A system includes memory hardware that stores an event logging database including entries corresponding to events processed at local servers. The processor hardware executes instructions including, in response to receiving a first message from a first local server (the first message indicates that a first event occurred), identifying a causal parent event preceding the first event. The causal parent event is a most recent event that occurred at the first local server. The instructions include identifying a temporal parent event preceding the first event. The temporal parent event is a most recent event that occurred across all of the local servers. The instructions include generating a new entry based on data from the first message and a cryptographic hash based on a hash of a first entry recording the causal parent event and a hash of a second entry recording the temporal parent event.

Systems and methods for maintaining and updating an event logging database

A method includes maintaining an event logging database including entries corresponding to events processed at local servers. The method includes, in response to receiving a first message from a first local server, where the first message indicates that a first event occurred, identifying a causal parent event preceding the first event. The causal parent event is a most recent event that occurred at the first local server. The method includes identifying a temporal parent event preceding the first event. The temporal parent event is a most recent event that occurred across all of the plurality of local servers. The method includes generating a new entry based on data from the first message, an identifier of a first entry recording the causal parent event, and an identifier of a second entry recording the temporal parent event. The method includes adding the new entry to the event logging database.
