The Ethereum Blockchain is currently the second-largest project in the world of cryptocurrencies, this is due to the revolutionary technology that has managed to stand out from other similar projects, that technology refers to the Ethereum Virtual Machine (EVM), which is a virtual machine on which the entire Ethereum operating structure depends.

What is a virtual machine?

A virtual machine or Virtual Machine (MV) is software whose design allows us to create an emulation layer of what a real computer is, in other words, a virtual machine is a computer whose creation and operation depend on the software. This machine does all the functions of a computer, that is, it has the ability to “recreate” a RAM memory processor, hard drives, network cards, and any hardware device that is required.

A VM can run specific software (within that virtual machine), it is like having a “complete computer” within another computer. Virtual machines allow the creation of highly flexible software, which allows you to offer unique functions, for example, you can create a virtual machine that acts on a series of unique instructions (with well-defined behaviors and isolated from the systems that execute them), all this economically and with great development potential.

Principal function

The main function of a virtual machine is to allow the execution of Ethereum’s own programs such as Smart Contracts, to deploy a series of added functionalities on the Blockchain so that users can make use of them and operate without problems within the Blockchain.

How does EVM work?

To prevent a programmer from threatening the security of the network, the machine performs a complete abstraction of the system. It does this by managing access to computer resources and limiting actions in a controlled environment or virtual machine. Likewise, the Ethereum virtual machine simplifies the development, update of applications, and features available for decentralized applications.

The Ethereum Virtual Machine (EVM) enables smart contracts to be designed and executed. For example, thanks to Solidity, creating these contracts is simple and manageable, Solidity is a programming language with a certain resemblance to JavaScript and C ++. Most of the source code for smart contracts is written in this language and is subsequently compiled into opcodes that are understandable to the EVM.

This machine uses these operation codes (OP_CODES) to carry out specific tasks. These types of limitations make the EVM create working methods that allow it to carry out its operations, the most important being the memory of smart contracts. All this makes the EVM work like a real computer, executing from the simplest of operations to the most complex.

The creators of the EVM

The Ethereum Virtual Machine (EVM) is great development work, for this, it required a team of professionals and specialists, among which are Gavin Woods and Greg Colvin. The first was the creator of the well-known Ethereum Yellow Paper, in this technical document the idea and initial capacity of EVM are specified, on the other hand, Greg Colvin became known as the main developer of the EVM. The Ethereum Virtual Machine is a technology that came to transform Ethereum into a unique ecosystem within the other technologies that make use of the Blockchain.

Due to the decentralized feature of Ethereum, its ability to store contacts in the nodes of the network, and that EVMs can execute the orders programmed in said contracts, Ethereum becomes a large decentralized world computer, which has the ability to solve problems, complex computational, which occurs within the same Ethereum network.
