Privacy Tamga Wallet team Thu, 08 Oct 2026 09:00:00 GMT https://tamgawallet.com/en/blog/revocation-and-validity https://tamgawallet.com/en/blog/revocation-and-validity Institutions publish document status in a signed list. Your wallet checks it by itself, and the issuer never learns where you showed a document.

A short, plain explanation with a simplified example. Standards Tamga Wallet team Thu, 08 Oct 2026 09:00:00 GMT https://tamgawallet.com/en/blog/selective-disclosure https://tamgawallet.com/en/blog/selective-disclosure Selective disclosure lets you show one field of a signed document, such as "is a student", while the rest stays hidden and the signature still checks out.

Part of that is real today; part still depends on institutions.

Data minimisation under GDPR and KVKK, and how selective disclosure helps. Privacy Tamga Wallet team Thu, 08 Oct 2026 09:00:00 GMT https://tamgawallet.com/en/blog/unlinkability https://tamgawallet.com/en/blog/unlinkability Tamga Wallet gives each verifier its own copy of a document and each site its own pseudonym, so two places can't match you by comparing notes.
