For the simplest and most comprehensive view, we can look at the following example: Tom has a flight from Berlin to Seoul and luggage empty 5kg of portable. Maria living and working in Berlin want to send her friend in Seoul a 5kg gift parcel. If Maria sent by conventional means of transport such as DHL, GRS, etc. the cost is quite high and the waiting time is long. Maria and Tom meet and exchange their needs at the Airchain ecosystem. And just the next day, Maria’s package arrived at his friend’s best cost, safely and quickly. And Tom, he has more income without any effort due to the sale of his empty baggage. At the same time, his credibility at Airchain was one level higher after successful transactions.
