Christian Catalini, co-creator of Facebook’s Libra mission, warned on Friday that Stripe’s Tempo and Circle’s Arc may succeed commercially however at the price of crypto’s decentralization perfect.
Launched in 2019, Libra was Meta’s daring bid to create a worldwide digital foreign money backed by a basket of steady belongings. The mission promised to make funds as seamless as messaging, however it triggered rapid backlash from regulators involved about monetary sovereignty, systemic danger, and person privateness. By 2022, Libra — renamed Diem in a bid to reset its picture — was shuttered and its belongings bought off.
Catalini, who served as Libra’s chief economist, used his Sept. 5 thread on X to revisit the mission’s early compromises and clarify why they matter now. He mentioned the unique open design, developed with Harvard economist Scott Kominers, was decreased to a brief appendix after months of regulatory negotiations.
The first main retreat, he wrote, was abandoning non-custodial wallets. Regulators insisted on a “clear perimeter,” which means a accountable middleman they may contact — and penalize — if issues arose.
For supervisors used to intermediated finance, a world the place customers actually held their very own cash was unmanageable. “For them, killing self-custody wasn’t a choice, it was an obvious necessity,” he recalled.
Catalini famous the irony: at the moment, open networks are growing compliance instruments native to blockchain that would have addressed these issues extra successfully than conventional frameworks. But again then, Libra was compelled to strip away decentralization, a change he described as an early sign of the place corporate-led tasks had been heading.
His broader lesson was stark: “As long as there is a single throat to choke — or a committee of them — you can’t truly rewire the system. Worse, any network with an architect is living on borrowed time.”
Arc and Tempo in the Spotlight
Catalini positioned Stripe’s Tempo and Circle’s Arc in that context. Both are new blockchains designed explicitly for funds, promoted as stablecoin-first infrastructure for enterprises and fintechs.
Circle launched Arc on Aug. 12, presenting it as a Layer-1 community purpose-built for stablecoin finance. Unlike public chains that depend on risky fuel tokens, Arc makes use of USDC for charges, providing predictable, dollar-denominated prices.
It integrates a built-in international change engine, guarantees sub-second finality, and consists of opt-in privateness options. Circle mentioned Arc will help cross-border funds, onchain credit score techniques, tokenized capital markets and programmable, automated funds.
Just weeks later, Stripe and Paradigm unveiled Tempo on Sept. 4, describing it as a payments-first blockchain able to dealing with over 100,000 transactions per second.
The community is EVM-compatible, contains a devoted funds lane with help for memos and entry lists, and permits customers to pay each transactions and fuel in any stablecoin. Stripe mentioned early design companions embrace Visa, Deutsche Bank, Revolut, Nubank, Shopify, OpenAI, Anthropic and DoorDash.
Both tasks had been marketed as steps towards mainstreaming stablecoin funds. But for Catalini, they raised a deeper concern.
A Revolution or a Failed Coup?
Catalini argued that corporate-led chains like Arc and Tempo danger merely rebuilding the outdated monetary system with new gamers in cost. Instead of displacing card networks and banks, he warned, they may elevate fintech giants to the similar place of dominance. “The throne will have new occupants, but it will be the same throne,” he wrote.
He additionally predicted such networks would fracture geopolitically, with Western and Eastern blocs unlikely to share a single corporate-led infrastructure. The consequence, he mentioned, could be competing monetary empires slightly than the borderless system crypto’s early advocates envisioned.
Ultimately, Catalini described Stripe’s Tempo as a “referendum on the ghost of Libra.” If it thrives, he urged, it could show Libra failed due to timing, not design — and present that the dream of open, permissionless cash has been overtaken by extra pragmatic, centralized options.
