Square, the digital payments arm of Block Inc. founded by Jack Dorsey, has launched a groundbreaking initiative: more than four million U.S. merchants will soon be able to accept Bitcoin payments directly through their existing Square point-of-sale (POS) systems. This move is widely regarded as a pivotal leap for mainstream Bitcoin adoption in the U.S. retail sector, leveraging the high-speed, low-fee infrastructure of the Lightning Network for seamless transactions. The rollout is already underway for selected businesses and is expected to reach all eligible U.S. merchants by 2026 (source [1]).
Instant Payments, Familiar Experience
Users can now pay for goods and services at participating merchants by simply scanning a dynamic QR code generated by the Square terminal. Merchants have full flexibility: they can either retain the received Bitcoin or opt for automatic conversion into U.S. dollars at the point of sale. The aim is to deliver a payment experience almost indistinguishable from a standard credit card transaction, but with the added benefits of lower fees and near-instant settlement (source [2]).
The Lightning Network: Speed, Savings, and Security
By integrating the Lightning Network, Square makes Bitcoin payments viable for the real world: transactions are processed in seconds with minimal fees, compared to considerably slower and more expensive on-chain settlements. This eliminates one of the most persistent barriers for crypto payments and positions Bitcoin as a practical alternative for everyday retail activity (source [3]).
Jack Dorsey's Vision and Block’s Ecosystem
For Jack Dorsey and Block Inc., this move is another step towards realizing the vision of Bitcoin as the “currency of the internet.” Square’s merchant base can now instantly tap into a new demographic of crypto-native consumers. Combined with products such as Bitkey and Bitcoin conversions, Block Inc. is building a tightly integrated crypto payment ecosystem tailored to merchants and customers alike (source [4]).
Business Impact: A New Era for Retail Payments
Early reactions among merchants have been positive, with numerous small businesses and even large chains reporting faster checkouts and reduced costs versus traditional cards. Automatic dollar conversion removes volatility risk, clearing a path for pragmatic crypto adoption. Experts see this as a decisive milestone that could encourage other payment service providers and fuel even wider Bitcoin acceptance across retail sectors (source [5]).
