Could you build this?
No Building a zero-knowledge dead man's switch using cryptographic schemes like Shamir's Secret Sharing requires deep applied cryptography and security engineering to prevent disastrous key loss or premature exposure.
What it would actually take: The architecture requires robust client-side encryption (WebCrypto/libsodium), a multi-party computation or Shamir's Secret Sharing (SSS) key splitting mechanism, and a decentralized or highly fault-tolerant monitoring daemon for the dead man's switch heartbeat. The difficult parts involve provable zero-knowledge security guarantees, secure guardian key recovery ceremony UX, anti-collusion mechanics among guardians, and resilient long-term durability. Specialized expertise in applied cryptography, threat modeling, and fail-safe automation is non-negotiable.
