It will harm the privacy gains to recombine mixed UTXOs
Discussion
Thanks for the info... My concern is about the multisig script... If I'm using the same multisig cold wallet, wouldn't it have the same multisig script for the UTXOs prior and after the mix? And could that somehow tie back to the pre-mixed UTXOs?
The multisig script is not unique to you, but it’s definitely something identifiable. If you go in from 4-of-7 multisig and out to 4-of-7 segwit multisig, there’s just not that many people using 4-of-7 segwit multisig so you might stand out in a chain analysis. But it wouldn’t be deterministic still
At least that’s how I understand it, definitely find someone more technical than me before you take my word for it
Really appreciate the insight 🫂🫂
