The Course Enrollment Contract handles the enrollment process for courses within the Knowledge Ledger ecosystem. It ensures that students meet prerequisites, validates payments, and grants access upon successful enrollment.
Input: John enrolls in Course 1 (Advance Haskell) after confirming prerequisites.
Output: John successfully enrolls in the course; his enrollment status and completed courses are updated.
Mechanism: The code validates prerequisites, enrolls users, updates their records, and confirms successful enrollment.
This contract facilitates revenue sharing between content creators and Knowledge Ledger, ensuring that instructors receive fair compensation for their contributions. The contract enforces predefined terms and conditions for royalty distribution.
Input: Number of content creators, their names, and respective royalty percentages,Prize.
Output: Royalty distribution as a list of tuples containing creator names and their calculated royalty shares.
Mechanism: The code takes inputs for the number of content creators, their names, and royalty percentages. It then calculates the royalty distribution based on the provided percentages, and outputs a list of tuples representing the distribution.
The Learning Progress Tracking Contract records and tracks the progress of learners, including completed modules, assessments, and achievements. This transparent record of accomplishments encourages learners to stay engaged and motivated.
Input: User's learning data including completed modules, assessments, and achievements.
Output: LearningProgress object containing a summary of the user's progress and achievements.
Mechanism: The code collects and organizes user input regarding completed modules, assessments, and achievements, then constructs a LearningProgress object to present the user's learning journey.
The Tokenization Contract converts certificates or credentials earned through Knowledge Ledger into unique tokens on the blockchain. These tokens provide a tamper-proof way to verify and transfer certifications, making them more portable and accessible.
Input: User's name, number of completed courses, course IDs and names, certificate ID.
Output: Tokenized certificate information containing owner name, course details, and token ID.
Mechanism: The code tokenizes completed course information and certificate ID to generate a unique token with relevant course and user details.
The Certificate Issuance Smart Contract on the Knowledge Ledger platform is a cutting-edge solution that automates and streamlines the process of issuing educational certificates. Built on the secure Cardano blockchain, this smart contract ensures tamper-proof verification and transparency in credentialing.
Input: User's username, Certificate ID (700), Course name (Basic Haskell), Token for Course (Data Structures)Output: Certificate issued confirmation for the user (jack123) upon completing the course (Basic Haskell), with instructions to view and download the certificate from their profile.Mechanism: The code takes user inputs, validates completion of the course, generates a certificate, associates it with the user's profile, and provides instructions for accessing the certificate.

This guide will walk you through the process of running a Haskell project using Cabal. We'll assume that you have cloned the repository containing the project source code.
First, clone the repository containing the Haskell project source code. You can do this by using the following command:
https://github.com/KonmaLabzIO/nuveda
Navigate to the project directory and initialize the Cabal configuration. Cabal is a build tool for Haskell projects that helps manage dependencies and build processes. Run the following command:
cabal init
This command will guide you through the process of creating a .cabal file, which contains project configurations and metadata.
Once the .cabal file is generated, you can build the project by executing the following command:
cabal build
This command will compile the project source code and create executable files.
You can also use the cabal run command to both build and execute the application. This command simplifies the process:
cabal run
Running this command will build the application, reveal executable links, and then execute the application, displaying its output.
