DeFi, or decentralized finance, has become part of more and more company promotions this year. Nucleus Vision, a data-sourcing project started in 2014 to provide consumer insights to retailers, recently announced that it’s “DeFi for Retail Purchase Loans.” Tao Network, which has been around since 2015, now states it’s “building DeFi of entertainment.” Tron, an operating system active for at least three years, just issued its own DeFi coin.
