The Estonian central bank launched a multi-year project into central bank digital currency.
The central bank said:
"The aim of [the] research project is to investigate how suitable a solution based on the KSI Blockchain, a core technology of e-government in Estonia, could be for operating the digital money infrastructure of a central bank. The same project will also examine new payment solutions that could be made possible by using electronic identity and other Estonian e-government solutions. The research project will not make choices about the use of specific individual technologies."
