EXPERIMENTATION WITH NFT MARKETPLACE
System Model
The system model of a marketplace consists of three main parts: the user interface (FrontEnd), the backend processing, and smart contracts:
- User Interface (FrontEnd): The homepage displays popular NFTs, events, and important information Pages like create NFT, mint NFT, put on sale, and buy NFT allow users to perform actions to interact with the website and Metamask
- Web Processing Part (BackEnd): This part runs APIs and handles requests sent to the database to process these requests
- Smart Contracts: Manages requests that need interaction with the blockchain
Each part of the system model plays a crucial role in ensuring flexibility, security, and convenience for users participating in the NFT market
- Frontend and Backend: Communication through API (RESTful) The frontend sends requests, and the backend processes and returns data
- Backend and Smart Contracts: The backend sends requests to smart contracts when there are new transactions Smart Contracts confirm and execute the transaction process
- Frontend and Smart Contracts: The frontend sends requests to the smart contract through the Metamask wallet and then receives results from the smart contract to interact with backend APIs if necessary.
System Configuration and Setup
The project is divided into two parts for easier development: the smart contract part and the application interface part The environmental requirements for each part are as follows:
The development environment for the smart contract part requires:
