Lucas Explains Samourai Wallet Infographic Propaganda

by Lucas Ontivero

I don't know about the samurai's version but I can answer about Wasabi coinjoins:

1) No pre-mix, No early fee: yes, that's correct. You pay for what you get so, if you get nothing then you pay nothing. According to this advertising comparison it seems in samurai that is different . Moreover, if samurai creates that splitting TX0 that means that they know all your addresses, what means that it doesn't matter how many times you mix them, they know your wallet anyway. Wasabi doesn't.

I really don't know what the phrase "UTXOs are directly registered to mix without any verification" means. There are a lot of verifications in place. Anyway, yes, you can register your utxos without aditional steps or costs, that's correct.

2) "Wasabi coordinator accepts any UTXOs in the mix". Well, no exactly but nevermind, lets say yes and explain the points:
* "Those with address-reuse, known to belong to the same user". Of course this is true. In fact, the idea is precisely to help users to regain their privacy.
* "Those coming from the same prev-tx, known to have already collaborated(?) together". That's correct.

3) "No remix incentive". Different users need different level of privacy and those that want a higher level are accept to pay more. Again, you pay for what you get. As a side note, wasabi is not experiencing liquidity problems so, we don't need to keep people mixing, but even more important, from a privacy point of view, if users don't leave and keep mixing again and again in a low liquidity tool like the samurai, that's very bad for your privacy because you end mixing always with the same set of people. The ideal situation would be exactly the opposite: to participate in a huge CJ tx, imagine 10000 participants, a leave.

3) No post-mix strategy. We don't prevent users to move all their funds at once, we just let the user know that that can compromise his privacy"

4) Affected Mix. In case Alice spends more than one coin from the same mix, an observer can assume that those spent coins belong to the same user, however the observer cannot know who is that user.
In samourai you don't need to use complex heristics like that because you can seize the samourai's servers and get all the info that you want (remember tx0)
