    Abstract: The present disclosure provides a management method for software versions which prevents falsification of information under management. In the management method, a first management apparatus among management apparatuses receives transaction data from an apparatus connected through a network to the first management apparatus, the transaction data including first information on a first version of software, second information on a second version of the software subjected to version upgrade from the first version by a software developer, identification information of the software developer, and an electronic signature. The first management apparatus validates legitimacy of the transaction data using the electronic signature included in the transaction data received. When the transaction data is legitimate, the management apparatuses store the transaction data in distributed ledgers.
