QTUM has been using Ethereum's Virtual Machine since its inception, which has several drawbacks. One of them is that the system supports only one programming language. One of the most recent and important developments of QTUM is the x86 Virtual Machine. This virtual machine exclusive to QTUM can be defined as an advanced version of the standard EVM. To summarize, the QTUM X86 VM is a smart contract operating system, built to make decentralized applications easier to deploy and use. In addition, it enables new possibilities in production, application and management for new period smart contracts, provides alternative data storage and supports multiple APIs for easy plug and play. These innovations will make the process even smoother for developers who want to create applications on the platform.
