Following in the footsteps of other countries, like Estonia, for instance, Israel ponders the issuance of a digital currency. Please note the fact that I said "digital" and not necessarily "crypto currency". The problem that they try to solve is not excessive centralization, as this digital currency will obviously be controlled by a central bank, but the black market.
According to the article in Haaretz which broke the news:
Israel’s black-market economy is estimated to be the equivalent of 22% of the country’s gross domestic product. Under-the-table transactions of such magnitude mean that the treasury is losing about 50 million shekels in uncollected taxes annually – an amount almost equal to the country’s education budget.
It's not yet clear if and when this currency will be issued, but it's a symptom of a wide range of problems that the blockchain technology can solve even in a centralized environment.
