Might I inquire about the fundamental distinctions between ETH and ERC-20? ETH, as we all know, stands for Ethereum, a groundbreaking open-source blockchain platform. It serves as the backbone for decentralized applications and smart contracts, and ETH, its native currency, powers the transactions within this ecosystem. ERC-20, on the other hand, is a technical standard, not a currency itself. It's a set of rules and guidelines that define how tokens should function within the Ethereum network. ERC-20 tokens are built on smart contracts and can be used for a wide range of purposes, from representing assets to serving as utility tokens. So, in essence, ETH is the currency that fuels the Ethereum network, while ERC-20 is a standard that governs the behavior of tokens within that network. Does this clarification suffice, or do you require further elaboration?
