Briefly in this section, I explained how it boils down. Three things come to play here: Ethereum Virtual Machine, Gas, and Solidity. Functions and Smart Contracts When a smart contract gets compiled (translated into machine language so that Ethereum can understand it), it's hashed – compressed into an unreadable format. Because of this, a special bit of code called ABI is required to interact with a smart contract. Every transaction or smart contract executed on the Ethereum blockchain requires gas.
