| # Private Computing Device Active Daemon | |
| The check membership request of Private Set Membership is computing expensive, | |
| and in order to decrease the traffic of checking membership, we store the | |
| device last ping dates of each use case into the preserved file. This daemon | |
| is used to save the device active ping status into preserved file, and retrieve | |
| the device active ping status from preserved file after powerwash. | |
