PROJECT NAME (SkillProof)
=====================================================
AI + Blockchain Hiring Trust Platform
"The Trust Layer for Remote Hiring"

=====================================================
CORE IDEA
=====================================================
A platform that verifies real skills of developers and freelancers using AI-driven interviews
and stores verified proof on blockchain for tamper-proof trust.

Think:
LinkedIn + GitHub + AI Interviewer + Blockchain Credential

=====================================================
TARGET USERS
=====================================================
1. Candidates (Developers / Freelancers)
2. Employers (Startups / Companies)

=====================================================
PROBLEM STATEMENT
=====================================================
- Fake resumes and fake experience
- No trusted way to verify remote candidates
- Manual hiring is slow and expensive
- Freelancers cannot prove real skills
- Employers lose money on bad hires

=====================================================
SOLUTION
=====================================================
An AI-powered skill verification system where:
- AI conducts coding interviews
- Skills are scored objectively
- Verified skills are minted as blockchain credentials (NFTs)
- Employers can instantly verify trust

=====================================================
MVP FEATURES (30–45 DAYS)
=====================================================

-------------------------
Candidate Features
-------------------------
- Email / Wallet login
- Profile creation (skills, resume, GitHub)
- AI coding interview (text-based)
