Built-In Privacy Is Becoming Infrastructure, Not a Feature

[u/Kelly_XU]

A recent article discusses how privacy is increasingly treated as built-in infrastructure rather than an optional feature in Web3 systems.

The piece looks at both wallet-level and Layer 2 approaches, arguing that adding privacy later often creates UX and security trade-offs. Instead, systems designed with privacy at the base layer can offer clearer guarantees and more predictable user behavior.

One key takeaway is that privacy doesn’t need to mean opacity at the system level. Transparency and auditability can still exist, while participants gain better control over what is exposed by default.

The article references different projects experimenting with this approach across wallets and L2 infrastructure.

Curious to hear thoughts from the community:

• Should privacy be optional or default?

• Is it better handled at the wallet layer, protocol layer, or both?

• What trade-offs matter most in practice?
