Create Classes
Instructors can generate unique class spaces that automatically bind rosters, quizzes, and attendance checks to the same secure ledger.
Secure, Zero-Knowledge Polling for the Classroom
Quizzy 499 is a proof-of-concept platform that protects in-class polls from tampering by blending blockchain storage with Zero-Knowledge Proofs. Students verify their identity without exposing private data, keeping every response auditable and anonymous.
Problem Space
Eliminates cheating in rapid-fire classroom polls and attendance checks.
Integrity Layer
Zero-Knowledge verification validates identities without revealing them.
Deployment
Hosted on Replit with persistent data backed by Replit DB.
Core Classroom Features
Quizzy 499 was designed alongside educators to balance classroom usability with uncompromising security. The feature set streamlines administration while ensuring every submission remains verifiable.
Lifecycle Management
Archiving or deleting classes safely retires their on-chain state while preserving the audit trail for compliance and accreditation.
Quiz Builder
Teachers craft rapid assessments with configurable answer formats. Each quiz inherits the same tamper-resistant submission pipeline.
Student Enrollment
Students join quizzes with invite codes tied to their Zero-Knowledge credentials, guaranteeing that only authorized participants submit answers.
Identity Verification
The authentication flow issues cryptographic proofs that confirm a student’s legitimacy while shielding personal details from instructors and peers.
Dual-Sided Access
Separate teacher and student portals highlight the actions each role needs, keeping sensitive administrative controls locked behind elevated credentials.
Technology Stack
A lightweight architecture keeps development nimble while enabling cryptographic rigor. Each component was selected for developer velocity, verifiability, and frictionless deployment.
Replit Platform
Cloud-hosted IDE with live collaboration powers rapid prototyping, preview deployments, and automated builds so the team can iterate in the browser.
Replit DB
Persistent key-value storage retains quiz metadata, rosters, and proof references without the overhead of managing a separate database service.
Flask Microservices
Python-based APIs orchestrate the Zero-Knowledge workflow, serve the front-end, and broker requests to the blockchain layer with minimal latency.
Product Walkthrough
From set-up to quiz submission, each screen leans on bold typography and contrast so instructors can focus on students, not UI friction.
Teacher Console
Quick stats for active classes, attendance metrics, and poll readiness give educators the confidence to launch real-time assessments.
Quiz Creation
Guided forms capture prompts, options, and scoring rules while automatically binding them to the selected class and blockchain ledger entries.
Student Login
Learners authenticate with wallet-backed credentials, receive a signed proof, and are dropped straight into the quiz lobby without leaking private data.
