Why does GIWA need Dojang and Bojagi?

Sometimes you need to prove your qualifications to use a service, but you don't want to disclose all your personal information. GIWA introduces Dojang and Bojagi, which address these information disclosure issues in authentication and transactions, respectively.

Dojang is a service that verifies necessary credentials or status. It links information confirmed by trusted institutions to a wallet address, making it verifiable on-chain. This approach allows you to utilize verification results without directly revealing personal identifiers like your name.

Bojagi focuses on protecting transaction information. It is designed to verify the validity of transactions without exposing sensitive data on-chain by leveraging zero-knowledge proofs. Zero-knowledge proof is a technology that verifies specific facts without revealing the underlying details.

The key feature here is the distinction between necessary verification data and public information.
