Abstract
Providing and using an activity logging service can include registering an activity logging service with a hash ledger storage service that can store a hash ledger that represents an activity log for an entity, and registering an observer device with the activity logging service. The observer device can provide event data to the activity logging service, and the event data can describe an event associated with the entity. The event data can be obtained from the observer device and a block that represents the event can be generated. A block can be added to the activity log, and a hash of a portion of the activity log can be generated and sent to the hash ledger storage service. The hash ledger storage service can be configured to append the hash of the portion of the activity log to the hash ledger that represents the activity log for the entity.
