Blockchain has long been labeled as "completely transparent," but this has become a bottleneck in financial applications. The asset size of trading counterparts, investment strategies, client databases—once these are on-chain and public, it not only harms business secrets but also crosses compliance red lines.

The real question is: how can blockchain ensure secure verification without exposing sensitive data?

This is precisely what some emerging public chains are redefining. Instead of abandoning transparency altogether, they are adopting a different approach with zero-knowledge proofs—allowing the network to verify whether transactions and smart contracts are compliant without revealing underlying data. In other words, financial operations can run on-chain while maintaining the information isolation standards of traditional finance.

Smarter still, these solutions do not use privacy as a shield to evade regulation. Instead, they reserve an audit channel in the architecture design. After obtaining authorization, regulatory agencies can verify the authenticity of transactions. This "selective transparency" breaks the previous black-and-white scenario—no longer a choice between full disclosure or opaque operations, but a controllable and verifiable process.

In the long run, only blockchains truly adapted to financial realities can achieve mainstream adoption. And this path is being gradually paved.
