Jack Dorsey is taking another big step towards mainstream adoption of Bitcoin. His company, Block, deploys Bitcoin payments to more than 4 million U.S. Square merchants. This gives businesses an easy way to accept cryptocurrencies through the Lightning Network.

The move was first announced in October 2025. This is one of the largest real-world integrations of Bitcoin payments to date. It’s also a landmark moment for Dorsey, who has long envisioned Bitcoin as the future of global finance.
Bitcoin payments begin in earnest across Square
Jack Dorsey’s Square Bitcoin payment feature was officially launched on October 8th. Full rollout begins November 10th. Sellers will be able to receive Bitcoin directly. Uses your existing Square point of sale (POS) system, so no new hardware is required. Customers can pay by scanning a QR code. Meanwhile, merchants can choose to keep their Bitcoins or instantly convert them to USD.
This flexibility gives businesses complete control over how their cryptocurrency transactions are processed. Especially those who are wary of market volatility. Block will also waive all processing fees for Bitcoin payments throughout 2026. This makes Bitcoin an attractive option for small and medium-sized businesses. The company said the decision is aimed at helping merchants secure more revenue. Additionally, explore new payment possibilities without any additional costs.
Empowering sellers through Bitcoin
Block’s head of Bitcoin product explained that the goal is simple: economic empowerment. By enabling Bitcoin transactions, Square merchants can reach a wider audience. This also includes crypto-savvy customers who prefer digital payments. The company highlighted data from its Bitcoin Conversion Study. This shows that 12% of Square sellers already set aside a portion of their sales for automatic Bitcoin conversion.
A further 29% are considering this feature for business savings. Meanwhile, 89% plan to use Bitcoin as a long-term investment asset. This deployment also builds on Jack Dorsey’s pre-block feature Bitcoin Conversions, which was launched in 2024. This tool allows merchants to automatically convert a portion of their card sales into Bitcoin. This will help you diversify your savings and protect against inflation.
Leverage the Lightning Network
All Bitcoin transactions on Square are performed through the Lightning Network. Specifically, it is a second layer protocol designed to make payments faster and cheaper. This is because transactions can be processed almost instantly and at a fraction of the cost of traditional payments. Additionally, with Lightning, merchants can avoid chargebacks and have instant access to their funds. Obviously, this is a huge improvement over standard payment systems.
Jack Dorsey has repeatedly referred to Bitcoin as “the money of the Internet.” Millions of Square merchants are currently planning to accept it. That vision is one step closer to reality. With this integration, Bitcoin could become more than just an investment asset. However, it is a mainstream payment option in everyday business.
