Blockchain is the latest innovation to take over vacation planning. It’s expected to disrupt the industry as much as when Expedia, Airbnb, and Priceline took vacation planning online.
A company is attempting to apply blockchain to the travel industry. To be successful it needs to outcompete other entrenched rivals such as Expedia, Airbnb, and Priceline in a historically very low margin business. At the time of this writing, blockchain has not been found to be a competitive advantage in any industry outside of blackmarket transactions.
