Abstract: In a method for securing asset maintenance information, genesis transaction data is generated as a function of manufacturer-specific asset data. A distributed ledger technology (DLT) data structure is generated on the basis of the genesis transaction data. In response to a lifecycle activity relating to the asset, during which maintenance-related asset data is produced, transaction data is generated on the basis of the maintenance-related asset data produced during the lifecycle activity and is added to the DLT data structure. The DLT data structure is distributed to at least one DLT node in order to secure the maintenance-related asset data.
