🏥 MedTasks – Decentralized Health Task Manager

MedTasks is a Solidity smart contract built for the healthcare industry to manage and track patient-related tasks on the blockchain. It enables healthcare workers to securely create, view, update, and delete medical follow-up tasks linked to specific patient IDs, promoting accountability, transparency, and data integrity in clinical workflows.

---

🔧 Features

• ✅ Task Creation: Add follow-up tasks tied to a patient's unique ID.
• 📋 Task Management: View, update, or delete only your own tasks.
• ⏳ Status Tracking: Tasks can be Pending, Ongoing, or Completed.
• 🕒 Timestamps: Each task records when it was created.
• 🔐 Access Control: Only the creator of a task can modify or delete it.
• 📡 Events: Emits events on creation, update, and deletion for frontend or audit integration.

---

🧱 Smart Contract Structure

• Enum: Status defines task state: Pending, Ongoing, Completed.
• Struct: Task includes patientId, description, status, and createdAt.
• Mapping: tasks[address] stores each user's tasks privately.
• Functions:
  • createTask(...)
  • getMyTasks()
  • getTasksByWorker(address)
  • updateTask(...)
  • deleteTask(...)
• Events:
  • TaskCreated
  • TaskUpdated
  • TaskDeleted
