Physical Lock
Physical Lock defines the software for building a secure physical lock using the Vanadium stack, along with a commmand-line tool for interacting with the lock. The software runs on a Raspberry Pi and interacts with the locks's switches and sensors using GPIO. It runs a Vanadium RPC service that allows clients to send lock and unlock requests.
Key distinguishing aspects:
- Decentralized: There is no single authority on all the locks, no cloud server that controls access to all locks from a particular manufacturer. All secrets and credentials pertaining to a particular lock are solely held by the lock and its clients. Huge compute farms run by hackers all over the world have no single point of attack that can compromise the security of multiple locks.
- No Internet Connectivity Required: The lock does not require internet connectivity to function. When you’re right in front of the device, you can communicate with it directly without going through the cloud or a third-party service.
- Audited: The lock can keep track of who opened the door, when and how they got access.
