The Privacy Dilemma of Blockchain: Transparency Turns Out to Be the Problem

Recently, an industry insider proposed an interesting point — current mainstream blockchain network transactions are actually highly transparent, but is this "transparency" really a good thing?

On the surface, it seems so, but in practice, it exposes many issues. For example, front-running (MEV) is a typical side effect. Because all transaction information is visible on the chain, malicious nodes or traders can see your orders in advance and then execute transactions ahead of you for profit. This actually puts ordinary users at a disadvantage.

So the question is: are regulators really opposed to privacy itself? Or are they actually concerned about the risks of privacy being abused? The difference between the two is significant.

Balancing privacy protection and regulatory requirements depends on design choices. It’s necessary to protect users’ transaction privacy while preventing criminals from exploiting privacy for illegal activities. For blockchain project teams and exchanges, this is a design challenge that must be taken seriously.
