Facebook's digital wallet Calibra will not appear in some of the largest social networking markets, including India. A Calibra spokesperson said: "The Libra blockchain will be global, but will be determined by the managed wallet provider where it will operate. Calibra will not be used in countries that are sanctioned by the US or in countries where cryptocurrencies are banned." This also means that the Calibra digital wallet will not land in India's largest Facebook market. In addition, Calibra cannot land in China, North Korea and Iran.
