# TODO

### DESCRIPTION

The Todo Contract is a simple implementation of a todo list where tasks can be added, completed, and fetched. Only the contract owner has the authority to perform these actions. A mapping called Tasks stores tasks and assigns them a task number. The completion status of each task is stored in a separate mapping called completedTask.

### FUNCTIONS

1. **addTask:** Adds a task to the to-do list. It takes a task description and a task number as input parameters. Only the contract owner can add tasks. Emits a taskAdded event.
2. **completeTask:** Marks a task as completed. It takes a task number as an input parameter. Only the contract owner can complete tasks. Emits a taskCompleted event.
3. **getTask:** Retrieves the description of a specific task based on the task number. It takes a task number as an input parameter and returns the task description.
4. **owner()**
5. **completedTask()**

### EXTRA PARAMETERS

**Contract Level:** Easy

**Utility Tags:** Todo, Task, Complete Task

### USES

1. **Personal Task Management:** The Todo contract can be utilized as a personal task management tool, allowing individuals to add tasks, mark them as completed, and keep track of their progress. It provides a decentralized and immutable record of tasks, ensuring transparency and accountability.
2. **Team Collaboration:** In a collaborative environment, such as a project team or a household, the Todo contract can facilitate task management and coordination. Team members can add tasks, update their completion status, and retrieve task details. This promotes transparency, accountability, and efficient collaboration within the team.
3. **Workflow Management:** The Todo contract can be integrated into larger workflow management systems. For instance, in a supply chain management system, different entities involved in the supply chain can utilize the contract to track and manage specific tasks or milestones. This enhances visibility, traceability, and efficiency in the overall workflow.
4. **Decentralized Project Management:** Decentralized project management platforms or decentralized autonomous organizations (DAOs) can utilize the Todo contract to enable task management within the decentralized ecosystem. Participants in the network can add tasks, track their completion, and contribute to the progress of the project or organization.
5. **Blockchain-Based Ticketing System:** The Todo contract can be extended to create a blockchain-based ticketing system. It can be used to manage and track the progress of support tickets, bug reports, or feature requests in a transparent and auditable manner. Users can submit tickets, update their status, and retrieve relevant information, promoting efficient issue resolution.
