Eventsafe

Eventsafe is a decentralized ticketing platform dedicated to privacy protection, committed to providing users with a secure and confidential ticket purchasing and trading experience.

Issues:

We focus on the privacy of users and event organizers participating in or hosting gatherings. Currently, users often need to provide personal identification, such as their real names, email addresses, or phone numbers, to purchase tickets for events like concerts or sports games. This information is sometimes required to register an account with various entities, including telecommunications companies, ticketing agencies, and email providers. Consequently, users' data becomes accessible to multiple organizations, leading to concerns about credit and privacy breaches. This is especially crucial for celebrities, as seen in previous incidents like the leakage of photos of the Korean star Lisa attending a show, resulting in her being subjected to harsh criticism from fans. For ordinary individuals, the consequences include receiving targeted advertisements based on the leaked information and occasionally encountering photos of themselves in awkward or unflattering poses posted by others with no means to control their dissemination.

Our Core Functions:

Before the event:

1. Event organizers can initiate events anonymously, and users can participate using invitation codes, ensuring the privacy of the event while also protecting the organizer's identity.
2. Users can conduct ticket transactions on our platform without needing to know the specific details of the event organizer, thus safeguarding their own privacy.
3. Upon entering an invitation code provided by the user, we generate a QR code for them. Event organizers can then scan this QR code to verify the user's ticket purchase and grant access to the venue.

After the event:

1. When users post photos on social media after the event, we employ an innovative facial recognition mechanism. By comparing faces in the photos with our database, if other individuals' faces are detected, we notify the corresponding event participants to seek permission for photo publication. If permission is denied, we intervene to prevent the photo from being posted.

Technologies Utilized:

we mainly use Oasis network?

### Confidential network

 We store our credential mappings directly in contract storage, and it's encrypted and safe naturally.  

### Sapphire.randomBytes() 

We utilize the Sapphire.randomBytes() function to generate our core IDs, such as ticket ID and invitation code.   

### Gas-free transaction

We let attendees pay just once for an event when they checkout, and for the following smart contract interactions we'll just utilize the gas-free transaction to pay the gas with the balance in the contract.
