Built Eternal Vault to solve a widespread problem of digital assets being lost or inaccessible with proper cryptography. 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.
