The main developer of Wasabi, Adam Ficsor, stated that the problem is from samourai the lack of randomness in the output of the unspent transaction or UTXOwhen you make the CoinJoin mix selection. He explained that this does not affect anonymity as only the users themselves know all of the UTXOs in their wallet.

Havel noted that Wasabi users using his CoinJoin feature should always know how to manage their UTXOs in such a way that anonymity is preserved:

“Proper privacy protection, especially with tools like currency control, requires some learning and attention. In this case, the user must be aware of possible attack scenarios and avoid them by properly handling UTXOs.”

This statement is in line with the July 2019 reports in which Samourai initially raised concerns about Wasabi’s CoinJoin app. Ficsor said that “the community knows their demands are excessive.” Mário Havel disagrees:

“There have been many more or less sensible clashes in the past, but overall the samurai investigation does a good and interesting job for the Bitcoin privacy ecosystem. Most of the allegations against Wasabi are based on [el problema mencionado anteriormente, que es que] It takes some knowledge to use it properly in private. “

“I personally use both wallets because they each have different features and benefits. […] Both are great services even without the CoinJoin feature and it just depends on the user how they use them and what wallet features they need.
