Okay, so adding those fancy "ring signatures" to Bitcoin I guess would be a massive deal. We may even need to change how Bitcoin even works at its core, like how transactions point to your money. Wallets would also need a total makeover too.

But honestly, it could make things way slower and more expensive to use. Plus, figuring out how to stop people from cheating (double-spending) with this new system would be a real headache. And of course, all the Bitcoin we have now would just stay the same, this would only affect new stuff. Big changes with some serious downsides to think about.
