Imagine building a house. You could use special pre-made sections for the walls (appchains) that are strong and easy to customize. But you also need a way to easily connect everything together (smart contracts). An integrated application is like a house built with both of these things. It combines the best features of appchains (customizable, fast, and works well with other systems) and smart contracts (easy to build upon, standardized, and efficient) This makes it easier for developers to build powerful blockchain applications that can attract a wide range of users.
