blockchains and tickets
it is fairly common, when going to an event - to be asked to buy a ticket for entering the space. A film, a festival, an exhibition, a show, and such like - stuff that's made from, by, through and for culture - tend to require some kind of a value exchange. Give some number value that can be exchanged with some other stuff - and get to experience stuff like a film in a cinema, a show, and so on.
