*1.2.3 Transaction-oriented platform*

Platforms provide a technical architecture to combine supply generation and transaction execution with different units of value. Platforms create frameworks through defined functions and mechanisms. These types of platforms greatly reduce transaction costs while facilitating the parties involved in transactions. Many platforms act as focal points, combining supply and demand, and increasing efficiency for stakeholders. Popular examples of businesses operating trading platforms are Grabfood (food delivery), eBay (used goods), and SoundCloud (audio files).
