IPv4 provides unique features no other protocol has. address space is saturated (scarce) and addresses are not cheap. It is a a nice tool for Sybil control

That's a good one.

tl;dr; planned feature.

Monero, AFAIK, makes it difficult not impossible to trace transactions.
So it adds some obfuscation. If validation nodes are open source at some point in the code they have to do the basic math. Other thing is that this math is done not by all nodes but only some of the nodes. That's the difficulty for a listener node to catch all transactions.

In USPS, as long as the network is big, it makes harder -not impossible- to reconstruct the state from recorded transactions because nodes handle only a fraction of the traffic.

Still, addresses are anonymous, and nodes mix all of them as they arrive, making the equivalent of a big tx with many inputs-many outputs
on every consensus cycle.

Still yes, individual tx can be recorded as they arrive with a trivial patch. This would allow to follow the money across anonymous accounts. And this could lead to potential associations with separate events (e.g. I buy something and then I buy other thing; an observer could find a parallelism using time and sequence to narrow or find out  addresses belonging to me).

I have ideas to tackle these cases which are very real theoretically, although only for a minority of people would result of some real concern (to me is a concern))

To be added in the future, as the concern grows bigger, a mixer implemented as a public algorithm (my name for ~smart contract). With this feature one could use it anytime they can break the potential traceability of their money moves, which is already difficult if the network is big.

Privacy to me falls more on the ability to do real P2P end2end (real end2end) encrypted trades between 2 nodes without awareness of the rest.


Thanks 4 digging
