 While [PolkaVM](/polkadot-protocol/smart-contract-basics/polkavm-design/){target=\_blank} strives for maximum Ethereum compatibility, several fundamental design decisions create necessary divergences from the [EVM](https://ethereum.org/en/developers/docs/evm/){target=\_blank}. These differences represent trade-offs that enhance performance and resource management while maintaining accessibility for Solidity developers.

 ## Core Virtual Machine Architecture
 
 The most significant departure from Ethereum comes from PolkaVM's foundation itself. Rather than implementing the EVM, PolkaVM utilizes a RISC-V instruction set. For most Solidity developers, this architectural change remains transparent thanks to the [Revive compiler's](https://github.com/paritytech/revive){target=\_blank} complete Solidity support, including inline assembler functionality.
