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 just accept bitcoin funds by way of 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 longer term as one the place the Bitcoin Blockchain would play a pivotal function. Sq. grew to become a subsidiary of Block Inc and now offers primarily with fee terminal expertise. At this time, Block has 8,584 BTC on its steadiness sheet valued at virtually 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 resembling Money App, Bitkey, Proto, Spiral, TBD and Tidal.

In an unique interview with Bitcoin Journal, Mile Suter, product lead at Block shared insights into their imaginative and prescient for the longer term and Bitcoin’s preferrred function in it, saying that, “We predict Bitcoin achieves its final future when it’s getting used as on a regular basis cash. Identical to Satoshi supposed. I believe that Bitcoin as a world monetary infrastructure that everybody can entry lets corporations like Block function in a way more world method. And I believe 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.”
Beneath you’ll discover quick overviews of a few of Block’s Bitcoin-related corporations, significantly these serving retail, with unique quotes from Suter on how they serve important roles within the path to hyperbitcoinization.
Sq.
Launched in 2009, Sq. is a point-of-sale (POS) system enabling retailers to just 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 just 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 alternate. “On the Sq. facet, we now have over 4 million retailers within the U.S. with a full suite of point-of-sale, stock, taxes, reporting, like one of the best within the enterprise by way of conventional funds processing. This initiative goes past simply Bitcoin funds,” mentioned Suter.
With the full-stack accounting integration of Bitcoin, retailers that needed to just accept the digital forex however couldn’t due to lack of tooling now have the door huge 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 immediately.
Corporations will quickly have all of the instruments to just accept bitcoin funds and put them instantly into their firm treasury quite 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, certainly, Block can also be shifting in that path for his or her shoppers. Suter added that “one factor I really 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 massive companies. I consider that holding Bitcoin in your steadiness sheet shouldn’t simply be a Wall Avenue luxurious.”
Money App
Money App, maybe probably 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 overall, by charging ~2% per commerce.
Money App may additionally be the primary mainstream funds app to combine Lightning, Bitcoin’s funds community. It’s on the slicing fringe of the trade, producing the very 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 wish to get too into the weeds right here, however I can confidently say that we now have probably the most gifted set of Lightning engineers on the earth 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 function 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’t simply simply purchase and ship bitcoin through Money App, but in addition automate purchases, an funding technique generally known as DCA or greenback value 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 folks 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 often not doable 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 probably not labored very effectively up till now, can lastly change into a actuality.
Bitkey
Anchored within the elementary worth proposition of Bitcoin — censorship resistance by way of particular person liberty and self custody — Block has launched a brand new {hardware} pockets product known as Bitkey. The system is designed particularly for Bitcoin safety, utilizing a preferred expertise known as multisignature, which decentralize the passwords — non-public keys— wanted to maneuver the bitcoin to a few totally different units: the Bitkey {hardware}, a key saved for restoration in Block’s servers and a 3rd key encrypted with the consumer’s credentials and saved on the consumer’s chosen Google drive account.
The Bitkey, launched globally in 2024, makes numerous design selections that depart from the best way different {hardware} wallets within the trade perform — probably the most main and controversial distinction being that it by no means reveals non-public key materials to the consumer. In contrast to each different {hardware} pockets and most self-custody Bitcoin and crypto apps, Bitkey hides key materials virtually solely from the consumer, as an alternative giving them numerous well-designed instruments to safe, get well and inherit their bitcoin securely to their family members. Suter famous that “we constructed Bitkey to develop who can safely self-custody. We — Bitcoiners — joke that you must 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 system appears to be like and looks like alien expertise, each unit with a singular blended 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 consumer expertise of the standard Bitcoin seed backup method. Whereas the design has been out there for barely a yr and no public information on gross sales numbers has been launched, it is going to be attention-grabbing to see if they will break new floor into {hardware} pockets adoption — a metric traditionally poor for an trade so culturally outlined by self custody.
