EVM Equivalence Explained

What is EVM Equivalence?

EVM Equivalence is a critical component of Ethereum's Layer 2 scaling solutions. It ensures that these solutions align perfectly with the standards of the Ethereum Virtual Machine (EVM). This consistency enables applications designed for Ethereum's mainnet to work effortlessly on Layer 2 rollups, enhancing the network's cohesion. EVM Equivalence brings Ethereum's community, tools, and protocols to Layer 2, effectively broadening Ethereum's influential network effects.

Moreover, EVM Equivalence significantly boosts Ethereum's scalability by minimizing differences between the primary network and Layer 2 networks. It provides a reliable framework for innovation, allowing rollups to act as direct expansions of the mainnet. This cohesive approach simplifies development processes and creates an effective environment for testing and applying Ethereum Improvement Proposals (EIPs), which are essential for the ongoing evolution and enhancement of the platform.

How does EVM Equivalence Work?

EVM Equivalence is essential to Ethereum's scalability strategy by ensuring strict compliance with the Ethereum Virtual Machine (EVM) specifications. Let's examine how it functions:

• ‍Strict Adherence to EVM Specifications: EVM Equivalence requires complete alignment with the EVM, which allows for the seamless operation of applications from Ethereum's mainnet on any EVM-equivalent Layer 2 network.‍
• Replication Across Layers: Developers can directly transfer DeFi applications and smart contracts from the mainnet to EVM-equivalent rollups. This simplifies the development process by eliminating the need for extensive code modifications.‍
• Testing Ground for Ethereum Improvement Proposals (EIPs): EVM-equivalent Layer 2 networks serve as ideal platforms for experimenting with EIPs. They allow for testing in diverse economic conditions without impacting the mainnet, leading to safer and more efficient updates.‍
• Utilization of Established Network Effects: By maintaining EVM Equivalence, Layer 2 solutions leverage Ethereum's existing network effects, gaining access to its comprehensive tools, smart contracts, and extensive user base.‍
• Enhanced Interoperability and Composability: EVM Equivalence ensures high interoperability within the Ethereum ecosystem. It allows applications across different EVM-equivalent networks to interact smoothly, creating a more cohesive blockchain environment.‍
• Fostering Innovation and Adoption: EVM Equivalence facilitates the swift deployment and adaptation of new applications and protocols, accelerating technological progress and encouraging wider adoption within the Ethereum landscape.

EVM Equivalence is crucial for enhancing Ethereum's scalability and fostering its continual evolution, effectively merging Ethereum's foundational strengths with innovative scalability solutions.

EVM Equivalence vs EVM Compatibility

EVM Equivalence and EVM Compatibility are vital in integrating L2s with Ethereum, but they differ in alignment and functionality with the Ethereum Virtual Machine (EVM):

• EVM Equivalence: EVM Equivalence ensures full alignment with the Ethereum Virtual Machine's specifications. This means any application or protocol on Ethereum's mainnet can operate seamlessly on EVM-equivalent Layer 2 networks, without needing modifications. It's ideal for scenarios requiring directly replicating Ethereum's mainnet functionalities on Layer 2 platforms.
• EVM Compatibility: EVM Compatibility, while allowing Ethereum-based applications to function, does not ensure a complete adherence to EVM standards. It supports most, but not all, Ethereum functionalities, potentially necessitating some adjustments in applications. This approach benefits applications that can accommodate slight variations to leverage specific features of Layer 2 networks.

In essence, EVM Equivalence ensures identical functionality to the Ethereum mainnet, while EVM Compatibility offers flexibility with some deviation from the EVM standards.

EVM Equivalent Chains

Here are notable EVM equivalent Layer 2 networks:

• ‍Optimism: This Layer 2 solution employs Optimistic Rollups to preserve full EVM Equivalence, allowing it to process Ethereum smart contracts and transactions efficiently. It offers users reduced fees and faster transaction confirmations compared to Ethereum's mainnet.‍
• Polygon zkEVM: As a key component of Polygon's broader strategy, this network uses zero-knowledge proofs to maintain scalability while adhering to EVM standards. It supports the direct transfer of DApps and smart contracts from Ethereum, enhancing developer and user experience.‍
• METIS: This platform maintains compatibility with the EVM and focuses on creating a user-friendly, scalable, and cost-efficient Layer 2 network. Its primary aim is to augment Ethereum's utility in decentralized finance (DeFi) and Web3 applications.‍
• Hedera: Although originally not based on EVM, Hedera is moving towards EVM Equivalence to tap into the robust Ethereum ecosystem. It integrates this feature with its distinct hashgraph consensus, which significantly increases processing speed and efficiency.‍
• Linea: Linea operates as an EVM-equivalent rollup, faithfully replicating the EVM’s structure and functionality. This ensures seamless integration with the Ethereum mainnet, providing a familiar environment for developers.‍
• Flow: Designed specifically for gaming applications, Flow is an EVM equivalent chain that extends the security features of Ethereum whilst significantly increasing throughput. This capability is bolstered by its innovative Crescendo upgrade.

Each of these platforms adopts a unique method to achieve EVM Equivalence, addressing various needs within the blockchain space and ensuring a robust link with Ethereum's ecosystem.
