Introduction

You buy a few Philips Hue smart bulbs because they are said to be the best. Their app interface is sleek, the colors are vibrant, and when you dim the lights with your phone, you feel like a tech wizard, very high-end.

Then you decide your thermostat should be smart too. Nest has the most powerful AI, so you buy that. Different apps, different accounts, but that’s okay; it’s just another feature.

Before you know it, your life is in chaos. Your Ring doorbell can’t communicate with your Alexa speaker, the Alexa speaker can’t control your Apple HomeKit garage door, and the garage door can’t connect to the Samsung SmartThings hub. You need four different apps to turn on lights, adjust the temperature, and lock doors. Every company promises you a "seamless smart home experience," but somehow your house feels "heavier" than before, just with more apps.

Will Circle and Stripe repeat the same mistakes in the cryptocurrency space?

Circle and Stripe

In August 2025, two major announcements were made.

First, news broke that the $50 billion payment giant Stripe is collaborating with crypto venture firm Paradigm to develop a blockchain called Tempo that is "high-performance and payment-focused." A day later, Circle, the company behind the $67 billion USDC stablecoin, announced the Arc project, a Layer 1 blockchain designed specifically for stablecoin payments, foreign exchange trading, and capital markets.

Inside Circle Arc: Circle has built Arc specifically around its USDC stablecoin. Most blockchains require you to pay transaction fees with their native tokens. For example, Ethereum uses ETH, and Solana uses SOL. But on Arc, you can pay fees directly with USDC, without needing to hold volatile tokens to use the network.

Arc has a built-in foreign exchange engine. There’s no need to use external services or decentralized exchanges (DEX) to convert currencies; Arc handles foreign exchange transactions natively at the protocol level. Send USDC, and the recipient will receive EURC (Euro Coin), with the conversion process done automatically, without third-party services or additional fees.

There’s also privacy control. Most public blockchains (Ethereum, Bitcoin, Solana) expose all information: addresses, amounts, timestamps. Privacy coins like Monero hide everything by default. Arc offers selective privacy, allowing institutions to hide transaction amounts while keeping addresses visible, and it has built-in regulatory compliance features. It’s designed for businesses that need competitive privacy but not complete anonymity.

Inside Stripe Tempo: Stripe’s differentiation seems to lie in abstracting the user experience. Other crypto payment solutions still feel like using cryptocurrency—connecting wallets, signing transactions, waiting for confirmations—while Tempo seems designed to make blockchain payments feel indistinguishable from credit card payments from the user’s perspective.

Being Ethereum-compatible means it can leverage existing DeFi infrastructure and developer tools, but the advantage lies in integrating with Stripe’s existing merchant ecosystem. Millions of businesses using Stripe may be able to add crypto payment functionality without changing their checkout processes or learning new systems.

Most importantly, Stripe’s existing relationships with banks and regulators can solve a significant problem. Most crypto payment solutions struggle with the "last mile"—moving funds from the blockchain back to regular bank accounts. Stripe already has the banking partnerships that other crypto companies have spent years building.

Why I Still Feel Troubled

So, we return to my fragmented digital home, where the problems start multiplying, just like the notification badges on my various home automation apps.

What troubles me first is: where is the demand for these dedicated blockchains?

Circle and Stripe have been talking about stablecoin payments and enterprise features, but the real active area for stablecoins is in DeFi. People use USDC to buy other crypto assets, participate in lending protocols, trade on decentralized exchanges, and interact with a broader ecosystem of financial applications. All of this primarily happens on Ethereum.

It’s like building the world’s most advanced smart thermostat but only being able to use it in a house without any other smart devices.

Sure, this thermostat may be technically superior, but you’ve isolated yourself from the entire ecosystem where people actually want to use smart home features.

The second question: what’s the point of reinventing the wheel?

Everything Circle and Stripe are pursuing—faster transaction speeds, lower fees, customizable features, enterprise branding—can be achieved through Ethereum Layer 2 solutions. You can gain the security of Ethereum’s base layer, access the largest DeFi ecosystem, and customize your network on demand.

Some Layer 1 blockchains have already realized this. The mobile payment-focused independent blockchain Celo announced plans to transition to Ethereum Layer 2. They did the math and found that joining the Ethereum ecosystem made more sense than building their own network effects from scratch.

The more blockchains there are, the more bridges are needed. And bridges are the problem… they transfer assets between different blockchains. Essentially, you lock your tokens on one chain through complex smart contracts, then mint equivalent tokens on another chain. But bridges are often hacked. A lot. I swear by Ronin. We’re not talking about the minor inconvenience of switching from the Philips Hue app to the Nest app. We’re talking about potential financial loss if the bridge software fails.

The user experience is terrible. In my smart home, the worst-case scenario is having to open another app to turn off the porch light. But for enterprise blockchains, users may need to use different wallets, different gas tokens, different interfaces, and different security settings for each network. Most people struggle to manage one crypto wallet. Imagine explaining why they need to use different wallets for Stripe payments and Circle transfers.

But what truly confuses me is that the network effects simply don’t exist.

The value of a payment network grows exponentially with the number of users and applications. Ethereum has the most developers, the most applications, and the most liquidity. As of mid-2025, Ethereum's TVL (Total Value Locked) was $96 billion, accounting for about 60-65% of DeFi activity. Solana, as a high-performance alternative, had a TVL of $11 billion. Other major chains like Binance Smart Chain ($7.35 billion), Tron ($6.78 billion), and Arbitrum ($3.39 billion) share the remaining portion.

These enterprise chains are opting out of this network effect to build something isolated, hoping users will come automatically.

Would you build a perfect store on a deserted island? Sure, countries like the UAE have built cities like Dubai, and people did go there. But that was due to geographical constraints. They had to do it.

Finally, there’s a competitive issue that no one wants to face directly. Are these companies really trying to build better infrastructure, or are they just unwilling to share a "sandbox" with competitors? When I look at the chaos in my smart home, I find that each company has a reasonable technical justification for their choices. But the real driving force is often that they don’t want to rely on someone else’s platform or pay fees to competitors.

Maybe that’s the reality. Circle doesn’t want to pay Ethereum transaction fees, and Stripe doesn’t want to build on infrastructure they can’t control. That makes sense. But let’s be honest about what’s really going on. This isn’t about innovation or user experience; it’s about control and economic benefits.

The Real Kings Don’t Seem Worried

Ethereum doesn’t seem to care much about this. The network processes over a million transactions daily, capturing most of the DeFi activity, and has recently seen massive institutional inflows through its ETFs. On one day in August, net inflows into Ethereum ETFs reached $1 billion, surpassing the total for Bitcoin ETFs over the past week.

The Ethereum community's reaction to these enterprise chains is interesting. Some see it as an affirmation. After all, both Arc and Tempo are built as EVM-compatible chains, essentially adopting Ethereum’s development standards.

But there’s a subtle threat here. Every USDC transaction conducted on Arc instead of Ethereum is a fee income that doesn’t flow to Ethereum validators. Every merchant payment processed on Tempo instead of Ethereum Layer 2 is an activity that doesn’t contribute to Ethereum’s network effects.

Solana may feel this competition more acutely. The network positions itself as a high-performance alternative to Ethereum, particularly in payments and consumer applications. When large payment companies choose to build their own chains instead of adopting Solana, it undermines Solana’s long-held argument that "everything can run on a fast computer."

The Graveyard of Enterprise Blockchains

History has not been kind to companies that attempt to build their own blockchains. As I mentioned earlier, Celo made the same move in 2023.

Remember Facebook’s Libra? It started as an ambitious plan to create a global digital currency, then became Diem, and eventually became unsustainable under regulatory pressure, leading to its breakup and sale. Don’t forget that under today’s clearer rules, the GENIUS Act explicitly outlines how stablecoin issuers can operate, and Facebook’s project might actually succeed.

JPMorgan’s blockchain attempts may provide the most relevant cautionary tale. The bank spent years developing JPM Coin (digital dollar), Quorum (their private blockchain network), and other blockchain projects. Despite having almost unlimited resources, regulatory relationships, and a large existing customer base, these projects never gained meaningful adoption outside of JPMorgan’s own business. JPM Coin processed billions of dollars in transactions, but primarily just for fund transfers between institutional clients within the bank.

Even attempts by large payment companies have not been particularly inspiring. PayPal launched its own stablecoin (PYUSD) in 2023, becoming the first major U.S. fintech company to enter the stablecoin space. But PayPal chose to launch on existing networks like Ethereum rather than build custom infrastructure. The result? PYUSD’s market cap is only $1.102 billion, trivial compared to USDC’s $67 billion, and is primarily confined to PayPal’s own ecosystem.

This raises a question: if a company like PayPal, with extensive influence and payment expertise, can’t make a significant impact with just a stablecoin, why do Circle and Stripe think building an entire blockchain will perform better?

This model suggests that building a successful blockchain requires more than just technical capability and financial resources. You need network effects, developer enthusiasm, and organic adoption, which are extremely difficult to manufacture even with corporate backing.

Will this time be different?

We have reason to believe that Circle and Stripe may succeed where others struggle.

First, regulatory clarity has significantly improved. The GENIUS Act passed in the U.S. provides a clear framework for stablecoin issuers, eliminating much of the uncertainty faced by early enterprise blockchain efforts. When Circle launches Arc, they are no longer operating in a legal gray area. They are a publicly traded company operating under clear rules.

Second, these two companies already have what JPMorgan lacks: a large user base that is not primarily crypto-centric. Stripe processes over $1 trillion in transactions annually for millions of businesses worldwide and has been systematically building its crypto infrastructure—acquiring Bridge (stablecoin infrastructure) and Privy (crypto wallet technology) for $1.1 billion to create an end-to-end payment stack. Circle’s USDC is integrated into hundreds of applications and trading platforms. They are not building a blockchain and hoping someone will use it; they are building infrastructure for the users they already serve and providing tools for seamless access.

Matt Huang from Paradigm emphasized how Stripe’s strategy allows blockchain technology to "fade out" of the ordinary user’s view. Imagine online payments with instant settlement, lower fees, and programmable features, but the merchant integration looks exactly like the existing Stripe checkout process. This is completely different from asking people to download MetaMask and manage seed phrases. It’s a Web2 user experience combined with Web3 infrastructure. Users don’t even feel any "blockchain flavor."

Third, the technology itself has matured. When JPMorgan was experimenting with blockchain in 2017-2018, the infrastructure was indeed very primitive. Today, building a high-performance blockchain with institutional-level functionality is challenging but not unprecedented. Circle has acquired the Malachite consensus engine team, providing them with battle-tested sub-second finality technology. Stripe’s collaboration with Paradigm brings deep crypto expertise to complement its payment knowledge.

Cost dynamics have also changed dramatically. In 2017, launching a new blockchain typically required $1 million to $5 million, with development cycles of 1-2 years or longer. By 2025, the average cost of launching a functional blockchain application is $40,000 to $200,000, typically taking 3-6 months, thanks to improved developer tools, consensus engines, and blockchain-as-a-service platforms. Modern deployments can be up to 43% cheaper in certain areas than centralized applications, due to efficiency gains and infrastructure scaling. Payment companies realize they are paying others for infrastructure they could build themselves. Instead of paying Circle fees for USDC transactions or relying on Ethereum’s fee structure, companies like Stripe can now build their own infrastructure stack at a fraction of the cost they would pay to third parties.

This is a classic "build or buy" decision, where the cost of building has dropped from millions to hundreds of thousands.

Coexistence Issues

So, where does this lead us? Are we heading towards a fragmented future where every large company runs its own blockchain, or will market forces drive integration and interoperability?

Early signs suggest that the future is more likely to be pragmatic coexistence rather than winner-takes-all competition. Circle has made it clear that Arc will complement rather than replace its multi-chain strategy. USDC will continue to operate on Ethereum, Solana, and dozens of other networks. Arc is positioned as an additional option for users needing specific features like institutional privacy, guaranteed settlement times, or built-in foreign exchange functionality.

Stripe’s strategy seems similar. Tempo is not designed to completely replace existing payment channels but to provide alternatives for use cases where blockchain functionality has clear advantages. Cross-border payments, programmable money, and merchant settlements are areas where blockchain technology truly excels over traditional systems.

User experience will ultimately determine whether this fragmentation becomes a feature or a problem. If "chain abstraction" technology develops as promised, users may unknowingly use different blockchains. Your payment app might automatically route transactions through the network with the best speed and cost.

My guess (if I’m a bit optimistic) is that we will see both outcomes simultaneously, but in different market segments.

For institutional and enterprise users, multiple dedicated blockchains may thrive. A multinational company transferring $100 million between subsidiaries cares about compliance features, settlement guarantees, and integration with existing financial systems. They don’t care about gas price fluctuations, whether their blockchain has the coolest NFT projects, or the most active DeFi protocols. A chain that allows enterprises to connect directly to traditional banking systems, provides built-in regulatory reporting, or guarantees settlement times will be more appealing than Ethereum’s general-purpose infrastructure.

Arc may indeed serve these users better than Ethereum.

Stable fees, instant settlement, and built-in compliance features may be more important to CFOs than accessing the latest DeFi protocols.

For retail users and developers, network effects remain crucial. The blockchain with the most applications, the most liquidity, and the most developer activity will continue to attract more of the same. Today, that is still Ethereum, and these enterprise chains do not seem to directly challenge that dominance.

One variable is whether these enterprise blockchains will remain enterprise-focused. If Stripe offers merchants faster and cheaper payment options, and customers are unaware they are using a blockchain, it could transcend the realm of enterprise applications.

But the key to infrastructure is that the best kind is invisible. When you flip the light switch, you don’t think about the power plant or the transmission lines. When these blockchain experiments succeed, it will be because they make the underlying technology completely disappear.

Whether this will actually happen remains to be seen. For now, we are in a land grab phase, with everyone wanting a piece of the future financial infrastructure.

That’s it for today’s deep dive. See you tomorrow.
