Dorsey has spent the last five-odd years fascinated with cryptocurrency and blockchains, primarily Bitcoin. He has heavily promoted and supported the development of the Bitcoin Lightning Network, and supported Bitcoin developers directly through a unit called Square Crypto (which will now be renamed, rather awesomely, Spiral). He added Bitcoin functionality to Square’s Cash App. At Twitter, he recently rolled out Lightning-based tipping, and before stepping down promised NFT (non-fungible token) avatar integration.
