🎯 PoArt Protocol Philosophy

Culture > Capital

This is not slowness.
This is civilization.

Core Principles:

• ✅ 365-day continuous cold wallet storage requirement
• ✅ Anti-speculation through temporal commitment
• ✅ Millennium-scale authentication (2025-3000)
• ✅ Mathematical resistance to flash loans & whale dominance
• ✅ Cultural preservation over capital accumulation

🔐 Authentication Features

Each artwork receives:

Digital Authentication

• ✅ Unique Artwork ID: Format: ARTISTNAME_YEAR_XXX
• ✅ SHA-512 Cryptographic Hash: 128-character hexadecimal
• ✅ QR Code Verification: Instant mobile authentication
• ✅ JSON Metadata: Complete provenance and authentication data
• ✅ Dual Hash System: Original + Watermarked verification

Visual Watermark

┌─────────────────────────┐
│     [QR CODE]           │  → Verification URL

Design Features:

• Premium green glassmorphism (#10b981)
• Semi-transparent overlay with blur effect
• Bottom-right positioning with 20px padding
• High-quality QR code (Error Correction Level H)

---

🚀 Quick Start

Verify an Artwork

1. Locate the artwork in the appropriate artist directory
2. Scan QR code on the watermarked image
3. Visit verification URL: https://www.ilhanart.org/verify?id=ARTWORK_ID
4. Compare SHA-512 hash with your file
5. Check JSON metadata for complete provenance

Calculate SHA-512 Hash

# Linux/Mac
shasum -a 512 artwork_file.png

# Windows PowerShell
Get-FileHash -Algorithm SHA512 artwork_file.png

Search Authenticated Artworks

# Find specific artist
cd artists/ali-naki-ilhan/

# Search in master record
grep "ILHANART_2025_001" MASTER_AUTHENTICATION_RECORD.csv

🛠️ Development

Prerequisites

• Python 3.8+
• Pillow (PIL)
• qrcode
• hashlib (built-in)

Installation

Verify Artwork Programmatically

import hashlib

def calculate_sha512(file_path):
    """Calculate SHA-512 hash of a file"""
    sha512 = hashlib.sha512()
    with open(file_path, 'rb') as f:
        while chunk := f.read(8192):
            sha512.update(chunk)
    return sha512.hexdigest()

# Example usage
hash_value = calculate_sha512("artists/ali-naki-ilhan/01_originals/ILHANART_2025_001_original.png")
print(f"SHA-512: {hash_value}")
