The Value Creation-and Trading Project: VCaT Project ---Cognitive science
Owner: that owns the contract and adds/removes valid admins to/from the system
Admin:
1- Given a list of students’ numbers it registers them in the system. The list contains the list of students who enrolled in the course
2- Given a list of students’ addresses (in the blockchain network) it registers them to the system as well. The system ensures only those whose student number are registered can register their address.
3- When the admin registers the students addresses, it also allocates a fixed number of tokens (e.g. 10) to each.
4- Amin can also send additional tokens to students when needed.
Student:
1- Those students who enrolled in the course and have enough tokens can send tokens to each other. This creates a transaction.
2- Both sender and receiver of tokens can leave feedback, or give score, to each other. The score ranges in [-5,5].
3- Students can see the list of transactions they been involved in (this will be done via UI).
Smart contract stores:
1- Valid students’ numbers
2- Valid students’ addresses
3- Valid admin address
4- Token balance of each student
5- Total number of transactions made by each student. It includes the total number of tokens sent and received by the student.
6- Each token transaction in detail, i.e. who send how many tokens to whom for what reason.
7- Valid student’s reputation.
