Question 2

What programming language is most commonly used to write Ethereum smart contracts?

Accepted Answer

Solidity

Question 3

Which best defines a smart contract?

Accepted Answer

A self-executing program on a blockchain that runs when predetermined conditions are met

Answer

A smart contract is a self-executing program stored on a blockchain that automatically enforces and executes agreed-upon terms when predetermined conditions are met.

Question 4

What is the Ethereum Virtual Machine (EVM)?

Accepted Answer

A runtime environment on Ethereum nodes that executes smart contract bytecode

Answer

The EVM is a runtime environment embedded in every Ethereum node that executes smart contract bytecode, ensuring deterministic and consistent execution across the entire network.

Question 5

What does 'gas' represent in the Ethereum network?

Accepted Answer

A unit measuring computational effort required to execute operations

Answer

Gas measures the computational effort required to execute specific operations on Ethereum; users pay gas fees (in Ether) to compensate validators for the computation performed.
