Description

๐Ÿพ PetLog โ€“ Blockchain Pet Identity Platform

"Every pet deserves a verified story."

PetLog is a Web3-based decentralized biodata system for pets, built to store and verify lineage, vaccination, and health records on-chain.
By connecting breeders, veterinarians, and owners through validator-based smart contracts, PetLog eliminates fake certificates and fragmented data โ€” creating trust, transparency, and traceability across the global pet ecosystem.

PetLog revolutionizes pet ownership verification by creating immutable, blockchain-based digital identities for pets. Built on Cardano Pre-Production testnet, each pet receives a unique NFT passport containing verified lineage, health records, and ownership history.

Hackathon Project: Building trust in pet ownership through decentralized digital passports on Cardano


๐ŸŽฏ Problem Statement

  • 42% of pedigree certificates in Asia are unverifiable (Asian Kennel Network, 2024)

  • 73% of veterinary clinics in Indonesia use manual records (Indonesian Veterinary Association, 2023)

  • No standardized system for pet data verification across developing markets

๐Ÿ’ก Solution: Decentralized Trust Layer

PetLog creates a blockchain-based trust network where:

  • ๐Ÿงฌ Immutable Lineage Records from certified breeders

  • ๐Ÿ’‰ Verified Health Logs digitally signed by veterinarians

  • ๐Ÿชช NFT Pet Passports that travel with ownership transfers

  • ๐Ÿ”— Validator Network of trusted pedigree associations and clinics

โœจ Key Features

  • ๐Ÿ” Wallet Integration: Seamless connection with Cardano wallets (Nami, Eternl, Gero, Flint)

  • ๐ŸŽจ Guided Minting Flow: Intuitive pet passport creation with IPFS asset storage

  • ๐Ÿ“ฑ Personal Gallery: View all owned pet passports with metadata resolution via Blockfrost

  • ๐Ÿ” Passport Details: Complete pet profiles with explorer links and provenance tracking

  • โšก CIP-25 Compliant: Following Cardano NFT metadata standards

  • ๐ŸŒ IPFS Integration: Decentralized storage via Pinata for pet photos and documents
