## 5 Conclusions  
This study utilized the craftwork attribute classification system to generate a unique digital fingerprint of a craftwork by applying hash functions, enabling the original authentication of the craftwork. Additionally, by applying consortium blockchain technology that allows various craft-related organizations to collaborate, a blockchain transaction system for authenticating original crafts was developed that automatically generates a smart contract upon the occurrence of a transaction, stores it on the blockchain, and tracks and manages the transaction history. Furthermore, DApp was developed, which enables buyers to verify craftwork authentication information and transaction histories by scanning the digital fingerprint of the craftwork through interworking with this system. The integration of digital fingerprints and blockchain technologies has resulted in the creation of a secure and transparent craftwork transaction system that guarantees both security and efficiency. The system met with approval from those in the craft industry. Craftsmen particularly noted that the system's greatest advantage is its ability to systematically register information about craftwork items by categorizing them by attributes such as color and material, thereby creating a unique digital fingerprint. They indicated that this feature could serve as an effective tool for clearly differentiating between genuine and counterfeit or imitation items and that, unlike complex and often ineffective design patents, this easy and \begin{table}
