A Stateful Proof of Attendance Protocol (POAP) system operates by maintaining and utilizing state information to track and verify user attendance at events. This state information is crucial for ensuring the integrity, reliability, and personalization of the POAP tokens issued to attendees. Here’s a detailed explanation of how a stateful POAP system works:
Users register for events, and their identities are recorded in the system. This can involve creating unique user IDs, which are used to track their attendance and participation.
The system keeps a record of all events and the corresponding attendees. When a user attends an event, this information is added to their state, updating their attendance history.
Upon verification of attendance, the system issues a POAP token to the user. This token is a unique, non-transferable digital badge that serves as proof of their participation in the event.
The system maintains a persistent state for each user, which includes their attendance history, issued POAP tokens, and any other relevant information. This state is stored securely and can be accessed and updated as needed.
The stateful system ensures that each POAP token is linked to a verified event attendance. This prevents fraud and ensures the authenticity of the tokens. Users can present their POAP tokens as verifiable proof of attendance.
