Christian Catalini, a key figure in the now-defunct Facebook Libra cryptocurrency initiative, recently expressed concerns about the potential drawbacks of Stripe’s Tempo and Circle’s Arc. He suggests that while these platforms might find commercial success, they could inadvertently undermine the core principle of decentralization that underpins the crypto world.
Libra, envisioned as a global digital currency backed by a diverse range of assets, was launched in 2019 by Meta. Its ambitious goal was to streamline payments to the simplicity of sending a message. However, the project faced immediate regulatory resistance due to worries about financial stability, national sovereignty, and user data protection. Ultimately, Libra was rebranded as Diem in an attempt to improve its public image but was eventually discontinued in 2022, with its assets being liquidated.
Catalini, who held the position of chief economist for Libra, took to X (formerly Twitter) on September 5th to reflect on the early compromises made during the project’s development and their current relevance. In his thread on X, he explained that the original, more open design, conceived in collaboration with Harvard economist Scott Kominers, was significantly curtailed after months of negotiations with regulators.
According to Catalini, one of the most significant concessions was abandoning the concept of non-custodial wallets. Regulators insisted on having a “clear perimeter,” which meant requiring a responsible intermediary they could contact – and hold accountable – if any issues arose.
He elaborated that for regulators accustomed to traditional, intermediary-based finance, the idea of users having complete control over their funds was deemed unworkable. “For them, eliminating self-custody wasn’t a choice, it was a fundamental necessity,” he stated.
Catalini highlighted the irony that blockchain technology now offers compliance tools that could have addressed the regulators’ concerns more effectively than conventional methods. However, at the time, Libra was compelled to sacrifice decentralization, a move he sees as an early indicator of the direction corporate-led projects were heading.
His main takeaway is a cautionary one: “As long as there is a single point of control – or a small group in charge – you can’t truly revolutionize the system. Moreover, any network designed by a central authority is inherently limited.”
The Focus on Arc and Tempo
Catalini used this context to examine Stripe’s Tempo and Circle’s Arc. Both are new blockchain platforms specifically designed for payment processing, marketed as stablecoin-centric infrastructures for businesses and fintech companies.
Circle introduced Arc on August 12th, positioning it as a Layer-1 blockchain network tailored for stablecoin finance. Unlike conventional public blockchains that rely on volatile gas tokens, Arc utilizes USDC for transaction fees, providing predictable, dollar-denominated pricing.
Arc includes an integrated foreign exchange engine, boasts near-instant transaction finality, and incorporates optional privacy features. Circle states that Arc will facilitate cross-border payments, on-chain credit systems, tokenized capital markets, and automated payment solutions.
Shortly after, on September 4th, Stripe and Paradigm announced Tempo, describing it as a blockchain designed with payments as its primary focus, capable of processing over 100,000 transactions per second.
Tempo is EVM-compatible and features a dedicated payment channel supporting memos and access lists, allowing users to pay transaction fees and gas fees using any stablecoin. Stripe’s initial design partners include major players such as Visa, Deutsche Bank, Revolut, Nubank, Shopify, OpenAI, Anthropic, and DoorDash.
Both Arc and Tempo are being promoted as advancements toward the widespread adoption of stablecoin payments. However, Catalini believes they raise a more fundamental question.
Evolution or More of the Same?
Catalini contends that corporate-led blockchains like Arc and Tempo run the risk of simply recreating the existing financial system with different entities in control. He warns that instead of disrupting established card networks and banks, they could simply elevate fintech giants to similar positions of power. “The leaders may change, but the underlying structure remains the same,” he stated.
He also anticipates that such networks will become fragmented along geopolitical lines, with Western and Eastern blocs unlikely to share a single, corporate-controlled infrastructure. This, he argues, could lead to competing financial systems instead of the borderless financial landscape envisioned by early crypto advocates.
In conclusion, Catalini sees Stripe’s Tempo as a “referendum on the legacy of Libra.” He suggests that if Tempo succeeds, it might indicate that Libra’s failure was due to poor timing, rather than a flawed design, and that the ideal of open, decentralized finance has been superseded by more practical, centralized solutions.
