Could you build this?
Partial Designing a reliable, trustless zero-knowledge digital inheritance system and dead man's switch requires rigorous cryptographic design so third parties cannot access data prematurely while guaranteeing heirs can decrypt it.
What it would actually take: Stack would use Web Crypto API (Argon2id, AES-256-GCM) combined with Shamir's Secret Sharing (SSS) or time-lock puzzle encryption protocols. The challenging part is building an automated, attack-resistant dead man's switch that releases decryption shards to verified beneficiaries upon prolonged inactivity without central servers ever holding the assembled plaintext key. Demands specialized cryptographic architecture and high-assurance backend security engineering.
