Yet another powerful project of blockchain technology, particularly Ethereum. Building such a system for a huge industry like travel has the potential to completely revolutionize the entire trip-planning process, from booking flights to choosing where to have dinner that night. I love that Triip aims to give that power to the locals, allowing for a universal currency and rewards system that makes the process easier for everyone while taking the advantage away from larger institutions. Even just from the perspective of supporting small businesses, this is huge.
