It would be very unexpected to see that more than 100 billion XRP existed prior to #32570. With current transaction types etc. it is impossible in Ripple to issue more XRP, so the amount in #32570 is the maximum we know about
Is it at all possible that a transaction type existed before #32570 that could have allowed more XRP to be created, and then that transaction type was removed prior to ledger #32570 being published?
To be fair, you guys are asking me all the time about "theoretically possible", "at all possible" etc. - there are a lot of things "theoretically possible" in Bitcoin too. Yes, it is
theoretically possible that this happened (though I cannot think of any reason why it should have and also have not found any evidence for that in any way).
To be fair I, as someone wanting to know more about Ripple, am just asking you simple direct questions in order to never have to go through the back and forth argument I have seen you and acoindr engage in several times on this subject, and your huffy attitude at being asked them just makes me less interested in spending my time in future.
