Beschreibung
Zusammenfassung:	The invention relates to a blockchain for license keys of variable frequency drives. According to an example aspect of the present invention, there is provided servicing variable frequency drives suchthat servicing history transparency is facilitated. License keys of a variable frequency drive are generated based on a hardware fingerprint of the variable frequency drive, when the hardware fingerprint is changed. The license keys and transactions corresponding to hardware configurations of variable frequency drives are stored in a block chain. 本发明涉及用于变频驱动器的许可密钥的区块链。根据本发明的一个示例性方面，提供了维护变频驱动器，使得有助于维护历史透明。当硬件指纹被改变时，基于变频驱动器的硬件指纹来生成变频驱动器的许可密钥。与变频驱动器的硬件配置相对应的许可密钥和交易被存储在区块链中。
