Designed and developed a secure blockchain based distributed online Course Management System, assigned privileges to users and implemented authorizations accordingly
You are a school administrator and you want to put the course registration and grades management on the blockchain.
There are three main parties (create different addresses for them) –
The School Administrator – your main account that will be used for deploying contracts on the chain. It also has the privilege to kill the deployed contracts (you should always have this option as a privileged option if you find a bug in the contract later). Also, only the school admin can add new courses.
Instructor(s) – Each Course has an associated instructor. It has privileges to upload the midsem, endsem marks and also mark the attendance of the student.
Students(s) – Anyone on the network can become a student. They can register for any course that is being offered and can view their marks.
For this you I created two contracts according to the given specifications –
-
Manager Contract – main contract created by the school administrator. Used for adding courses. Also serves as endpoint for students to register for courses, view their grades, etc.
-
Course Contract – every course has an associated course contract. A contract is deployed for every course on the blockchain by the Manager Contract.
