A person is using a smartphone on top of a patterned surface. The screen of the phone displays a black interface with a colorful logo at the top, along with text that reads "Collective Memory," "Latest Top Staked Memory," and "DAILY CHALLENGE: Tradition. Represent your culture." The person's finger is repeatedly tapping on a colored box within the app interface. As the finger taps, the color of the box changes. A notification appears at the bottom of the screen that reads "10000 pATTN staking..." The overall setting appears to be an indoor environment.
