How divisible are ripples (XRP)? With 100 billion of the currency units being created at system inception one could assume that they are akin to satoshis, but during the operation of the system I found my balance being charged sub-ripple amounts for some operations. How much can one ripple be divided into?
XRP are internally represented as an integer number of millionths of a ripple. No term has yet been accepted for naming these units, but some people have (I think jokingly) referred to them as "Jeds".
Update: It looks like they will be officially referred to as drops as you suggested. A transaction costs 10 drops. There are a million drops in a ripple.
