Abstract
A method of using a blockchain in an access control environment according to one embodiment includes transmitting, by a mobile device, a request to access a passageway secured by a lock device to a first node device, wherein a plurality of node devices including the first node device store the blockchain, receiving, by the mobile device, a lock-specific access token from one of the plurality of node devices in response to validation of a blockchain transaction associated with the request received from the mobile device by the plurality of node devices, transmitting, by the mobile device, the lock-specific access token to the lock device, receiving, by the mobile device, a verification message from the lock device in response to successful authentication of the lock-specific access token, and transmitting, by the mobile device, a notification of verification to the first node device to amend the blockchain.
