Abstract
Systems and methods of the present disclosure include receiving an electronic request to exchange data items. A digital asset associated with the exchange of the data items is generated including a vault unique identifier, and an asset owner. An exchange block is generated on an exchange chain to record the electronic request. An asset copy is generated on the exchange ledger chain to record a non-permissioned copy of the digital asset independent from the vault unique identifier. An asset block is generated on an asset ledger chain to record an authoritative copy of the digital asset associated with the exchange of the data items on the exchange chain; where the asset block header includes an asset block hash concatenated with the vault unique identifier associated with the digital asset. The authoritative copy of the digital asset associated with the electronic request is displayed in response to a user selection.
