Yes. In the US context, we already have a digital currency, they're called "US dollars". Something that gets floated periodically is the idea of creating a bank that only accepts deposits, and then sticks them in the Federal Reserve. This is sometimes called "narrow banking", and one of the more prominent efforts to do this involved a proposed bank called The Narrow Bank or TNB. (Alternatively, you could let individuals deposit money directly with the Fed.) If implemented, such accounts would be 100% backed. You have a dollar, you put it in the account, it sits there until you ask for it back.
