Schnorr Signatures and Their Privacy Implications

Just read about Schnorr signatures with Taproot. Super cool how they let multiple signatures combine into one for multiSig. Means smaller transactions and lower fees, right? But the privacy aspect is really interesting too. It kinda makes multi-sig look like single-sig, which should make it tougher to track on the blockchain.

Not sure how to explain it all, but check out this thread from HusnaQA. It's really informative.

One thing I found is you can't get a public key from a Schnorr-signed transaction. Plus, you can’t really tell what script is being used when spending Taproot outputs since it’s hashed before hitting the blockchain. This is a big deal for privacy.

I think you might be missing the point. Looking ahead, Taproot could act like a mixer down the line. I’ve seen that Bitcoin devs might turn Taproot transactions into something like coinjoin. But I doubt that’s the main goal. Why focus Taproot on single-sig when multisig could do the same?

That’s a different ballpark. Taproot is about allowing multiple users to send their coins from one address. Coinjoins just gather several addresses into one transaction, making it look like a mixer. Most software already tags coinjoins as mixers. But with Taproot, it’d be all packed into a single transaction, and you'd need special software to set it up.

Got it. I messed up a bit there. Just trying to learn, and I know my questions might seem silly. Appreciate everyone here.

Schnorr and mixers can actually work well together. They can enhance your privacy, but remember, Schnorr doesn’t hide where your funds come from or go. Combining both might make tracing harder. Plus, Schnorr helps cut down transaction sizes, meaning lower fees for mixers too. But you gotta think about convenience and regulations. So yeah, use them wisely.
