Disclosed are a method for providing an interface for the interoperation of different types of IoT platform devices, and a system for providing an interface for the interoperation of different types of IoT platform devices. A method for providing an interface for the interoperation of different types of IoT platform devices according to an embodiment of the present invention comprises the steps of: connecting a first blockchain node, which is linked to an IoT platform device, to a blockchain network, when device registration is requested by the IoT platform device; matching an integrated identifier based on a DID granted to the IoT platform device with a unique identifier of the device through the first blockchain node, and recording the integrated identifier in a blockchain ledger; using a second blockchain node connected in advance to the blockchain network and linked to a different type of IoT platform device, to retrieve the unique identifier matched with the integrated identifier from the blockchain ledger when a request for accessing the IoT platform is issued from the different type of IoT platform device; and delivering the access request from the different type of IoT platform device to the IoT platform device identified by the unique identifier on the IoT network.
