EVM Quiz

Understanding the Ethereum Virtual Machine (EVM)

• The EVM is a virtual machine or a cloud computer that is operated by all the nodes contributing to it on the Ethereum network.
• The EVM is not a single computer but an accumulation of thousands of computers around the world.
• Each computer on the Ethereum network runs a piece of software that computes the output of smart contract transactions.
• Smart contract code written by developers is what the EVM processes, and the most common language used is Solidity.
• Solidity is human-readable code that gets compiled into bytecode, which the EVM reads and processes.
• The bytecode is a bunch of ones and zeros, which is a machine-readable language.
• Each smart contract can be broken down into a list of operations named by their op code names, and some op codes are more expensive than others.
• The total cost of a smart contract is determined by the work the EVM performs, whether it's reading or writing data, and how much data it reads or writes.
• Transactions submitted to the EVM are processed sequentially, one by one, and each transaction changes the state or the collection of data that the EVM holds.
• The EVM is easy to move between different chains if they both use the EVM, making it easy to move projects and applications from one chain to another.
• The EVM is a specialized computer designed to process DeFi transactions and is made up of parts similar to a real computer, such as memory storage and a part specialized for computing numbers.
• The EVM doesn't need a monitor, keyboard, or mouse, but it needs a part to understand and read smart contract code and a few unique pieces, such as a part to read bytecode.
