Yep, Dubai has launched a national crypto-currency and they were thinking of a name and came out with "em....Cash". However it is not the moment to get all excited, basically, as state currency is not decentralised and perhaps is no different from paying with a credit card, except that is far cooler.
The initiative includes a wide variety of public institutions that will be connected to the system in what a appears a very strong support. Perhaps we are looking here at eGovernment initiative in what is one of the most dynamic economies of the region and I think it may very well serve as a bench to test the efficiency that these systems could bring to the financial public sector.
I don´t quite understand however the technical side, since this news states that
"the blockchain deployed is compatible with both public and permissioned blockchains using open-source Hyperledger and public Ethereum tech."https://www.ccn.com/dubai-to-launch-blockchain-payments-with-state-digital-currency-emcash/
