Is there a way to work out coin age or equivalent

Question

I am working on a solution for voting, and I need to work out how long someone has held native currency in the their wallet so I can give voting rights using another token...I want to specify anything older than 30 days - any ideas how I could do this?

Answer 1

This would be another case where you're best served by an off-chain database of transactions, which allows these kinds of analytics. Look for the first transaction in which the user received some native currency to their address.

ah yes, of course..;)...constantly learning if we should be using off-chain or not for different scenarios...
