Abstract
A method may include a device joining a distributed database in a distributed physical access control system. The method may include storing first data in a first memory area of a memory. The first memory area may be designated to store data for a consensus-based distributed database (DB). The first data is to be added to the consensus-based distributed DB that is distributed among other devices in a network. The method may include copying the first data to a second memory area of the memory of the device and adding the device to the network, receiving data from the other devices in the network and adding the received data to the consensus-based distributed DB by storing the received data in the first memory area, and adding the first data to the consensus-based distributed DB by copying the first data from the second memory area to the first memory area.
