When it comes to on-chain privacy, the more I think about it, the more uncomfortable I feel... Everyone talks about "privacy," but in reality, regulations are tightening more and more. For ordinary users, I don't think you should expect anything like "complete anonymity"; with the public ledger on the chain, at most, don't tie yourself too tightly to your address: don't reuse addresses everywhere, don't post transaction records like social media updates, and don't just screenshot your seed phrase and upload it to the cloud for convenience. Frankly, privacy is more about reducing the chance of being easily traced, not about turning invisible just by enabling a certain feature.

And don't expect to fool the compliance boundaries either. Large transactions through fiat channels, deposits and withdrawals on exchanges—sooner or later, you'll have to explain the source. Modularization and the decentralized layer (DA layer) are now making developers excited, but as a user like me, I’m honestly a bit confused: no matter how fancy the chain is built, in the end, it still comes down to me asking, "Where did this money come from, where is it going, and can I prove it's mine?" Anyway, my current expectation is quite simple: expose as little as possible, but don’t do anything that will make future explanations difficult. Better to be a bit more troublesome now and sleep peacefully.
