  In this paper, we developed a blockchain application to demonstrate the
functionality of Sui's recent innovations: Zero Knowledge Login and Sponsored
Transactions. Zero Knowledge Login allows users to create and access their
blockchain wallets just with their OAuth accounts (e.g., Google, Facebook,
Twitch), while Sponsored Transactions eliminate the need for users to prepare
transaction fees, as they can delegate fees to sponsors' accounts.
Additionally, thanks to Sui's Storage Rebate feature, sponsors in Sponsored
Transactions can profit from the sponsorship, achieving a win-win and
sustainable service model. Zero Knowledge Login and Sponsored Transactions are
pivotal in overcoming key challenges novice blockchain users face, particularly
in managing private keys and depositing initial transaction fees. By addressing
these challenges in the user experience of blockchain, Sui makes the blockchain
more accessible and engaging for novice users and paves the way for the broader
adoption of blockchain applications in everyday life.
