Block, Inc., the financial technology enterprise formerly known as Square, is not exclusively a Bitcoin company, but digital currency and blockchain technology represent a core and highly visible component of its business model. The company operates multiple major segments, including its merchant-focused Seller ecosystem and its consumer-facing Cash App platform, which facilitates peer-to-peer money transfers, banking services, and stock investing alongside digital asset transactions. Within Cash App, users can buy, sell, and transfer Bitcoin, and Block generates significant revenue volume from these cryptocurrency exchanges. Additionally, the company has pursued decentralized technology initiatives, hardware wallets, and open-source bitcoin mining systems through specialized business units like TBD and Spiral. While fintech and merchant services form the foundation of its operations, its deep integration of Bitcoin makes it a major corporate stakeholder in the cryptocurrency ecosystem.
