■Conceptual diagram of system usage assumed in this use case
In the prototype for this project, screens will be created for the three roles of applicant, certifier, and applicant, and a series of application processes will be realized in conjunction with the Trusted Web Repository.
Implementation of Trusted Web Repository will be verified using public blockchain (Cardano), DID/VC (AtalaPRISM), distributed storage (IPFS), etc.
It is difficult to keep track of the current business status and existence of small and medium-sized corporations and sole proprietors, and for sole proprietors, it is difficult to even capture them. In this use case, we will create a new mechanism to clearly identify and prove the existence of small and medium-sized corporations and sole proprietors through Trusted Web technology, using information held by the government and credit information of financial institutions.
