The Ethereum Virtual Machine (EVM) allows for smart contracts created for the Ethereum (ETH) network to be read and executed. Each of the nodes on the Ethereum network uses the EVM in order to execute contracts. Ethereum was created as a decentralized ecosystem for developers in order to deploy and run different smart contracts and applications.
The main question that many enthusiasts ask is what powers the EVM and how it works on the Ethereum blockchain. In this article, we answer this important question and we make an overview of how the EVM works as a whole.
What Powers The Ethereum Virtual Machine?
Before starting, it is very important to understand that the Ethereum Virtual Machine is one of the key elements of the Ethereum network. The EVM is responsible for handling the whole computation of the network.
The Ethereum Virtual Machine works with its own programming language called Bytecode. This is different from other programming languages used in the market, and it is also different from Solidity.
Solidity the main programming language that gives Ethereum strength
Solidity is the programming language used by developers to create smart contracts on top of the Ethereum network. There are other programming languages used for other cryptocurrencies, but Ethereum works with Solidity.
The Ethereum Virtual Machine will basically be compiling that code created by developers using Solidity and transformed into bytecode. In this way, the nodes would have the possibility to understand what was written and what it means.
This would ultimately allow for the whole network to understand what was written in the code and process the request executed by the smart contracts as long as the instructions are clear and correctly written.
Thus the EVM is powered by the bytecode programming language allowing it to process the different lines of code entered by developers. Without it, it would not be possible to decode what developers are writing when deploying smart contracts.
EVM uses GAS token to handle fees
At the same time, one of the most important features of the EVM is related to the Gas needed by developers to power the whole Ethereum network.
The Ethereum network includes a fee scheme that is measured through Gas. Each of the transactions processed by a party in the network would include a small fee that is paid in ETH. This would allow the smart contract or transaction to be powered on the network.
The price paid by users depends on the price of Ether at the time of executing the specific order.
At the same time, Gas helps the Ethereum network avoid spamming attacks, considering that users have to pay for the fees required to execute orders.
In this way, the EVM will be processing all the computational requirements on the network. At the same time, the EVM will be processing different information such as accounts, addresses, balances, Gas and more.
EVM Turing Completeness
It is also worth pointing out that the EVM is Turing complete. That means that the EVM is capable of performing logical steps related to computational functions. Nowadays, almost every single programming language is Turing complete.
As mentioned before, the EVM is essential for the whole Ethereum network to operate considering nodes have an EVM that runs code and executes the orders.
Without being achieving Turing Completeness, the EVM would not have the possibility to work as it should. Nowadays, this feature that powers the EVM allows it to execute software instructions rather than financial transactions such as the ones processed by Bitcoin (BTC).
EVM the key element of Ethereum ecosystem
The Ethereum Virtual Machine is then a key part of the Ethereum ecosystem. Also, it allows developers to create decentralized economies, Initial Coin Offerings (ICOs) and many other projects.
Ethereum expanded in the market during the last few years and became the second-largest crypto and blockchain network after Bitcoin.
This is certainly important because Bitcoin can primarily and almost exclusively perform financial transactions. Ethereum, through the EVM and its capabilities, it is able to go even further and allow developers to execute smart contracts.
Although this is something that could have been done through a traditional centralized system, the advantages of having a decentralized network such as Ethereum are huge.

This article aimed at understanding which was the main characteristic of the EVM and what powered it.
Basically, the EVM transforms code into Bytecode that allows smart contracts to be executed. Without this feature, it would not be possible for nodes to execute smart contracts and code written by developers.
At the same time, Gas will help the Ethereum Virtual Machine process the software instructions embedded into each smart contract running on Ethereum.
Finally, being Turing complete means that the EVM would be able to process logical computational functions. Without it, Ethereum would not be able to perform many of the current tasks it is able to perform.
