It's clear that the mainstream use of digital currency is closer than ever before, and especially after the pandemic, the demand for such technology has only gone higher. However, bringing this new technology to the market and expecting everyone in the world to accept and also implement it is a pretty high feat to achieve. It's difficult for the government bodies as well to build an infrastructure that takes care of every aspect of the economy.
But despite all the challenges and struggles, governments all around the world are very much intrigued and involved in making CBDC a possible reality. According to a recent announcement by G20, the IMF, the World Bank, and the BIS are working towards building a proper framework and research on CBDC design and technologies by the end of 2022. Along with this, the IMF and the World Bank are also expected to have a working infrastructure involving CBDC transactions by the end of 2025.
