Blockchain analysis is ultimately a process of deduction and induction.
A process which becomes much easier when the centralized coordinator is actively working with blockchain analysis companies and handing over all the data they collect.
Like I said, the main advantage of Sparrow Wallet is that it never relies on Samourai servers, even when you are not connecting to your personal bitcoin full node. Having not configured to retrieve information from blockchain via your node, it will connect to one of the public Electrum servers as if you were using a regular Electrum wallet. However, in this case, doing mixing is kinda pointless because the Electrum server can learn all pre-mix and even post-mix transactions and learn that they belong to the same wallet.
A genuine question then, since I've never used Sparrow - how do you use it privately? Can you connect it to your own node directly, or do you need to run an Electrum server first? If I'm already running a Samourai Dojo server, can it connect to that instead? Other than platform availability, what are the advantages of Sparrow?
