I’ve recently been thinking about the differences between Cash and Zcash. And one fundamental thing about cash is that it gets harder to trace the further along in transactions/time you go. People at some forget “oh I got that money to that person”. So with increasing time, it gets harder to deanonymise. Now with Zcash, correct me if I’m wrong, it seems like the opposite. Where the longer this thing is running, the higher the chance of new math being discovered that helps with denaonymising transactions, computers getting faster and in general I don’t see how the zcash blockchain has the property of the further along the chain is, the mathematically harder it would get to denanonymise transactions. So in a way, ZCash could be a risk of denanomisation that only grows whereas with real Cash, it seems like it’s the opposite.
What are your thoughts on this?
Maybe also @zooko ?
