Decentralized finance (DeFi) is an emerging financial technology
based on secure distributed ledgers similar to those used by
cryptocurrencies.
In the U.S., the Federal Reserve and Securities and Exchange Commission (SEC)
define the rules for centralized financial institutions like banks and
brokerages, which consumers rely on to access capital and financial services
directly. DeFi challenges this centralized financial system by empowering
individuals with peer-to-peer transactions.(資料來源 )
Virtual reality (VR) is a simulated
experience that employs pose tracking and 3D near-eye displays to give the user
an immersive feel of a virtual world. Applications of virtual reality include
entertainment (particularly video games), education (such as medical or military
training) and business (such as virtual meetings). Other distinct types of
VR-style technology include augmented reality and mixed reality, sometimes
referred to as extended reality or XR, although definitions are currently
changing due to the nascence of the industry.(資料來源 )
