Block, the fintech company founded as Square in 2009, has grown into a broad payments and digital infrastructure business under the leadership of CEO Jack Dorsey, whose net worth reached an estimated $4 billion in 2025. The company now supports more than four million sellers and processes over $241 billion annually, a scale far beyond its original point-of-sale offering.
Dorsey reinforced his long-term commitment to decentralised technology after rebranding the company to Block in 2021, steering it deeper into Bitcoin development. At the Bitcoin Vegas conference, the company confirmed it would enable merchants to accept Bitcoin through its POS hardware, marking another step in its payment strategy.
Dorsey’s activity outside Block follows a similar interest in alternative digital systems. He launched Bitchat, a Bluetooth-based messaging app that works without cellular or internet access, and put funding behind groups working on open-source social networking protocols. These projects sit alongside his ongoing commitments inside Block, where Bitcoin integration continues to expand, including payment acceptance for merchants through existing POS hardware.
Market reactions have been mixed—shares rose after S&P 500 inclusion, yet concerns about earnings and Bitcoin volatility remain. Even so, Block continues to invest in hardware, payments, and software that support Dorsey’s broader push toward decentralized tools and long-term infrastructure development.
