The FVM (Filecoin Virtual Machine) and the EVM (Ethereum Virtual Machine) are both virtual machines designed to execute smart contracts on their respective blockchain networks. However, there are several key differences between the two: Programming languages: The EVM is designed to execute smart contracts written in the Solidity programming language, while the FVM supports multiple programming languages, including Rust and C++. This makes it easier for developers with different backgrounds and skillsets to build applications on the Filecoin network. Consensus mechanism: The EVM is based on proof-of-work (PoW) consensus, while the Filecoin network uses a proof-of-replication (PoRep) and proof-of-spacetime (PoST) consensus mechanism. This means that the FVM has different requirements for contract execution, such as the need for proof-of-replication and PoST verification. Storage: The EVM executes smart contracts on the Ethereum blockchain, which has its own built-in storage capabilities. In contrast, the FVM is designed to interact with the Filecoin network, which provides decentralized storage for smart contract data and state. Gas fees: Both the EVM and FVM require users to pay gas fees to execute smart contracts, but the way these fees are calculated and paid is different. In the EVM, gas fees are paid in Ether, while in the FVM, gas fees are paid in Filecoin. Overall, while both the EVM and FVM are designed to execute smart contracts on their respective blockchain networks, they have different design choices and requirements due to the differences in their consensus mechanisms, programming languages, and storage architectures.

The main difference is that you can build perpetual storage on Filecoin, Unlike on Etherium. it’s introducing the ability for early builders to develop something on Filecoin directly. If you don't realy understand what the perpetual storage is you can check [this post](https://pl-launchpad.peeranha.io/experts/1453/what-is-perpetual-storage%3F)
