Hidden Surface

Hidden Surface is an independent publication examining privacy as a structural risk in crypto systems.

It focuses on how design choices around wallets, protocols, compliance, and infrastructure quietly accumulate exposure, long before enforcement, incidents, or public scrutiny.

This is not a community forum, a product newsletter, or a commentary feed.
It is a weekly analysis of how system design choices quietly fail at scale, especially when enforcement depends on observation rather than proof.
