An example operation may include one or more of executing a blockchain transaction which generates modifications to an asset, identifying a most recent version of the asset comprising most recent values of the asset before the blockchain transaction, generating a delta block for the executed blockchain transaction identifying differences between the modifications to the asset and the most recent version of the asset introduced by the blockchain transaction being executed while excluding unmodified values of the most recent version of the asset which are not modified by the executed blockchain transaction, and hashing the delta block to generate a hashed delta block and storing the hashed delta block on a distributed ledger.
