Opportunities and Challenges of Applying Blockchain Technology at Airports

Abstract

The outbreak of the Covid-19 pandemic has attracted more attention and highlighted the value of public health as well as the need for safe travel. When it comes to the tourism industry affected by the pandemic, the current global situation requires market transformation and innovation in the function of renewing tourist travel. Blockchain technologies in air transport are directing their business solutions towards the most promising opportunities and possibilities of application of this modern technology, now with a focus on overcoming the impact of the Covid-19 pandemic on business in the tourism industry. Blockchain-based applications have the potential to improve the user experience in the process of tracking luggage and goods, tracking the health of passengers, managing digital currency for the purchase of airline tickets, passenger identity management, loyalty programs, and more. Blockchain technology has already found application in financial management, storage and management of our personal data and information through a chain that is interconnected in time as a distributed book that records transactions between the parties involved, securely and permanently. This paper aims to present the possibilities of Blockchain technology and contribute to raising awareness of the great potential of application in the business of the airport within the tourism industry.

SOTF: Secure Organizational Transactions Framework Based on Bitcoin Payment Bridge

“…In bitcoin scripting language, Alice creates a transaction to pay to Bob that signs prior sending it to him. There are different types of blockchains [12,13,14,15]:1) Public blockchain as bitcoin and Ethereum [16,17,18] where anyone can make a transaction and access the block, but the problem is transaction expansion and speed delay. 2) Private chain in which one management entity can control and have the authority for all the chain service.…”

“…Else if index divided by 2 is equal to 1 then Pins is of type "Eight" Else if index divided by 2 is equal to 2 then Pins is of type "Twelve" Else Pins is of type "Fourteen" End if Call Remove Products function passing gate, pins, and number of items from above. End for Emit event to show that given number of items were removed from the supply chain due to being defectiveThe bridging transaction contract algoritms are given in Algorithms(9)(10)(11)(12)(13)(14); every transaction is characterized by the following data organized into a struct: 1) Transaction state is shown in Algorithm 9, 2) A list of items Ids is created in Algoritm 10, 3) A total amount due (in cents) for all the items in the cart, 4) A list of 3 dates (creation date, completion/payment date, refund date) is created, 5) Seller's signature of approval shown in Algorithm 11, 6) Buyer's signature of approval shown in Algorithm 12.Algorithm 9. Create transaction -Creates a new transactionReceive receipt number as input Increment total number of transactions by one Set state of new transaction to "Created" Set first date of dates list for the new transaction as current block time Emit an event to signal a new transaction A list of items Ids is created in Algorithm 10 where transaction items list is mapped by the receipt number and item price is mapped by the receipt number, a total amount due (in cents) for all the items is added in the cart, and a list of 3 dates (creation date, completion/payment date, refund date) is created.For item price in input list of item prices Add item price to transaction total price mapped by the receipt number End for Emit an event to show that the transaction characterized by the given receipt number was updated with a new total.Seller's signature required for approval is shown in Algorithm 11 in which seller signs the request, then the request is sent by bridging to buyer.…”
