## Virtual Machines

A virtual machine is the environment within a blockchain where smart contract code is executed. It acts as a sandboxed computer that operates according to the rules of the network.

The most well-known example is the Ethereum Virtual Machine, which allows developers to write complex financial applications that run on the blockchain. The VM is responsible for the deterministic execution of code, ensuring that all nodes process the same instructions.

In derivative protocols, the VM handles the logic for calculating margin, checking liquidation conditions, and updating user positions. It is isolated from the underlying operating system of the node, which provides a layer of security against exploits.

However, this isolation also limits the computational power and memory available to smart contracts. Developers must optimize their code to run efficiently within the constraints of the VM.

It is the core execution layer that turns static blockchain data into programmable money. Without a secure and robust VM, the complexity required for advanced financial derivatives would be impossible to achieve.
