Team Builds Zero-Dependency Crypto Dead Man's Switch Using Pure Python

A three-member team called FemTech built Quorum, a CLI and local web dashboard that acts as a dead man's switch for cryptocurrency wallets, developed during a 72-hour hackathon. The tool uses Shamir's Secret Sharing to split a wallet secret into multiple pieces, requiring a minimum number of trustees to reconstruct it only if the owner stops checking in. The entire project runs on Python's standard library alone, with an intentionally empty requirements.txt, replacing pip-installable packages like secretsharing and pycryptodome. A built-in Canary Trap generates decoy shares that trigger an alert if a leaked or coerced share is submitted during reconstruction. Share delivery uses Diffie-Hellman key exchange based on RFC 3526 Group 14 parameters, ensuring the secret itself is never transmitted in recoverable form.
