Ethereum is a decentralized network that allows users to do several things. This blockchain focuses on smart contracts; the programs that operate. If you are familiar with this network with its smart contracts, chances are you have come across the Ethereum Virtual Machine (EVM), one of the main pieces of the network. However, what is it? Please keep reading to find out all you need to know about Ethereum Virtual Machine.
What is Ethereum Virtual Machine?
Like all virtual machines, EVM generally creates a level of abstraction between executing codes and machines. However, what exactly does Ethereum virtual machine refer to? This is software that developers use to create a decentralized application on the Ethereum network. Notably, the platform hosts all smart contracts and Ethereum accounts. Therefore, it is the structure in which the Ethereum network operates.
Additionally, this computation engine contains millions of projects that you can execute. Its main function is to provide extra functionalities to the Ethereum blockchain. This is to enhance user experience and reduce the number of issues they can face on the distribution ledger.
Another important thing to note when it comes to EVM is that it is Turing-complete. What does this mean? Some algorithms run the thinking process of the EVM, and its system can undertake logical steps in any computational function. Hypothetically, since it is Turing-complete, its smart contracts should be able to bring a solution to any problems. Also, the software needs a programming language.

What are Smart Contracts?
When you are acquainting yourself with EVM, you cannot fail to come across smart contracts. What are they? These are self-executing agreements between parties. It means no third party is necessary to supervise how they perform. The parties can transact with one another without depending on a legal system. Moreover, smart contracts are written in codes. Therefore, they are codes running in the Ethereum network. Additionally, they can run through several nodes without compromise.
Who is the Creator of Ethereum Virtual Machine?
When you talk of the creators of the EVM, two names come to mind; Gavin Wood and Greg Colvin. Gavin Wood, the creator of the Ethereum Yellow Paper, is the mastermind behind the development of EVM. In his document, there are specifics of the ideas and capabilities of the EVM. However, the main developer is Gavin Woods. Together with a team, these two brought transformations to the Ethereum network; EVM.
Therefore, it is evident how unique and innovative this software is. No wonder the internal workings of the Ethereum platform feature the Ethereum Virtual Machine.

Foundations of the Ethereum Virtual Machine
These are the essential foundations of this software;
- OP_Codes; these are the defined codes of the operations that the Ethereum Virtual machine can execute. They also refer to low-level machine instructions used in Ethereum. The different OP_CODES the EVM can perform are up to 256. However, they are no longer as many because their creation isn’t a requirement of EVM and the number of codes is limited. Importantly, the OP_CODES are EVM’s intermediate level of programming.
- Bytecode; this results from using an equivalent of EVM’s machine language to compile OP_CODES. Therefore, it is EVM’s machine language and it can be decompiled. When it is made more readable, EVM can have openness and clarity in its smart contracts. So, bytecode is the form in which opcodes are encoded for efficient storage.
Gas Fee and EVM Performance
In the Ethereum network, Gas refers to the fees for transactions on the platform. Also, ETH, Ethereum’s cryptocurrency, represents every operation taking place in the network. Therefore, how does Gas relate to EVM in the Ethereum platform?
When you run programs on their network, you will get some form of fee rather than the transaction cost. Therefore, their system costs depend on each software instruction, not each money transaction that occurs.
Additionally, gas fees help determine the kind of function to give priority in the system. When the limits set for a gas fee are over, the processes and operations in the machines end.

How to Get Started
If you want to join the EVM economy and become a participant, you can download the implementation of Ethereum. Once you have it installed, you can run a full node. Besides, you can even initialize EVM in its blank state copy after which you can download the history of the Ethereum which entails the blocks, right from block zero. Remember, to have Ethereum reach its current state you should replay all the blocks’ transactions.
- There are no barriers or restrictions since anyone can create a decentralized application on the network.
- It helps create non-fungible tokens, NFTs.
- It focuses on security provision for all users e.g., those making virtual payments.
- The applications do not no need third-party participation.
- Helps reduce costs since there is automation of smart contracts.
- Helps save time since the smart contracts on the software can undergo self-execution or automation.
- It allows the development and execution of a great number of applications on one blockchain network.
- It is not yet a completely decentralized network. Ethereum hosts most of its nodes on other servers. The drawback of this is that you never know when the service owners will no longer like Ethereum and hence turn down their nodes, leading to network damage.
- The gas expenses are high when there is congestion in the network. This affects the users of the platform, especially the ones sending smaller transactions.
- The network requires coding experts.
- The interface is not very user-friendly; not everyone knows how to code.
- Its efficiency is less than other conventional virtual machines. This is attributed to its design which was not based on high performance.
- There have been few changes and improvements on EVM, hence, a lack of speed optimization for different hardware.
Ethereum Virtual Machine is a provision from Ethereum to allow the developers to build products in the decentralized ecosystem. It is a breakthrough concept in blockchain and allows decentralized networks to perform more than just processing basic transactions. Moreover, it uses resources in running programs. Interestingly, getting started with the system isn’t quite a hassle.
