The crypto world has now become popular worldwide. There is hardly anyone at present who doesn’t know about the “crypto business industry.” And due to the rise of Bitcoin and its blooming, different cryptocurrencies are taking over the crypto market.
Along with the introduction of Bitcoin in 2009, the world’s perspective regarding the cryptocurrency market changed drastically when it interacted with the decentralized blockchain protocol system.
The blockchain system brought a storm in the crypto world and gained worldwide recognition and acceptance due to its unique features and advantages. And with that, all the major crypto exchange platforms took a revolutionary step and moved towards utilizing the blockchain networks as a safe and robust crypto platform. The Ethereum platform is the one top-listed among them.
With the support of blockchain technology, Ethereum stepped forward, embracing new innovative features and options in its platform, and the introduction of the Ethereum virtual machine is one of them. So, what is Ethereum virtual machine in blockchain?
Ethereum has its own native “scripting language” (known as Solidity), and it is “Turing-complete,” but there is no program to run this code. So there came the requirement to create a program that can run this code, and the development of an Ethereum virtual machine or EVM fulfilled this requirement.
This EVM program works with the support of the Ethereum network and for executing “smart contracts,” offering a “runtime environment.” Every time there is a smart contract execution, all the nodes run over the entire Ethereum network and “reach a consensus” about which code will be applied.
History Of Ethereum Virtual Machine (EVM)
As per the data fetched from Ethereum virtual machine GitHub, it was Vitalik Buterin (a programmer) who first thought about the concept of the Ethereum virtual machine, And then later, when the Ethereum network was on an entire run, Gavin Wood at Ethereum gave a realistic touch of that concept and designed the entire EVM system that the decentralized application developers now use on the Ethereum blockchain network.
The EVM is programmed in C++ languages and is supported by the “LLVM project compiler,” which empowers it to decide the functionality of each node as well as define block state-changing rules of blocks.
What Is The Purpose Of Ethereum Virtual Machine (EVM)?
EVM crypto runs over the Ethereum blockchain network and is a “turing complete” machine. It enhances its ability to be used in any programming language, making it easy for developers to create the dApps in any machine language and test and use it on the EVM.
The purposes of the EVM are as follows –
- It works as a storage space and stores ledger, records, and data on the blockchain network just like any other crypto platform, but what makes it different is that it can also run codes for “smart contract” execution running over the Ethereum blockchain network.
- It helps to boost the speed of transactions by automatically executing commands and procedures of “smart contracts” based on predetermined code matching. Further, if a command does not match the pre-settled codes, then the Ethereum virtual machine system can also go ahead with an “exit” function.
- The machine is built with compiled Solidity (EVM programming language) in it and thus is capable of running every type of “smart contract” that supports the Ethereum blockchain network.
How Does Ethereum Virtual Machine (EVM) Work?
The EVM Work depends on its two crucial parts, which are –
- The central EVM part supports various programming languages, customizing the feature of writing EVM byte code, runtime environment, etc., through its Solidity coding system.
- Small parts or pieces of data or smart contracts called “uncles” allow users or developers to store their programming data (even huge ones).
With the help of these two crucial parts, the EVM blockchain list running over the Ethereum network works on creating tokens. With every input from the user, EVM creates an output following a predetermined algorithm for executing the function. It works like a stack machine and contains around 1024 items, each of which is a 256-bit word.
When a transaction happens through a smart contract, the EVM checks the nodes and decides on the perfect codes by changing Ethereum’s state so that the command can meet with its matching functions for executing the transaction.
What Are The Benefits Of Ethereum Virtual Machine (EVM)?
The EVM benefits include the following –
- No data risk
The EVM is a separate programming system and operates without being indulged in the central system or involved with other areas of the system. Hence, users can have safe data storage and run any function without the fear of data loss on the Ethereum network.
- Easy writing
The introduction of EVM made it easy for developers to create dApps and write functions for smart contracts in their preferred programming language, as the EVM can understand all machine languages. It also ensures that all the distributed ledgers have the exact version of the dApps so that every user can have the same version.
- Efficient running facility
The EVM feature allows users to operate “complex smart contracts” without considering the reaction. By creating a single contract, developers can access crypto deals on multiple platforms through the Ethereum Virtual Machine feature.
Apart from the ones mentioned above, there are several other benefits of EVM, such as – its deterministic way of processing, the capability of distributed consensus, less fear of failure when updating multiple nodes, etc.
Does Solana Use Ethereum Virtual Machine?
EVM Use Cases shows that the popular blockchain Solana project was initially designed to improve the Ethereum system. So, considering the point, Solana uses and supports EVM compatibility and allows developers to access the network for their “Ethereum-based dApps” without the requirement of changing the codebase.
What Are The Disadvantages Of Ethereum Virtual Machine (EVM)?
Although EVM Ethereum makes it easier for developers to create and write dApps and smart contracts on the blockchain network, it also has some disadvantages. Those are as follows–
1. Cost of storage
The Ethereum network applies a specific fee for providing all the facilities and features to the dApps developers and smart contract scriptwriters and storing data on the EVM system. And the charge is not always a minimum but a hefty one, as much as around 3TB.
2. Cost of gas
The payment mode on the Ethereum network is addressed as “gas,” and thus, one has to pay the gas through the ETH tokens every time one performs any transactional execution.
However, one can only check the gas price when the transaction is about to be executed and how much the gas charge will be, which depends entirely on the complexity level of performing the transactional execution. The gas price tends to increase with the complexity level of the transactional execution.
Similarly, whenever there is network obstruction on the blockchain system, the gas prices become higher as only a few transactions get executed at that moment.
3. Technical misuse
The EVM is based on the “turning complete system,” which can support any programming language, allowing the developers to create and write commands in their preferred language. This makes the platform available to all for using and testing dApps, so anyone with wrong intentions can easily use it to meet their requirements.
What Is The Future Of Ethereum Virtual Machine (EVM)?
After walking on the path of the EVM blockchain, several other blockchain projects have also come up with their own “EVM compatible blockchain system.” They offer better service at an affordable gas price than the Ethereum network.
However, this does not affect EVM’s promising future after the “Ethereum protocol” completed its Merge successfully in September 2022.
And now, Ethereum has set its eye on the next big project by taking a revolutionary move to change the EVM to “Ethereum WebAssembly,” or the “eWASM,” for executing smart contracts on the Ethereum blockchain with its highly modular and platform-independent features.
And it is expected by many that “eWASM” will take the crypto world to a new level in terms of crypto transactional experience.
