EVM Compatibility Explained

EVM compatibility refers to a blockchain platform's ability to execute smart contracts developed for the Ethereum Virtual Machine (EVM) 1. The EVM is the runtime environment for smart contracts on Ethereum, and compatibility means that a blockchain can support the same execution logic and programming languages, primarily Solidity 1.

Key Aspects of EVM Compatibility

When a blockchain or sidechain is EVM-compatible, it offers several advantages, particularly for developers and decentralized applications (dApps) 1:

Smart Contract Support: EVM-compatible chains can execute smart contracts written in Solidity and other EVM smart contract languages 1.
Ease of Migration: If a developer wants to use their dApp on an EVM-compatible sidechain, they can simply deploy their existing smart contract to that chain 1. The process "looks, feels, and acts just like Mainnet" 1.
Scaling Solution: EVM-compatible sidechains are considered a useful scaling solution for Ethereum-native dApps, allowing users to benefit from faster transactions and lower gas fees, especially when the Ethereum Mainnet is congested 1.

EVM vs. Non-EVM Platforms

The blockchain ecosystem is often divided into platforms that adopt Ethereum's infrastructure (EVM-compatible) and those that operate as independent environments (Non-EVM) 2.

EVM-Compatible Platforms

These platforms support the Ethereum Virtual Machine, enabling compatibility with Ethereum-based smart contracts 2. Examples of platforms that have been identified as EVM-compatible include 2 3:

Ethereum 2 3
Binance Smart Chain (BSC) 2 3
Polygon 2 3
Avalanche 2 3
Fantom 2 3
Arbitrum 2 3
Celo 2
Optimism 3
Cronos 3

The dominance of EVM-compatible platforms demonstrates the prevalent adoption of the Ethereum standard in the blockchain ecosystem 4.

Non-EVM Platforms

These platforms do not utilize the Ethereum Virtual Machine and often prioritize unique architectural approaches 2. Examples of platforms identified as Non-EVM include 2 5:

Solana 2 5
Terra 2 5
Klaytn 2
Cardano 5
Polkadot / Cosmos 5

Non-EVM platforms differentiate themselves through unique features, such as Solana's focus on high speed and low fees, or Polkadot/Cosmos's focus on multi-chain capabilities and cross-chain messaging 5.

Architectural Implementation

EVM compatibility can be achieved through dedicated architecture. For instance, the Berachain Polaris EVM Architecture is built on an Embedded Host Chain and includes a Polaris Ethereum component 6. This component is responsible for EVM operations and contains a State Processor (Geth EVM) that handles the execution of Ethereum smart contracts 6.
