Aspects of the disclosure relate to implementation of a recursive hierarchic blockchain for event validation and processing. A computing platform may receive event data from first and second data sources. The computing platform may store, in a first distributed ledger, an event record for each event from the first data source and may store, in a second distributed ledger, an event record for each event from both data sources. In response to determining that a validation condition for a current block of the second distributed ledger has been satisfied, the computing platform may compute a hash and generate a numeric representation of the first distributed ledger. In a new block of the second distributed ledger, the computing platform may store the hash and the numeric representation. The computing platform may write, to the new block of the second distributed ledger, additional event data from both data sources.
