What is flow in Web3?

Could you please elaborate on what "flow" actually means in the context of Web3? I'm interested in understanding its significance and how it fits into the broader landscape of decentralized technologies. Could you provide an explanation in simple terms, breaking down its core principles and potential applications? Also, how does flow differ from other blockchain-based solutions? I'm keen to know the specific advantages it offers and how it's shaping the future of Web3. Thank you for your insights.
