Intelligent method to prevent duplicate event processing using a distributed ledger

Abstract

Arrangements for preventing duplicate event processing are provided. A computing platform may train a machine learning engine to determine whether to post an event to a corresponding user account. The computing platform may receive a first event hash corresponding to a first event. The computing platform may query a database to determine whether information in the first event hash matches an invalid key stored in the database. The computing platform may generate a first event block based on the first event hash. The computing platform may validate the first event block by establishing a consensus with one or more event assessment systems. The computing platform may use the machine learning engine to output an even exception score and compare the event exception score to a threshold. The computing platform may post the first event based on the event exception score meeting or exceeding the threshold.
