what is Ethereum Virtual Machine

EVM is a simple stack-based execution machine that runs bytecode instructions to transform the state from one state to another on the Ethereum blockchain. The word size of the virtual machine is set to 256-bit. The stack size is limited to 1024 elements and is based on the LIFO (Last in First Out) queue. EVM is a Turing-complete machine but is limited by the amount of gas that is required to run any instruction. This means that infinite loops that can result in denial of service due to malicious attacks or inadvertently are not possible due to gas requirements. EVM also supports exception handling in case exceptions occur, such as not having enough gas or invalid instructions, in which case the machine would immediately halt and return the error to the executing agent. EVM is a stack-based architecture. EVM is big-endian by design, and it uses 256-bit wide words. This word size allows for Keccak 256-bit hash and elliptic curve cryptography computations. EVM is a fully isolated and sandboxed runtime environment. The code that runs on the EVM does not have access to any external resources, such as a network or filesystem.
