Explaining financial technology sometimes works best when it comes from practitioners with a vested interest in, as well as a passion for, the topic. Glossary reports on industry players' own versions of these technologies, because they can be both more colorful and a little easier to understand than a dry, technical description. Readers should be aware, therefore, that these accounts will be self-serving. DigFin welcomes suggestions to add to or amend Glossary articles. Please contact us at glossary@DigitalFinanceMedia.com.
