End-to-End Encryption: What It Actually Protects (and What It Doesn't)
E2E encryption means not even the service provider can read your messages — until you link WhatsApp Web and suddenly a browser has your keys. Here's how the Signal Protocol really works and where the trust boundaries are.
Zero-Knowledge Proofs: Proving You Know a Secret Without Revealing It
Zero-knowledge proofs sound like cryptographic magic — and they kind of are. Here's how they work, where they're already deployed in production systems, and why they matter beyond blockchain.
