According to Article 13 Paragraph 1 of the Asgardian Constitution, the currency to be used in the Space Kingdom of Asgardia will be SOLAR. Now, I ask. Will the currency be the same as earth's where coins and paper bills would be used or will it be on a digital platform. Also, if SOLARs are to be converted into earthly currency, where will its value be based upon, if let's say, it would be implemented as a digital currency?

The most obvious answer to this would be to implement a digital currency instead of going for a traditional approach because 1) it would be a waste of space and resources such as metal or whatever material it is, needed to make coins, and paper; and 2) a digital currency would be more flexible and practical because it would take away the need for credit cards and all that because the debits/credits to the balances can be implemented directly and the credit contracts can be made as such without having to give physical money.

But yes, the question still stands, will SOLARs be physical or digital?
