SAND Stack: Integrate JSS + FedBox + Nostr + DID

[melvincarvalho]

Vision

SAND = Solid + ActivityPub + Nostr + DID

One command to run a complete personal sovereignty stack:

npm install -g sandymount
sandymount start

Components

Letter	Tech	Source	Status
S	Solid	JSS	✅ Ready
A	ActivityPub	FedBox	✅ Ready
N	Nostr	JSS built-in relay	✅ Ready
D	DID	JSS did:nostr → WebID	✅ Ready

Architecture

Phase 1: Orchestration Wrapper

• sandymount npm package depends on javascript-solid-server + fedbox
• CLI wraps both, runs on separate ports
• Shared config file

Phase 2: Single Port Integration

• Merge FedBox into JSS as plugin (like Nostr relay)
• One Fastify instance, one port
• Phone-friendly (~100MB RAM)

Phase 3: Unified Identity

• One keypair for all protocols
• WebID = ActivityPub Actor = Nostr pubkey
• Sign once, federate everywhere

Why This Matters

• Runs on Android/Termux (phone in your pocket)
• No cloud dependency
• Own your identity across Solid, Fediverse, and Nostr
• "Zero to sovereignty in 60 seconds"

• FedBox is Node.js, same runtime, similar patterns
• Both use JSON-LD
