Title: OpenADP Strategy Brief: Unlocking the Missing Link in Sovereign Data Infrastructure
Executive Summary
The current digital ecosystem suffers from a gaping hole between decentralized data ownership (e.g., Solid) and secure, private connectivity (e.g., Tailscale). Whatâ(TM)s missing is a robust, user-friendly, and decentralized authentication and key recovery systemâ"one that operates without trusted intermediaries, respects user agency, and supports encrypted personal backups. OpenADP, as conceived, is uniquely positioned to fill that role.
This brief outlines a focused strategy to:
1. Complete OpenADPâ(TM)s MVP to provide distributed trust-based key protection.
2. Integrate OpenADP into a working reference stack (SolidMesh).
3. Mobilize aligned developers and projects into a growing ecosystem of sovereign tools.
The aim is to inspire the continuation of OpenADP not as a standalone tool, but as the keystone in an architecture that truly empowers end users.

The Opportunity
OpenADP is the rare project that:
Targets a widely felt problem (centralized recovery, mass surveillance, vendor lock-in)
Offers a practical solution using already understood cryptographic primitives
Requires no global coordination, yet provides partial Byzantine fault tolerance
Can be deployed at small scale (e.g., Raspberry Pi tailnet servers) yet serve global users
Most importantly: OpenADP is the missing link in realizing a truly end to end personal sovereignty architecture composed of:
Solid (for decentralized, user-controlled data)
Tailscale (for secure private mesh networking)
OpenADP (for user-held keys and resilient encrypted recovery)

Strategic Phases
Phase 1 â" Deliver a Working MVP of OpenADP
Goals:
Build a functional server-side reference (Python or Go)
Implement PIN-guess limiting and T-of-N Shamir key recovery
Create a CLI or Android demo client for key registration and recovery
Enable devs to self-host protection servers (e.g., on Raspberry Pi in a tailnet)
Outcome:
A usable crypto primitive for encrypting and recovering arbitrary secrets
Demonstrable privacy-respecting flow with no centralized backdoor
Phase 2 â" Integrate with Solid + Tailscale
Goals:
Secure Solid Pod encryption keys with OpenADP during backup
Host protection servers over Tailscale (MagicDNS or tailnet IPs)
Run end-to-end flow: encrypted backup + decentralized recovery + Solid data access
Outcome:
A full-stack proof-of-concept (SolidMesh) usable for encrypted personal data pods
Example: restore a lost encrypted identity vault using a PIN from another device
Phase 3 â" Grow the Ecosystem and Momentum
Goals:
Publish blog posts and example repos showing the SolidMesh architecture
Pitch integration to aligned communities: Nextcloud, Matrix, Proton, Mozilla
Form or join a neutral foundation or working group for data sovereignty tooling
Outcome:
Clear traction around OpenADP and increasing developer contributions
External validation of OpenADP as a foundational cryptographic component
