- **Details:** Web3 & Datenschutz · 5. Juli 2026

Apple betreibt FHE auf Millionen iPhones und Google Wallet beweist dein Alter mit ZK, und trotzdem scheitern die meisten Projekte, die mit der Technologie starten. Der Entscheidungsbaum, die ehrlichen 2026er-Kostenzahlen, und die fünf Failure-Modes, die wir in Privacy-Tech-Builds sehen.

### [Zero-Knowledge-Proofs 2026: Was wirklich production-ready ist](/de/blog/zero-knowledge-proofs-production-2026/)

- **Details:** Web3 & Datenschutz · 5. Juli 2026

Einen Ethereum-Block zu beweisen fiel in einem Jahr von 1,69 Dollar auf unter 4 Cent, und ZK-Identity landete in Google Wallet. Auf welchen zkVMs man baut, was Proving kostet, was auf einem Phone funktioniert, und wo die Security-Leichen begraben liegen.
