Rankify

Rankify is a blockchain-enabled competitive programming platform focused on trusted skill assessment, transparent rankings, and proctored coding challenges. It combines a modern contest interface, an integrated coding IDE, and an on-chain ranking system built on Aptos Move.

Key Highlights

• End-to-end contest journey: discover challenges, register, launch IDE, solve problems, and track progress.
• Integrated coding environment with multi-language support and test execution.
• Proctoring controls for exam integrity (fullscreen enforcement, shortcut blocking, violation tracking).
• Smart-contract-based ranking records and user rank management on Aptos.
• Centralized data and launch controls for challenge visibility and release scheduling.

Core Features

Contest Platform

• Active, upcoming, and historical challenge views.
• Challenge registration flow with status transitions (upcoming/live/completed).
• Registered challenge tracking with progress indicators.
• Rich challenge metadata including prize pools, tags, and rules.

Integrated IDE

• Problem list and challenge-based problem mapping.
• Multi-language coding support (Python, JavaScript, Java, C++).
• Test-case execution with pass/fail feedback.
• Code complexity and performance estimation during evaluation.

Proctoring Layer

• Fullscreen enforcement and focus-loss detection.
• Keyboard shortcut restrictions for common cheating vectors.
• Right-click/context menu suppression in exam sessions.
• Violation logging with user-facing warning prompts.

On-Chain Ranking System (Move Contract)

• Add users and update ranks via transaction entry functions.
• Query user profile and existence through view functions.
• Retrieve total user counts and recent user IDs.
• Search helpers for rank range, contest name, and skill tags.

Getting Started

Prerequisites

• Node.js 18+
• npm
• Aptos CLI (required for Move compile/test/publish workflows)

1. Install Dependencies

npm install

2. Configure Environment Variables

Create a .env file in the project root and set the values below.

VITE_APP_NETWORK=testnetVITE_APTOS_API_KEY=your_aptos_api_keyVITE_MODULE_ADDRESS=your_published_module_addressVITE_MODULE_PUBLISHER_ACCOUNT_ADDRESS=your_account_addressVITE_MODULE_PUBLISHER_ACCOUNT_PRIVATE_KEY=your_account_private_keyVITE_RAPIDAPI_KEY=your_rapidapi_key

3. Run the App

npm run dev

4. Build for Production

npm run build

5. Lint

npm run lint

Move Contract Workflows

npm run move:init
npm run move:compile
npm run move:test
npm run move:publish
npm run move:upgrade

These scripts automate account/module setup, compile/test cycles, and publish/upgrade operations for the ranking_system Move module.

Routes

• / - Home and platform overview
• /contest - Active/registered challenge dashboard and IDE launch flow
• /leaderboard - Ranking and top performer views
• /profile - User profile and progress dashboard
• /ide - Standalone IDE experience

Deployment

• Frontend deployment target: Vercel (npm run deploy).
• Smart contract deployment helper: ./deploy.sh <aptos-profile-name>.

Notes

• This repository currently contains the frontend and on-chain module implementation. The backend/database stack shown in the Tech Stack section reflects the target service architecture used for platform integrations.
