Libra

Diem (formerly known as Libra) was a permissioned blockchain-based stablecoin payment system proposed by the American social media company Facebook. The plan also included a private currency implemented as a cryptocurrency... The project, currency and transactions would have been managed and cryptographically entrusted to the Diem Association, a membership organization of companies from payment, technology, telecommunication, online marketplace and venture capital, and nonprofits... The project generated backlash from government regulators in the European Union, the USA, other countries, and among the general public over monetary sovereignty, financial stability, privacy, and antitrust concerns which ultimately helped kill the project.[7] The Diem Association (originally the Libra Association) shut down in January 2022 and sold the project to Silvergate Bank. Silvergate wrote off their Diem investment in January 2023. https://en.wikipedia.org/wiki/Diem_(digital_currency)
