Project description

Event ticketing allows event organizers to create custom EVENT tickets to SELL for their events.

Event organizers create an event and specify max number of attendees along with other informations. Attendees puchase event tickets with the event is yet to expire. Event tickets funds accumulate in escrow of the event creator which can be withdrawn at any time. Event moderators can verify that an attendee has purchased a ticket just by querying the contract with the address of the attendee. Event moderators can update the state of event to "expired", after which attendee(s) will not be able to puchase tickets.

• Attendees can proof they purchased a ticket by showing ownership or presenting the address they used to purchase the ticket.

Simple workflow

1. Enter service web site
2. Login with Metamask
3. Select event you want to purchase ticket for.
4. Pay for ticker to event.
5. Event creators have a separate page to create event with details.
