Christian Catalini, co-creator of Facebook's Libra, criticizes Stripe's Tempo blockchain for compromising core crypto principles of decentralization, warning that it could lead to centralization and replicate the failures of Libra.

He warns that corporate-led blockchains like Tempo and Circle's Arc risk repeating Libra's centralization issues, which ultimately led to its shutdown due to regulatory challenges.

Catalini warns that if Tempo and similar corporate blockchains succeed, it would mean the crypto revolution has been replaced by a controlled, market-structured system dominated by fintech giants.

Circle's Arc is a Layer-1 blockchain built for stablecoin finance, supporting cross-border payments and programmable transactions, using USDC for fees.

Catalini argues that projects like Arc and Tempo, designed for payments and stablecoins, may reinforce traditional financial power structures rather than disrupt them.

He warns these corporate blockchains could cause geopolitical fragmentation and create competitive financial empires instead of fostering a borderless, permissionless financial system.

Catalini describes Tempo as a 'referendum on the ghost of Libra,' suggesting its success might show Libra failed due to timing rather than design, and that centralized solutions have overtaken the original vision of open, permissionless money.

He suggests Libra's failure was partly due to bad timing, but Tempo's potential success indicates a shift toward a pragmatic, centralized financial system dominated by Western and Eastern players.

Catalini cautions that if the core flaw of a system designed by a single architect is true, then Stripe's efforts are just a costly continuation of the same flawed narrative, not a new chapter.

He criticizes corporate blockchains like Tempo for incentivization problems, where initial promises of fairness are betrayed as companies seek to tilt the playing field after gaining market power.

He argues that success of Tempo would signify a shift away from decentralization, favoring centralized, corporate-controlled systems and potentially leading to competing empires in Western and Eastern markets.

Libra, launched in 2019, aimed to create a global digital currency but faced backlash over concerns about financial sovereignty, systemic risk, and privacy, leading to its rebranding and closure.
