Solana Blockchain School

This project implements a decentralized school management system on the Solana blockchain using Program Derived Addresses (PDAs). It allows for student enrollment, class registration, and book distribution, all managed through blockchain technology and NFTs.

Features

• School account management with administrator controls
• Student enrollment with unique NFT-based student IDs
• Class registration system using PDAs
• Digital book distribution through NFTs and PDAs
• Enrollment fee management

Key Components

School Account

• authority: Public key of the school administrator
• baseEnrollmentFee: Cost to enroll in the school (in SOL or lamports)
• classCount: Number of registered classes
• bookCount: Number of registered books
• studentCount: Number of Students registered
• name: School name
• shoolType: HighSchool, College or University,
• FeeMultiplier: Calculate the overall school fee based on the schoolType and baseEnrollmentFee.
• bump For easy identification of the school PDA account.

Course Account (PDA)

• name: Name of the Course
• nftMetadata: Address of the class NFT metadata
• capacity: Maximum number of students
• enrolledStudentsCount: Current number of enrolled students
• tuitionFee: Cost to attend a course
• school: School providing this course

Book Account (PDA)

• name: Name of the book
• nftMetadata: Address of the book NFT metadata
• totalSupply: Total number of copies
• availableCopies: Number of available copies

Student Account

• studentId: Unique identifier for the student
• studentNft: Address of the student's ID NFT
• enrolledClasses: List of class PDAs the student is enrolled in
• ownedBooks: List of book PDAs the student owns
