EVM Basics
What is EVM?
The Ethereum Virtual Machine (EVM) is a runtime environment for smart contracts in Ethereum. Verychain maintains full compatibility with EVM, allowing developers to deploy and run Ethereum smart contracts seamlessly.
Key Concepts
1. Smart Contracts
Self-executing contracts with the terms directly written into code
Written in Solidity or other EVM-compatible languages
Deployed on the blockchain and immutable once deployed
2. Gas
Unit of computational effort
Required for all operations on the network
Prevents infinite loops and spam
3. Accounts
Externally Owned Accounts (EOA)
Controlled by private keys
Can send transactions
Contract Accounts
Controlled by code
Can execute smart contracts
4. Transactions
Data packages that trigger state changes
Include:
From address
To address
Value
Data
Gas limit
Gas price
