// Package lock defines the interface and implementation

//
// Each lock device runs a Vanadium RPC service that offers
// methods for locking and unlocking it. The Vanadium RPC protocol
// allows clients to securely communicate with this service in a
// peer to peer manner.
//
// The key for a lock is a blessing obtained during lock initialization.
// Only clients that present this blessing or extensions of it have access
// to the lock. Clients can delegate access to the lock to other principals
// by blessing them using this 'key' blessing.
