Imagine a computer that exists in the cloud, accessible to anyone in the world, that can execute complex contracts without any interference from third parties. Doesn’t it sound like a concept from a science fiction film? 

But the Ethereum Virtual Machine (EVM) makes this futuristic technology a reality. The EVM is the behind-the-scenes powerhouse that executes smart contracts on the Ethereum blockchain, enabling developers to create decentralized applications (dApps) that can revolutionize industries from finance to supply chain management. 

In this beginner’s guide, we’ll explore the world of EVM and how it’s changing the game in the world of cryptocurrency

What is an EVM?

The Ethereum Virtual Machine (EVM) is a vital component of the Ethereum blockchain, responsible for executing smart contracts in a decentralized manner. It is essentially a virtual computer that runs on the Ethereum network, executing code developers have created to automate various functions, from financial transactions to supply chain management. 

The EVM is responsible for processing and executing these smart contracts across the network, allowing developers to create decentralized applications (dApps) that can function without any central authority or interference. Its decentralized nature makes it an ideal tool for various use cases, from simple financial transactions to complex enterprise applications.

Functions of EVM

In layman terms, EVM is an extensive database that holds all the accounts and balances of Ethereum. At the same time, it works as a machine that executes machine codes and changes with every block, which is a new addition to the blockchain ledger

Some of the most common functions performed by EVM are:

Smart Contracts:

One of the primary functions of the EVM is the execution of smart contracts. Smart contracts are contracts that are coded and stored on the Ethereum blockchain, capable of self-executing their terms without the need for intermediaries. The EVM is responsible for executing the code of these contracts, ensuring that they run exactly as intended without any possibility of tampering or interference from third parties.

Gas Usage:

Another key function of the EVM is calculating and managing gas usage. Gas is a unit used to measure the computational effort required to execute a given smart contract. The EVM is responsible for calculating the amount of gas required to execute a contract, and users must pay a fee in ether (ETH) to cover the cost of gas. This ensures that the Ethereum network operates fairly and efficiently, with users paying only for the computational resources they use.

Decentralized Consensus:

The EVM also plays a crucial role in maintaining the decentralized consensus, a hallmark of the Ethereum blockchain. It does this by ensuring that all nodes on the network execute smart contracts in the same way, using the same rules and calculations. This consensus mechanism helps ensure the integrity and security of the Ethereum network, making it an ideal platform for developing decentralized applications. 

Working of an EVM 

The Ethereum Virtual Machine (EVM) is like the brain of the Ethereum blockchain. It executes the code that powers smart contracts and decentralized applications. The EVM is a virtual machine that runs on every node on the Ethereum network. 

When a smart contract is created on the Ethereum network, it’s written in Solidity programming language. The code is then compiled into bytecode, deployed to the network, and stored on the blockchain for the EVM to execute.

To execute a smart contract, the EVM first calculates the gas required to perform the necessary computations. Gas is a unit used to measure the computational effort required to execute a smart contract, and users must pay a fee in ether (ETH) to cover the cost of gas

Once the gas cost has been calculated, the EVM begins executing the bytecode of the smart contract one instruction at a time. As the code runs, it can interact with other contracts and the state of the Ethereum network. The EVM’s secure and isolated environment is essential for ensuring the integrity of the network. 

EVM-Compatible Blockchains

The Ethereum Virtual Machine (EVM) is a powerful tool that enables the execution of smart contracts on the Ethereum blockchain. But did you know that EVM is also compatible with other blockchain platforms? That’s right – a growing number of blockchains have implemented EVM compatibility, allowing developers to create decentralized applications using Solidity, the programming language of Ethereum.

One of the most popular EVM-compatible blockchains is Binance Smart Chain (BSC), built on the Binance exchange. BSC is designed to be fast and affordable, with low transaction fees and high output. 

Another blockchain that supports EVM is Polygon, formerly known as Matic Network. Polygon is a Layer 2 scaling solution for Ethereum, which aims to provide faster and cheaper transactions for users.

Other notable EVM-compatible blockchains include Huobi ECO Chain (HECO), OKExChain, and Avalanche. Each platform has unique features and benefits, making them appealing options for developers and users alike.

By exploring the various blockchains that support EVM compatibility, we can see the immense potential of this technology to enable the creation of decentralized applications across multiple platforms. As the blockchain ecosystem evolves, seeing how the EVM will play a key role in shaping its future is exciting.

Ethereum Ecosystem Interoperability

Ethereum Ecosystem Interoperability refers to the ability of different components within the Ethereum blockchain ecosystem to interact with each other and external systems and networks seamlessly. This includes the Ethereum Virtual Machine (EVM) and various tools, protocols, and standards that support interoperability and collaboration.

Interoperability is a key goal for the Ethereum ecosystem, as it enables developers and users to leverage the full potential of decentralized applications and smart contracts. 

One of the key protocols that support interoperability within the Ethereum ecosystem is the ERC-20 standard, which defines a common set of rules for creating and implementing tokens on the Ethereum blockchain. Many projects have widely adopted this standard, enabling the seamless transfer of tokens between different platforms and networks.

In addition to ERC-20, several other protocols and tools support interoperability within the Ethereum ecosystem, such as the ERC-721 standard for non-fungible tokens (NFTs) and the Cross-Chain Interoperability Protocol (CCIP) for cross-chain communication.

Limitations of EVM

If you’re exploring the Ethereum ecosystem, it’s crucial to understand the ins and outs of the Ethereum Virtual Machine (EVM). While the EVM is a powerful tool for executing smart contracts, it also has a few limitations to remember. After all, no technology is perfect! Here’s what you need to know:

  • The gas mechanism causes high transaction costs
  • Scalability can be an issue as the demand for computational resources increases
  • Solidity programming languages can be complex and difficult to learn for some developers. 

Future of EVM

Ethereum blockchains and EVMs are only at the beginning stage. In the coming years, the system’s complexity, speed, and ability will only increase. It would go up the same way PCs of the old times evolved into the processing units we use today. 

With the Ethereum protocol successfully finishing the Merge of the Mainnet and Beacon Chain, the next goal is to shift from EVM to Ethereum WebAssembly (eWASM). This could prove to be a game-changer for the Ethereum protocol as it is specially designed to improve processing speed. 

EVMs are not considered perfect since the transaction speed is slow and ruining the system. Currently, they want to focus on the growth of Ethereum development to bring on the level of success and increased usage. It can be better only if improvements are made to give promising results.
