Kwelichain

Problem Statement

Fraudulent certificates and forged credentials cost organizations over $40 billion annually worldwide. With the rise of AI-driven scams, document forgery is becoming cheaper, faster, and harder to detect growing by nearly 30% year-over-year.
Current verification systems are manual, slow, and expensive, creating bottlenecks for universities, professional boards, healthcare institutions, and government agencies.

Solution

Kwelichain provides a blockchain-based certification and fraud prevention platform that ensures documents are:

• Issued on-chain with tamper-proof metadata

• Role-based with issuer and admin controls

• Revocable in case of compromise or fraud

• Verifiable in real time by anyone, anywhere

We built Kwelichain on Curvegrid MultiBaas for seamless deployment, Hardhat + Solidity for smart contracts, and a React + Vercel dashboard for certificate issuance & verification.

Core Features (v1.0.0)

• Certificate issuance and validation on blockchain

• OpenZeppelin AccessControl for secure role management

• Revocation mechanism for compromised or invalid certificates

• IPFS support for metadata storage

• REST API for backend integration

• Modern React dashboard deployed on Vercel
  
  Impact & Differentiation

  • Cuts verification costs by up to 70% compared to manual processes.

  • Prevents duplicates and tampering with hash checks on-chain.

  • Unlike traditional PDF verification, Kwelichain offers real-time blockchain validation.

  • Positioned to scale into ID verification (Gov’t IDs, biometrics) and AI-driven fraud detection.
