There is a fact that confuses the newcomers and even the seasoned investors of the crypto world. It is that Bitcoin, Ethereum, and for the same reason, all other blockchain networks are computers.
Bitcoin is, as a matter of fact, the largest computer on the planet, only that it is distributed among a large number of nodes (users).
Coming back to our protagonist, the Ethereum Virtual Machine (EVM) is a decentralized, Turing-complete virtual machine that operates as the central component of the Ethereum network.
It serves as the runtime environment for smart contracts on Ethereum’s blockchain. Notably, the VM is sandboxed and isolated from the other parts of the system.
This would mean that any operation on the EVM should not have any impact on your data or programs, no matter how frequently you call a particular function on it.
What is EVM?
On the official documentation of the Ethereum project, the contributors note that the existence of EVM cannot be pointed out as a single physical object but it is still a single entity maintained by thousands of computers running the Ethereum client.
To begin, the Ethereum blockchain has a scripting language called Solidity built into it. The Ethereum Virtual Machine (EVM) is essentially a software that executes this code.
EVM runs on top of the Ethereum network, meaning that all nodes can tell what code should be executed at every given time.
Apart from the node networks, other blockchains try to be compatible with the EVM, thanks to the popularity of Ethereum among the dApp and developer communities.
How is Ethereum different?
Though Ether, the native cryptocurrency of the Ethereum network follows the same rules that govern the transactions of Bitcoin, what makes Ethereum more powerful is the Smart Contracts.
This requires more than a distributed ledger to operate. Ethereum can be thus considered a distributed State Machine. Hence the data structure of Ethereum contains a machine state that can change from block to block.
Purpose of EVM
The Ethereum Virtual Machine is programmable software, just like Windows or macOS. EVM can execute scripts to produce arbitrary outcomes.
It has been made like that to be a global computer and has some unbelievable power under its modest hood.
EVM is the computer that stores data on the Ethereum blockchain, like Bitcoin. But it can also execute the code in smart contracts on the Ethereum network.
EVM- Genesis
EVM is made to be compatible with any kind of crypto contracts that are built on top of Ethereum’s blockchain. The software achieves this by using Solidity, which is compiled into the EVM for execution.
The intention behind writing code on the Ethereum network is to create smart contracts and programs that automatically execute things when certain conditions are met, something traditional institutions can do with the help of a centralized authority. If no condition is met, the system can execute it in an “exit” function, closing the smart contract.
How EVM Works?
As already mentioned, Ethereum Virtual Machine is a software that executes some pre-programmed scripts. The script will contain a set of instructions or an algorithm that tells the machine what it needs to do to achieve the necessary results. These are used to implement certain operations usually in a blockchain, mostly Ethereum itself.
EVM also facilitates the process of creating new tokens on the Ethereum blockchain.
The EVM mandates that to execute the desired commands on the blockchain and create new tokens, one should have access to a network node.
Ethereum is home to smart contracts, the software that contains a piece of code that facilitates the exchange of money and information. These contracts will be predefined by the author of the smart contract which will ensure that the desired outcome will happen based on how the conditions in the code play out.
EVM Benefits
Conclusion
In a nutshell, the Ethereum Virtual Machine (EVM) is a powerful tool in the blockchain space. It provides a secure and efficient environment for the execution of smart contracts, making it a vital component of the Ethereum network.
Its ability to execute scripts and create new tokens on the Ethereum blockchain has made it a crucial part of the cryptocurrency ecosystem. As blockchain technology continues to evolve, the role of the EVM is also becoming more significant.
