Firstly, welcome to all the new subscribers. Whether you joined following the since viral LinkedIn post from Google’s Rich Widman that referenced my writing, or you want to follow along my entrepreneurial journey after my announcement that I was leaving Paxos, I’m glad you’re here.
This past weekend was a wild one if you were anywhere near crypto Twitter or the stablecoin world. We had Stripe and Paradigm announcing Tempo, and Hyperliquid dropping their RFP. For those of us who live and breathe this stuff, it felt like the whole feed was taken over. Excitement, hot takes, and a fair bit of chaos.
Today I want to focus on Tempo. It was highly anticipated, and when the details dropped, you could see the positioning right away: not “Stripe’s chain,” but pitched as a credibly neutral, payments-first L1 with a stacked list of design partners. That framing immediately drew comparisons to Libra. And then, as always, the carnage began: threads, explainers, skeptical takes, and plenty of noise.
After sitting with all of it and working through the arguments, I think the reaction really boils down to two debates:
Can a sponsor-led chain ever become credibly neutral, especially if it starts permissioned?
Did Stripe and Paradigm really need to build an L1 to achieve their goals, or could they have done it on an L2?
After digesting it all, here’s where I landed.
First: What is Tempo?
Tempo is a new payments-first L1 incubated by Stripe and Paradigm. The pitch is clear: not a “Stripe chain,” but neutral infrastructure purpose-built for stablecoin payments.
Some of the key design choices:
Performance: sub-second finality, 100k+ TPS.
Predictable, low fees: no volatile gas markets.
Stablecoin gas: pay fees in any stablecoin via an enshrined AMM.
Payment-specific UX: dedicated lanes, memos, batch transfers, opt-in privacy
AI in mind: support for microtransactions and “agentic” payments, with Anthropic and OpenAI as design partners.
They’ve also lined up an impressive set of design partners: Visa, Deutsche Bank, Nubank, Revolut, Shopify, DoorDash, Standard Chartered, Coupang, Mercury, and more.
The permissionless roadmap: start with a permissioned validator set, then decentralize over time to a fully permissionless network. The goal is credible neutrality.
From Stripe and Paradigm’s perspective, existing chains didn’t offer this combination of performance, features, and neutrality. So they decided to build their own. But that choice immediately raises the hardest question of all: can a sponsor-led chain that starts permissioned ever become credibly neutral?
That’s where the debate really starts.
Can Tempo Really Be Neutral?
Tempo is framed as neutral infrastructure: any stablecoin, any issuer, any provider. But what does neutrality actually mean in practice?
At its core, neutrality means that competitors and even adversaries can build on the network, and you cannot shut it down or censor it even if you wanted to. It’s not just about having rules, or a governance model with votes. If there’s a powerful sponsor, soft power matters: others may assume they can be coerced, or that business or political alignment could influence decisions. The real test of neutrality is whether the base layer is resilient enough that nobody can influence transactions or block access, even under outside political or regulatory pressure.
That’s why Christian Catalini and others argue that any inkling of centralization is a liability (see his Forbes article). If there’s a “throat to choke,” regulators or courts will find it, and neutrality collapses. Starting permissioned raises this exact concern: once one entity decides who validates, you’ve already broken the neutrality guarantee and there’s an implicit trust assumption that they’ll become neutral over time.
From there, the reactions split into two camps.
Some people simply don’t believe the claims. To them, Stripe and Paradigm are building an empire, declaring war on everyone else’s stack. “Credible neutrality” is just marketing gloss.
Others are more charitable but still skeptical: even if Stripe genuinely wants neutrality, it’s much harder than they think. Neutrality isn’t just about validator sets. It’s about client diversity, global community, independent developers, and jurisdictional spread. Ethereum and Solana took a decade to get there.
Still, it’s not impossible that neutrality could emerge over time. Stripe’s bet seems to be that distribution comes first, and neutrality follows. If they can pull enough volume onchain quickly, enough networks can be built that pull in participants regardless of early skepticism. Neutrality then becomes less of a starting condition, and more of a byproduct of scale and intention.
The big questions are:
How do you credibly commit to neutrality when you start permissioned?
How do you structure incentives so competitors and even adversaries want to join?
And how do you build the kind of governance and shared ownership model that gets others comfortable over the long run?
History shows it can happen. In the 1960s, Bank of America launched BankAmericard as a proprietary system. It later spun out into a consortium, eventually becoming Visa, a neutral (for banks) network where competing banks could safely participate. SWIFT followed a similar path, expanding from a small closed messaging club into a global standard (though still not fully open). Even in crypto, many networks began with controlled validator sets, Ethereum, Cosmos, Polkadot, Solana, and decentralized over time.
The difference now is distribution and timing. Stripe already controls massive merchant flows, and we’re at a moment where regulators and institutions are leaning into stablecoins. That combination could accelerate the journey, compressing what took others a decade into just a few years. The question is whether neutrality really can be speed-run, or whether Stripe’s involvement and the industry reaction is a structural impediment that prevents them from reaching the neutrality they aim for.
Why Build an L1?
The second big debate was whether Stripe and Paradigm really needed to launch a new L1. Couldn’t they have just built Tempo as an Ethereum L2?
Tempo’s team has been clear about their reasoning. Payments need things like:
Sub-second finality and consistent throughput — Ethereum finality is ~15 minutes today.
Multiple validators, not a single sequencer — important for partners who want neutrality guarantees. Most (if not all) major L2s today currently rely on a centralized sequencer.
Native payment-first features — stablecoin gas, memos, custom lanes, compliance hooks.
Fewer dependencies — no waiting on Ethereum’s roadmap.
On paper, many of these things are technically possible on an L2. Ryan Berckmans laid out one vision for how Tempo could have done it: a validium rollup on the OP stack with bonded preconfirmations (giving 200ms guarantees), SDK layers for payments features, fractal scaling through multiple L2s and L3s, and interoperability with other high-performance rollups. That architecture may be viable, but it’s also complex and untested. No one has pulled it off at the scale Stripe is aiming for.
That’s the crux. An L1 is simply the more pragmatic technical path today: fewer moving parts, fewer dependencies. If you’re Stripe, with billions in flows and a real chance to onboard merchants into stablecoins, it makes sense to optimize for speed and control, even if it comes at the cost of trust and perception.
And the perception cost is real. Launching an alt-L1 makes it look like Stripe wants to own the stack, and to Ethereum advocates it reads as undermining the L2 roadmap just as that ecosystem was consolidating.
But the upside is undeniable. Paradigm is an investment firm after all. If the choice between L1 and L2 is even close, the added control and value capture of an L1 makes the decision obvious. Stripe can probably live with the skepticism penalty if the reward is a payments network that actually works at scale.
What Actually Matters
The technical arguments are important, but the real test for Tempo will be adoption. Stripe’s bet is that distribution solves the cold start problem. If they can point billions in merchant flows at Tempo, neutrality may stop being a prerequisite and instead emerge as a byproduct of scale and network effects.
From here, I see three possible outcomes:
Stalled adoption: Tempo struggles to gain adoption. Stripe can’t convince others to build on it, and network effects remain concentrated around Ethereum. The ecosystem’s antibodies against sponsor-led chains prove too strong, and Tempo ends up serving as a public data point on the challenges of sponsor-led chains. Eventually, Stripe pivots: Tempo becomes an Ethereum L2, repurposing their investment and innovation but tapping into ETH’s security and ecosystem. Ironically, the Tempo launch itself may have galvanized Ethereum to accelerate its finality roadmap, closing the very gap that drove much of the original L1 decision.
Stripe-adjacent fiefdom (fragmented market): Tempo becomes a large network, but not the neutral base layer of payments. It’s open in theory, but competitors don’t want to contribute, so they spin up their own stacks, maybe Ethereum-aligned L2s, maybe regional payment chains. The result looks like telecoms or consumer wallets: overlapping coverage, partial interoperability, and fragmented liquidity. Still a huge success for Stripe and Paradigm, but not the shared global standard.
Neutrality breakthrough Distribution and incentives pull in competitors, issuers, and adversaries. Governance decentralizes quickly, validator and client diversity grows, and Tempo starts to look like a neutral settlement layer for payments and other financial use cases. Neutrality isn’t the starting condition but it’s reached through the pull of scale and well designed incentives.
All three scenarios are plausible, and two of them, the Stripe fiefdom or neutrality breakthrough, would still count as big wins. Of those, I think the Stripe fiefdom is most likely, as it can be driven mostly by Stripe’s distribution and economic incentives.
For the neutrality break through, a key determinant is whether they can design incentives that make competitors want to participate, not just tolerate.
A few things I’ll be watching:
How quickly they move from permissioned to permissionless validators.
How they use a token, equity, or other incentives to align disparate parties, particularly competitors who will probably be last to join.
How they balance governance vs decision making speed early on
In the end incentives will decide the story.
Conclusion
Tempo is a live experiment in whether distribution and product focus can compress the timeline for neutrality. By choosing to build an L1, Stripe and Paradigm took the pragmatic path: fewer dependencies, faster execution, and full control over incentives. But that choice comes with a trust penalty. Neutrality is hard to earn, and starting permissioned makes it even harder.
What happens from here isn’t really about technical design. It’s about whether Tempo can build sufficient traction and network effects that competitors and adversaries are incentivized to join. If they do, neutrality could emerge as a byproduct. If they don’t, Tempo still succeeds as a Stripe-adjacent network, big, valuable, and maybe even threatening to incumbents, but not the neutral global standard. And if the antibodies win, Tempo could stall out entirely, serving as a cautionary tale for sponsor-led chains.
Either way, the launch is already important. It forces the ecosystem to reckon with what neutrality really means, and it may even push Ethereum and others to accelerate their roadmaps. That’s a good outcome for stablecoins no matter what.
For me, the open question is simple: can distribution speed-run neutrality, or is it the one thing you can’t shortcut?
My guess is that it will come down to how the incentives and governance are structured. Unless competing parties have a strong long term incentive to join, we’re just going to build a more open (but not fully neutral) version of what we have today.
Really enjoyed this breakdown, a very even handed and well reasoned perspective on Tempo. Especially liked the last question, can distribution speed-run neutrality, or is it something that doesn’t have shortcuts?
