1) DApps are designed to operate without a central authority, enabling peer-to-peer interactions and eliminating the need for intermediaries. They typically have the following characteristics:

• They are built using open-source code, allowing anyone to review, audit, and contribute to the codebase.
• DApps often leverage decentralized storage systems like IPFS (InterPlanetary File System) to store and distribute data in a peer-to-peer manner.
• Many utilize tokens as a means of value exchange within the ecosystem.

2) The architecture of a DApp can vary, but it generally includes the following components:

• The user interface (UI) layer of the DApp that interacts with the user. It is typically built using web technologies like HTML, CSS, and JavaScript.
• The backend of a DApp consists of the smart contracts deployed on the blockchain. They define the business logic and rules of the application.
• DApps interact with the blockchain through APIs provided by web3 libraries which enable communication with smart contracts, transaction handling, and retrieval of blockchain data.

3) DApps rely on smart contracts to execute various operations and business logic. To become a web3 developer, it is important to understand how to interact with smart contracts through methods such as calling functions, reading data, and handling events emitted by the contracts.

4) Decentralized apps often require users to have a web3-enabled wallet to interact with them securely.
