Quick Start

That's it. Your personal SAND server is running.

What is SAND?

Four protocols, one stack, total sovereignty:

	Protocol	What You Get
S	Solid	Personal data pod — files, profiles, apps
A	ActivityPub	Federated social — Mastodon, Threads, WordPress
N	Nostr	Censorship-resistant social — relays, zaps, keys
D	DID	Decentralized identity — one key, every protocol

---

Why SAND?

The Problem

Your Life	Who Controls It
Identity	Google, Apple, Facebook
Files	Dropbox, iCloud, Drive
Social	Twitter, Instagram, TikTok
Followers	The platform

The Solution

SAND Protocol	What It Fixes
DID	You own your identity
Solid	You own your data
Nostr	You own your voice
ActivityPub	You own your social graph

The Vision

Your phone = Your server
Your key = Your identity
Your pod = Your data
Your relay = Your reach

Zero to sovereignty in 60 seconds.
