For safe use of digital badges, blockchain technology is generally utilized. However, blockchain requires significant costs and has a high level of complexity for building the necessary infrastructure. This paper proposes the use of JWT (JSON Web Tokens) to complement the shortcomings of blockchain. The system flow for utilizing JWT-based digital badges in a real web environment is designed. To compare the performance of JWT and blockchain, the time complexity for issuing and verifying digital badges in each method was analyzed. While the time complexity for verification was O(1) for both methods, the time complexity for issuance differed: JWT was O(1) whereas blockchain was O(V), Therefore, JWT proved to be faster in the issuance process.

摘要

For safe use of digital badges, blockchain technology is generally utilized. However, blockchain requires significant costs and has a high level of complexity for building the necessary infrastructure. This paper proposes the use of JWT (JSON Web Tokens) to complement the shortcomings of blockchain. The system flow for utilizing JWT-based digital badges in a real web environment is designed. To compare the performance of JWT and blockchain, the time complexity for issuing and verifying digital badges in each method was analyzed. While the time complexity for verification was O(1) for both methods, the time complexity for issuance differed: JWT was O(1) whereas blockchain was O(V), Therefore, JWT proved to be faster in the issuance process.
