Gauging the attitude of governments and central banks toward cryptocurrency is a challenging task. Some jurisdictions seek to develop their own cryptocurrency systems; this category contains a diverse list of countries including the Marshall Islands, Venezuela, Lithuania, and the member states of ECCB, the Eastern Caribbean Central Bank. As of now, most are unable to support crypto as unregulated currency, although it could become a useful tool. The current banking system is restricted by certain territorial and temporal limits, barriers which blockchain technology has managed to bypass. For instance, it solves the problem of double-spending (verification of the transaction prior to processing to prove the units exist) and transactions can take place anywhere in the world, without location-based commissions.
