# Goa GEL - Quick Start Guide
## 🚀 5-Minute Overview
The **Goa Government E-License (GEL) Platform** is a blockchain-based document verification system that enables multi-department approval workflows for government licenses using:
- **Hyperledger Besu** (blockchain)
- **NestJS** (backend API)
- **Next.js** (frontend)
- **PostgreSQL** + **MinIO** (data storage)
- **QBFT Consensus** (4 validators)
- **ERC-721 Soulbound NFTs** (license certificates)

**Key Components**:
- Frontend: React UI for users
- Backend: NestJS for business logic
- Database: PostgreSQL for structured data
- Cache: Redis for real-time state
- Storage: MinIO for documents
- Blockchain: Besu for immutable records

## 🔄 License Approval Flow (11 Steps)
```
1. Citizen Creates License Request
└─> Upload documents (PDF, images, etc.)
2. Documents Hashed
└─> SHA-256 hash of each document
3. Blockchain Recording
└─> Hash recorded on Besu (QBFT consensus)
4. Route to Departments
└─> Tourism + Fire Safety (parallel)
5-6. Departments Receive Notifications
└─> Ready for review
7-8. Departments Approve (Parallel)
└─> Record approvals on blockchain
9. NFT Minting
└─> ERC-721 Soulbound license certificate
10. Notifications Sent
└─> Citizen receives approval
11. Verification
└─> Anyone can verify on blockchain
```

## ⛓️ Blockchain Details
### Consensus
- **Type**: QBFT (Quorum Byzantine Fault Tolerant)
- **Validators**: 4 nodes
- **Requirement**: 3/4 (75%) agreement
- **Block Time**: ~12 seconds
- **Network**: Private permissioned
### Smart Contracts (4)
| Contract | Purpose | Key Functions |
|----------|---------|---|
| LicenseRequestNFT | Issue licenses as NFTs | mint(), burn(), ownerOf() |
| ApprovalManager | Record approvals | recordApproval(), getApprovalChain() |
| DepartmentRegistry | Manage departments | registerDept(), setApprovers() |
| WorkflowRegistry | Define workflows | defineWorkflow(), getWorkflow() |
### Data Strategy
**On-Chain** (Immutable & Verifiable):
- License hashes
- Approval signatures
- Department registry
- NFT ownership
**Off-Chain** (Searchable & Scalable):
- Full document details
- Applicant information
- Actual document files
- Workflow state
**Link**: SHA-256 hash bridges both worlds
