Jack Dorsey is the co-founder of Twitter and Square (now Block), a Bitcoin maximalist, and one of Silicon Valley's most enigmatic figures. He sent the first-ever tweet, built a payments empire, walked 5.3 miles to work daily, meditates two hours a day, eats once a day, and is currently obsessed with decentralizing everything from money to social media. His latest ventures - Bitchat (Bluetooth mesh messaging) and Block's Bitcoin treasury - reveal a builder who has moved far beyond the platforms that made him famous.
