University of Cambridge and previously conducted research at the Hong Kong Securities and Futures Commission. She started investing in Web3 projects in 2017 and has been involved in gaming and product operations. Sandy now manages the team’s non-technical aspects, with expertise in branding and strategic planning for startups.
The team is globally distributed, with members based in China, the United States, Singapore, and Europe, reflecting the project’s decentralized nature.
In April 2022, Scroll completed a $30 million Series A funding round, led by Polychain Capital, with participation from Bain Capital Crypto, Robot Ventures, Geometry DAO, Ethereum Foundation’s Ying Tong, Carlos Aria, and Ethereum community members such as Anthony Sassal, Ryan Adams, and Santiago Santos.
In March 2023, Scroll raised an additional $50 million, with investors including Polychain Capital, Sequoia China, Bain Capital Crypto, Moore Capital Management, OKX Ventures, Variant Fund, Newman Capital, IOSG Ventures, and Qiming Venture Partners. The funds will be used to advance product development, launch the mainnet, and expand the ecosystem. Scroll plans to expand its team from 60 to nearly 100 people.

1.One of the standout features of Scroll is its bytecode-level zkEVM compatibility. This allows existing Solidity, Vyper, and Huff smart contracts to run on Scroll without major modifications or re-audits, giving developers an Ethereum-like experience both in terms of user and development processes.
Unlike other ZK-Rollup solutions like zkSync and Starkware, Scroll offers “native” EVM compatibility, rather than just language compatibility. Platforms like Starkware use the Cairo language, and while zkSync supports Solidity, their underlying virtual machines are still different. These platforms need special compilers to convert contracts into formats suitable for zk technologies, but Scroll provides true EVM compatibility, ensuring better compatibility and flexibility for developers.
