Abstract
An access control system that includes Internet of Things sensors and a controller within a controlled area. The controller is configured to detect a guest device for a guest, to link a guest block chain account with the guest, to identify a sponsor associated with the guest, and to identify a sponsor block chain account for the sponsor. The controller is further configured to publish an access control contract to the block chain. The access control contract includes executable instructions for publishing a transaction in the block chain transferring a validation token from the sponsor block chain account to the guest block chain account and conditions linked with the executable instructions. The controller is configured to determine whether the conditions have been satisfied and to send a trigger message that triggers the access control contract to execute the instructions in response to determining the conditions have been satisfied.
