x86 Virtual Machine

x86 is Qtum’s Virtual Machine (VM), which was generated in Intel’s x86 machine language. The x86 Virtual Machine enables developers to write smart contracts in different programming languages including C, C++, Rust, and Python. Qtum before used the Ethereum Virtual Machine (EVM), but formulated the x86 to extend  on its capabilities. The x86 VM is fully compatible with Solidity (the language built for, and used on the Ethereum network), allowing Ethereum developers to seamlessly build applications on the Qtum blockchain.
