The rename to Block reflects the company's expansion beyond Square's merchant services into Cash App (peer to peer payments), TIDAL (music), and TBD (decentralized finance with Bitcoin).

In interviews, showing that you think about how technology decisions impact real people, especially underserved populations, demonstrates mission alignment.
