Its corporations span funds apps and service provider tooling with Bitcoin integration, the event of bitcoin mining {hardware}, open supply software program growth, a decentralized finance protocol for peer-to-peer markets and even a self-custody {hardware} pockets.
Previously known as Sq. and based in 2009, the corporate began integrating Bitcoin into its expertise providing as early as 2014 through Money App — its most well-known subsidiary — permitting retailers to simply accept bitcoin funds by the app. In 2021, Sq. Inc formally rebranded to Block Inc, doubling down on its dedication to Bitcoin and affirming its imaginative and prescient of the long run as one the place the Bitcoin Blockchain would play a pivotal position. Sq. turned a subsidiary of Block Inc and now offers primarily with fee terminal expertise. Right this moment, Block has 8,584 BTC on its stability sheet valued at nearly 1 billion {dollars}, with a mean buy value of 30,405 {dollars} per bitcoin.
Of Block’s subsidiaries and investments, most have express connections to Bitcoin or blockchain methods equivalent to Money App, Bitkey, Proto, Spiral, TBD and Tidal.

In an unique interview with Bitcoin Journal, Mile Suter, product lead at Block, shared insights into the corporate’s imaginative and prescient for the long run and Bitcoin’s perfect position in it. He mentioned that, “We predict Bitcoin achieves its final future when it’s getting used as on a regular basis cash. Similar to Satoshi supposed. I feel that Bitcoin as a worldwide monetary infrastructure that everybody can entry lets corporations like Block function in a way more international method. And I feel that funds are important to sustaining the core properties that make Bitcoin distinctive and in the end will make it win in the long term.”
Under you’ll discover quick overviews of a few of Block’s Bitcoin-related corporations, notably these serving retail, with unique quotes from Suter on how they serve essential roles within the path to hyperbitcoinization.
Sq.
Launched in 2009, Sq. is a point-of-sale (POS) system enabling retailers to simply accept card funds and handle operations like stock, payroll and enterprise loans. Serving 4 million sellers and processing $241 billion yearly as of 2024, Sq. introduced that it started rolling out Bitcoin funds for retailers on the Bitcoin Vegas convention in 2025, permitting them to simply accept bitcoin seamlessly through its POS {hardware}.

The transfer marks a serious milestone in Bitcoin’s integration with retail fee methods, establishing a lacking pillar up till now within the enterprise toolkit wanted to essentially use bitcoin as a medium of trade. “On the Sq. facet, now we have over 4 million retailers within the U.S. with a full suite of point-of-sale, stock, taxes, reporting, like the most effective within the enterprise when it comes to conventional funds processing. This initiative goes past simply Bitcoin funds,” mentioned Suter.
With the full-stack accounting integration of Bitcoin, retailers who wished to simply accept the digital foreign money however couldn’t due to a scarcity of tooling now have the door vast open. However the imaginative and prescient is larger than that. “And we’re going to offer a full-stack Bitcoin banking suite particularly designed for small companies,” Suter added, leaning into the rising pattern of bitcoin treasury corporations and methods that’s dominating Bitcoin information at present.
Firms will quickly have all of the instruments to simply accept bitcoin funds and put them straight into their firm treasury moderately than immediately promote bitcoin for {dollars}. In the event that they want liquidity, they’re already capable of put that bitcoin as collateral and get dollar-denominated loans straight to their checking account through corporations like Unchained — although, for sure, Block can be shifting in that path for his or her purchasers. Suter added that “one factor I like about this full-stack Bitcoin banking suite is that we’re democratizing entry to Bitcoin treasury instruments that had been beforehand solely accessible to giant firms. I consider that holding Bitcoin in your stability sheet shouldn’t simply be a Wall Avenue luxurious.”
Money App
Money App, maybe essentially the most famend model throughout the Block portfolio, completes the retail funds facet of the hyperbitcoinization engine Block is constructing. Launched in 2013, Money App is a consumer-focused digital pockets with a reported 57 million lively customers in 2024, providing person-to-person funds, debit playing cards, shares and Bitcoin buying and selling, and tax submitting. Money App reported $10 billion in bitcoin-sourced income in 2024, making up 62% the entire, by charging ~2% per commerce.
Money App may also be the primary mainstream funds app to combine Lightning, Bitcoin’s funds community. It’s on the slicing fringe of the business, producing the best publicly disclosed, bitcoin-denominated income however working the Lightning Community at 9.7% return. This isn’t some bizarre crypto magic yield, and may solely be achieved by ensuring bitcoin funds are extremely environment friendly and dependable. Suited famous that “to me, it’s proof that Bitcoin is already a functioning fee community, not digital gold. It’s greater than that. And I don’t need to get too into the weeds right here, however I can confidently say that now we have essentially the most proficient set of Lightning engineers on this planet engaged on these issues.”
Exalted in regards to the success of Money App’s Bitcoin integration, Suter added that “we’re tremendous enthusiastic about Lightning’s position in making Bitcoin on a regular basis cash as a result of that’s actually, from a Block Inc. perspective, we consider that’s important for Bitcoin’s future, Satoshi’s authentic imaginative and prescient, peer-to-peer digital money.”
Shoppers can not simply simply purchase and ship bitcoin through Money App, but additionally automate purchases, an funding technique often called DCA or greenback price averaging, which has been mathematically demonstrated to be among the finest funding methods there are in bitcoin.

The mix of Money App and Sq. unlocks what tech individuals name a “fly wheel,” a time period used to explain self-reinforcing loops of shopper and enterprise habits that may drive a enterprise to new heights and which is normally not attainable if a constructing block in that enterprise logic is lacking. Maybe with these two main integrations, the imaginative and prescient of Bitcoin funds dreamt about by early adopters for over a decade, which have not likely labored very effectively up till now, can lastly turn into a actuality.
Bitkey
Anchored within the elementary worth proposition of Bitcoin — censorship resistance by particular person liberty and self custody — Block has launched a brand new {hardware} pockets product known as Bitkey. The gadget is designed particularly for Bitcoin safety, utilizing a preferred expertise known as multisignature, which decentralize the passwords — personal keys— wanted to maneuver the bitcoin to 3 completely different gadgets: the Bitkey {hardware}, a key saved for restoration in Block’s servers and a 3rd key encrypted with the person’s credentials and saved on the person’s chosen Google drive account.

The Bitkey, launched globally in 2024, makes numerous design selections that depart from the way in which different {hardware} wallets within the business perform — essentially the most major and controversial distinction being that it by no means exhibits personal key materials to the person. Not like each different {hardware} pockets and most self-custody Bitcoin and crypto apps, Bitkey hides key materials nearly solely from the person, as an alternative giving them numerous well-designed instruments to safe, get better and inherit their bitcoin securely to their family members. Suter famous that “we constructed Bitkey to broaden who can safely self-custody. We — Bitcoiners — joke that it is best to onboard your grandma to self-custody, however I hear numerous tales of that being true and other people reaching out as a result of the onboarding was so seamless.”
The gadget seems to be and appears like alien expertise, each unit with a novel combined stone sample, and that lights as much as the contact, like it’s alive. It’s a profound rethinking of self custody, born of a deep critique of the person expertise of the standard Bitcoin seed backup method. Whereas the design has been available in the market for barely a yr and no public knowledge on gross sales numbers has been launched, it will likely be fascinating to see if they’ll break new floor into {hardware} pockets adoption — a metric traditionally poor for an business so culturally outlined by self custody.
