Travala is a good example that you mentioned, I even have a few of these AVA tokens, there are probably some similar projects that have recognized the vision of the future in this area, know a few of them. That's so true, the travel industry is just one example! Most of the points could of course also be of interest to other industries, there are numerous model projects that are already taking place in this area, most well-known in probably the banking sector in which the largest growth can currently be seen when it comes to implementation in large capitalist structures. It's a completely different topic, of course industry branches will follow and work on blockchain solutions in addition to the current digitization.
