i've try alpha platform, and how to check my ticket when i purchase some tickets? and, how to use the ticket after purchase it?
In future the ticket barcodes can be scanned, maybe a password or ID check also is associated with it. The event promoters will have different options on how they wish their tickets to be validated. Also tickets can be resold and refunded according to customizeable Smart Ticket rules.
But that still doesnt fix the reselling. Despite reputation system and pegging price of tickets, if just barcode will be used, than you can still print and sell the ticket for 200% profit. You wrote that it will be up to event promoters which system to use, but i think black market problem should be fought form the start of the chain and that will be your platform.
