Understand the virtual machine of Ethereum (EVM): a deep immersion in cryptocurrency
The increase in cryptocurrencies has revolutionized the way we think about digital assets and decentralized applications. Among these cryptocurrencies is Ethereum, one of the most popular platforms to build intelligent contracts and decentralized applications. In the heart of Ethereum is its virtual machine, the Ethereum virtual machine (EVM), which allows the execution of complex transactions and programs in the block chain.
What is the EVM?
Ethereum Virtual Machine is a software -based platform that allows developers to create, implement and interact with intelligent contracts in the Ethereum Network. It is essentially a virtual computer that executes written code in a variety of languages, including solidity (the programming language used for Ethereum's smart contracts), JavaScript and others.
How does the EVM work?
The EVM is based on the web3 specification, which provides a framework to build decentralized applications in blockchain networks. Here is a general high level description of how it works:
Execution of the transaction : When a transaction is sent from one address to another, it is verified by nodes in the network and is verified with the local copy of the block chain.
Code implementation : The EVM compiles the smart contract code implemented in a format that can be executed directly by the node that executes the Ethereum virtual machine (EVM).
Execution : The EVM executes the intelligent contract implemented, which implies calculating, verifying the integrity of the data and enforcing the rules defined within the contract.
Storage and update : Once an execution is completed, the EVM updates the state of the block chain with the new data.
Key features of the EVM
The Ethereum virtual machine has several key features that make it a powerful platform to build decentralized applications:
Gas -based prices : The cost of executing network transactions is based on gas (Gigahash) used to compile and implement intelligent contracts.
STATE STORAGE : The EVM allows developers to store state data locally, which can be accessed by nodes that execute the Ethereum virtual machine.
Introperability : The EVM allows a perfect interaction between different networks and blockchain applications.
BENEFITS OF EVM
The Ethereum virtual machine offers several benefits for developers, users and the broader ecosystem:
Decentralized applications (DAPPS) : The EVM allows the creation of complex and decentralized applications that can interact with each other without centralized authority.
Intelligent contracts : The EVM allows the execution of automated rules and decisions, which can be used to create self -sufficient systems.
Open source software
: The EVM is open source, allowing developers to contribute to their development and improve it over time.
Challenges and limitations
Although the Ethereum virtual machine has made significant contributions to the development of decentralized cryptocurrencies and applications, there are several challenges and limitations that must be addressed:
Scalability : The current state of the EVM is limited by its scalability, which can hinder large -scale implementation.
Security : Ensure the safety of intelligent contracts in the Ethereum network requires a careful implementation and evidence.
Introperability : The integration of the EVM with other networks and blockchain applications raises significant technical challenges.
Conclusion
Ethereum Virtual Machine is a powerful platform that has revolutionized the way we build decentralized applications and cryptocurrencies. Its key characteristics, including gas -based prices, state storage and interoperability, make it an ideal option for developers seeking to create complex contracts and DAPP.
