**[Libra Designer: Stripe's Tempo Blockchain Is Doomed to Fail]** Odaily Planet Daily reports that U.S. fintech giant Stripe is promoting its new blockchain, Tempo, as a revolution in the global payments sector. However, Christian Catalini, one of the designers of Meta's failed stablecoin project Libra, stated that the Tempo blockchain is "doomed to fail." He believes that the problem with ventures like Tempo lies not in the code but in the incentive mechanisms. Once they achieve a monopoly in the market, the temptation to distort the competitive environment becomes irresistible. If Stripe and other fintech companies succeed in building walled garden blockchains, the result will not be financial innovation but a reshuffling of corporate monopolies. Open, permissionless networks are the only way forward; any other approach is destined to fail. (DL News)
