A one time stealth address as far as I can tell is just using a unique address each time... Something bitcoiners should be doing already, that wallets already push for.
Breaking the tx graph is done with the ring signatures, but even that is not perfect as shown in the video. It's pretty damn good to be clear, but it does leave breadcrumbs.
point taken.
those stealth addresses appear on chain in the ring signatures and theres no way of knowing if theyre decoys or not (unless The Adversary has control of the sending wallet, as in the video).
the combination of the two break the txgraph and are pretty different from just using unique addresses on a transparent chain.
but yeah
its a Blockchain and there's information recorded that can be analyzed.
Churning your outputs just one time already significantly increases privacy.
You can do that with Bitcoin but doesn't make economic sense to do with smaller payments. It will likely get eaten up by tx fees when you go to spend it.
Moneros blockchain also enforces it. You can't accidentally re-use the same stealth address even if you try.
Not being able to perform amount analysis doesn't hurt either.
It doesn't really make economic sense to use on-chain with smaller payments in general.
Sending small amounts to a single address doesn't make a bigger utxo, so you still have dust, just all at the same address.
Lightning solves for that at least.
It does make sense on Monero
Yes, Lightning does solve that (although it brings new issues), but I though we were talking about on-chain addresses
