Technical approach:
- Client-side AES-256 encryption (plaintext master key never leaves device)
- Shamir's Secret Sharing for access control (3-of-3 threshold)
- Zero-knowledge architecture
- Trust levels distribute key shares to family members
Security model:
- Everything encrypted before network transmission
- Can't decrypt user data even if we wanted to
The problem: Over $200 billion in inaccessible assets worldwide¹, including $140+ billion in lost Bitcoin alone². Government data shows billions in dormant accounts unreachable by families across multiple countries³. 76% of people have no digital estate plan.
What it does:
- Secure storage for wills, passwords, photos, documents
- Smart family access controls with trust levels
- Gamified legacy building with guided checklists
- Business continuity features
Would love feedback on the cryptographic design and threat modeling from the HN community.
