Layer 1: Build the Vault
Implement encrypted storage with graph-aware indexes and capability verification. The vault is where user data lives.
Build
Build on JournalNet's three-layer architecture: implement the vault, the cipherlot, or create applications.
Layer 2: Build the Cipherlot
Implement capability tokens, blind relays, and metadata minimization. The cipherlot handles access control and privacy.
Layer 3: Build Applications
Create applications that request temporary, scoped access to user data. Use the SDK to connect to vaults without storing user data.

Development Principles
Open by default
All code, specs, and governance decisions are public.
Privacy-first
Metadata minimization and encryption aren't optional.
Interoperable
Multiple implementations of the same spec should work together.
No platform lock-in
Users can switch apps without losing data.
