Statistics from the National Bureau of Statistics show that our annual domestic tourist arrivals and tourism revenue have maintained a growth level of more than 10% each year. The tourism industry has always been a key industry in my country. However, false ticket purchases have been repeatedly banned and even more rampant. Many anti-counterfeiting methods have emerged with the advancement of technology, but there are still many false bills. So, in a world where even US dollars can be forged, can real technology guarantee 100% genuine tickets? The answer is: Blockchain Tickets Blockchain tickets are electronic tickets issued using blockchain technology. The blockchain has the properties of decentralization and non-tampering, ensuring that the tickets are 100% genuine. Although my country has not yet used the blockchain to solve the problem of the ticketing industry, other countries have begun research and experiments on solutions to this problem. Ticket problems do not only exist in our country. People in other countries will also encounter troubles such as ticket fraud. In terms of technical architecture, "tickets on the chain" still belong to the application of blockchain electronic invoice technology. When tourists purchase electronic tickets, the system will automatically issue an electronic invoice to facilitate tourists' reimbursement. This solves the trouble that tourists still need to issue tickets offline after purchasing electronic tickets in the past. The combination of electronic tickets and electronic invoices facilitates tourists' travel. In the larger ticket market, blockchain technology is equally promising. In the ticketing industry, electronic tickets use dynamic QR code technology to ensure that the person who enters the venue is the ticket buyer himself, which solves the problem of fraudulent paper tickets. However, the dynamic QR code also restricts the resale of tickets. The resale of e-tickets is still very difficult. Although the exploration of blockchain in the tourism industry is still in its early stages, in the future, there may be more surprises that will arise between the two collisions.
