Tempo, Libra, and the Illusion of Neutrality

Corporate chains will boom and still end up orbiting neutral, public money rails.

When Stripe announced Tempo, its new blockchain for payments, the pitch was smooth: a fast Layer-1, fees in dollars not tokens, batched transfers, and a validator set that would “move toward permissionless.” With partners like Visa, Deutsche Bank, Revolut, and Shopify, the story practically wrote itself: finally, a chain for merchants and money, not bro memes.

If it felt familiar, that’s because we’ve seen this movie before. Meta’s Libra launched in 2019 with the same promise: speed, neutrality, and global scale. David Marcus, who ran it, now argues Libra didn’t fail on engineering, it failed because Washington decided Facebook controlling a currency was a non-starter. When one company owns the rail, regulators judge the sponsor, not the system.

I told Libra’s CMO the same thing before the collapse: it would not work. Sometimes I think I should have said the same to Christian Catalini back then as a friendly warning before he lived through the scars. (Christian, if you’re reading this, consider this the retroactive version).

My view was shaped long before by two things: first in the early 2000’s being a payments pioneer in emerging markets and second in 2010, being orange-pilled by Bitcoin, while living and working across five continents. In Lagos, Buenos Aires, and Istanbul, you learn quickly that money runs on neutrality and trust. Slick code can’t override decades of local practice, compliance norms, and geopolitical reality. Libra was hubris in blockchain form.

Tempo risks a smarter, subtler version of the same mistake. Silicon Valley would do well to listen to those who live the realities its products are meant to solve.

Neutrality Debt

Tempo insists it will be “permissionless from day one,” while decentralizing validators “over time.” But if Stripe and a handful of corporates decide who validates, set fees, and approve upgrades, that’s not neutrality, it’s dependence.

This gap between the promise and the architecture is what I call neutrality debt. The longer a network stays permissioned, the harder it becomes to shed political capture and commercial incentives. Today, Christian Catalini questions whether any corporate player can deliver on neutrality promises: "Would a sane competitor bet its future on Stripe's promise not to eventually favor its own products?"

Why Decentralization and Neutrality Are Non-Negotiable

Neutrality isn’t a philosophy. It’s the reason decentralized systems work when centralized ones collapse.

In IT, resilience comes from distributed design. The internet itself was built so no single failure, no switch, no server, no choke point, could take it down. Decentralized blockchains apply the same principle to money. A network is neutral when no single company, government, or regulator can rewrite the rules or exclude a user.

That property is what makes open systems credible. You don’t need to trust Stripe, or Circle, or the Fed; you trust the protocol because no single actor controls it. That credibility is why Ethereum secures trillions in stablecoin flows and Bitcoin secures trillions in value without marketing budgets,corporate partnerships, and commercial agendas.

And neutrality isn’t just about censorship resistance. It’s about coordination. Banks never adopted each other’s closed ledgers because no one wanted to live under a competitor’s rules. But they will plug into Ethereum because no one owns it. Neutrality lowers the coordination cost to zero. Everyone can join without asking permission, which is exactly why liquidity concentrates there.

That’s the “why”: decentralized systems win not because they’re fashionable, but because they are the only architecture that scales trust globally.

Why Corporate Chains Still Win in the Short Term

None of this means Tempo will flop. Merchants don’t care about governance models; they care about fees, speed, and predictability. Treasurers want stability, not token volatility. Stripe is superb at solving those pain points. Even if Tempo captures just a sliver of global flows, it could quickly become one of the most used blockchains on earth.

But onboarding is not anchoring. Stablecoins on Ethereum settled over $27 trillion in 2024 alone, more than Mastercard and Visa combined. Liquidity of that scale has gravity. It doesn’t migrate into a silo, no matter how slick the UX.

Failed AI Test?

The next great shift in payments won’t be human at all. It will be AI agents paying other AI agents.

I saw the outlines of this years ago at GE. In 2017–2018, we tested agent-driven supply chains. The intelligence worked: agents could recommend contracts, balance inputs, and pick suppliers. But when it came time to settle a payment, the system broke. Legacy rails, ACH, wires, cards, were too slow, too conditional, too dependent on human sign-off.

Today, intelligence is no longer the bottleneck. Klarna’s AI assistant already does the work of 700 humans in customer service. Salesforce, Microsoft, and AWS are shipping enterprise-grade agents that can negotiate refunds, execute payouts, and call APIs. Within the next two years, agents won’t just suggest, they’ll transact.

And when they do, they will demand rails that are:

• Always on: no batch windows or bank holidays.

• Composable: workflows that can hedge FX, post collateral, and trigger insurance in one motion.

• Predictable: the same rules every time, no matter the hour or jurisdiction.

Corporate chains fail here. Validators tied to corporate policy can’t guarantee predictable execution. Siloed designs break composability. Agents will route around those limits, just as users already route around banks, straight to neutral networks like Ethereum, where liquidity and programmability are native.

For AI commerce, neutrality is an engineering requirement.

Undermining the Dollar?

The geopolitical story is just as stark. Stablecoins, most of them dollars, are already extending U.S. power. In Turkey, Nigeria, and Argentina, they act as lifelines, embedding the dollar in economies where U.S. banks are weak or absent. That’s why Washington has shifted from skepticism to supervision. The GENIUS Act, passed in 2025, sets a federal framework for licensed issuers. The message is clear: stablecoins aren’t going away, and the U.S. wants them safe and onshore.

Emerging markets have already voted with their wallets. Nigerians, Argentines, Turks, they don’t wait for corporate chains or government pilots. They reach for neutral rails where dollar liquidity is deepest and the rules don’t change overnight. That is why stablecoins on Ethereum and Tron thrive (together they command almost all of stablecoin volume), while projects like the eNaira barely register.

But corporate chains cut against that strategy:

• They fragment liquidity. If Stripe, Circle, and Google each run their own chain, dollar liquidity splinters into shallow ponds. Network effects weaken. Rival blocs, from China’s e-CNY to Europe’s tokenized euro, gain room to compete.

• They invite capture. Corporate validators are easy to pressure. Forced freezes may satisfy one regulator but signal to the world that “dollars on this chain” are not neutral. Trust erodes.

• They deter adoption abroad. Banks and PSPs plug into neutral infrastructure precisely because no competitor controls it. A Stripe-controlled rail looks less like an open dollar standard and more like a corporate gate. Foreign institutions won’t line up.

In short, corporate rails weaken the very thing policymakers are trying to defend: the dollar as the universal settlement layer of global trade. Neutral, public rails strengthen it. They combine dollar ubiquity with on-chain transparency, letting regulators supervise flows in real time while preserving global trust.

Banks Are Surrendering to Decentralization

Closed, bank-owned systems, JPMorgan’s Onyx, Citi’s experiments, R3’s Corda, already tried to square this circle. None scaled. No bank wants to subordinate itself to another bank’s ledger. Neutral public rails solve that coordination problem. Regulators like them too: shared ledgers give supervisors visibility into risks in real time, instead of waiting for quarterly disclosures.

That’s why the irony is so sharp. At the moment Stripe is building Tempo, banks are being dragged, reluctantly but inevitably, onto open rails. Not because they want to, but because they have no choice.

The Barbell World

The future will not be one chain to rule them all. It will be a barbell:

• Corporate chains like Tempo or Circle’s Arc, dominating merchant onboarding and compliance-heavy flows.

• Neutral networks like Ethereum, anchoring global liquidity, tokenized assets, DeFi, and the machine economy.

Both will matter. Both will grow. But they serve different masters. Corporates build toll roads. Ethereum remains the highway system.

The Rhyme with Libra

Years ago, I told Libra’s CMO the project would fail because it wasn’t open, amongst other things. That wasn’t arrogance; it was pattern recognition, shaped by early immersion of global networks, pioneering payments, geopolitics of five continents and of course Bitcoin. People, and nations, will not entrust their money to rails controlled by someone else’s boardroom.

Tempo is smarter than Libra, better timed, less arrogant. It will likely process immense volumes. But traffic isn’t trust. Volume isn’t neutrality. Without credible neutrality at the foundation, corporate chains will always be bridges to the future, never the foundation of it.

Tempo will thrive in payments UX, but don’t confuse traffic with trust. The anchor points of the future, AI commerce and dollar hegemony, require neutrality. That gravity belongs to decentralization and fragmentation and dare I say, Ethereum.
