+excerpt: 'A look at the cryptography behind stealth addresses and why every Wraith payment lands on a fresh one-time address that cannot be linked to the recipient.'
+tags: ['cryptography', 'stealth-payments', 'privacy']
+---
+
+Stealth addresses are the foundation of Wraith Protocol's privacy guarantees.
+
+When a sender makes a payment, the SDK derives a fresh, single-use address from the recipient's meta-address. Funds arrive at an address that has never appeared on-chain before, so outside observers cannot link the payment to the recipient's public identity.
+
+This post walks through:
+
+- How meta-addresses are constructed from spend and view public keys
+- Why the recipient — and only the recipient — can scan and recover the funds
+- How the same scheme maps cleanly onto both EVM and Stellar
+
+The result is private payments that require no interaction from the recipient and no changes to the underlying chain's consensus.

 ### Schema
 
 Contains `items` with `title`, `description`, and optional `link` and `tags`.
+
+## `authors.json`
+
+Powers blog author bylines and the `/blog/author/:id` author pages.
+
+MDX posts reference an author by `id` in their frontmatter (`author: 'lena-vogt'`). The id maps to an entry in this file.
+
+### Schema
+
+```typescript
+interface AuthorsData {
+  [id: string]: {
+    /** Display name shown in the byline and on the author page */
+    name: string;
+    /** Short biography shown on the author page */
+    bio: string;
+    /** Optional avatar URL; if omitted, initials are rendered */
+    avatar?: string;
+    /** Optional profile links rendered on the author page */

+    };
+    /** When false the author collapses to "Wraith Team" and has no public page */
+    optIn: boolean;
+  };
+}
+```
+
+Opted-out authors (those in `authors-optout.json` or with `optIn: false`) collapse to the "Wraith Team" label in post bylines and never generate a page. Unknown author ids fall back gracefully to the raw string with no link.
+
+## `authors-optout.json`
+
+A flat array of author ids that should never get a public author page and collapse to "Wraith Team" in bylines.
