Lots of great "why coinjoin" and "why privacy" thought threads in here.

Part of this is to actively obscure particular transactions. But it would also be nice to have average transactions stand out less by breaking the common input ownership heuristic with payjoins. If chain analysis can no longer tell who is the receiver and who's sending, it passively benefits the privacy of everyone - saves on utxos consolidations too.

I think payjoin only works along with coinjoins

If you mean you can’t payjoin without doing a coinjoin, that’s not true. Payjoin is just the sender interacting with the receiver to create a tx that pays the receiver, allowing the receiver to add additional inputs of their own (if I’m not mistaken).

No, I mean if you only use payjoin it's still pretty easy to track. If payjoin were in every wallet that would be different.

Thanks for sharing this

Just saw this

One might think that using bitcoin makes it difficult to find those responsible through the protests – at least through their financial transactions. But this isn’t the case. Bitcoin transactions are recorded on the ledger, and the ledger is public. Anyone can download it, view it, and analyze it. And while the ledger doesn’t contain people’s identities or locations, it is subject to analysis and often yields identifying information.

Imagine if Bitcoin core devs had implemented more privacy on the base layer in the early years instead of punting... We wouldn't need the Free Samourai hashtag (just passed 300 days BTW) because paid coinjoin implementations for the base layer wouldn't have needed to exist. But we've already seen that when you offer true privacy, like the devs of Monero did, they get delisted from exchanges. And people prefer NGU more than privacy IMO... So that was a non-starter. So now privacy is being pushed to second and third layers (LN, Liquid, e-cash etc.) with devs of coinjoins being targeting for helping to pass data packets between UTXO holders... Fucked up world... I hope the DoJ gets their shit together under Trump and stops persecuting the Samourai Wallet developers
