TL;DR
Square enables automatic bitcoin payment acceptance for millions of US small businesses.
Instant dollar conversion shields merchants from bitcoin price volatility and custody risks.
David Marcus compares Square’s bitcoin rollout to the internet’s TCP/IP foundational protocol.
Square begins integrating bitcoin into the payment infrastructure of millions of small U.S. businesses. Jack Dorsey announced that his company automatically enables bitcoin payment acceptance for eligible merchants, requiring no additional configuration whatsoever.
The system converts transactions to U.S. dollars instantaneously at point of sale, with near-immediate settlement and zero processing fees through 2026. The initiative marks one of the most aggressive efforts so far to integrate cryptocurrencies into conventional commerce, moving away from the model requiring manual feature activation.
What distinguishes this approach? Square eliminates the frictions that historically kept small businesses away from bitcoin. Merchants accepting bitcoin payments receive U.S. dollars by default. No exposure to price volatility. No need to manage custody. No accounting changes.
No technical friction. Miles Suter, head of bitcoin product at Block, wrote on X that “we’re making it easier for millions of businesses to accept bitcoin. This is how bitcoin as everyday money begins.” Jack Dorsey confirmed the rollout with a succinct comment: “today.”
The movement builds upon the broader “Square Bitcoin” initiative the company announced recently. But it signals a fundamental shift: bitcoin acceptance now integrates directly into existing payment systems, rather than requiring merchants to activate separate features. The millions of small businesses using Square for payments, inventory, and payroll access bitcoin acceptance automatically, without active decision, without technical evaluation, without workflow disruption.
Dorsey is known as a Bitcoin maximalist
He repeatedly expressed his aversion to stablecoins, those tokens backed by dollars that other sector players push. PayPal recently launched its own dollar-backed stablecoin, PYUSD, to tens of thousands of users across seventy global markets, as part of its strategy to deepen digital payments. Square takes a different path. Dorsey rejects stablecoin logic, but his company announces it will support dollar-pegged tokens due to growing customer demand. Pragmatism beats ideological purity when revenue depends on flexibility.
The rollout reaches millions of eligible merchants across the United States. Square does not target crypto-native users, but small businesses that historically reject cryptocurrencies due to complexity, risk, and friction. The company integrates Bitcoin payment tools directly into systems millions of merchants already use. Activation happens automatically. The merchant receives fiat currency. Customers pay in Bitcoin. The system handles conversion in the background, outside user view.
When Bitcoin Stops Being Technology and Becomes Infrastructure
That approach captured attention from industry leaders. David Marcus, CEO of Lightspark and former PayPal President, described the rollout as a potential “TCP/IP moment” for money. Marcus compares the move to early standardization of internet protocols, arguing that bitcoin could become a foundational layer for transferring value between systems.
“Enabling Bitcoin payments at scale could mirror how TCP/IP became the foundational protocol of the internet,” Marcus wrote. Transmission Control Protocol/Internet Protocol, TCP/IP, is the underlying scaffolding that allows data to move between networks. It enables disparate computers to communicate through a shared standard. No network controls TCP/IP. No single actor monopolizes the protocol. TCP/IP emerged as neutral infrastructure because it solved a specific problem: allowing incompatible systems to speak with each other.
Marcus suggests Bitcoin could play a similar role in financial infrastructure. By creating a common framework for moving value between users and platforms, bitcoin would create a sort of lingua franca for money transfer. Banks, payment platforms, e-commerce merchants, remittance systems: all would operate on shared infrastructure that none controls exclusively.
The TCP/IP analogy is particularly sharp because TCP/IP was never characterized as “revolution” during its early years. It was simply a technical standard solving an interoperability problem. Enterprises adopted it not because it was ideologically pure, but because it worked. The internet as we know it today exists because TCP/IP abstracted technical complexity behind application layers that end users never see. Users browse in web browsers. Browsers use HTTP. HTTP runs on TCP/IP. Users ignore TCP/IP completely.
Square attempts to abstract Bitcoin complexity similarly
Merchants accept payments. The system converts to dollars. End users see transactions in dollars or bitcoin according to preference. Nobody worries about custody, volatility, or private keys. Infrastructure handles complexity in the background.
Is that future possible? Miles Suter, on X, wrote that “bitcoin as everyday money is a long term journey for Block and the world. Many moves to make and many pieces to get in place for this to all come together the right way, and sustainably.” The phrase sounds cautious. Suter acknowledges that scale integration requires multiple actors, multiple platforms, multiple jurisdictions, multiple regulators, multiple years.
But Square’s rollout begins building that infrastructure. Merchants accepting bitcoin grow. Transactions in bitcoin increase. The real payment footprint of bitcoin expands. Regulators observe how cryptographic money functions in the context of ordinary commerce. Banks begin understanding the implications of neutral infrastructure for value transfer.
The contrast with PayPal is instructive
PayPal launched PYUSD to deepen control over digital payments. PayPal retains custody. PayPal controls issuance. PayPal monopolizes PYUSD infrastructure. Square takes the opposite path: it uses bitcoin, infrastructure controlled by no one, a protocol requiring no permission from PayPal or any other company.
That contrast reflects two visions for the future of digital money. PayPal imagines digital money controlled by large corporations, private infrastructure with high barriers to entry. Square imagines digital money on open infrastructure where any actor participates without permission. Both visions compete. Both seek adoption. The outcome will determine payment architecture for the next decades.
For small merchants, the difference is tangible. With PYUSD, they depend on PayPal: if PayPal decides to change fees, if it decides to block certain transaction types, if it decides to exit the market, the merchant loses access. With bitcoin on Square, the merchant uses infrastructure that exists independently of Square. If Square disappears tomorrow, bitcoin keeps functioning. That is structural security that company-controlled stablecoins can never offer.
Square’s rollout also reveals a shift in Jack Dorsey’s strategic calculation. Years ago, Dorsey was a purist: he rejected stablecoins, rejected halfway solutions, rejected anything that was not pure bitcoin. Today he announces Square will support dollar-pegged tokens because customer demand requires it. That is business pragmatism. That is recognition that everyday money requires value stability, and stablecoins provide stability in ways bitcoin has not yet fully achieved in small business context.
But bitcoin remains the foundation. The dollars Square settles to merchants come from converting bitcoin at point of sale. If bitcoin becomes the standard currency for settlement between platforms, if bitcoin becomes the infrastructure layer for value transfer, then Square is built upon a layer that no one controls. That is a stronger strategic position than any stablecoin.
The rollout begins in 2024. Transactions flow in 2024. Data from 2024 will show how many merchants use the feature, how much volume transits, what the behavioral patterns are. David Marcus expects the data to reveal a “TCP/IP moment.” The industry expects Square to have found the formula for bitcoin as everyday money without requiring users to understand cryptographic complexity. Regulators watch as open payment infrastructure functions at scale.
If Square succeeds in expanding bitcoin to millions of merchants without technical friction, without regulatory friction, without volatility friction, then bitcoin moves from being a speculative asset to being ordinary payment infrastructure. That would be the “TCP/IP moment” David Marcus describes. Not because bitcoin became perfect, but because it became invisible: so integrated into the ordinary flow of money that nobody thinks about it.
