Jack Dorsey

Jack Patrick Dorsey is an American internet entrepreneur best known for co-founding Twitter, Inc. (now X). Later, he founded Block, Inc. (formerly Square, Inc.), a financial services and payments company with a major focus on Bitcoin $0.0202 24h volatility: 1.0% Market cap: $20.21 M Vol. 24h: $1.93 M and crypto infrastructure. Over the past decade, Dorsey has become one of the most visible and persistent advocates for Bitcoin’s adoption, integration into mainstream financial systems, and transformation into a global, decentralized money system.

Dorsey’s recent work places crypto, particularly Bitcoin, at the center of his vision for the future of money and financial infrastructure. His leadership in building products that enable Bitcoin payments, investing in Bitcoin mining and infrastructure, and promoting self-custody solutions underscores his long-term commitment to decentralized, permissionless money and finance.

Early Life and Entrepreneurial Background

Jack Dorsey was born in St. Louis, Missouri, and showed early interests in programming and dispatch routing systems. He attended the Missouri University of Science and Technology and later New York University. However, he ultimately dropped out before graduating. Dorsey’s early interest in tech and communications laid the foundation for his role in the early social media era.

In 2006, Dorsey co-founded Twitter, one of the world’s most influential social platforms. He served as CEO during the company’s early years and again from 2015 to 2021. Dorsey led Twitter through major product expansions and global influence as a communications channel.

After stepping down as Twitter CEO in 2021, Dorsey focused full-time on his fintech company, Block, Inc., which he co-founded and now leads as CEO and Chairman.

Block and the Crypto Strategy

Square, Inc was founded in February 2009 by Dorsey and Jim McKelvey. Block grew from a simple mobile card reader startup into a broad financial ecosystem supporting digital payments, commerce tools, and crypto-native products.

Cash App and Bitcoin Integration

One of Block’s first major crypto breakthroughs came through Cash App (originally Square Cash), a peer-to-peer payments app launched in 2013 that added Bitcoin buying and selling functionality. As of 2026, Cash App reported over 24 million active users who had purchased Bitcoin on the platform, making it one of the largest retail platforms for Bitcoin adoption in the world.

Cash App’s integration of Bitcoin, including Lightning Network support for fast, low-cost transfers, positioned Block as more than a fintech company. It became a key bridge between everyday users and crypto markets.

Bitcoin Payments and Adoption Initiatives

Under Dorsey’s leadership, Block significantly expanded crypto capabilities across its merchant ecosystem:

• In 2025, Block enabled Bitcoin payments for more than 4 million Square merchants, allowing point-of-sale acceptance of Bitcoin and settlement via the Lightning Network. It was a major milestone for real-world Bitcoin use cases.
• Block also introduced products that allow merchants to automatically convert a portion of daily sales into Bitcoin. It enables businesses to incorporate digital assets into their revenue streams.

These initiatives reflect Dorsey’s philosophy of making Bitcoin a practical tool for commerce, not just an investment or speculative asset.

Bitcoin Infrastructure and Self-Custody Efforts

Beyond payments, Block has invested in infrastructure that supports decentralized Bitcoin ecosystems:

Bitkey Wallet

Block launched Bitkey, a self-custody Bitcoin wallet that enables users to store and manage their Bitcoin outside custodial platforms. Bitkey combines a hardware device, mobile app, and recovery tools designed to make secure Bitcoin ownership more accessible.

Bitcoin Mining and Proto

Block has also explored Bitcoin mining and hardware innovation. The company announced plans to build open-source Bitcoin mining systems and chips to decentralize hardware supply and reduce reliance on a small number of manufacturers.

These moves show a broad commitment to the entire Bitcoin stack — from end users to mining infrastructure — and support Dorsey’s narrative of Bitcoin as open, decentralized money.

Leadership Philosophy and Crypto Advocacy

Jack Dorsey has repeatedly stated that Bitcoin should be the “native currency of the internet” and has consistently promoted its principles of decentralization, censorship resistance, and economic freedom. In interviews and at major industry events, he has emphasized Bitcoin’s value as a hedge against inflation and as a decentralized monetary system for the global internet age.

Dorsey’s crypto advocacy extends beyond product releases. He has encouraged open-source development, engaged with Bitcoin communities and conferences (such as “The B Word”), and supported broader ecosystem contributions. Dorsey believes that Bitcoin’s continued growth depends on a collaborative, decentralized ecosystem.

Speculation About Identity and Influence

Some analysts and commentators have speculated about Dorsey’s deeper connection to Bitcoin’s origins, even proposing him as a potential candidate for Bitcoin creator Satoshi Nakamoto. These theories largely rest on coincidence and symbolic patterns rather than factual proof, and Dorsey himself has denied being Satoshi.

This speculation reflects both Dorsey’s visibility in the space and the fascination around Bitcoin’s origins, but it remains unsubstantiated.

Broader Impact on Crypto Markets and Policy

Dorsey’s advocacy has helped shape broader conversations about crypto policy, particularly in the United States, where regulatory frameworks lag behind innovation. By leveraging Block’s public profile and its integration of Bitcoin into mainstream financial tooling, he has influenced how regulators and financial institutions view digital assets.

His efforts have also shown that major incumbents can adopt Bitcoin and crypto technologies without sacrificing compliance or market trust. This narrative has helped open the door to institutional participation and mainstream investment in digital assets.

Legacy and Ongoing Vision

Jack Dorsey’s long-term commitment to Bitcoin sets him apart from many other tech founders who engage only tangentially with crypto. His focus on real-world utility, decentralized infrastructure, and widespread adoption has positioned Bitcoin as an integrated financial tool used by millions of consumers and businesses worldwide.

Through Block, Cash App, and open Bitcoin initiatives, Dorsey continues to push toward a future where Bitcoin functions as everyday money.
